Swap ETH from BNB Chain to USDC on Arbitrum One

Swap ETH from BNB Chain to USDC on Arbitrum One. You send Binance-Peg ETH on BNB Chain and you receive Circle's native USDC on Arbitrum One, not on Nova.

The peg is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. You approve it. BscScan shows it on chain id 56. It is not BNB and not native ETH. Gas is BNB, blocks about 3 seconds. Native USDC on Arbitrum One is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. Match it on Arbiscan, chain id 42161. That is not bridged USDC.e. ETH pays gas there. USDC does not, and the ARB token does not.

ETH leaves BNB Chain. USDC is what can arrive on Arbitrum One.

The peg wears an ETH label and still needs BNB

Wallets call 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 ETH. The fee coin is BNB. This page spends the peg only. If you hold BNB and no peg, the approval finds nothing. Native ETH already on Arbitrum is not an input either. Keep BNB or chain id 56 never broadcasts the approval.

Native USDC on Arbiscan, not the bridged copy

0xaf88d065e77c8cC2239327C5EDb3A432268e5831 is Circle's native USDC. USDC.e shares the ticker and fails the address test. Nova will not show this One balance. Six decimals look small next to the 18-decimal peg. Use the quote. Then hold ETH on chain id 42161, because the USDC cannot pay the fee.

BNB, ARB, and Tether are different jobs

Spending BNB is another page. Receiving the ARB token, WETH, or Tether is another page. This one is peg in, native USDC out. Arbitrum means One. If you did not need chain id 42161, trade on BNB Chain. The quote does not lock the USDC.

Read the USDC floor, then plan the ETH

The approval costs BNB and does not freeze the quote. Read the minimum USDC again when you sign the swap. A 3 second block is only BNB Chain. It is not a promise that Arbiscan shows the token. Sign on chain id 56. Ignore a destination pasted from a message. Keep the wallet on One.

Frequently asked questions

What is the best way to swap ETH from BNB Chain to USDC on Arbitrum One?

The peg is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. You approve it. XAUConnect compares live routes and lets your own wallet sign.

Is BNB Chain ETH the same coin as Arbitrum gas?

No. The peg is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 on BscScan. Gas on Arbitrum One is native ETH, chain id 42161, and this page does not pay it. It pays native USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbiscan. You need BNB to send and ETH after arrival. Nova is the wrong chain.

What if the USDC on Arbitrum is a different contract?

Then it is not this payout. Bridged USDC.e can share the ticker. Match 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbiscan. The source peg is only 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. If a pool wants the bridged copy, this route is the wrong tool. Check the full address before you send it on.

Why can I not transfer the USDC once it appears?

The wallet is missing ETH. Native USDC does not pay gas on chain id 42161, and the ARB token does not either. Arbiscan can show the token anyway. BNB left on BNB Chain cannot pay that fee. Add ETH, then the transfer can be signed.
