Introduction

Decentralized finance (DeFi) lending is the fastest growing sector of the cryptocurrency industry and has shown the potential to revolutionize traditional finance by adding an emphasis on technical innovation and increased usability. By leveraging blockchain technology, DeFi lending provides an alternative financial infrastructure that operates in a decentralized, transparent, and secure manner, enabling users to lend money and optimize their credit investments in a way that was previously impossible (Chirag, 2022).

It is worth noticing that despite several crypto market setbacks in 2022, the DeFi lending sector managed to keep $10 billion (USD) as Total Value Locked (TVL) (Bitcoin.com, 2023).

As users can lend and borrow assets in a peer-to-peer manner without the need for intermediaries such as banks or financial institutions, DeFi lending offers a more efficient and cost-effective system, with lower fees, faster transactions, and increased accessibility while giving users a much better control over their assets and investments. In addition, instead of holding the assets in custody of third-party intermediaries, users have full control over their funds being able to access them at any time (Ethereum.org, n.d.). This, in turn, provides users with more control on the opportunities to earn returns on their investments and access to a wider range of investment opportunities.

On the other hand, multi-chain protocols are becoming an increasingly complementary and scalable important aspect of the DeFi ecosystem. Multi-chain lending is designed to support multiple different blockchain networks, allowing for borrowing and lending interoperability between different blockchain platforms.

The growing popularity of DeFi has led to the development of numerous blockchain networks, each with its own unique set of features, advantages, and limitations. By leveraging multi-chain structures, DeFi lending can be seamlessly integrated across multiple blockchain networks providing users with access to a wider range of DeFi lending/borrowing alternatives, which range from more staking or yield farming alternatives to more native tokens to one blockchain (Leighton, 2022) giving users more decision power when it comes to DeFi investments and credits as they can select more currencies and interest rates on return.

Multi-chain systems also offer improved security, scalability, and flexibility compared to single-chain solutions. By leveraging multiple blockchain networks, multi-chain protocols can provide a more robust and resilient infrastructure that is better able to withstand network disruptions and security threats. Given the increased concerns about the security and robustness of lending protocols following the attacks that have caused loss of funds (e.g. dForce $25 million, Yearn Finance $11 million, Akropolis $2 million losses due to attacks in 2020), there’s an urgent demand for DeFi lending protocols to implement robust security measures and system structures to ensure that their financial services are secure and resistant to hacking.

The growth of institutional DeFi is being facilitated by a number of developments in the blockchain and DeFi space, especially the ones that increase the confidence of investors in the technologies, and more importantly, the ones that are mature enough to scale and provide an interconnected network of financial services to users.

In tandem with these developments, institutional DeFi has been growing rapidly in recent years as more traditional financial institutions, including banks, investment firms, and hedge funds begin to explore the potential of blockchain technology for financial transactions. In 2022 a survey by Celen Network revealed that 81% of institutional investors are comfortable with storing or handling their monetary assets in a tokenized form. Also, 91% of them said that they are interested in investing in tokenized assets.

The increasing interest in multi-chain and lending DeFi technologies paired with the recent interest uptake of institutional DeFi builds a case for a blockchain protocol that leverages the advantages of these currently existing applications, while accommodating for institutional investors' needs. This intersection has the possibility to bring the necessary DeFi scalability that has been desired since its conception.

From lending protocols not being user-centric building on weaknesses of existing platforms due to multiple security attacks that cross-chain bridges have suffered, through product iteration, customer-centric principles, and decentralized financial settlement theory, AS Labs has analyzed the weaknesses of the current structures and - based on the results of this analysis - developed MultichainZ, a scalable user-centric institutional-ready multi-chain lending protocol.

Problems with Existing Multi-Chain and Lending Protocols

The current technological and scalability industry problems that MultichainZ is aiming to solve are:

  • Poor user experience: As of now, open and uncensored access to global DeFi apps has been hindered by a complicated interface, confusing staking processes, and confusing understanding and accessibility regarding yield farming functions. Users of most platforms experience a sub-par experience with complicated layouts and poor documentation frustrating.

