Swap ETH from Arbitrum One to USDC on BNB Chain

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

Spend the gas sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Arbitrum One, which is native ETH, not WETH. Arbiscan, chain id 42161, not Nova. Leave a fee remainder in that same balance. Receive 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d on BNB Chain. BscScan calls it Binance-Peg USDC, eighteen decimals, not Circle's native USDC. Chain id 56, gas in BNB, blocks about 3 seconds. The block interval is not a fill promise.

You are selling the fee coin

Native ETH on chain id 42161 pays gas and is the asset in the quote. The full balance will not clear. WETH at 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 is untouched. If that wrapped row is what you hold, this page will not see it. Nova's ETH is a different chain. The sentinel hex will appear again on BNB Chain in other quotes, but there it would mean BNB. Here, on the source, it means the ETH you are selling.

Pegged dollars, not Circle's contract

0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d is the BSC USDC token this route names. It uses eighteen decimals. Circle's native USDC on Arbitrum and Ethereum uses six, and those addresses are different. Do not tell a Circle redemption desk this balance is their native token until you have matched BscScan against their list. If the list does not include this peg, the route is the wrong tool for that desk.

BNB still missing after the credit

Pegged USDC cannot pay a BNB Chain fee. If chain id 56 has no BNB, the new dollars wait. This quote does not attach a gas stipend. How to bridge assets between chains is worth a look before you empty the source ETH and discover the destination cannot move. Price of ETH versus the peg can shift. Reread the minimum.

Wrong when you wanted ETH to remain ETH

This output is not Binance-Peg ETH at 0x2170Ed0880ac9A755fd29B2688956BD959F933F8, not native BNB, and not Ethereum USDC at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. It is the wrong page for a local wrap, the wrong page for WETH holders, and the wrong page if you needed Circle's six-decimal USDC on Ethereum specifically.

Frequently asked questions

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

Spend the gas sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Arbitrum One, which is native ETH, not WETH. Arbiscan, chain id 42161, not Nova.

Is this the Circle USDC I can redeem natively?

Do not assume that. The receive contract is 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d, Binance-Peg USDC on BNB Chain, eighteen decimals. Circle's Arbitrum USDC is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 and is not the output. You spend native ETH on chain id 42161. Confirm the peg on BscScan and against the issuer you need.

Why can't I sell all my Arbitrum ETH?

Because the sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is both the asset and the fee on Arbitrum One. Gas has to remain. WETH will not cover that fee. Chain id 42161 is required, not Nova. About 3 seconds is a BNB Chain block interval on the destination and has nothing to do with how much ETH you must reserve.

Does pegged USDC let me transact on BNB Chain immediately?

Only if the wallet already holds BNB for gas. The BEP-20 is not the fee token. Native BNB would have been the sentinel output, and this route does not use it. Fund BNB separately, or pick a route that delivers BNB, before you depend on moving 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d.
