what's Chainrails?

Chainrails is a Web3 infrastructure protocol that addresses fragmentation across blockchains and tokens by providing a single SDK for developers to accept instant payments and deposits from any chain in any cryptocurrency or fiat. It eliminates the need for custom bridges, liquidity management, or multi-chain deployments, allowing apps to build on one chain while seamlessly accessing users and value from diverse ecosystems. Technically, Chainrails leverages intents and a paymaster system to sponsor bridging or swap fees, ensuring frictionless user experiences. It supports over 11 networks including Ethereum, Starknet, Base, Monad, Avalanche, Arbitrum, BSC, Polygon, Optimism, HyperEVM, and Lisk, with multiple tokens such as USDC, USDT, DAI, ETH, STRK, and more. An intent broadcaster enables direct cross-chain interactions from smart contracts, powering applications in DeFi, payments, and beyond.
