Welcome to Volr

Volr is a stablecoin checkout solution for accepting crypto payments. Create a checkout via API, share a payment link, and get notified when payment is confirmed on-chain.

How It Works​

Why Stablecoin Checkout?​

  • Global reach — Accept payments from 100+ countries, no merchant account required
  • Low fees — ~0.5% vs 2.9% + $0.30 per card transaction
  • No chargebacks — Blockchain transactions are final
  • Instant settlement — Funds arrive in your wallet after on-chain confirmation
  • Fiat pricing — Price in USD/KRW, auto-convert to token amounts

Integration Options​

Server-side TypeScript SDK for creating and managing checkouts programmatically.

npm install @volr/checkout-sdk
import { VolrCheckout } from '@volr/checkout-sdk';

const volr = new VolrCheckout({ serverKey: process.env.VOLR_SERVER_KEY! });

const checkout = await volr.create({
  chainId: 8453,
  tokenAddress: '0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913',
  merchantAddress: '0xYOUR_WALLET',
  fiatAmount: '25.00',
  fiatCurrency: 'USD',
  itemName: 'Premium Plan',
});

Checkout API​

Direct HTTP API for any language or platform. Same endpoints, full control.

curl -X POST https://api.volr.io/v1/checkouts \
  -H "X-API-Key: volr_server_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"chainId": 8453, "tokenAddress": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", "merchantAddress": "0xYOUR_WALLET", "fiatAmount": "25.00", "fiatCurrency": "USD"}'
