Exchange in 3 steps
-
Choose how much OP to send and enter your Zcash address on Zcash 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, ZEC 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.
- ZEC 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.
Zcash — optional shielded privacy
ZEC supports transparent and shielded addresses — pick the receive format your wallet actually supports.
ZEC receipt troubleshooting
Confirm address type matches your wallet. Rescan the blockchain in your Zcash client if needed.
Transparent vs shielded payouts
Zcash supports both transparent (t-) and shielded (z-) addresses — they are not interchangeable.
- Use the address type your wallet actually supports before placing the order.
- Shielded payouts may take longer to appear depending on wallet software.
- If the order shows a sent tx but balance is zero, rescan the chain in your Zcash client first.

Frequently asked questions
Do I need KYC to swap OP to ZEC?
No. SendSwap is a non-custodial instant exchange — no account, no ID checks, and no KYC for Optimism to Zcash swaps.
How long does OP to ZEC take?
Most swaps finish in 1–5 minutes. Timing depends on Optimism mainnet and Zcash mainnet confirmations and current network load.
Is OP to ZEC non-custodial?
Yes. You send OP from your wallet and receive ZEC 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.
