DeFi lending rates are volatile and there’s no native way to hedge them. In traditional finance, interest rate swaps are a $500T+ market. In DeFi, this market barely exists. Cascade Finance brings institutional-grade interest rate derivatives to Flow EVM through three composable protocols working together: • Lending Pool – Supply and borrow with dynamic rates (inspired by Compound V3 architecture) • DEX – Constant product AMM for token swaps (inspired by Uniswap V2 architecture) • IRS Protocol – Trade fixed vs floating interest rates as ERC-721 position NFTs What’s Deployed • 14 smart contracts on Flow EVM Testnet • 326 passing tests (unit, fuzz, invariant) • Full Next.js frontend with RainbowKit wallet integration • Up to 20x leverage on rate positions Why Flow • Sub-cent gas fees with hourly settlements under $0.01 • ~1 second finality, positions confirm instantly • No MEV, fair execution for rate traders GitHub: https://github.com/Leihyn/cascade-finance Network: Flow EVM Testnet (Chain ID 545) Stack: Solidity 0.8.24, Foundry, Next.js 14, wagmi v2 Built for Flow GrantDAO Round 2. #DeFi #Flow #InterestRateSwaps #Derivatives #Solidity #SmartContracts #FlowEVM #Web3
