Swap USDC from Polygon to DAI on Ethereum
Swap USDC from Polygon to DAI on Ethereum. Circle USDC leaves Polygon. Maker DAI is what can arrive on Ethereum. You are switching issuers, not moving one dollar token under a new name.
The sale is 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 on chain id 137. The purchase is 0x6B175474E89094C44Da98b954EedeAC495271d0F, Maker DAO's DAI on chain id 1. Polygonscan records the USDC. Etherscan records the DAI. POL pays gas on Polygon. ETH pays gas after arrival. Ethereum is where that DAI can be checked.
DAI is Maker, not Circle and not Tether
USDC.e will not fill the order
DAI cannot pay mainnet fees
Leave POL behind on chain 137

Frequently asked questions
What is the best way to swap USDC from Polygon to DAI on Ethereum?
The sale is 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 on chain id 137. The purchase is 0x6B175474E89094C44Da98b954EedeAC495271d0F, Maker DAO's DAI on chain id 1.
Is DAI the same organization as USDC?
No. USDC is issued by Circle. DAI is Maker's token at 0x6B175474E89094C44Da98b954EedeAC495271d0F. This route sells Circle on Polygon and buys Maker on Ethereum. If your books must stay in Circle, use a USDC output. Etherscan is where the DAI contract is confirmed. A shared dollar target is not a shared issuer.
What if my Polygon balance says USDC but the swap will not quote?
You may be holding USDC.e at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 rather than 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. This page is wrong for the bridged copy. Polygonscan lists both. Chain id 137 and a POL balance are still required for gas. Approve only the native contract. The ticker USDC on its own is not enough.
Do I need ETH before DAI arrives?
You need POL on Polygon to send, and you need ETH on Ethereum if you want to move the DAI afterward. DAI itself will not pay chain id 1. The route does not include that ETH. About 12 second Ethereum blocks are not the bridge clock.
