How to Transfer Privately

Transferring tokens privately in zDoge allows you to send tokens between shielded addresses without revealing sender, recipient, or amount on-chain.

Before You Start​

Ensure you have:

  • Shielded balance (at least one shielded note)
  • Recipient's shielded address (zdoge:...)
  • Small amount of DOGE for gas (if not using relayer)

Step-by-Step Guide​

1. Navigate to Send​

Go to the Send section in the dashboard.

2. Select Token​

Choose the token you want to send from the dropdown.

3. Enter Recipient Address​

Enter the recipient's shielded address. It should start with zdoge::

zdoge:1692ef053331b2a1369a0ae03a5f38156e6c31bd2a9bb16e9c2dfdb237c8037a
Getting Shielded Address

The recipient can find their shielded address in the Receive section of their wallet.

4. Enter Amount​

Enter the amount you want to send. The system will:

  • Automatically select notes to spend
  • Calculate change (if needed)
  • Show the relayer fee (if using relayer)
Automatic Note Selection

The system automatically selects the best notes to spend, similar to Bitcoin's UTXO model. You don't need to manually choose notes.

5. Review Transaction​

Before confirming, review:

  • Amount to send: What recipient will receive
  • Relayer fee: Fee for gasless transaction (if using relayer)
  • Change: Amount returned to you (if any)
  • Total cost: Amount deducted from your shielded balance

6. Generate Proof​

Click "Send" to begin:

  1. Generating Proof (30-60 seconds)

    • A zero-knowledge proof is generated in your browser
    • This proves you own valid notes without revealing which ones
    • Encrypted memo is created for recipient

  2. Submitting Transaction

    • The proof is submitted to the blockchain
    • Transaction is processed (directly or via relayer)

  3. Confirmation

    • You'll see a success message with the transaction hash
    • Change note (if any) is automatically added to your wallet

Auto-Discovery for Recipient​

The recipient doesn't need to do anything! Their wallet will:

  1. Scan for new transfers automatically
  2. Decrypt the memo using their spending key
  3. Add the note to their wallet
  4. Update balance automatically
  5. Show notification when received
Privacy

The recipient's wallet automatically discovers incoming transfers via encrypted memos. No manual note sharing required!

Understanding Encrypted Memos​

Each transfer includes an encrypted memo containing:

  • Note details (amount, token, secret, blinding)
  • Ephemeral public key
  • Encrypted with recipient's shielded address

Only the recipient can decrypt the memo using their spending key.

Fee Structure​

When using the relayer (gasless transactions):

Fee TypeAmountPurpose
Relayer Fee~0.5%Gas costs & service
Direct Transactions

You can also submit transactions directly (without relayer) to avoid fees, but you'll need DOGE for gas.

Privacy Features​

Private transfers hide:

  • Sender identity - No on-chain link to your address
  • Recipient identity - Recipient address is hidden
  • Transaction amount - Amount is encrypted
  • Transaction link - No way to link sender and recipient

Troubleshooting​

"Insufficient shielded balance"​

You don't have enough shielded tokens. Shield more tokens first.

"Invalid recipient address"​

Ensure the address:

  • Starts with zdoge:
  • Is a valid shielded address format
  • Belongs to the recipient

"Proof generation failed"​

  • Refresh the page and try again
  • Ensure you're using a modern browser
  • Check that JavaScript is enabled
  • Try a smaller amount

"Transaction failed"​

  • Check your gas balance (if not using relayer)
  • Ensure relayer has sufficient balance (if using relayer)
  • Try again after a few minutes

Privacy Best Practices​

  1. Use fresh recipient addresses - Don't reuse addresses
  2. Vary amounts - Don't create patterns
  3. Wait between transactions - Don't rush
  4. Use VPN or Tor - Additional privacy layer
  5. Don't link transactions - Keep transfers independent
