Question 1

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

Accepted Answer

The configured Standard attestation estimate is ~30 minutes. The Fast estimate, when available, is ~8 seconds. These describe source attestation, not guaranteed end-to-end delivery. The destination claim on Sonic, network congestion and wallet approval add time.

Question 2

How many confirmations are needed on Ink?

Accepted Answer

The app uses 65 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 Sonic.

Question 3

Can I use Fast for Ink to Sonic?

Accepted Answer

The app supports Fast transfers from Ink. 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 Ink and ETH for the source transaction. The recipient must be a compatible EVM address on Sonic. To claim yourself, connect the destination wallet and keep S there for destination gas.

Question 5

What fees apply to this route?

Accepted Answer

Budget for source gas in ETH on Ink and destination claim gas in S on Sonic. 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 Sonic?

Accepted Answer

Yes. CCTP burns native USDC on Ink and mints native USDC on Sonic. 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 Ink to Sonic transfer is pending?

Accepted Answer

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