Question 1

How long does USDC take to bridge from Sonic to Ethereum?

Accepted Answer

The configured Standard attestation estimate is ~8 seconds. The Fast estimate, when available, is ~8 seconds. These describe source attestation, not guaranteed end-to-end delivery. The destination claim on Ethereum, network congestion and wallet approval add time.

Question 2

How many confirmations are needed on Sonic?

Accepted Answer

The app uses 1 source confirmations for Standard and 1 for Fast. These are source-network requirements for Circle's attestation; they are separate from the transaction that mints USDC on Ethereum.

Question 3

Can I use Fast for Sonic to Ethereum?

Accepted Answer

The app supports Fast transfers from Sonic. Live allowance, pricing and network conditions can affect availability; review the selector and quote before confirming.

Question 4

Which wallets and gas tokens do I need?

Accepted Answer

Use a compatible EVM wallet holding native USDC on Sonic and S for the source transaction. The recipient must be a compatible EVM address on Ethereum. To claim yourself, connect the destination wallet and keep ETH there for destination gas.

Question 5

What fees apply to this route?

Accepted Answer

Budget for source gas in S on Sonic and destination claim gas in ETH on Ethereum. Fast can also include Circle's Fast fee and an application fee deducted from USDC. Review the live fee breakdown and received amount before approving; gas is separate.

Question 6

Will I receive native USDC on Ethereum?

Accepted Answer

Yes. CCTP burns native USDC on Sonic and mints native USDC on Ethereum. It does not send a wrapped representation. Select native USDC on the source network rather than a bridged token with a similar name.

Question 7

What if my Sonic to Ethereum transfer is pending?

Accepted Answer

Use Find transfer with Sonic as the source and your source transaction hash. A transfer may be waiting for source confirmations, Circle's attestation, or a claim on Ethereum. Once attestation is ready, connect the destination wallet to continue an outstanding claim.
