Accept crypto.
Settle in fiat.
PurpleRail is the crypto payments layer for PSPs and financial institutions. Your merchants' customers pay in USDC, USDT, ETH or Bitcoin; your merchants receive euros, pounds or dollars. Every payment is screened, converted and reconciled for you.
One API · hosted checkout · iOS and Android apps · 20 settlement currencies


Crypto acceptance without building a crypto company
Wallets, blockchains, confirmations, AML screening, custody, conversion, off-ramping and reconciliation — handled behind one integration.
One API, hosted checkout
Create a payment, send the customer to the checkout, get signed webhooks. Or use payment links and invoices with no integration at all.
Compliance built in
Every deposit screened. Sanctioned funds frozen automatically. Review queues, two-person approvals and a full audit trail.
Fiat where you need it
Settle per payment or in a daily batch, to each merchant or to your own account, with a settlement report for every batch.
Funds never with us
A licensed financial institution owns the custody workspace and its policies. PurpleRail can only move funds to destinations that institution has approved.
Every cent reconciled
A double-entry ledger the database itself keeps balanced, reconciled daily against custody and bank balances.
In person, too
Merchants take payments at the counter from the iOS and Android app: type an amount, the customer scans and pays.
A checkout people trust on the first try
Clear amounts, a locked price, a unique address and QR code for every order, and plain-language status from "detected" to "complete". Partial payments, late payments and the wrong token are caught and explained.
- Price locked for 15 minutes, network fee shown up front
- Works with any wallet: scan, copy or connect
- Desktop and mobile, accessible, fast

Every payment, explained
A full timeline for each payment: risk evidence, conversion to stablecoin and fiat, payout and every ledger entry. Exceptions go to a review queue; sensitive actions can require a second approver.
- Role-based access with two-factor sign-in
- Daily reconciliation dashboard
- Per-institution limits and volume caps
