Exchange in 3 steps
-
Choose how much OP to send and enter your Cardano address on Cardano mainnet.
-
Hit Exchange to open your order page with the live rate and deposit details.
-
Transfer OP to the address on your order — after confirmations, ADA is sent to your wallet automatically.
What do you need to know?
- 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
Do I need KYC to swap OP to ADA?
No. SendSwap is a non-custodial instant exchange — no account, no ID checks, and no KYC for Optimism to Cardano swaps.
How long does OP to ADA take?
Most swaps finish in 1–5 minutes. Timing depends on Optimism mainnet and Cardano mainnet confirmations and current network load.
Is OP to ADA non-custodial?
Yes. You send OP from your wallet and receive ADA directly to the address you provide — SendSwap never holds your keys.
What if I send OP on the wrong network?
Always match the network on your order page (Optimism mainnet for deposits). Wrong-network sends may not be credited — read our swap safety guides before you send.
