FAQ
Common questions about ZeroK.
What happens if I lose access?
Your wallet is your recovery key. When you deposit, ZeroK encrypts your note with a key derived from your wallet signature. Reconnect the same wallet and all your funds come back automatically, across browsers, devices, and time. There are no files to back up.
The one thing you must keep safe is your wallet itself. Lose your Solana seed phrase and you lose access to your funds, exactly as with any self custodial protocol.
Treat your wallet seed phrase with the same care as your private keys. It is the single source of access to your private balance.
How fast are deposits and payments?
- Deposits confirm in under a second, thanks to Solana.
- Proofs generate in a few seconds on your device.
- Payments settle within a few seconds once the proof is submitted.
Can I deposit any amount?
Yes. Enter anything from 0.01 SOL or 0.1 USDC upward, large or small, round or odd. There are no fixed sizes to pick and no pools to choose between. You enter one number and approve, and ZeroK takes care of the rest.
If amounts are flexible, how does that stay private?
This is the heart of ZeroK. You deposit any amount you like, but when you spend, your funds always leave in fixed, standard denominations, identical to everyone else’s. Because every payment is one of a small set of identical sizes, there is no unusual amount to match and nothing to single you out.
Amounts are the way most privacy tools get broken. ZeroK closes that leak entirely, so the unlinkability comes from the cryptography itself rather than from hoping the pool is busy enough. You get the freedom of any amount with the privacy of uniform spending.
Do I need to save anything after I deposit?
No. Your note is encrypted and stored on chain for you at deposit time, keyed to your wallet. Reconnect the same wallet anywhere and your balance reappears on its own. The only thing to protect is your wallet seed phrase.
Does ZeroK ever hold my funds?
Never. It is a smart contract on Solana. You generate the proof, you choose the recipient, and the contract verifies and releases the funds trustlessly. The protocol cannot access, freeze, or redirect anything.
