Homeward is a self-service migration protocol that lets Arbitrum Nova ETH holders move their ETH to Arbitrum One through the canonical bridge path without having to separately fund Ethereum L1 gas
Homeward is a self-service ETH migration protocol that simplifies the canonical Arbitrum Nova → Ethereum → Arbitrum One migration flow. Users authorize their migration once on Nova, including their destination wallet, maximum deductions, executor reward, and minimum delivery amount. A gas-advancing worker then coordinates the canonical withdrawal, Ethereum-side execution, and Arbitrum One retryable flow while the contracts enforce isolated job accounting and user-defined limits.
Homeward removes the need for users to separately manage Ethereum L1 gas and manually return to complete each stage of the canonical migration process.
<p>During the hackathon, we built the full Homeward stack from the ground up, including:</p><ul><li><p>Nova migration entry smart contract</p></li><li><p>Ethereum completion/router contract</p></li><li><p>Automated TypeScript execution worker</p></li><li><p>Arbitrum retryable-ticket monitoring</p></li><li><p>Web frontend for creating and tracking migrations</p></li><li><p>Self-service recovery CLI</p></li><li><p>Arbitrum Sepolia and Ethereum Sepolia deployments</p></li><li><p>Unit, fuzz, invariant and fork-simulation tests</p></li><li><p>CI/CD and Slither security analysis</p></li><li><p>Live testnet application and migration-tracking interface</p></li></ul><p>The architecture is focused specifically on native ETH migration using Arbitrum's canonical bridge infrastructure.</p>
<p>self funded.</p>
