About the app
Euler provides the app experience: vault listings, earn products, lending markets, supported networks, rates, risk details, and position management.
Euler uses WalletConnect for wallet connection, approvals, or onchain actions. Arca is the wallet review layer; check the token, network, amount, and destination before you approve or send.
- Euler 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 Euler works with Arca
Euler provides modular lending markets, vaults, and earn products for supported assets across supported networks. Euler controls vault parameters, rates, risk details, and position management. Arca can be used as the wallet for connection, approval, deposit, withdrawal, and other signing steps. Review the vault, token, network, and amount before confirming any action.

Frequently asked questions
Is Euler part of Arca?
No. Euler 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 Euler?
Euler accepts USDC on Ethereum and EVM-compatible networks. Always match what the Euler checkout shows before you send from Arca.
How do I connect Arca to Euler?
On Euler, choose the connect option and pick WalletConnect. Scan the QR code with Arca, or tap the deep link to open Arca on the same phone. Arca shows a review screen before connecting so you can confirm the request came from you.
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.
