OpenRampKitUnified deposits and withdrawals for any app

The RainbowKit for onramps and deposits. Users pay with a card, a bank transfer, an exchange or a local QR rail, and stablecoins land on any chain. One modal, a server you host, no platform fee.

Why OpenRampKit?

Get started

GitHub

This is the real OpenRampKit server and modal, running in your browser with mock providers. No account, no real money. Pick a country and a payment method, then press "Simulate payment".

Support for local payment rails

Pix, UPI, SEPA, ACH and national QR codes where providers support them, next to cards, Apple Pay, Google Pay and wallets.

Pathways, not vendors

A planner picks the best route at run time across 10 providers, for example a card or bank transfer to USDC on Base, then a bridge to Arbitrum. Every quote, fee and status is visible.

Onchain settlement

OpenRampSettlement settles each session once and can deposit into a vault in the same transaction. Live on Arbitrum Sepolia, Robinhood Chain Testnet and Tempo Testnet.

Any chain

USDC on Arbitrum, Base, Solana, Tempo and other chains. Withdrawals to a wallet or a bank account use the same kit.

Agent-ready

An MCP server lets an AI agent send a person a pay link, wait for the payment, then act. Guardrails cap destinations and amounts.

Works in any framework

One component for React, Vue, Svelte or plain HTML. Theme it to match your app.

Self-hosted

One server you run on Cloudflare Workers, Next.js, Node, Bun or Deno. Your keys, your data, MIT licence.

Plug in any provider

Each payment method or provider is an adapter. Add a new onramp, local rail or exchange with one adapter and a test kit, without forking.
