ZyloPay developer documentation

In-store USDC payments, driven from your systems.

Customers tap an Apple or Google Wallet pass at your terminal. The payment settles in USDC on Monad in under a second. The ZyloPay API lets your servers send payments to terminals, follow every payment, refund, and receive signed webhooks.
