Question 1

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

Accepted Answer

There is no published timing estimate in the app for this source network. 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 Cronos?

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 Cronos to Optimism?

Accepted Answer

The app supports Fast transfers from Cronos. 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 Cronos and CRO 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 CRO on Cronos 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 Cronos 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 Cronos to Optimism transfer is pending?

Accepted Answer

Use Find transfer with Cronos 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.
