Swap ETH from BNB Chain to WETH on Arbitrum One

Swap ETH from BNB Chain to WETH on Arbitrum One. You send Binance-Peg ETH on BNB Chain and you receive WETH on Arbitrum One.

The source is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. Approve it on BscScan, chain id 56, gas in BNB, blocks about 3 seconds. Arbitrum One WETH is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. Match it on Arbiscan. It is not the peg, not native ETH, and not mainnet WETH. Chain id 42161, not Nova. Gas is ETH. The wrapper cannot pay that gas. The ARB token cannot either.

One peg in, a different wrapper out

This page spends only 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. It does not spend BNB, and it does not wrap ETH that already sits on Arbitrum. If the peg balance is empty, there is nothing to approve. Keep BNB for gas on chain id 56. The names both say ether. The contracts do not match.

Arbitrum WETH still needs a native ETH balance

0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 arriving does not top up ETH. Arbiscan shows a token, not a native credit. Every later move costs ETH. A fresh wallet can display WETH and still fail a transfer. BNB left behind does not become that ETH. Nova will not show the balance.

Native ETH is the page that pays the gas coin

If you wanted spendable gas, this wrapper is the wrong tool. Native USDC and USDT are the wrong tool if you wanted dollars. The ARB token is the wrong tool if you wanted the governance token. BNB Chain is only where the peg sits. No WETH amount is promised.

Do not drain BNB to enlarge the peg

The fee and the trade are different balances. Draining BNB stalls the approval. Read the minimum WETH before you sign on chain id 56. A 3 second block is not an Arbiscan timestamp. If the floor is too small, leave the quote unsigned. Nova is the wrong network for this wrapper, chain id 42161.

Frequently asked questions

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

The source is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. Approve it on BscScan, chain id 56, gas in BNB, blocks about 3 seconds.

Are the peg and Arbitrum WETH the same token?

No. The peg is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 on BscScan. Arbitrum WETH is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 on Arbiscan, chain id 42161. Mainnet WETH is a third address. This page pays the Arbitrum contract only. You need BNB to send and ETH to move the result. Nova is not the chain.

Can I unwrap this WETH into the ARB token?

No. Unwrapping, where a pool offers it, returns native ETH and still costs ETH as gas. It does not mint ARB. If you needed the gas coin, open the native ETH page. If you needed ARB, open that page. This route pays the wrapper only.

What if I meant to send BNB, not the peg?

Stop. BNB is the gas coin and has its own route to Arbitrum WETH. Approving 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 will not spend BNB. Check the native balance on BscScan. This page is the wrong tool for a BNB sale, even when the payout ticker looks like ether.
