Question 1

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

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 Unichain, 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 Unichain.

Question 3

Can I use Fast for Ink to Unichain?

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 Unichain. 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 ETH on Ink and destination claim gas in ETH on Unichain. 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 Unichain?

Accepted Answer

Yes. CCTP burns native USDC on Ink and mints native USDC on Unichain. 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 Unichain 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 Unichain. Once attestation is ready, connect the destination wallet to continue an outstanding claim.
