Swap DAI from Ethereum to POL on Polygon

Swap DAI from Ethereum to POL on Polygon. Wallets that need POL for gas on chain 137 can spend Maker DAI held on Ethereum.

The output is native POL, written as 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Polygonscan shows that as the gas balance of chain id 137. The input is Maker DAI at 0x6B175474E89094C44Da98b954EedeAC495271d0F on Etherscan. You still need ETH on chain id 1 to pay for the send. A local sale of DAI for ETH would leave you on Ethereum, and that ETH cannot pay Polygon fees. Switch to chain id 137 and read the native gas line on Polygonscan.

Diagram for Swap DAI from Ethereum to POL on Polygon
DAI leaves Ethereum. POL is what can arrive on Polygon.

Gas on chain 137 is the point

Maker DAI on Ethereum cannot pay a Polygon fee. If the next signature is on chain id 137, the wallet needs POL. This pair converts DAI you already hold into that gas coin. It is the wrong shape if you wanted USDC or USDT to arrive instead. The quote on the screen is what you judge.

The placeholder is not a token row

Leave 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE out of the import list. On this route it means POL. On Ethereum it means ETH. Chain id 137 versus chain id 1 is the whole difference. Some wallets still print MATIC for this native balance.

Approve DAI, pay ETH

The contract that decreases is 0x6B175474E89094C44Da98b954EedeAC495271d0F. Confirm it on Etherscan. How to bridge assets between chains explains the source-chain signature. Blocks on Ethereum are about 12 seconds. Blocks on Polygon are about 2 seconds once POL can pay.

Skip the bridge when the pool is local

If you want ETH, USDC, or USDT on Ethereum, swap DAI on mainnet. This route is the wrong tool for those balances. If you already hold a Polygon stable and only need gas, swap that stable for POL on chain 137. Bridge from Ethereum when the DAI is still on mainnet.

Frequently asked questions

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

The output is native POL, written as 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Polygonscan shows that as the gas balance of chain id 137.

Does the POL show up as an ERC-20?

It shows up as the native balance on chain id 137. The address 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is a stand-in, not a contract you import from Polygonscan. Switch the wallet to Polygon and read the gas line. A custom token with that address will not be the real POL balance.

Can I start with only DAI in the wallet?

You need Maker DAI at 0x6B175474E89094C44Da98b954EedeAC495271d0F and you also need ETH. Chain id 1 charges ETH for the approval and the send. DAI is the asset being sold. ETH is the fee. POL is what you receive later, and it cannot pay the Ethereum transaction.

Is this a way to turn DAI into ETH?

No. Selling DAI for native ETH is a mainnet swap, and the ETH stays on chain id 1. This route sells DAI for native POL on Polygon. Use it when chain 137 gas is the gap. Skip it when the next trade is still on Ethereum.
