Question 1

How long does USDC take to bridge from Base to XDC?

Accepted Answer

The configured Standard attestation estimate is ~13 to 19 minutes. The Fast estimate, when available, is ~8 seconds. These describe source attestation, not guaranteed end-to-end delivery. The destination claim on XDC, network congestion and wallet approval add time.

Question 2

How many confirmations are needed on Base?

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 XDC.

Question 3

Can I use Fast for Base to XDC?

Accepted Answer

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

Question 5

What fees apply to this route?

Accepted Answer

Budget for source gas in ETH on Base and destination claim gas in XDC on XDC. 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 XDC?

Accepted Answer

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

Accepted Answer

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