Meson Finance is a stablecoin cross-chain swap protocol based on HTLC atomic swaps. It enables peer-to-peer exchanges of stablecoins such as USDT and USDC across Ethereum, BNB Chain, Tron, Arbitrum, and other chains and L2s. Users can swap 1:1 directly without wrapped tokens or third-party custody. The protocol uses meta-transactions so liquidity providers pay gas fees, and users do not need native tokens. Developers can integrate via link, SDK, or API to add multi-chain stablecoin swapping to their apps.
