Users generate signed intents specifying: target ENS domain names, maximum price parameters (renewal fee + gas fee + solver reward), renewal conditions (expiration threshold, gas price threshold).
- REST API endpoints for intent submission and validation
- Local mempool implementation for intent storage and management
- Continuous monitoring of: ENS domain expiration timestamps, Ethereum network gas prices, user token balances.
- Eliminates manual renewal tracking
- Reduces gas costs thanks to execution timing
- Improves UX through gasless intent submission
- Ensures ENS domains for individuals and important projects in web3 don't expire
User friendly UI with intent creation and management.
Deployed to local fork of Ethereum Sepolia.
Current flow:
- User signs action using
sign messageMetamask feature which should contain array of ENS names and a numeric value which represents reward for executing each action. - Backend solver submits tx on-chain.
- Contract verifies signatures and token balances.
- Auto-renew ENS names if conditions are met (
Xdays until expiry date, gas price at or belowY).
