Swap WBTC from Ethereum to BNB on BNB Chain

Swap WBTC from Ethereum to BNB on BNB Chain. A chain 56 wallet that needs gas can spend wrapped bitcoin on Ethereum and receive native BNB.

WBTC at 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 is an 8 decimal ERC-20 on Etherscan, not a coin on the Bitcoin chain. Native BNB is marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE and shows up as the gas balance on BscScan for chain id 56. You do not import that placeholder. You do approve the WBTC contract, and you pay the approval in ETH. Ethereum blocks are about 12 seconds.

Diagram for Swap WBTC from Ethereum to BNB on BNB Chain
WBTC leaves Ethereum. BNB is what can arrive on BNB Chain.

Gas on chain 56 is the reason to open it

Wrapped bitcoin cannot pay a BNB Chain fee. If the next signature has to happen on chain id 56, the wallet needs native BNB. This pair turns WBTC you already hold on Ethereum into that gas coin. It is the wrong shape of trade if you wanted a dollar stable to arrive instead.

Do not treat this as a bitcoin send

A Bitcoin address will not accept WBTC, and it will not accept BNB. The route never leaves the two EVM chains. Etherscan is where 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 decreases. BscScan is where the native BNB balance increases. How cross-chain bridges work describes that split. It is not a Bitcoin bridge.

When the pool on Ethereum is enough

If you want ETH, WETH, USDC, or USDT on mainnet, sell WBTC there. This route is the wrong tool for those balances. If you already hold BNB Chain assets and only need a little BNB, swap those assets on chain 56. Bridge from Ethereum when the wrapped bitcoin is still on mainnet.

Leave BNB for the next click

Chain id 56 blocks about every 3 seconds and charges BNB. The coin you just received is that fee token, so it can pay the follow-up trade. Spending all of it in one transfer strands any other token in the same wallet. Keep a remainder.

Frequently asked questions

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

WBTC at 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 is an 8 decimal ERC-20 on Etherscan, not a coin on the Bitcoin chain. Native BNB is marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE and shows up as the gas balance on BscScan for chain id 56.

Is the BNB an ERC-20 I should add by contract?

No. Native BNB uses the placeholder 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE and appears as the gas balance once the wallet is on chain id 56. Importing that string as a token creates a junk row. Confirm the increase on BscScan's native balance. The ERC-20 you approve is WBTC, on Etherscan.

What is WBTC if it is not bitcoin?

An ERC-20 at 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599, 8 decimals, on Ethereum. This route can spend that contract. It cannot move coins on the Bitcoin network. If your goal is a Bitcoin wallet balance, stop. If your goal is BNB gas funded from that ERC-20, this is the pair.

Why do I still need ETH?

Because the spend starts on chain id 1. WBTC cannot pay Ethereum gas, and the BNB you will receive does not exist on Ethereum yet. Hold ETH for the approval and the send. Blocks are about 12 seconds. After arrival, BNB covers chain id 56.
