Exchange in 3 steps
-
Set the OP amount and paste your Cardano payout address on Cardano mainnet.
-
Create the order to lock the quote and see the deposit address.
-
Send OP to that deposit. After confirmations, 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.
- ADA not visible yet? Wait a few minutes, resync your wallet, then contact support with your order ID if the payout tx is already listed.
Optimism — Ethereum L2 with low fees
OP is the governance token of Optimism — 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 — research-driven layer-1
ADA is the native token of Cardano — 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 — 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
Is identity verification required to trade OP for ADA?
No. HideSwap operates as an anonymous no-KYC crypto exchange — no profile, no ID upload, and no funded account for Optimism → Cardano.
How long is a OP → ADA order?
Typical completion is a few minutes. Optimism mainnet and Cardano mainnet confirmation times set the pace.
Do you custody OP or ADA?
No. You send OP yourself and ADA is paid to the address you enter — HideSwap does not keep a wallet balance for you.
What if I pick the wrong OP network?
Match the network printed on the order (Optimism mainnet). A mismatch can strand the deposit — check the swap safety notes first.
