fusion swap

Problem Statement

FusionSwap enables secure, atomic swaps between multiple blockchain networks including Bitcoin, Ethereum, Tron, and TON. The protocol leverages hashlock and timelock mechanisms (HTLC) on both EVM and non-EVM chains, ensuring trustless and atomic settlement. Users can create intent-based orders on any supported chain, which are matched and executed via off-chain relayers and the 1inch Fusion+ resolver network. The system supports partial fills, competitive price discovery through Dutch auctions, and is designed to be extensible for additional chains and order types
