Swap WETH from Arbitrum One to USDC on BNB Chain

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

Sell 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1, WETH on Arbitrum One. Arbiscan, chain id 42161, not Nova. That contract is not the gas coin. Keep native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, for the fee. Receive Binance-Peg USDC at 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d, eighteen decimals, on BNB Chain. BscScan is the check. It is not Circle native USDC. Chain id 56 uses BNB for gas. Blocks about every 3 seconds, which is not a bridge timer.

Approve the wrapped contract, not the gas row

The allowance belongs to 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. If the approval screen shows the sentinel, you selected native ETH and this page is no longer the one you meant. Switch back. The approval costs ETH on chain id 42161. You do not approve the BSC USDC contract to receive it. An unlimited WETH allowance is more permission than a single trade needs. Set a cap when the wallet allows it.

Eighteen decimal peg versus wrapped ether

WETH uses eighteen decimals. So does 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. That shared scale is not a one-for-one redeem, and the token is a pegged dollar, not Circle's six-decimal native USDC. Read whole tokens on the quote. Confirm on BscScan that you are not looking at BSC USDT by mistake. The issuers and the tickers both differ from the WETH you sold.

Gas after arrival is BNB

The pegged USDC cannot pay chain id 56. Plan a BNB balance, because this route will not create one. BNB Chain is the destination. The source still needs its own ETH. A wallet that holds only WETH on Arbitrum One will stall at the approval even when the WETH amount is large.

Wrong if the coins are still unwrapped

Native ETH will not fund this quote. Neither will Binance-Peg ETH, which is not what you hold on Arbitrum. The page is also wrong if you wanted BSC USDT, native BNB, or Circle's Ethereum USDC. It is wrong if you wanted Ethereum WETH at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. Nova is the wrong network for the WETH contract on Arbiscan.

Frequently asked questions

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

Sell 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1, WETH on Arbitrum One. Arbiscan, chain id 42161, not Nova.

Does this spend my ETH or my WETH?

WETH at 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 is the sold token. Native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, pays the fee on chain id 42161 and should not be the amount in the quote. If you hold only ETH, this page is wrong until you wrap. Arbiscan should show the WETH contract, not Nova.

Is BSC USDC the same as Circle USDC on Arbitrum?

No. Circle on Arbitrum is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831, six decimals, and you are not receiving it. This output is 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d, Binance-Peg USDC, eighteen decimals. Check BscScan. If you need Circle's native contract, do not treat the peg as a substitute. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.

Can I move the USDC without BNB?

No. BNB Chain fees are paid in BNB, and this route's output is the pegged token, not the gas sentinel. Add BNB before you rely on a transfer. About 3 seconds is a block interval on chain id 56. It does not supply gas and it does not lock the WETH price against the peg.
