Private Transfers

Send and receive SOL privately using zero-knowledge proofs powered by Privacy Cash protocol

What is Privacy Cash?

Privacy Cash is a zero-knowledge protocol on Solana that enables completely private transfers of SOL and SPL tokens. When you deposit funds into Privacy Cash, they enter a privacy pool where the connection between sender and receiver is cryptographically broken.

Unlike regular blockchain transactions where anyone can see sender, receiver, and amount, Privacy Cash uses ZK-SNARK proofs to prove ownership without revealing any identifying information on-chain.

How It Works

1. Deposit

Deposit SOL into the privacy pool. A zero-knowledge proof is generated proving you own the funds, and an encrypted UTXO is created on-chain that only you can decrypt.

2. Private Balance

Your funds are now in a private balance that only you can see and access. The balance is stored as encrypted UTXOs on-chain with no link to your wallet address.

3. Check Balance

At any time, you can check your private balance by decrypting your UTXOs using your private key. This happens entirely client-side - no one else can see your balance.

4. Withdraw

Withdraw to any address you choose. The on-chain transaction shows no connection to your original deposit - maximum privacy guaranteed by zero-knowledge proofs.

Privacy Best Practices

  • •Use clean wallets: Always withdraw to fresh, never-used wallet addresses
  • •Wait before withdrawing: Wait at least 24 hours between deposit and withdrawal
  • •Use round amounts: Deposit common amounts (1 SOL, 0.5 SOL) to increase anonymity set
  • •Split withdrawals: Split large amounts into multiple smaller withdrawals over time
  • •Vary amounts: Don't withdraw the exact same amount you deposited

Security Notice

Your private key never leaves your browser. All encryption and decryption happens client-side. ShadeSwap never stores or transmits your private key to any server.

However, be aware that Privacy Cash uses a relayer system. The relayer screens wallets through CipherOwl for malicious activity before processing deposits.

Always verify you are on the correct website (shadeswap.io) before entering any sensitive information.