  • Even though Uniswap is the first really popular Decentralized Exchange (DEX), users have criticized its user interface as being hard to understand and not being informative about the platform insights (e.g., returns for specific pairs, liquidity of the pools, etc., Addison, 2020).

  • Compound, the first ever dApp to achieve $1 billion in Total Value Locked (TVL), is one of the dApps that DeFi and crypto beginners complain the most about. The most recurring issue is that the interfaces fail to explain simple intuitive actions, such as connecting a wallet or locking funds into any pool.

Based thereupon the vision of MultiChainz is to provide retail, institutional, and experienced crypto users with a lending platform that put their needs at the center of product development, while creating an inclusive platform in which MultiChainz will be the next massive scalable financial application for transparent lending applications.

MultiChainz is a money-market optimized, decentralized borrowing and lending solution that provides cross-chain interoperability amongst lending pools, institutional-ready features, extra secure infrastructures, and efficient loan risk management for its users. To ensure liquidity sufficiency in all its lending pools, MultiChainz also offers an efficient and inclusive yield farming option for users to select the decentralized savings mechanism that best works for them. In addition to the non-native token lending,, MultiChainz offers Non-Fungible Tokens (NFTs) and Real-World Assets’ (RWAs) lending within its infrastructure, which prompts the protocol for mass scalability, where tokenized Real-World Assets’ revolution takes off within the DeFi industry.

The main elements of MultiChainz are:

  • Efficient Money Markets: MultiChainz backbone will be Compound-style money markets, where users deposit assets into liquidity pools, which are then made available for borrowing by other users. Interest rates are determined by supply and demand dynamics, incentivizing lenders and borrowers to participate in the market. The smart contracts of the money markets will ensure that lending transactions settle without a central authority, which will allow efficient and fast NFT, RWA, and cross-chain token lending for users. The MultiChainz money markets will embed loan management mechanisms that reduce the risk of default for borrowers and give more funds’ security to lenders.

  • Cross-Chain Pools: Cross-chain structuring will enable users to lend and borrow assets across different EVMs, such as Ethereum, Binance Smart Chain, Avalanche, etc. This approach will increase the accessibility and liquidity of lending markets by allowing users to interact with multiple blockchains seamlessly. MultiChainz’s cross-chain ecosystem will have a native bridge integration, which will enable it to borrow and lend across different supported chains, removing the two-step need to firstly bridge tokens to the selected network and then borrowing or lending your assets in that committed network.

  • Institutional Lending: Compliance features, such as Know Your Customer (KYC) verification, institutional grade assets’ custodian, and verified borrowing/lending counterparties, will make MultiChianz accessible for traditional financial entities, such as hedge funds, investment banking corporations, asset managers, or pension funds. These institutions will be able to leverage the MultiChainz platform to access liquidity, diversify their portfolios, and manage lending risk more efficiently due to the increased transparency advantages that borrowing/lending through a blockchain brings. MultiChainz institutional solution will provide enhanced security, compliance, and reporting features to meet the unique requirements of institutional clients ready to adopt DeFi.

  • Risk-Efficient Lending: Risk-efficient mechanisms will optimize the risk-reward ratio for both lenders and borrowers. This approach will use advanced algorithms and data analysis to limit the loan risk of borrowers and collateral, enabling MultichainZ’s users to access automatic risk-management mechanisms for their loans and funds. MultiChainz aims to minimize defaults and maximize returns for lenders while providing borrowers with more favorable borrowing conditions.

  • NFT Lending: MultiChainz will allow users to lend and borrow unique digital assets, such as digital art, collectibles, or virtual real estate. We envision NFT lending as a preferred feature that allows users to unlock the value of their NFTs by using them as collateral for loans, while borrowers can access these unique assets without purchasing them outright thus significantly increasing the NFT liquidity.

  • RWA Lending: MultiChainz’s Real-World Asset (RWA) lending protocol will bridge the gap between traditional finance and decentralized finance by tokenizing real-world assets, such as real estate, commodities, or bonds. These tokenized assets then can be used as collateral to obtain loans on MultiChainz, thus, providing users with access to immediate liquidity in a liquid market while using the real value of their physical assets as collateral.

