Swap ETH from Ethereum to USDC on Polygon
Swap ETH from Ethereum to USDC on Polygon. You spend native ETH on Ethereum and a chain 137 wallet receives Circle's native USDC.
Native ETH is marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, the gas coin Etherscan shows on chain id 1. You do not approve it. The dollar that arrives is 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 on Polygonscan, 6 decimals. Bridged USDC.e at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 is not the receipt. Leave ETH behind for the mainnet fee. Blocks there are about 12 seconds. Import 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 from Polygonscan. A wallet that only tracks USDC.e will hide the dollars this route delivers. Leave POL on that same chain 137 address or the new USDC cannot move after it shows up. Confirm the contract before you deposit.

Frequently asked questions
What is the best way to swap ETH from Ethereum to USDC on Polygon?
Native ETH is marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, the gas coin Etherscan shows on chain id 1. You do not approve it.
Do I approve a contract for the ETH?
No. Native ETH uses 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE as a placeholder, not a token you import. You sign a send on chain id 1. Keep enough ETH unspent to cover gas, because the amount you bridge and the fee come from the same balance. Etherscan shows that native balance, not an ERC-20 approval.
Which USDC row should increase?
The native one, 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 on Polygonscan, 6 decimals. USDC.e at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 stays put. If the app you are funding lists the bridged address, this route delivers the wrong contract. Match the allowlist before you deposit. Match the allowlist before you deposit the dollars.
When is an Ethereum swap enough?
When the dollars should remain on chain id 1 as Circle USDC at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. This bridge is the wrong tool for that balance. Open it only if the next use of the money is on Polygon and the accepted contract is the native USDC.
