Stablecoins are no longer confined to DeFi dashboards and crypto-native apps. In the span of a single quarter, two major partnerships have brought stablecoin payments to physical retail at global scale — and the infrastructure behind them is something every fintech developer and crypto developer in the UK should understand. Ingenico has launched native stablecoin checkout across its 40 million Android POS terminals via WalletConnect Pay, whilst Paysafe has integrated MoonPay's stablecoin rails into its $167 billion-a-year payment platform. For payment developers, the message is clear: stablecoin acceptance at the point of sale is now production infrastructure, not a pilot programme.
How Stablecoin Checkout Works at Physical POS
The Ingenico-WalletConnect integration is the first to bring native stablecoin payments to physical retail terminals without requiring new hardware. Here is how the flow works from a payment developer's perspective:
- Customer initiates payment. At checkout, the customer selects stablecoin as their payment method. The Ingenico Android terminal displays a QR code or initiates a WalletConnect session.
- Wallet connection. The customer scans the QR code with any of 700+ compatible wallets connected through the WalletConnect protocol — serving over half a billion crypto users globally.
- Stablecoin transfer. The customer authorises the payment in their wallet. Supported stablecoins include USDC, EURC, and USDT across multiple blockchains.
- Fiat conversion and settlement. WalletConnect Pay handles the conversion from stablecoin to fiat currency. The merchant receives settlement in their local currency through their existing acquirer — no crypto touches the merchant's balance sheet.
The critical architectural insight is that WalletConnect Pay operates as a "messaging layer that sits alongside settlement." It abstracts blockchain complexity entirely from the merchant. As WalletConnect Pay CEO Jess Houlgrave put it: "The payments company and the merchant shouldn't even need to know about any of this stuff. They should just be able to serve this as an offering."
For Ingenico, this means the Digital Currency Application runs on existing Android terminals — no hardware swap, no new integration for acquirers beyond enabling the app. The potential reach is staggering: 40 million POS units across 120 countries.
Paysafe and MoonPay: Stablecoin Rails Inside a $167B Platform
The second major development is Paysafe's integration of MoonPay's crypto payment infrastructure, announced on 8 April 2026. Paysafe processed $167 billion in transactions in 2025 — this is not a niche crypto processor, but a mainstream payment platform serving e-commerce, financial services, retail, and iGaming.