  • Yield Farming: MultiChainz’s yield farming will provide users a service where they can deposit their digital assets into liquidity pools to earn passive income in the form of interest, rewards, or native tokens. MultiChainz’s farming alternative can provide users with personalized savings schemes, where they can choose any tokenized asset and staking terms to earn passive income with the value of their locked assets.

The Money Market MultiChainz Infrastructure

At the core of the MultiChainz Protocol are Compound-style money markets, which enable users to deposit assets into liquidity pools. These pools are then made available for borrowing by other users, with interest rates determined by supply and demand dynamics. This system incentivizes both lenders and borrowers to participate in the market, creating a thriving ecosystem of financial transactions.

The smart contracts governing the money markets ensure that lending transactions settle without the need for a central authority. This decentralized approach allows for efficient and fast lending of non-fungible tokens (NFTs), real-world assets (RWAs), and cross-chain tokens. Additionally, the MultiChainz money markets incorporate loan management mechanisms that reduce the risk of default for borrowers and provide greater security for lenders.

Technical Architecture

The technical architecture of MultiChainz is a robust framework that ensures the seamless operation of its decentralized lending platform. It is designed to provide a secure, efficient, and interoperable platform for lending and borrowing across multiple blockchain networks. This architecture is built around several key components, including smart contracts, liquidity pools, interest rate models, loan management mechanisms and cross-chain compatibility.

Smart Contracts:

The MultiChainz smart contracts govern the aspects of the money markets including user deposits, management of liquidity pools, calculation of interest rates, and facilitation of borrowing and repayment transactions and are designed to ensure efficient transaction settlement providing high transparency as each transaction is secured to be settled with verified parties. Moreover, the smart contracts are audited and tested rigorously to ensure their security and reliability, minimizing the risk of vulnerabilities and exploits.

Liquidity Pools:

(GRAPH)

Liquidity pools are the foundation of the MultiChainz money markets. Users deposit assets into these pools, which are then made available for borrowing by other users. Each liquidity pool is associated with a specific asset, such as an NFT, RWA, or cross-chain token. The total value of the assets in a liquidity pool determines its overall liquidity, which in turn influences the interest rates for borrowing and lending.

Liquidity pools are fully decentralized and autonomous, where anyone can initiate a liquidity pool for any given asset and anyone can choose to provide liquidity for each existing pool. Moreover, aside from the institutional solution, anyone can request to access the funds of the liquidity pool if they meet the collateral requirements automatically set for that specific asset.

Interest Rate Models:

The MultiChainz Protocol employs a dynamic interest rate model that adjusts based on supply and demand within the money markets. When the demand for borrowing an asset is high, the interest rate will increase, incentivizing more users to deposit that asset into the liquidity pool. Conversely, when the demand for borrowing is low, the interest rate will decrease, encouraging more users to borrow from the pool. This dynamic interest rate model ensures that the money markets remain balanced and efficient, with sufficient liquidity to meet the needs of both lenders and borrowers.

Loan Management Mechanisms:

To reduce the risk of default and provide greater security for lenders, the MultiChainz Protocol incorporates several loan management mechanisms. These include:

  • Collateralization: Borrowers are required to provide collateral in the form of other assets when taking out a loan. This collateral serves as a guarantee that the borrower will repay the loan, and can be liquidated if the borrower fails to meet their repayment obligations.

  • Liquidation: If a borrower's collateral falls below a certain threshold, their loan can be liquidated by other users. This process involves the sale of the borrower's collateral to repay the outstanding loan, ensuring that lenders are protected from potential losses.

  • Loan-to-Value (LTV) Ratios: The MultiChainz Protocol enforces strict LTV ratios for loans, which determine the maximum amount a user can borrow based on the value of their collateral. This helps to mitigate the risk of default by ensuring that borrowers maintain sufficient collateral to cover their outstanding loans.

Benefits of MultiChainz Money Markets

The MultiChainz Protocol offers several key advantages over traditional financial systems, making it a more efficient and secure solution for money markets:

  • Decentralization: By eliminating the need for a central authority, the MultiChainz Protocol provides a more transparent and secure environment for financial transactions. Users can trust that their assets are being managed fairly and securely, without the risk of manipulation or interference from third parties.

  • Speed and Efficiency: The smart contracts and blockchain technology underpinning the MultiChainz Protocol enable fast and efficient transactions, reducing the time and cost associated with traditional lending and borrowing processes.

  • Accessibility: The MultiChainz Protocol is open to anyone with an internet connection, providing a global platform for users to access financial services and participate in money markets. This democratization of finance has the potential to drive financial inclusion and empower individuals and businesses worldwide.

  • Innovation: By supporting NFTs, RWAs, and cross-chain tokens, the MultiChainz Protocol is at the forefront of innovation in the DeFi space. This enables users to access new financial products and services, driving growth and adoption within the industry.

Cross-Chain Lending Overview

Cross-chain lending is a crucial feature of the MultiChainz Protocol, as it allows users to access liquidity and financial services across various blockchain networks. This interoperability is achieved through the integration of lending pools with bridge technology, which facilitates the transfer of assets between different chains. By enabling cross-chain lending, the MultiChainz Protocol provides users with greater flexibility and access to a wider range of assets and liquidity pools.

Cross-Chain Lending Pools

The MultiChainz Protocol's cross-chain lending pools are designed to work seamlessly with the bridge technology, enabling users to lend, borrow, and trade assets across multiple chains. Each lending pool is associated with a specific asset and is connected to a bridge contract that facilitates the transfer of that asset between chains.

When a user deposits an asset into a lending pool on one chain, the bridge contract locks the asset and converts an equivalent amount of tokens on the target chain. These tokens can then be used to participate in the lending pool on the target chain, allowing users to lend and borrow assets across different networks.

The process of transferring assets between lending pools on different chains involves the following steps:

  • Asset Locking: The user deposits their asset into the lending pool on the source chain. The bridge contract locks the asset, ensuring that it cannot be accessed or manipulated during the transfer process.

  • Token Conversion: The bridge contract converts an equivalent amount of tokens on the target chain on the backend, representing the locked asset. These tokens are then credited to the user's account on the target chain.

  • Lending Pool Participation: The user can now use the converted tokens to participate in the lending pool on the target chain, lending, or borrowing assets as desired, without the need for him to see the cross-chain conversion of borrowed or supplied tokens on their end.

  • Asset Redemption: When the user wishes to withdraw their assets, they can redeem the tokens in the lending pool on the target chain. The bridge contract will then unlock the corresponding amount of assets on the source chain and return them to the user.

Cross-Chain Multi-Layer Security

Through the adoption of cross-chain lending pools, MultiChainz can provide increased security for lending through:

  1. Diversification: By leveraging multiple blockchain networks, MultiChainZ can reduce the risk of a single point of failure. In the event of a security attack on one blockchain network, the other networks in the multi-chain infrastructure will continue to operate normally, providing a more robust and resilient lending ecosystem.

  2. Improved decentralization: MultiChainZ cross-chain infrastructure can help to distribute the network load across multiple blockchain networks, increasing the decentralization of the lending ecosystem and reducing the risk of a 51% attack. The key advantage is that MultiChainz will be cross-chain since its early development stages, thus, it will allow for a better decentralization as users from different networks gain control of the protocol governance.

  3. Cross-chain security: MultiChainz will also enable cross-chain security measures, such as cross-chain consensus and cross-chain smart contract execution, to ensure that assets are secure across multiple blockchain networks. This adds an additional layer of security to the ecosystem as it avoids loan attacks targeted to 100% of the protocol funds, instead only fragmented percentages of the funds are vulnerable in case of an attack.

  4. Enhanced security features: MultiChainz incorporates enhanced security features from different blockchain networks, such as smart contract auditing and formal verification, to further improve the security of DeFi lending. Given the current trend of flash loan attacks, bridge exploitation, and many other security weaknesses in protocols, MultiChainz offers the most secure cross-chain lending infrastructure through many backend security layers.

NFT Lending

One of the key innovations of MultiChainz Protocol is its support for Non-Fungible Token (NFT) lending, which allows users to leverage their unique digital assets to access liquidity and participate in the DeFi ecosystem. This whitepaper section provides an in-depth look at the process and technical features of NFT lending within MultiChainz.

NFT Lending Overview

NFTs have gained significant attention in recent years due to their unique properties and potential use cases. Unlike fungible tokens, which are interchangeable and have a fixed value, NFTs represent one-of-a-kind digital assets, such as art, collectibles, or virtual real estate. This uniqueness makes NFTs particularly valuable and sought-after, creating a growing market for NFT lending.

MultiChainz enables users to lend and borrow NFTs through its innovative money market system. By depositing NFTs into liquidity pools, users can access loans in the form of fungible tokens, which can then be used for various purposes, such as trading, staking, or participating in other DeFi platforms. This process allows NFT holders to unlock the value of their assets without having to sell them, providing a new avenue for liquidity and financial flexibility.

NFT Smart Contracts

The foundation of NFT lending within the MultiChainz is a series of smart contracts that govern the creation, management, and transfer of NFTs. These contracts are responsible for ensuring the uniqueness and provenance of each NFT, as well as facilitating the lending and borrowing process. By leveraging blockchain technology, these smart contracts provide a transparent, secure, and tamper-proof system for managing NFT lending.

NFT Liquidity Pools

Similar to the liquidity pools used for fungible tokens, NFT liquidity pools within the MultiChainz Protocol allow users to deposit their NFTs and make them available for borrowing. Each NFT liquidity pool is associated with a specific NFT type or collection, ensuring that borrowers can access the specific assets they require. To incentivize users to deposit their NFTs into liquidity pools, MutliChainz offers rewards in the form of governance tokens. These tokens can be used to participate in the governance of the platform, as well as for staking or trading on other DeFi platforms.

NFT Lending Process

The NFT lending process within the MultiChainz Protocol consists of several key steps:

  1. NFT Deposit: Users deposit their NFTs into the appropriate liquidity pool, making them available for borrowing. In return, they receive governance tokens as a reward for providing liquidity.

  2. Collateralization: Borrowers must provide collateral in the form of fungible tokens or other NFTs when requesting a loan. This collateral serves as a guarantee that the borrower will return the borrowed NFT and helps to mitigate the risk of default.

  3. Loan Approval: Once the collateral has been provided, the smart contracts governing the NFT lending process will approve the loan and transfer the borrowed NFT to the borrower's wallet.

  4. Loan Repayment: Borrowers are required to repay their loans within a specified time frame, along with any interest accrued during the loan period. Upon successful repayment, the borrower's collateral is returned, and the borrowed NFT is transferred back to the liquidity pool.

  5. Liquidation: If a borrower fails to repay their loan within the specified time frame, their collateral may be liquidated to cover the outstanding debt. This process ensures that lenders are protected from potential losses and maintains the overall stability of the NFT lending market.

NFT Lending Technical Architecture:

To facilitate the NFT lending process within the MultichainZ Protocol, a robust technical architecture is required. It incorporates smart contracts, decentralized storage, and blockchain interoperability:

  1. Smart Contracts Layer:

  • NFT Deposit: Smart contracts are deployed on the underlying blockchain network to handle the NFT deposit process. These contracts validate and store information related to NFT deposits, including ownership, metadata, and reward distribution.

  • Collateralization: Smart contracts enforce the collateralization process, ensuring that borrowers provide the required collateral in fungible tokens or other NFTs. These contracts verify the value of the collateral and establish the terms and conditions for the loan.

  • Loan Approval: Smart contracts govern the loan approval process, verifying the collateral and transferring the borrowed NFT to the borrower's wallet upon successful collateralization. These contracts manage the ownership transfer and enforce loan terms.

  • Loan Repayment: Smart contracts track the loan repayment schedule and handle the repayment process. They calculate the outstanding amount, including accrued interest, and ensure the return of collateral and borrowed NFT upon successful repayment.

