Mainnet → ERC20

Swap OP to DAI

Exchange OP from OP Mainnet into DAI on Ethereum. The provider waits for the OP 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.

Optimism (Mainnet) to Dai (ERC20)

You send: Optimism (Mainnet)OP · Mainnet
You receive: Dai (ERC20)DAI · ERC20

Enter your amount to check live availability for OP on Mainnet → 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 OP

Choose OP Mainnet using the Mainnet option shown in this directory. Follow the selected provider’s exact deposit instructions before sending. Send the OP token on the network specified by the order. If sending from a normal self-custody wallet on OP Mainnet, allow for gas paid in ETH, not OP.

For a standard self-custody transfer on OP Mainnet, allow for network fees in ETH, separately from your OP balance. 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 OP on Mainnet. The refund is sent in OP on Mainnet; verify that your refund wallet supports this exact asset and network.

Does a confirmed OP deposit mean my DAI has arrived?
