Nockchain Wallet

Key Management

Generate New Key Pair

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

Import Private Key

# Import keys from a jammed file
nockchain-wallet import-keys --input path/to/keys.jam

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

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.

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 ./test-leader/nockchain.sock <command>

# Example: broadcasting a transaction
nockchain-wallet --nockchain-socket ./test-leader/nockchain.sock make-tx --draft my_draft

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

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.
