Project Description
Problem:
- Inactive liquidity on DEXes does not generate yield for the liquidity providers.
- Similarly, the rewards on lending protocols are in idle state without generating profit.
- Too complex UI & Bad UX.
Solutions:
- Reinvest the inactive assets by depositing on lending protocols using hooks.
- Maximize yields with compound rewards.
- 1-click investment.
Features:
- Lending pool fallback for DEX LP providers
- Uniswap & PancakeSwap v4 hooks are used to trigger entry and exits from AAVE.
- Buffer ticks to prevent excessive movement of funds.
- Safe account abstraction with ERC7579 and ERC4337
- Safe v1.4.1 with fallback handler to handle 4337 and 7579 methods.
- 1-click UX throughout the application.
- ERC7579 module executes claiming rewards on interval.
How it's Made
- Foundry made writing tests, deployments and contracts possible in solidity
- Used Dynamic to generate hosted embedded wallets, Pimlico to sponsor transactions
- Hacking Permissionless.js to figure out why only the older 0.1.36 versions worked with deployment of Safe and found an undocumented parameter name changed.
- Older version of permissionless.js did not work with batch transactions for 7579 wallets
- Used Rhinestone Safe7579 implementation as a fallback handler, this enabled Safe to be both 4337 and 7579 to be compatible
- Viem to encode complex structs and calldata to provideLiquidity
