Welcome to ZK Send

ZK Send is a Telegram bot that lets you send SOL privately using zero-knowledge proofs. Your funds are secured by Privy’s trusted execution environment, and transfers are made private through Privacy Cash.

​
Quick start

1

Start the bot

Open Telegram and send /start to the ZK Send bot. This initializes your account and creates or restores your Privy wallet.
2

Set up your wallet

  • /start lets first-time users choose between keeping the freshly generated embedded wallet or importing an existing key inline
  • You can revisit /import later to add more wallets
3

Check your balance

Run /balance to see your current SOL balance.
4

Send SOL privately

Use /send to transfer SOL. The bot handles the entire privacy flow automatically.

​
Key concepts

​
Private transfers

When you send SOL via /send, the bot:
  1. Deposits your SOL into Privacy Cash
  2. Generates a zero-knowledge proof
  3. Withdraws to your recipient
This makes the transfer private—the recipient and amount are hidden on-chain.

​
Wallet custody

  • Privy manages your keys: Private keys are stored in Privy’s TEE (Trusted Execution Environment)
  • Bot has signer permissions only: The bot can request signatures but never sees your raw keys
  • You can export: Embedded wallets can be exported if needed

​
Multi-wallet support

You can link multiple wallets to your account:
  • View all wallets with /wallets
  • Switch the active wallet anytime
  • Each wallet is managed independently

​
Common workflows

​
Security best practices

  • Never share private keys: The bot auto-deletes imported keys, but be careful
  • Verify recipient addresses: Double-check addresses before sending
  • Use secure devices: Access the bot from trusted devices only
  • Monitor your balance: Check /balance regularly to catch unauthorized activity
