Swap WBTC from Ethereum to USDC on Polygon
Swap WBTC from Ethereum to USDC on Polygon. Holders of wrapped bitcoin who need Circle's native USDC on chain 137 spend WBTC and receive that dollar.
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. The dollars you receive are 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 on Polygonscan, Circle's native USDC, 6 decimals. USDC.e at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 is not the output. Gas to leave is ETH on chain id 1. Import the native USDC from Polygonscan once the wallet is on chain id 137. The bridged USDC.e row will stay unchanged, which is easy to misread as a failed route.
Not a Bitcoin withdrawal
Eight decimals in, six out, and not USDC.e
ETH to start, POL to finish

Frequently asked questions
What is the best way to swap WBTC from Ethereum to USDC on Polygon?
WBTC is an ERC-20, not bitcoin on the Bitcoin chain. You approve 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 on Etherscan.
Can the receiver be a Bitcoin address?
No. The output is Circle's native USDC on Polygon, 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. The input is WBTC at 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 on Etherscan, an ERC-20 with 8 decimals. Neither side is the Bitcoin network. Use an EVM address that can switch to chain id 137.
Why does a small WBTC figure represent a large dollar value?
WBTC uses 8 decimals, so a fraction of one token is a meaningful amount of wrapped bitcoin. The USDC you receive is set by the quote you sign, which this page does not fix. Read the minimum on that quote. The native USDC then displays with 6 decimals on Polygonscan.
What do I hold besides WBTC?
ETH on Ethereum, because chain id 1 will not take WBTC as a fee. POL on Polygon after arrival, because native USDC will not pay chain id 137. Blocks are about 12 seconds on the way out and about 2 seconds on Polygon. Both gas coins sit apart from the two token contracts.
