About the app
Spark provides the app experience: savings products, lending markets, borrowing, rates, supported assets, network details, and position status.
Spark 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.
- Spark 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 Spark works with Arca
Spark offers stablecoin-focused savings and lending products across supported deployments. Spark controls markets, supported assets, rates, collateral rules, and position status. Arca can be used to connect and review wallet actions such as approvals, deposits, withdrawals, and borrows. Confirm the selected market, network, token, and amount before approving.

Frequently asked questions
Is Spark part of Arca?
No. Spark 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 Spark?
Spark accepts USDC or USDT or PYUSD or USDS or ETH on Ethereum and Supported Spark deployments. Always match what the Spark checkout shows before you send from Arca.
How do I connect Arca to Spark?
On Spark, 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.
