Features
Everything you need to
accept crypto payments
Built for Arc, works everywhere. From a single payment button to a full payment infrastructure.
Gasless Payments
Customers sign a message — no transaction, no gas, no ETH needed. EIP-3009 authorization settles via the paymaster.
Multi-Chain CCTP
Accept USDC from Ethereum, Base, Polygon, Arbitrum, Avalanche, or Optimism. Circle CCTP bridges funds to Arc in ~20 seconds.
Web Component
Drop <meridian-pay-button> into any site. Shadow DOM isolation, 3 themes, custom events. ~6 KB, zero dependencies.
Instant Refunds
Full or partial refunds on-chain. The merchant signs, the relayer executes — gasless for everyone. 180-day window.
PDF Invoices
Auto-generated after every payment. Sequential numbering (MER-2026-00001), full breakdown, download from dashboard.
Email Receipts
Branded receipt to the customer, payment notification to the merchant. Automatic on every payment and refund.
Webhooks
Real-time events for payment.completed, refund.completed, and more. HMAC-SHA256 signed, 3-retry delivery.
Merchant Dashboard
Payments, refunds, invoices, API keys, webhooks, volume stats — all in a dark-mode portal. Login with your secret key.
Non-Custodial
Merchants keep their keys. USDC settles directly to your wallet. The relayer can only execute what you authorize.
