1inch Fusion+ Extension Ethereum and NEAR/Aptos chains using Hash Time-Locked Contracts (HTLC).
Demo
About
A cross-chain swap extension for 1inch Fusion+ that enables bidirectional swaps between Ethereum and NEAR/Aptos chains using Hash Time-Locked Contracts (HTLC). Features: ✅ Bidirectional swaps: ETH ↔ NEAR and ETH ↔ Aptos ✅ Hash Time-Locked Contracts (HTLC): With proper hashlock and timelock functionality ✅ 1inch Escrow Factory integration: On Ethereum side ✅ Custom escrow contracts: For NEAR and Aptos ✅ Cross-chain orchestration layer ✅ Mainnet and testnet support
