Swap ETH from Ethereum to BNB on BNB Chain

Swap ETH from Ethereum to BNB on BNB Chain. Someone who needs BNB gas on chain 56 spends native ETH on Ethereum to receive it.

Both sides of the route use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. On Ethereum that string means native ETH, the gas coin Etherscan shows for chain id 1. On BNB Chain the same string means native BNB, the gas coin BscScan shows for chain id 56. They are not one balance viewed twice. You are selling ETH to receive BNB. Leave extra ETH on mainnet so the send can pay its own fee. Mainnet blocks are about 12 seconds.

ETH leaves Ethereum. BNB is what can arrive on BNB Chain.

One placeholder, two gas coins

Do not import 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE as a custom token on either chain. It is a stand-in. The wallet shows ETH while it is on chain id 1 and BNB while it is on chain id 56. If both lines look unchanged, you are still looking at the source network.

What this pair is for

People use it to turn mainnet ETH into the coin that pays fees on BNB Chain. A new chain 56 wallet can then move tokens. It is a direct way to fund gas, and a poor way to keep a dollar balance. If you wanted USDT or USDC on chain 56, pick the route whose output is that contract.

Skip it when the next trade is on Ethereum

This route is the wrong tool for buying WETH, USDC, or USDT on mainnet. Those trades stay on chain id 1 and never credit native BNB. Ethereum is only the network you sign on. Wrapping ETH into 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 is also a local action and does not produce BNB.

After BNB arrives

Switch the wallet to chain id 56 and read the native balance on BscScan. Blocks there are about 3 seconds. The BNB you received can pay the next approval or swap. Spend less than the full amount if you still need gas for that follow-up transaction.

Frequently asked questions

What is the best way to swap ETH from Ethereum to BNB on BNB Chain?

Both sides of the route use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. On Ethereum that string means native ETH, the gas coin Etherscan shows for chain id 1.

Why do tokenIn and tokenOut look identical?

Both are 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE because each chain uses that placeholder for its own gas coin. Etherscan interprets it as ETH on chain id 1. BscScan interprets it as BNB on chain id 56. The path is what changes the meaning. You are not moving one native balance from one explorer to the other.

How much ETH should I keep back?

Enough to pay the chain id 1 fee after the amount you sell. Native ETH funds both the trade and the gas, so a max send can fail. Ethereum blocks are about 12 seconds. The BNB you receive does not pay that mainnet fee, because it exists only on chain id 56.

Is wrapped BNB on Ethereum the same result?

A token with a BNB ticker on Ethereum is an ERC-20 on chain id 1. It will not pay gas on BNB Chain. This route delivers native BNB, which BscScan shows as the chain's gas coin. Use it when chain 56 fees are the gap. Skip it when you are still trading on Ethereum.
