Cocod - Cashu Wallet CLI

Cocod is a Cashu wallet for managing ecash tokens and making Bitcoin/Lightning payments. It uses the Cashu protocol for privacy-preserving ecash transactions.

What is Cashu?

Cashu is a Chaumian ecash protocol that lets you hold and transfer Bitcoin-backed tokens privately. It enables unlinkable transactions using blind signatures.

Installation

# Install cocod CLI
bun install -g cocod

Quick Start

# Initialize your wallet (generates mnemonic automatically)
cocod init

# Or with a custom mint
cocod init --mint-url https://mint.example.com

# Check balance
cocod balance

Commands

Core Wallet

# Check daemon and wallet status
cocod status

# Initialize wallet with optional mnemonic
cocod init [mnemonic] [--passphrase <passphrase>] [--mint-url <url>]

# Unlock encrypted wallet (only required when initialised with passphrase)
cocod unlock <passphrase>

# Get wallet balance
cocod balance

# Test daemon connection
cocod ping

Receiving Payments

# Receive Cashu token
cocod receive cashu <token>

# Create Lightning invoice to receive
cocod receive bolt11 <amount> [--mint-url <url>]

Sending Payments

# Create Cashu token to send to someone
cocod send cashu <amount> [--mint-url <url>]

# Pay a Lightning invoice
cocod send bolt11 <invoice> [--mint-url <url>]

Mints

# Add a mint URL
cocod mints add <url>

# List configured mints
cocod mints list

# Get mint information
cocod mints info <url>

Lightning Address (NPC)

Lightning Addresses are email-style identifiers (like name@npubx.cash) that let others pay you over Lightning. If you have not purchased a username, NPC provides a free address from your Nostr npub; purchasing a username gives you a human-readable handle. Buying a username is a two-step flow so you can review the required sats before confirming payment.

# Get your NPC Lightning Address
cocod npc address

# Reserve/buy an NPC username (two-step)
cocod npc username <name>
cocod npc username <name> --confirm

History

# View wallet history
cocod history

# With pagination
cocod history --offset 0 --limit 20

# Watch for real-time updates
cocod history --watch

# Limit with watch
cocod history --limit 50 --watch

Daemon Control

# Start the background daemon (started automatically when not running when required)
cocod daemon

# Stop the daemon
cocod stop

Examples

Initialize with encryption:

cocod init --passphrase "my-secret"

Receive via Lightning:

cocod receive bolt11 5000
# Returns: lnbc50u1... (share this invoice to receive)

Pay a Lightning invoice:

cocod send bolt11 lnbc100u1p3w7j3...

Send Cashu to a friend:
