Welcome to our GitHub repository for the hackathon project aiming to become a GHO facilitator. In this project, we focus on enabling cross-chain lending of whitelisted NFTs to mint GHO, a stablecoin created by the Aave protocol and collateralized by various assets. To achieve this, we leverage Chainlink's Cross-Chain Interoperability Protocol for seamless communication between different blockchain networks.
Before you begin, ensure you have the following prerequisites installed:
-
Clone the repository:
git clone https://github.com/Hendobox/GHO-Facilitator-Hackathon.git cd gho-cross-chain-lending -
Install dependencies:
npm install
Describes the project structure briefly. Highlight important directories and files.
- Cross-chain lending of whitelisted NFTs.
- Minting GHO stablecoin on the desired blockchain.
- Secondary Investment to maximize yield and manage risk
- Open liquidation for liquidators to participate.
Our project's architecture is designed to facilitate cross-chain lending of whitelisted NFTs and minting GHO stablecoins using Aave protocol, with the integration of Chainlink's Cross Chain Interoperability Protocol (CCIP). Below are the key components and their interactions:
-
Mock NFT
- Simulates a whitelisted NFT contract for testing purposes.
-
Mock ERC20 token(s) - (USDC and/or GHO)
- Mock implementation of ERC20 tokens, such as USDC and GHO, used for collateralization and minting.
-
Lending Protocol
- Main contract responsible for managing the borrowing, repayment, and claiming processes.
Our project seamlessly integrates with the Aave protocol for collateralization, ensuring a secure and reliable lending process. The integration involves utilizing Aave's lending and borrowing functionalities to lock collateral and mint GHO stablecoins.
Our integration with Savvy DeFi introduces a unique dimension to our project, combining NFT collateralization with decentralized finance opportunities. Users lock their NFTs in our vault as collateral, enabling them to generate the maximum possible GHO within the collateral ratio. As borrowers are typically over-collateralized, we leverage this excess collateral to provide an avenue for borrowing svUSD from Savvy DeFi. This innovative approach not only enhances risk management for borrowers but also introduces a revenue model through incentives. By connecting our project with Savvy DeFi, we aim to create a symbiotic relationship that empowers users with additional financial opportunities while maintaining the security and integrity of our cross-chain NFT lending platform.
Our integration with Chainlink forms a crucial part of our project, enhancing cross-chain interoperability and ensuring seamless communication between different blockchain networks. Leveraging Chainlink's Cross Chain Interoperability Protocol (CCIP), our Protocol Contract facilitates the secure and transparent movement of data and assets across supported chains. This integration enables borrowers to initiate transactions from any chain, ensuring a decentralized and inclusive lending experience. Chainlink's robust infrastructure enhances the overall reliability of our cross-chain NFT lending solution, providing users with a trustworthy and scalable platform.
