Swap USDT from Polygon to DAI on Ethereum

Swap USDT from Polygon to DAI on Ethereum. Tether USDT leaves Polygon. Maker DAI is what can arrive on Ethereum. Two different issuers, and neither one is Circle.

The debit contract is 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. The credit contract is 0x6B175474E89094C44Da98b954EedeAC495271d0F. Polygonscan is the source explorer. Etherscan is the DAI explorer. Chain id 137 uses POL. Chain id 1 uses ETH, with blocks around 12 seconds. Ethereum is the network that will hold the Maker token.

Keeping Tether means a different address

Ethereum USDT is 0xdAC17F958D2ee523a2206206994597C13D831ec7. This page never buys it. If an exchange deposit says Tether on Ethereum, stop. DAI from Maker is not a substitute just because both aim near one dollar.

DAI can leave the peg

Maker's token at 0x6B175474E89094C44Da98b954EedeAC495271d0F is not a Circle IOU and not a Tether IOU. The minimum on the quote already includes the market, not a promise of one DAI per one USDT. If that floor is too low, do not sign.

Gas is a third asset

POL leaves your Polygon wallet as a fee, not as the thing you are selling. ETH must already sit on Ethereum if you intend to transfer the DAI. Neither stablecoin pays those fees. The 0xEeee label is native gas, and this quote uses it on neither side as the traded asset.

Wrong chain, wasted approval

Approving 0xc2132D05D31c914a87C6611C10748AEb04B58e8F on Ethereum, or approving Ethereum USDT on Polygon, misses this route. The wallet has to be on chain id 137. Polygonscan should show that exact contract.

Frequently asked questions

What is the best way to swap USDT from Polygon to DAI on Ethereum?

The debit contract is 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. The credit contract is 0x6B175474E89094C44Da98b954EedeAC495271d0F. XAUConnect compares live routes and lets your own wallet sign.

Is DAI issued by Tether?

No. DAI is Maker's token at 0x6B175474E89094C44Da98b954EedeAC495271d0F. The token you sell is Tether at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F on Polygon. Circle is not on either side of this quote. Confirm DAI on Etherscan before you treat it as USDT. The sell side is Tether, and the buy side is Maker. Maker and Circle are different issuers.

What pays the Ethereum transaction after DAI arrives?

ETH on chain id 1. DAI cannot. Blocks there are about 12 seconds, and that figure is not a bridge finish. This route does not include the ETH. If you have no ETH on Ethereum, the DAI can arrive and wait. Polygon still charges POL for the send.

I wanted Circle USDC on Ethereum. Does DAI count?

No. Circle USDC there is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. This output is Maker DAI. Using DAI where a form demands USDC is the wrong route. Go back and choose the USDC output before any signature. DAI will not satisfy a Circle deposit. Maker is not a stand-in for Circle on that form.