  • Liquidation: In case of default, smart contracts initiate the liquidation process. They evaluate the value of the collateral and automatically liquidate it to cover the outstanding debt. Liquidation ensures the integrity of the lending pool and protects lenders.

  1. Decentralized Storage:

  • Metadata Storage: The architecture incorporates decentralized storage solutions, such as IPFS (InterPlanetary File System), to store NFT metadata. Metadata includes information about the NFT's attributes, provenance, and other relevant details. Decentralized storage ensures data availability and resilience.

Document Storage: In addition to NFT metadata, the architecture may utilize decentralized document storage solutions to store loan agreements, repayment schedules, and other relevant documentation. This enhances transparency and immutability while allowing efficient access to necessary records.

  1. Blockchain Interoperability:

  • Multichain Support: MultichainZ leverages interoperability protocols or solutions to support multiple blockchain networks. This allows borrowers and lenders to interact with the NFT lending process on various compatible blockchains, increasing accessibility and market reach.

  • Cross-Chain Asset Transfer: The architecture includes mechanisms for cross-chain asset transfers, enabling borrowers to collateralize assets from one blockchain network while borrowing NFTs from another. This ensures flexibility and expands the range of available collateral options.

4. User Interfaces:

  • Web/Mobile Applications: User interfaces are developed as web or mobile applications, enabling borrowers and lenders to interact with the NFT lending process seamlessly. These interfaces provide functionalities for NFT deposit, collateralization, loan request, repayment, and monitoring of loan status.

  • Wallet Integration: Integration with blockchain wallets allows users to connect their wallets to the NFT lending platform securely. This enables easy access to NFTs, collateral, and borrowed assets, as well as transaction signing for interactions with smart contracts.

NFT Valuation and Pricing

Use of Oracles:

  • Price Feeds: The MultichainZ architecture may incorporate decentralized oracles to provide accurate price feeds for NFT valuation, collateral assessment, and liquidation processes. These oracles receive real-time market data from various sources to ensure fair and reliable asset valuation.

  • Historical Sales Data: Oracles linked to MultichainZ may fetch historical sales data of similar or related NFTs from different marketplaces and provide this information to MultichainZ smart contracts. This data can be used as a reference point for determining the value of an NFT based on past transactions.

  • Reputation Index: Oracles pull data from external sources that track the reputation and social following of NFT creators. This Index could influence the valuation of NFT’s made by a particular creator. The pricing data extracted from the index is relayed by the oracle directly to the MultichainZ smart contracts which use that data to determine each NFT value.

One of the key challenges in NFT lending is determining the value of the underlying assets. Due to their unique nature, NFTs can have widely varying values, making it difficult to establish a standardized pricing model. To address this issue, MultiChainz employs a combination of on-chain and off-chain data sources to determine the value of each NFT

On-chain data sources include historical transaction data, such as previous sale prices and trading volumes, which can provide valuable insights into the market value of an NFT. Off-chain data sources, such as expert appraisals and market indices, can also be used to supplement on-chain data and provide a more comprehensive view of an NFT's value.

By combining these data sources, MultiChainz can establish a fair and accurate valuation for each NFT, ensuring that the lending process remains transparent and equitable for all users.

Multichainz Oracle Implementation:

Architecture:

An oracle includes two components: an on-chain oracle (a smart contract) and an off-chain oracle service (node.js server).

The on-chain oracle is a smart-contract that has a public function, createRequest, that receives the URL, to query, and the attribute to retrieve. And then, launches an event to alert the off-chain oracle of a new request.

The off-chain oracle is composed of several node.js services deployed by different parties that will query the API and return to the contract the response.

The on-chain oracle then verifies if the minimum number of equal responses has been reached and if so emits an event saying that it has achieved consensus on the value so that the client smart-contract (MultichainZ smart-contract) that queried the oracle knows that it has its response.

Interacting with Decentralized Oracles:

  • Deposit tokens that will be used to pay the node owners. This deposit is made by creating an oracle subscription.

