Nockchain Wallet

Setup

Generate New Key Pair

# Generate a new key pair with random entropy
nockchain-wallet keygen

Importing and Exporting Keys

The wallet supports importing and exporting keys:

# Export all wallet keys to a file (default: keys.export)
nockchain-wallet export-keys

# Import keys from the exported file
nockchain-wallet import-keys --input keys.export

# Import a master public key and chain code
nockchain-wallet import-master-pubkey --key <base58-key> --chain-code <base58-chain-code>

The exported keys file contains all wallet keys as a jam file that can be imported on another instance.

Can be used for:

• Backing up your wallet
• Migrating to a new device
• Sharing public keys with other users

Connecting to Nockchain

The wallet needs to connect to a running nockchain instance to perform operations like checking balances, broadcasting transactions, etc.

# Connect to nockchain using a Unix domain socket
nockchain-wallet --nockchain-socket ./nockchain.sock <command>

Note: Make sure nockchain is running and the socket path matches your nockchain configuration.

Advanced Options

Generate Master Private Key from Seed Phrase

nockchain-wallet gen-master-privkey --seedphrase "your seed phrase here"

Creates a master private key deterministically from a BIP39-style seed phrase.

Generate Master Public Key from Private Key

nockchain-wallet gen-master-pubkey --master-privkey <private-key>

Derives the master public key from a master private key.

Derive Child Key

nockchain-wallet derive-child --key-type <pub|priv> --index <0-255>

Derives a child public or private key at the given index from the current master key.

Listing Notes

List All Notes

nockchain-wallet list-notes

Displays all notes (UTXOs) currently managed by the wallet, sorted by assets.

List Notes by Public Key

nockchain-wallet list-notes-by-pubkey --pubkey <public-key>

Shows only the notes associated with the specified public key. Useful for filtering wallet contents by address or for multisig scenarios.

Transaction Creation

Components of transaction creation

1. Seeds: Define where funds are going and how much
2. Inputs: Specify which notes (UTXOs) to spend
3. Draft: Combine inputs into a complete transaction
4. Sign: Authorize the transaction with private keys
5. Make Transaction: Create the final transaction for broadcasting

What is a draft?

A draft represents a transaction that is being prepared for submission to the network. It is a collection of partially assembled seeds and inputs that can be persisted to disk and later signed and submitted.

Create a Draft

# Create a draft using simple-spend
nockchain-wallet simple-spend \
  --names "[first1 last1],[first2 last2]" \
  --recipients "[1 pk1],[2 pk2,pk3]" \
  --gifts "100,200" \
  --fee 10

Make Transaction from Draft

# Sign the transaction
nockchain-wallet sign-tx --draft path/to/draft.draft

# Make and broadcast the signed transaction
nockchain-wallet make-tx --draft path/to/draft.draft

Note: The draft file will be saved in ./drafts/ directory with a .draft extension.
