Swap USDC from Arbitrum One to BNB on BNB Chain

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

Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 is the spend on Arbitrum One. Check Arbiscan. Chain id 42161, not Nova. The fee there is ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on that chain. The same sentinel on the destination means native BNB, the gas coin of BNB Chain, chain id 56. BscScan shows it as an account balance, not as a BEP-20 supply. Blocks are about 3 seconds. That is not a fill time.

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

The sentinel changes meaning with the chain

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is not one token. On Arbitrum One it is ETH, which you must already hold for fees. On BNB Chain it is BNB, which this route can credit. If you copy the hex into a token search on BscScan, you will not find a normal BEP-20. Watch the account's BNB balance instead. Binance-Peg ETH at 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 is a different asset and is not this output.

Useful when the next action needs gas

People take this route when a BNB Chain wallet has tokens but cannot move them. Native BNB is what pays those fees. It is a volatile coin against Circle USDC, so the minimum matters. Do not assume a dollar of USDC becomes a fixed slice of BNB. Refresh the quote if it expires. Six-decimal USDC in, eighteen-decimal BNB out, and the human amounts on the quote are the ones to read.

Source fee is still ETH

Arriving BNB does not pay the Arbitrum transaction that starts the route. Keep ETH on chain id 42161. USDC may need an approval, and that approval needs gas too. How to bridge assets between chains keeps those two payments straight: ETH where you sign, BNB where you land. Nova cannot supply the source fee.

Wrong if you wanted a dollar token on BSC

This page will not deliver BSC USDT at 0x55d398326f99059fF775485246999027B3197955 or Binance-Peg USDC at 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. It will not deliver pegged ETH. It is wrong if you wanted Circle USDC to remain a stablecoin, wrong if you hold USDC.e, and wrong if you thought BNB on this page was an ERC-20 you must approve on the destination.

Frequently asked questions

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

Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 is the spend on Arbitrum One. Check Arbiscan.

Is native BNB the same as Binance-Peg ETH?

No. Native BNB is the gas coin, marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 56. Binance-Peg ETH is the BEP-20 at 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. This route can credit BNB, not that peg. You spend Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. Check BscScan for the BNB balance, not for a token contract at the sentinel.

Do I approve BNB on BNB Chain to receive it?

No. Native BNB is not an ERC-20 you approve in order to receive. Any approval happens on Arbitrum One for Circle USDC, paid in ETH. Chain id 42161, not Nova. Arbiscan should show 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. About 3 seconds is the typical BNB Chain block, not a schedule for the credit.

Why might the BNB amount differ from the dollars I typed?

BNB floats against the dollar. Circle USDC does not. Fees and price sit between them. Use the minimum on the quote, and replace the quote if it expires. Decimals differ too: USDC has six, BNB has eighteen. Compare whole tokens. This page is the wrong one if you needed a stablecoin to arrive instead of gas.
