Automatic stablecoin swaps
Payment links settle in the token selected by the creator, while payers can use USDC, USDT or USDm. If the payer token differs from the requested token, Paygrid quotes and executes a Mento-routed swap so the recipient still receives the original settlement token.
| Token | Decimals | Role |
|---|---|---|
| USDC | 6 | Supported payer and settlement token |
| USDT | 6 | Supported payer and settlement token |
| USDm | 18 | Supported payer and settlement token |
Agents can call quote_payment_request to inspect the route and pay_payment_request to prepare approval and payment transactions.
Mainnet swap proof
Paygrid has a live Celo Mainnet transaction proving the swap-enabled flow.

| Transaction | 0xef8a70228255479df5b42ad57aa708a14b108faff4725c0cbcb4e1a4439ce4d5 |
| Flow | USDT payer token to USDC settlement token |
| Router | PaygridRouterV2 |
| Swap route | Mento Router |
| Recipient settlement | USDC |
The transaction calls PaygridRouterV2, routes through Mento, emits SwapPayment and PaymentReceived, pays the recipient in USDC and marks the payment request as paid onchain.