  • Then, Multichainz contracts call the appropriate Oracle Contract, specifying the data needed and setting the number of tokens Multichainz is willing to pay for it. Available nodes will bet against each other to match the token reward and the data the smart contract needs at the best price. Once the node provides the data, the node operator will receive the agreed payment.

Using Oracles with Multichainz Contracts:

When a blockchain application needs off-chain data, it requests data information to the Oracle network through a Requesting Smart Contract (Multichainz smart-contract). On the blockchain , the oracle establishes a smart contract called Service Level Agreement (SLA) contract. There are three subcontracts under the SLA contract:

  • The Reputation Contract is in charge of authenticating an oracle node’s track record, as well as its authenticity and performance history. It filters out untrustworthy or shady oracle nodes based on its judgment.

  • The Order-Matching Contract sends the Blockchain’s data request to the verified oracle nodes and then returns their bids. It then approves the appropriate number and type of nodes in order to fulfill the data request.

  • The Aggregating Contract sends data requests to the DON’s oracle nodes, but these requests are written in an on-chain programming language. As a result, the nodes employ software to convert the on-chain language into an off-chain programming language that real-world data sources can read. This translated version of the request is then sent to an external API that collects the data from the real-world source. The data retrieved from the API is again translated back to on-chain language and sent back to the Aggregating contract.

By incorporating these subcontracts into the SLA contract, MultichainZ ensures a robust and secure integration of oracles with its smart contracts. The Reputation Contract filters out untrustworthy oracle nodes, the Order-Matching Contract optimizes the selection of oracle nodes, and the Aggregating Contract facilitates the retrieval and translation of off-chain data.

MultiChainz represents a significant advancement in the world of decentralized finance, offering a more efficient, secure, and accessible solution for NFT lending.

Real-World Asset Lending

MultiChainz also enables Real-World Asset (RWA) lending, allowing users to leverage tokenized real-world assets, such as bonds, coupons, and other financial instruments, to access liquidity and participate in the DeFi ecosystem. This section explains an in-depth look at the process and technical features of RWA lending within MultiChainz, as well as the platform's partnerships with third-party tokenization providers and institutional partners.

Real-World Asset Lending Overview

Real-world asset (RWA) lending is a crucial component of MultiChainz, as it bridges the gap between traditional finance and the DeFi ecosystem. By tokenizing real-world assets, users can access loans and other financial services on the blockchain, while institutions can tap into the growing DeFi market to raise capital and manage their assets more efficiently.

MultiChainz enables RWA lending through two primary mechanisms:

  • Tokenized Real-World Assets: MultiChainz partners with third-party providers to tokenize real-world assets, such as bonds, coupons, and other financial instruments. These tokenized assets can then be used as collateral for loans within the MultiChainz ecosystem.

  • Institutional Partnerships: MultiChainz works with institutions to list their funds or company initiatives on the platform. Users can contribute funds to a communal pool, which represents the total value of the loan that the institution can obtain. In return, institutions report the returns of their funds or initiatives, allowing pool providers to earn a share of the profits.

Tokenization of Real-World Assets

The tokenization of real-world assets is a critical step in the RWA lending process within the MultiChainz Protocol. By partnering with third-party providers, MultiChainz ensures that real-world assets are accurately represented on the blockchain, allowing users to access loans and other financial services using these tokenized assets as collateral.

Tokenization involves the creation of digital tokens that represent ownership of a real-world asset. These tokens can be traded, transferred, and used as collateral within the MultiChainz ecosystem, providing users with a seamless and secure way to access liquidity and participate in the DeFi market.

RWA Liquidity Pools

Similar to the liquidity pools used for NFT lending, RWA liquidity pools within the MultiChainz Protocol allow users to deposit their tokenized real-world assets and make them available for borrowing. Each RWA liquidity pool is associated with a specific asset type or financial instrument, ensuring that borrowers can access the specific assets they require.

To incentivize users to deposit their tokenized real-world assets into liquidity pools, the MultiChainz Protocol offers rewards in the form of governance tokens. These tokens can be used to participate in the governance of the platform, as well as for staking or trading on other DeFi platforms.

