Question 1

How long does USDC take to bridge from Ethereum to X Layer?

Accepted Answer

The configured Standard attestation estimate is ~13 to 19 minutes. The Fast estimate, when available, is ~20 seconds. These describe source attestation, not guaranteed end-to-end delivery. The destination claim on X Layer, network congestion and wallet approval add time.

Question 2

How many confirmations are needed on Ethereum?

Accepted Answer

The app uses 65 source confirmations for Standard and 2 for Fast. These are source-network requirements for Circle's attestation; they are separate from the transaction that mints USDC on X Layer.

Question 3

Can I use Fast for Ethereum to X Layer?

Accepted Answer

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

Question 5

What fees apply to this route?

Accepted Answer

Budget for source gas in ETH on Ethereum and destination claim gas in OKB on X Layer. 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 X Layer?

Accepted Answer

Yes. CCTP burns native USDC on Ethereum and mints native USDC on X Layer. 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 Ethereum to X Layer transfer is pending?

Accepted Answer

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