Question 1

How long does USDC take to bridge from Injective to Arbitrum?

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 Arbitrum, network congestion and wallet approval add time.

Question 2

How many confirmations are needed on Injective?

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 Arbitrum.

Question 3

Can I use Fast for Injective to Arbitrum?

Accepted Answer

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

Accepted Answer

Yes. CCTP burns native USDC on Injective and mints native USDC on Arbitrum. 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 Injective to Arbitrum transfer is pending?

Accepted Answer

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