Institutional Partnerships and Communal Pools

MultiChainz establishes partnerships with institutions to list their funds or company initiatives on the platform. Users can contribute funds to a communal pool, which represents the total value of the loan that the institution can obtain. This process allows institutions to access capital from the DeFi ecosystem while providing users with an opportunity to earn returns on their investments.

Institutions are required to report the returns of their funds or initiatives, allowing pool providers to earn a share of the profits. This transparent reporting mechanism ensures that users can make informed decisions about their investments and track the performance of their assets within the MultiChainz ecosystem.

Cross-Chain RWA Lending

The MultiChainz Protocol is designed to support multiple blockchain networks, enabling users to seamlessly lend and borrow tokenized real-world assets across different chains. This cross-chain compatibility ensures low costs for every user, whether institutional or retail, such that they can opt to transact and lend through the chain that benefits them the most. This infrastructure sets up the DeFi stage for mass scale lending as not only users of the platform will lend and borrow on the asset of their choice, but also they have a wide range of interconnected chains at their service for more transaction fees’ efficiency.

Technical Architecture for Tokenized RWA lending:

To enable RWA lending, MultichainZ incorporates smart contracts, oracles, identity verification (KYC) , and integration with external systems:

  1. Smart Contracts Layer:

  • Asset Tokenization: Smart contracts are deployed on the underlying blockchain network to handle the tokenization process. These contracts represent real-world assets as digital tokens, ensuring transparency, ownership, and transferability. Asset tokenization involves converting physical assets, such as real estate, into digital tokens that can be traded and used as collateral.

  • Lending Contracts: Smart contracts govern the lending process, including loan origination, repayment terms, and collateral management. These contracts handle the interaction between borrowers, lenders, and the RWA tokens, enforcing loan agreements and facilitating automated processes.

  • Loan Agreement Management: Smart contracts store and manage loan agreements, including terms, repayment schedules, and interest rates. They ensure the immutability, transparency, and execution of loan agreements throughout the lending process.

  1. Oracles and External Data Sources:

  • Asset Valuation Oracles: The architecture incorporates decentralized oracles or integrates with trusted external data sources to provide real-time and accurate asset valuations. These oracles fetch data from reliable sources to determine the value of the underlying RWA tokens and assess collateralization ratios.

  • Credit Scoring and Risk Assessment: Integration with external credit scoring and risk assessment systems allows for evaluation of borrowers' creditworthiness. This integration helps determine loan eligibility, interest rates, and loan terms based on borrowers' financial history and risk profiles.

  1. Identity Verification and KYC:

  • Identity Verification: Integration with identity verification services enables Know Your Customer (KYC) processes for borrowers and lenders. This ensures compliance with regulations and reduces the risk of fraudulent activities.

  • KYC Data Management: The architecture securely manages and stores KYC data, ensuring data privacy and adherence to relevant regulations. Access controls and encryption mechanisms are implemented to protect sensitive user information.

  1. Integration with External Systems:

  • Payment Gateways: Integration with payment gateways allows borrowers to make loan repayments in traditional fiat currencies or cryptocurrencies. These gateways facilitate seamless transactions between borrowers, lenders, and the MultichainZ platform.

  • External Asset Management Systems: Integration with external asset management systems allows for tracking and verification of the underlying real-world assets tied to the tokenized RWA tokens. This integration ensures transparency and mitigates risks associated with asset ownership and valuation.

  1. User Interfaces:

  • Web/Mobile Applications: User interfaces are developed as web or mobile applications, providing borrowers and lenders with intuitive platforms to interact with the tokenized RWA lending process. These interfaces offer functionalities such as loan application, collateral submission, loan management, repayment tracking, and access to account information.

  • Wallet Integration: Integration with blockchain wallets allows users to connect their wallets to the MultichainZ platform securely. This enables easy access to RWA tokens, collateral, and borrowed funds, as well as transaction signing for interactions with smart contracts.

MultichainZ provides a secure and efficient platform for tokenized RWA lending. This architecture ensures transparency, automation, and compliance with regulatory requirements, enabling borrowers and lenders to participate in decentralized lending with Real-World Assets as collateral.
