Optimism → ERC20

Swap ETH to DAI

Exchange ETH from OP Mainnet into DAI on Ethereum. The provider waits for the ETH deposit before arranging the DAI payout on the destination network. Track those as separate transactions rather than using a sending-chain confirmation as proof of receipt.

Ethereum (Optimism) to Dai (ERC20)

You send
Ethereum (Optimism)ETH · Optimism
You receive
Dai (ERC20)DAI · ERC20

Enter your amount to check live availability for ETH on Optimism → DAI on ERC20. A provider quote is required before you can create a swap.

Address and network checks

Both OP Mainnet and Ethereum use EVM-style addresses. An identical address string cannot confirm the network. Check OP Mainnet in the sending wallet and Ethereum in the receiving wallet separately.

Sending ETH

Select OP Mainnet, often labeled Optimism. Its ETH balance and token balances are separate from those on Ethereum mainnet. Native ETH and wrapped Ether (WETH) are different assets. Use the ETH balance on the selected network; do not substitute WETH for an ETH deposit.

For a standard self-custody transfer on OP Mainnet, allow for network fees in ETH in addition to the amount you send. Wallet sponsorship and exchange withdrawal charges can differ; check the sending wallet’s final fee.

Receiving DAI

Choose Ethereum mainnet in the wallet. Base, Arbitrum and OP Mainnet use separate balances even when the account address looks identical. DAI and USDS have separate token identities. Send DAI for a DAI order; holding or using an upgraded token does not make it interchangeable with this deposit asset. This listed DAI/ERC20 option has no separate memo field. If your destination requires additional instructions that this form cannot supply, choose another compatible destination before creating an order.

Refund address for this pair

Enter a refund address that accepts ETH on Optimism. The refund is sent in ETH on Optimism; verify that your refund wallet supports this exact asset and network.

About this ETH / DAI route

Which network fee applies when sending ETH?

For a standard self-custody transfer on OP Mainnet, allow for network fees in ETH in addition to the amount you send. Wallet sponsorship and exchange withdrawal charges can differ; check the sending wallet’s final fee.

What should I check before receiving DAI on Ethereum?

DAI and USDS have separate token identities. Send DAI for a DAI order; holding or using an upgraded token does not make it interchangeable with this deposit asset. This listed DAI/ERC20 option has no separate memo field. If your destination requires additional instructions that this form cannot supply, choose another compatible destination before creating an order.

How much DAI will I get for ETH?

Enter your ETH amount to see an approximate receive amount. Click Find the best route to compare providers. Floating rates can change before conversion; fixed quotes follow the selected provider’s terms.

Does a confirmed ETH deposit mean my DAI has arrived?

No. Deposit confirmation on OP Mainnet, provider processing and payout on Ethereum are separate steps. Use Track swap to see the order status, then check the DAI balance on the receiving network. A live quote or historical route check does not guarantee completion time.
