# ChainRails

> Build apps anyone can fund.

Chainrails is a payment infrastructure provider for developers. It lets applications accept deposits in crypto or fiat through one integration and receive funds in their preferred form.

Chainrails is a payment infrastructure provider that lets developers accept crypto and fiat payments through a single integration. Payers fund an app with crypto on any supported blockchain, cards, bank transfers, or local fiat rails, while businesses receive funds in their preferred chain, token, or bank account. It targets application builders who want multi-chain funding without managing bridges, liquidity, or separate payment processors.

The platform handles provider selection, ramps, swaps, bridging, routing, and settlement beneath one API. Developers integrate through an SDK, an API, or smart contract calls, and incoming payments are routed, converted, and settled to the destination the business specifies. This removes the need to maintain custody infrastructure or manually manage liquidity across networks and currencies.

Offerings include deposit and withdrawal processing, shareable payment links, a paymaster that sponsors protocol fees for users, and a dashboard for volume, revenue, and API configuration. Wallets, games, exchanges, and other applications that let users fund accounts use it.
