How the swap works
-
Type the OP amount and paste your Cardano payout address on Cardano mainnet.
-
Press Exchange to open the live quote and the deposit address for this order.
-
Broadcast OP to that deposit. After the required confirmations, ADA is sent to your wallet.
Check these before you send
- Optimism confirmations are usually fast β often within a minute.
- Send OP on Optimism mainnet only β not Ethereum, Base, or Arbitrum unless your order says otherwise.
- Use an Optimism-compatible wallet and address (0xβ¦). Leave enough ETH on Optimism for gas if sending ERC-20 tokens.
- If ADA has not appeared yet, wait a few minutes and refresh the wallet. When the order already shows a payout tx, contact support with your order ID.
Optimism β Ethereum L2 with low fees
OP is the governance token of Optimism β an Ethereum rollup with fast, low-cost transfers and deep Superchain liquidity.
OP on Optimism mainnet
Use an Optimism wallet for deposits. L1 Ethereum or other L2 sends may not be credited.
Leave enough ETH on Optimism for gas when moving OP or other tokens.
Cardano β research-driven layer-1
ADA is the native token of Cardano β a proof-of-stake network focused on security and formal verification.
ADA payout delays
Resync your Cardano wallet if the order shows a sent transaction but balance is unchanged.
When will ADA arrive?
Cardano block times are around 20 seconds β payouts typically follow within several blocks.
- Use a Shelley-era Cardano address compatible with your wallet.
- Check a Cardano explorer with the payout tx hash from your order page.
- Allow a few extra minutes if your wallet is still syncing the latest epoch.

Frequently asked questions
Does OP to ADA require KYC or an account?
No. PeakSwap does not ask for a profile, ID documents, or a hosted balance for Optimism to Cardano.
How long until ADA arrives?
Many orders finish in a few minutes. Optimism mainnet deposit confirmations and Cardano mainnet payout time set the wait.
Do you hold OP or ADA for me?
No. You send OP from a wallet you control and ADA is paid to the address you provide β PeakSwap does not keep a user wallet.
What if I send OP on the wrong chain?
Use Optimism mainnet exactly as shown on the order. A wrong-network send may not be credited β read the swap safety notes first.
