Swap BNB from BNB Chain to USDC on Arbitrum One

Swap BNB from BNB Chain to USDC on Arbitrum One. You send native BNB on BNB Chain and you receive Circle's native USDC on Arbitrum One.

The source marker 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means BNB, the gas coin on chain id 56. No ERC-20 approval. BscScan shows a native send. Blocks are about 3 seconds. Leave extra BNB for the fee. Native USDC is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. Match it on Arbiscan, chain id 42161, not Nova. It is not USDC.e. You will need ETH to move it. ARB will not pay that fee.

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

BNB is both the asset and the fee

There is no token approval, but there is a fee. Selling every BNB stalls the transaction. The page will not sell the ETH peg and will not sell a stablecoin peg. If those are the balances you meant, this is the wrong route. The marker is the gas coin, not a contract you open on BscScan.

Circle's native contract, then an ETH gap

Arbiscan should show 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 and not a bridged USDC.e address. The USDC cannot pay gas on chain id 42161. ETH has to be there already. BNB does not arrive with the dollars. A wallet that only holds this USDC is stuck until ETH is added.

The peg and the ARB token are not this trade

The ETH listing on BNB Chain is a peg this page ignores. ARB, WETH, and USDT payouts are different pages. Arbitrum is One, not Nova. If you only needed USDC on BNB Chain, do not bridge. No Circle amount is locked.

Split the BNB, then read the USDC floor

Keep a fee remainder, then read the minimum USDC. A 3 second block on chain id 56 is not a promise that Arbiscan has the token. Sign while the wallet says BNB Chain. Look for the result on chain id 42161. Reject destinations you did not generate. Stay off Nova.

Frequently asked questions

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

The source marker 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means BNB, the gas coin on chain id 56. No ERC-20 approval.

Do I approve BNB before this Arbitrum USDC swap?

No. Native BNB uses 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, which is not an ERC-20. BscScan shows a native transfer on chain id 56. You only leave extra BNB for gas. The USDC you receive is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbiscan. That token needs ETH on Arbitrum One before it can move.

Which USDC should Arbiscan show?

Native Circle USDC, 0xaf88d065e77c8cC2239327C5EDb3A432268e5831, on chain id 42161. Bridged USDC.e is a different contract. If a pool wants that copy, this route is the wrong tool. Nova will not show the One balance. You still need ETH. The ARB token does not pay the fee.

What happens if I spend my last BNB?

The fee comes from the same native balance you are selling. Leave enough BNB for gas on chain id 56 or the send cannot be mined and no USDC appears. This page also does not promise a price or a completion time once a valid send does go through.
