Welcome

Welcome to ZeroK

Private payments on Solana.

ZeroK lets you move SOL without putting your financial life on display. On Solana, every transfer is public: your balance, who you pay, when, and how much. ZeroK gives you a private layer on top, so you decide what the world sees.

Why privacy matters

Solana is fast, cheap, and completely transparent. That transparency cuts both ways:

  • Anyone can look up your wallet and read your entire balance
  • Every payment you make is tied to your identity
  • Merchants, employers, and strangers can trace your activity over time

Privacy is not about hiding. It is about choice. You should decide who sees your money, not the chain.

What ZeroK gives you

  • Fully non custodial. You hold the keys, you generate the proofs, you control your funds at every step.
  • Unlinkable by construction. A proof shows you own a note without revealing which one, so a withdrawal carries no link back to the deposit that funded it. Payments leave in fixed denominations identical to everyone else’s.
  • Gasless for the recipient. The protocol covers the network cost, so the receiving wallet can be brand new and empty.
  • Any amount, SOL or USDC. Deposit from 0.01 SOL or 0.1 USDC. There are no fixed sizes to pick and no pools to choose.
  • Instant. Deposits confirm in well under a second, and proofs generate in seconds.
  • Agent ready. A clean SDK and an MCP server, so autonomous agents can pay privately too.

How it works in 30 seconds

  1. Deposit any amount of SOL or USDC into one shared, shielded vault for that asset.
  2. Pay anyone, anytime. A zero knowledge proof shows you own funds without revealing which, and a relayer covers the gas.
  3. Stay unlinkable. Payments leave in fixed, standard denominations, identical to everyone else’s. With no amount to match, nothing ties your deposit to your spending.

Your balance follows your wallet automatically. Nothing to write down, and nothing to back up beyond the wallet you already have.
