Three steps on Web3Swap
-
Enter the OP size and paste the Cardano payout address for Cardano mainnet on this Web3Swap ticket.
-
Confirm Exchange to lock the live Web3Swap quote and reveal this ticket’s deposit details.
-
Broadcast exactly that OP amount to the deposit. After Optimism mainnet confirms, ADA is paid to your wallet.
Before you broadcast
- Optimism confirmations are usually fast — often within a minute.
- Send OP on Optimism mainnet only — not Ethereum, Base, or Arbitrum unless your order says otherwise.
- Use an Optimism-compatible wallet and address (0x…). Leave enough ETH on Optimism for gas if sending ERC-20 tokens.
- If ADA is late, refresh your wallet and re-check the ticket. When a payout hash is already listed, email or SimpleX support with your Exchange ID — Web3Swap has no login that lists expired orders.
Optimism tickets — L2 ETH and OP tokens
OP governs Optimism’s rollup. Web3Swap OP tickets need an Optimism wallet — an L1 Ethereum send here is usually unrecoverable.
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 tickets — ADA address format
ADA is Cardano’s native proof-of-stake asset. On Web3Swap, paste a mainnet address your wallet owns and broadcast only ADA — wrong-network sends will not credit the ticket.
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 — 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.
Deposit checklist
Chain mismatches and bad addresses are the usual failure modes — skim these notes before you fund the deposit.

More anonymous no-KYC lanes and chain notes for each coin.
FAQ for this route
Do I need KYC or a Web3Swap login for OP → ADA?
No. A standard Optimism → Cardano ticket on Web3Swap skips signup and ID upload. You stay self-custodial on both legs.
How soon does ADA usually arrive?
After the Optimism mainnet deposit is final, many payouts leave within minutes. Congestion on Optimism mainnet or Cardano mainnet can stretch that — mempools and fees set the clock, not a compliance hold.
Does Web3Swap custody my OP or ADA?
No. You broadcast OP from a wallet you control; ADA pays only to the address you paste. Nothing sits as a named Web3Swap balance.
What if I send OP on the wrong rail?
Match Optimism mainnet exactly as printed on the Web3Swap ticket badge. A wrong-chain deposit often cannot be credited automatically — verify before you broadcast.
