Key Features

Everything you need to accept stablecoin payments, built into one component.

Accept payments from Ethereum, Base, Polygon, Arbitrum, Avalanche, Optimism, Linea, Unichain, and Sonic. One widget, all chains.

Set a fixed price for products or let customers enter any amount. Both modes supported with a single configuration attribute.

Works with MetaMask, Coinbase Wallet, Rainbow, WalletConnect, and 300+ wallets through RainbowKit integration.

Live transaction tracking with instant confirmations. Customers and merchants see payment status updates in real time via SSE.

Four simple steps from integration to receiving payments.

Include a single script tag on your page with your merchant ID. The widget loads asynchronously and does not block your site.

A payment modal appears with chain selection and amount confirmation. Clean, professional UI that matches any site design.

The customer connects their wallet and approves the transaction. Cross-chain payments are bridged automatically via Circle CCTP.

Payment is verified on-chain and confirmed in real time. Funds arrive directly in your merchant wallet. No intermediaries.

Choose the method that fits your workflow.

Drop a single script tag into any HTML page. No framework required. Works with WordPress, Shopify, static sites, and more.

Create checkout sessions programmatically via the REST API. Full control over amounts, metadata, and redirect URLs.

Redirect customers to a Fivo-hosted checkout page. No frontend code needed. Perfect for invoices and email links.

Use the open-source widget as a starting point. Fork it, customize the UI, add your own logic. Full flexibility.

Integrate the Fivo widget in minutes and receive stablecoin payments from any chain.
