FilDA is the first HECO-based cross-chain lending DeFi project which provides users with deposit, lending and liquid mining services. It now supports lending for 20 kinds of assets, including HUSD and HBTC. Interest and FilDA can be obtained by depositing digital assets, and FilDA can be earned by borrowing digital assets. Users can also deposit FilDA single currency in DAO and participate in community governance to get FilDA incentives. Divided into Loan Agreement, Pledge Agreement and DAO Governance Agreement, FilDA runs automatically on the chain based on smart contracts, providing a low-cost and high-efficiency asset conversion platform for the crypto world. In the future, it will rely on cross-chain technology to expand more crypto assets and enable a wider range of asset flows and conversions.
