About the app
Mercuryo provides the app experience: checkout, fiat payment methods, country availability, identity checks, token support, and order status.
Mercuryo uses direct payment details such as token, network, amount, and destination address. Arca is the wallet review layer; check the token, network, amount, and destination before you approve or send.
- Mercuryo handles its own account, product, pricing, availability, and support.
- Arca helps with the wallet step so you can review connection, payment, or signing requests before continuing.
How Mercuryo works with Arca
Mercuryo provides fiat-to-crypto and crypto-to-fiat checkout flows in supported regions. Mercuryo controls supported countries, payment methods, identity verification, fees, and asset availability. Where Mercuryo supports USDC on a network that matches Arca, you can use your Arca address as the receiving wallet and confirm the token and network before continuing.

Frequently asked questions

No. Mercuryo is a separate app with its own product, account, and support. Arca is a non-custodial wallet for digital dollars. They only work together at the wallet step you approve.
Which tokens can I use to pay Mercuryo?
Mercuryo accepts USDC on Ethereum, Arbitrum, Polygon, Solana, Stellar, Base, Near, Avalanche, BNB Chain and Optimism. Always match what the Mercuryo checkout shows before you send from Arca.
How do I pay Mercuryo with Arca?
Open Mercuryo and copy the destination address, token, network, and amount. In Arca, tap Send, choose Send to a wallet, and enter the same details. Review everything on the confirmation screen, then send.
What if I send to the wrong network or address?
Always match the token, network, and address that the app shows before you send. Payments sent to the wrong place are usually difficult to recover, which is why Arca shows a full review screen and a clear amount before you confirm.
