WalletConnect Launches Single-Integration Crypto Checkout for Merchants

WalletConnect has launched a single-integration crypto checkout service that lets merchants accept stablecoins and other digital assets without rebuilding payment flows for each chain. The general-availability release, confirmed in the company's announcement and documentation, supports assets across major networks and pushes fiat settlement, compliance and monitoring onto licensed partners.

What can merchants actually accept?

The supported-asset list is broad. USDC works on Ethereum, Base, Arbitrum, Solana and Stellar, among other networks. USDT is available on Ethereum, Polygon, Solana and Tron. EURC, ETH and SOL round out the core list. Fiat settlement exists only for selected token-and-network combinations, depending on which partner handles the conversion.

The service separates what a customer spends from what a merchant receives. Payments can involve token swaps or bridging between blockchains before settlement, according to WalletConnect's documentation.

Wallet coverage is the other half of the pitch. More than 700 WalletConnect-compatible wallets can connect, subject to each wallet's chain support. That figure is the company's own, but it reflects the network effect WalletConnect has built as a wallet-connection standard.

Direct exchange-account payments run on a separate mechanism. Binance Pay is live today. Coinbase, OKX and other integrations are marked coming soon. Merchants must onboard with each exchange individually, and the exchange handles compliance while settling funds into the merchant's own exchange account.

How does fiat settlement work?

WalletConnect does not hold the fiat rails itself. MoonPay is a named settlement partner, tied to the earlier Ingenico arrangement reported by The Defiant in April. MoonPay said its Virtual Accounts, powered by Iron, would convert stablecoin proceeds at Ingenico terminals into fiat and deliver settlement over banking rails. Ingenico announced its WalletConnect Pay integration for Android payment terminals in January.

WalletConnect's fiat coverage page lists dollars, euros and pounds for settlement.

Businesses without merchant-dashboard access must contact sales to get started. Payment providers can use a hosted checkout or build their own interface, though access to the software toolkit for the latter requires approval — a gating choice that signals WalletConnect wants control over who builds on the rails.

What about compliance?

For Travel Rule data capture, WalletConnect collects a user's full legal name, date of birth and place of birth once. It then captures wallet and IP addresses per transaction. Pre-execution screening checks U.S., UK and EU sanctions lists, the company says.

The limits are explicit. These controls do not include full retail-buyer identity verification or ongoing transaction monitoring. Those obligations remain with licensed participants in the chain — a deliberate division of labor that keeps WalletConnect on the infrastructure side of the regulatory line.

Who else is building this?

WalletConnect is not alone in connecting stablecoins to conventional merchant payments. Coinbase said in September that its Spring by Citi collaboration enables stablecoin checkout, with Coinbase converting to fiat and Citi settling as bank of record. Shift4's platform, launched in December 2025, takes the opposite direction: it gives merchants the option of receiving settlement in stablecoins rather than a bank transfer.

So what does this change for merchants? It collapses a multi-chain acceptance problem into one integration, while pushing the regulated work — identity checks, fiat conversion, monitoring — onto partners that already hold licenses. With Binance Pay live and Coinbase and OKX queued behind an approval process, the roadmap for the exchange-rail side of the service is the piece to watch through the coming quarters.
