Question 1

How long does USDC take to bridge from Codex Mainnet to Base?

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 Base, network congestion and wallet approval add time.

Question 2

How many confirmations are needed on Codex Mainnet?

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 Base.

Question 3

Can I use Fast for Codex Mainnet to Base?

Accepted Answer

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

Accepted Answer

Yes. CCTP burns native USDC on Codex Mainnet and mints native USDC on Base. 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 Codex Mainnet to Base transfer is pending?

Accepted Answer

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