Swap USDC from Arbitrum One to ETH on BNB Chain

Swap USDC from Arbitrum One to ETH on BNB Chain. Circle USDC leaves Arbitrum One and pegged ETH arrives on BNB Chain.

Spend Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbitrum One, chain id 42161, not Nova. Arbiscan confirms it. Gas there is native ETH. What BscScan should show on the way in is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8, Binance-Peg ETH, a BEP-20. It is not native ETH, not WETH on Ethereum, and not the gas sentinel. BNB Chain is chain id 56. Gas is BNB. Blocks are about 3 seconds and do not schedule the credit.

Diagram for Swap USDC from Arbitrum One to ETH on BNB Chain — USDC leaves Arbitrum One. ETH is what can arrive on BNB Chain.

Pegged ETH cannot pay BNB Chain fees

0x2170Ed0880ac9A755fd29B2688956BD959F933F8 is an ERC-20 style token on chain id 56. People call it ETH. The network calls the fee BNB. If you arrive with only this token, you still cannot send it until the wallet holds BNB. The sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE would have meant native BNB. This route deliberately does not use that marker. Do not unwrap it as if it were WETH9 on Ethereum.

Do not paste the Ethereum WETH address

Canonical WETH on Ethereum is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. It does not exist as the receive asset here. Arbitrum WETH is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 and is not what you sell either. You sell Circle USDC. BscScan's token page for 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 is the identity check. A ticker match against mainnet ETH is how funds get labeled and then stuck.

Dollar in, ether-linked token out

Circle USDC targets a dollar. Pegged ETH tracks ether, with the peg and pool risks of that BEP-20. The minimum can move. Refresh a stale quote. Six decimals on the USDC you spend are not the decimals of the BEP-20 you receive. How cross-chain bridges work is background for the chain change. It does not turn this BEP-20 into the gas coin of chain id 56.

Wrong page if you needed BNB or mainnet ETH

Choose another route if the wallet on BNB Chain needs native BNB. Choose another route if you wanted ETH on Ethereum, chain id 1. This credit lives on chain id 56 only. It is also the wrong page if you hold USDC.e rather than 0xaf88d065e77c8cC2239327C5EDb3A432268e5831, or if you wanted BSC USDT or Binance-Peg USDC instead of the ETH peg.

Frequently asked questions

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

Spend Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbitrum One, chain id 42161, not Nova. Arbiscan confirms it.

Is Binance-Peg ETH the same as native ETH?

No. Native ETH is the gas coin on Ethereum and on Arbitrum One. On this route the output is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8, a BEP-20 on BNB Chain. It does not pay gas. Gas there is BNB. Confirm the token on BscScan. Ethereum WETH at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 is a third, separate contract.

What do I spend, and on which explorer?

Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbitrum One. Arbiscan is the explorer, chain id 42161, not Nova. You need native ETH there for the fee. The pegged ETH token is only the receive side, on chain id 56. About 3 seconds is a BNB Chain block time, not a promise for when the BEP-20 appears.

Can I use this ETH peg to pay a BNB Chain swap?

Not as gas. You can sell the BEP-20 later if a pool lists it, but the transaction fee is BNB. If the account has no BNB, the pegged ETH sits until you add gas. This route does not include the sentinel that would have delivered native BNB. Fund BNB separately before you rely on the token.
