Exchange in 3 steps
-
Choose how much ZEC to send and enter your Optimism address on Optimism mainnet.
-
Hit Exchange to open your order page with the live rate and deposit details.
-
Transfer ZEC to the address on your order — after confirmations, OP is sent to your wallet automatically.
What do you need to know?
- Zcash confirmations follow mainnet block times — usually a few minutes.
- Transparent (t-) and shielded (z-) addresses are not interchangeable — use the type your order specifies.
- Shielded payouts may take longer to appear depending on wallet support.
- OP not visible yet? Wait a few minutes, resync your wallet, then contact support with your order ID if the payout tx is already listed.
Zcash — optional shielded privacy
ZEC supports transparent and shielded addresses — pick the receive format your wallet actually supports.
Transparent vs shielded ZEC
Sending to the wrong address type is a common failure mode.
If unsure, ask support which format your order uses before broadcasting.
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 not received?
Confirm your wallet is on Optimism mainnet and fully synced.
OP payout tips
- Payouts go to Optimism — verify your wallet RPC is set to Optimism, not Ethereum mainnet.
- Check Optimistic Etherscan with the payout tx hash from your order page.
- Allow a minute for your wallet to refresh after the explorer shows the transfer.

Frequently asked questions
Do I need KYC to swap ZEC to OP?
No. SendSwap is a non-custodial instant exchange — no account, no ID checks, and no KYC for Zcash to Optimism swaps.
How long does ZEC to OP take?
Most swaps finish in 1–5 minutes. Timing depends on Zcash mainnet and Optimism mainnet confirmations and current network load.
Is ZEC to OP non-custodial?
Yes. You send ZEC from your wallet and receive OP directly to the address you provide — SendSwap never holds your keys.
What if I send ZEC on the wrong network?
Always match the network on your order page (Zcash mainnet for deposits). Wrong-network sends may not be credited — read our swap safety guides before you send.
