Privacy that fits real life

Everything you need to move money on-chain without broadcasting your finances.

Hidden balances

Your shielded balance and transfer amounts are never visible on public block explorers.

Fast & low-cost

Batched proofs on layer-2 networks keep fees to a few cents per transfer.

Use your existing wallet

Works with the browser and mobile wallets you already trust — nothing new to install.

Compliance built in

Deposit limits, screening and optional view keys keep the pool clean for everyone.

Pay anyone privately

Share a private address or payment link and get paid without revealing your history.

Open source

Contracts and client code are public so anyone can verify how privacy is achieved.

How it works

Three steps to private payments

No new seed phrase, no extension to install.

  1. Connect

    Sign in with the wallet you already use. A private account is derived from your signature.

  2. Shield

    Deposit stablecoins into the shielded pool. Your private balance appears instantly.

  3. Send

    Transfer to any private address. Amounts and counterparties stay hidden on-chain.

  4. Withdraw

    Move funds back to any public address whenever you need them.

Security

Audited, open and non-custodial

Your keys never leave your device.

Every transaction is validated by a zero-knowledge proof generated in your browser. Smart contracts are open source and independently audited, and built-in deposit limits plus optional view keys keep the pool compliant without sacrificing everyday privacy.

  • Non-custodial — only you can move your funds
  • Client-side proving — nothing sensitive is sent to a server
  • Optional view keys for accountants and auditors
