Optimism → Mainnet

Swap ETH to ADA

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

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

Address and network checks

Use the order’s OP Mainnet deposit address for ETH, and your own Cardano receiving address for ADA. Keep the refund address on OP Mainnet; the payout address is not automatically a valid refund destination.

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 ADA

Choose Cardano using the Mainnet option shown in this directory. Follow the selected provider’s exact deposit instructions before sending. Use a Cardano payment/receiving address from your wallet. A staking reward address is used for a different purpose and should not be substituted for a regular receiving address. This listed ADA/Mainnet 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.

How much ADA 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 ADA has arrived?

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