Swap WETH from Base to ETH on BNB Chain
Swap WETH from Base to ETH on BNB Chain. Base WETH leaves, and pegged ETH arrives as a BEP-20 on BNB Chain.
Spend wrapped ETH at 0x4200000000000000000000000000000000000006. That contract is on Base, chain 8453, and Basescan is where you read the approval. Receive 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 on chain 56. BscScan lists it as pegged ETH. It is not native ETH, it is not WETH, and it cannot pay fees. Native BNB is the placeholder 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on this destination, and this quote does not deliver that placeholder. Blocks on BNB Chain are about 3 seconds.

Frequently asked questions
What is the best way to swap WETH from Base to ETH on BNB Chain?
Spend wrapped ETH at 0x4200000000000000000000000000000000000006. That contract is on Base, chain 8453, and Basescan is where you read the approval.
Is pegged ETH the same as WETH?
No. WETH on Base is 0x4200000000000000000000000000000000000006, and that is the input you spend. WETH on Ethereum is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. The output here is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 on BscScan, a pegged BEP-20. None of those three contracts is native BNB. If you needed the gas coin, buy BNB instead of this pegged token.
Will this ETH pay BNB Chain fees?
No. Gas on chain 56 is BNB, often labeled 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE in interfaces. Pegged ETH cannot be used as that fee. You need BNB in the account before the new token can be transferred. Base ETH used to approve WETH does not fill that gap. Chain 56 blocks are about 3 seconds only after that BNB is already there.
What if I only hold native ETH on Base?
Then wrap it into 0x4200000000000000000000000000000000000006 before this route can see a balance, or pick a route that sells native ETH directly. Native ETH is the gas coin on chain 8453 and is not an ERC-20 approval. This page assumes the wrapper is already in the wallet.
