Swap DAI from Ethereum to ETH on Base
Swap DAI from Ethereum to ETH on Base. A wallet that needs ETH for gas on chain 8453 can spend Maker DAI held on Ethereum.
The output is native ETH on Base, written as 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Basescan shows that as the gas balance of chain id 8453. 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 the ETH on Ethereum, and that balance cannot pay Base fees. Mainnet blocks are about 12 seconds. Switch to Base and read the native line on Basescan. Base WETH at the 0x4200 predeploy is a different asset and is not this output.
Base gas is the reason to open it
The placeholder is the gas line
Approve DAI, pay mainnet ETH

Frequently asked questions
What is the best way to swap DAI from Ethereum to ETH on Base?
The output is native ETH on Base, written as 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Basescan shows that as the gas balance of chain id 8453.
Does the ETH show up as the WETH predeploy?
No. It shows up as the native gas balance on Base, chain id 8453. The address 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is a stand-in, not a contract you import. Base WETH is 0x4200000000000000000000000000000000000006. Switch the wallet to Base and read the gas line on Basescan.
Can I start with only DAI?
You need Maker DAI at 0x6B175474E89094C44Da98b954EedeAC495271d0F and you also need ETH on Ethereum. Chain id 1 charges ETH for the approval and the send. DAI is the asset. ETH on mainnet is the fee. ETH on Base is what you receive later and cannot pay the first transaction.
Is this how I turn DAI into mainnet ETH?
No. Selling DAI for native ETH on Ethereum keeps the ETH on chain id 1. This route sells DAI for native ETH on Base. Use it when chain 8453 gas is the gap. Skip it when the next trade is still on Ethereum.
