DeFi Yield Optimizer

An autonomous yield farming bot that continuously monitors DeFi lending and liquidity protocols, identifies the highest-yielding opportunities, and automatically moves your capital to maximise returns — with auto-compounding built in.

What's Included — Full Source Code:

• Complete TypeScript/Solidity source code
• Pre-configured for Ethereum, Arbitrum, Polygon, Base, and Optimism
• Smart contract vault for on-chain automation
• Docker deployment with monitoring

Core Features:

• Multi-protocol scanning — monitors APY across Aave V3, Compound V3, Curve, Convex, Yearn, Lido, Rocket Pool, Morpho, and more
• Auto-rebalancing — moves funds to the highest-yielding protocol when the spread exceeds your threshold (default: 2% APY difference)
• Auto-compounding — harvests yield rewards and reinvests at configurable intervals (default: every 4 hours)
• Gas optimization — batches transactions, uses EIP-1559 priority fees, and only rebalances when the yield improvement exceeds gas costs
• Multi-chain support — deploys across Ethereum, Arbitrum, Polygon, Base, and Optimism from a single dashboard
• Impermanent loss protection — for LP positions, monitors IL and exits when losses exceed threshold

Risk Management:

• Protocol risk scoring — weights allocation toward battle-tested protocols
• Smart contract audit status check — flags unaudited protocols
• Maximum allocation per protocol (default: 40%)
• TVL monitoring — avoids protocols with declining TVL
• Depeg detection for stablecoins — exits if peg deviates beyond 0.5%
• Emergency withdrawal — one-click exit from all positions

Dashboard:

• Portfolio overview with current allocations and APY per position
• Historical yield tracking with charts
• Protocol comparison table
• Gas cost vs. yield improvement analysis
• Rebalance history with transaction links

Tech Stack:

• TypeScript + ethers.js
• Solidity smart contracts (ERC-4626 vaults)
• Next.js dashboard
• Hardhat for testing and deployment

Self-hosted. No platform fees. You keep 100% of your yield.
