Question 1

How long does USDC take to bridge from Avalanche to Optimism?

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 Optimism, network congestion and wallet approval add time.

Question 2

How many confirmations are needed on Avalanche?

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 Optimism.

Question 3

Can I use Fast for Avalanche to Optimism?

Accepted Answer

The app supports Fast transfers from Avalanche. 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 Avalanche and AVAX for the source transaction. The recipient must be a compatible EVM address on Optimism. 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 AVAX on Avalanche and destination claim gas in ETH on Optimism. 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 Optimism?

Accepted Answer

Yes. CCTP burns native USDC on Avalanche and mints native USDC on Optimism. 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 Avalanche to Optimism transfer is pending?

Accepted Answer

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