Swap ETH from Arbitrum One to DAI on Ethereum

Swap ETH from Arbitrum One to DAI on Ethereum. Native ETH leaves Arbitrum One and Maker DAI arrives on Ethereum.

You spend the native gas balance on Arbitrum One, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, chain id 42161, not Nova. Arbiscan is the explorer for that side. Do not spend the last wei, because ETH also pays the fee. Maker DAI at 0x6B175474E89094C44Da98b954EedeAC495271d0F is what Etherscan should show on the way in. That contract is eighteen decimals on Ethereum, chain id 1. Blocks there are about 12 seconds. The interval is a property of Ethereum, not a delivery promise.

Diagram for Swap ETH from Arbitrum One to DAI on Ethereum
ETH leaves Arbitrum One. DAI is what can arrive on Ethereum.

DAI is Maker's collateral stablecoin

0x6B175474E89094C44Da98b954EedeAC495271d0F is issued through Maker, not through Circle and not through Tether. It does not become USDC because a wallet groups stablecoins together. Eighteen decimals means the base unit is tiny compared with six-decimal USDC or USDT. Read the DAI amount on the quote in whole tokens. If a lending market only accepts Circle's contract, this arrival will not be eligible collateral there.

Selling gas means reserving gas

The sentinel names native ETH, which is the fee coin on Arbitrum One. A quote for the entire balance cannot pay for itself. Leave a remainder. The WETH contract 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 is a different row. Selling wrapped ether is a different route. If you unwrap WETH first so you can use this page, that unwrap is its own transaction and also costs ETH.

What changes in the two portfolios

Arbitrum One loses native ETH. Ethereum can gain DAI. You do not gain ETH on chain id 1, so you do not suddenly have mainnet gas. If you will move the DAI after it appears, you need ETH on Ethereum from somewhere else to pay that later fee. How to bridge assets between chains is a useful companion when the receive asset cannot pay the next transaction.

Wrong output if you wanted a fiat stablecoin

Leave this page if the destination whitelist says Circle USDC or Tether USDT. Maker DAI will not match those addresses. Leave it if you wanted WETH or native ETH on Ethereum. Leave it if the wallet is on Arbitrum Nova, or if the ETH you hold is already wrapped. A local wrap on Arbitrum One never reaches the Maker contract on Etherscan.

Frequently asked questions

What is the best way to swap ETH from Arbitrum One to DAI on Ethereum?

You spend the native gas balance on Arbitrum One, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, chain id 42161, not Nova. Arbiscan is the explorer for that side.

Is DAI the same as USDC with another name?

No. Circle USDC on Ethereum is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. This route can credit Maker DAI at 0x6B175474E89094C44Da98b954EedeAC495271d0F. Different issuer, different decimals, different contract. Confirm the page on Etherscan. If your app's allowlist names Circle, do not send this route and hope the ticker is close enough. Confirm the address on the explorer before you sign.

Will I have ETH for gas on Ethereum afterward?

Not from this quote. You sold native ETH on Arbitrum One and the output is DAI. Chain id 1 still charges ETH for transactions. Receiving DAI does not create that gas balance. If the Ethereum wallet is empty of ETH, you can hold DAI and still be unable to transfer it until some ETH arrives by another path.

What if my Arbitrum balance is WETH, not ETH?

Then this page is the wrong one. It spends the sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, which is native ETH. Wrapped ether lives at 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. Unwrap first if you truly want this route, and keep enough ETH for the unwrap and the swap. Arbitrum Nova is not a substitute network.
