Swap WBTC from Ethereum to USDC on BNB Chain

Swap WBTC from Ethereum to USDC on BNB Chain. Holders of wrapped bitcoin who need Binance-Peg dollars spend WBTC and receive that USDC on chain 56.

WBTC is an ERC-20, not bitcoin on the Bitcoin chain. You approve 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 on Etherscan. It uses 8 decimals. A Bitcoin address cannot receive it, and this route cannot send it there. The dollars you receive are Binance-Peg USDC at 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d on BscScan, 18 decimals. Gas to leave Ethereum is ETH, chain id 1, about 12 seconds a block. Keep a little ETH beside the WBTC.

This is not a Bitcoin withdrawal

This route is the wrong tool if the destination is a Bitcoin address or a bitcoin exchange deposit that asks for the Bitcoin network. WBTC stays an Ethereum token until this route spends it, and the output is a dollar on BNB Chain. Redeeming WBTC for bitcoin, if your custodian supports it, is a different process and does not use BscScan.

Eight decimals in, eighteen out

Check 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 on Etherscan for the 8 decimal WBTC balance you are spending. Check 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d on BscScan for the 18 decimal pegged USDC you receive. Circle USDC on Ethereum is not the receipt. A wallet that mixes those decimal fields will invent the size of the trade.

ETH to start, BNB to finish

WBTC does not pay Ethereum gas. Keep ETH on chain id 1 for the approval. Pegged USDC does not pay BNB Chain gas. Keep BNB on chain id 56, where blocks are about 3 seconds. BNB Chain is the network the dollars land on.

When a mainnet sale is enough

WBTC already trades against Circle USDC and Tether on Ethereum. Use those pools when the dollars should stay on chain id 1. This bridge is for a wallet that needs the Binance-Peg contract specifically. Selling WBTC on mainnet never creates 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d.

Frequently asked questions

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

WBTC is an ERC-20, not bitcoin on the Bitcoin chain. You approve 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 on Etherscan.

Can I paste a Bitcoin address as the receiver?

No. The output is an ERC-20 on BNB Chain, Binance-Peg USDC at 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. The input is WBTC at 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 on Etherscan, also an ERC-20. Neither side is the Bitcoin network. A Bitcoin address will not credit this route. Use an EVM address that is ready for chain 56.

Why does a small WBTC amount look large in dollars?

WBTC uses 8 decimals, so 0.01 WBTC is a meaningful unit of wrapped bitcoin, not a dust balance. The USDC you receive is priced by the quote you sign, which this page does not fix. Read the minimum on the quote. The pegged USDC then shows 18 decimals on BscScan, which is a display detail, not a promise of size.

What do I need besides WBTC?

ETH on Ethereum for gas, because chain id 1 will not accept WBTC as a fee. After the route, BNB on chain id 56, because pegged USDC will not pay those fees. Blocks are about 12 seconds on the way out and about 3 seconds on BNB Chain. Both gas coins are separate from the two token contracts.
