> Build apps anyone can fund.

Chainrails is a payment infrastructure protocol for developers. It lets applications accept deposits from any blockchain, token, or fiat currency through a single integration.

Chainrails is a payment infrastructure protocol that lets developers accept value from multiple blockchains and fiat sources through a single integration. Payers can transact using any supported chain, token, or fiat method, while businesses receive funds in their preferred chain, token, or bank account. It targets application builders who need multi-chain payment acceptance without managing bridges, liquidity, or separate integrations for each network.

The protocol addresses the complexity of multi-chain commerce by abstracting bridging, swapping, ramping, and settlement into a single layer. Developers integrate through an SDK, API, or smart contract interface, and incoming payments are automatically 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.

Core offerings include deposit and withdrawal processing, shareable payment links, and a dashboard for monitoring transaction volume and performance. A liquidity orchestration feature for routing value between fiat and stablecoin rails is in development. The protocol is used by application developers and merchants who need to accept and disburse funds across a range of blockchains and fiat currencies without building custom infrastructure for each one.

## Products

- [ChainRails](https://thegrid.id/profiles/chainrails): ChainRails is a merchant payment gateway that lets businesses accept cryptocurrency and fiat payments from any supported blockchain, token, or currency through a single integration. It processes transactions with an intent-based architecture that escrows funds on-chain, automatically routes and swaps or bridges them, and settles to the recipient's preferred chain, token, or bank account. Businesses integrate through an embeddable payment modal, direct API and SDK calls, or contract-level integration, and can generate shareable payment links, manage deposits and withdrawals, and sponsor network fees for end users through a paymaster feature. A dashboard provides visibility into volume, revenue, and API configuration. Fiat conversion and identity verification are handled through integrated ramp and KYC flows.
