Description
Mach Exchange is a cross-chain swap protocol using an intents-based architecture with optimistic escrow. Users submit on-chain orders specifying a source asset and chain and a desired output asset and destination chain. Market makers compete to fill these orders by delivering the requested asset directly on the destination chain. A challenge mechanism powered by LayerZero seizes solver collateral when commitments are not honored, enabling single-block settlement under normal conditions. The protocol does not use liquidity pools and requires no intermediary tokens.
