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.

Lightning Address (NPC)

Lightning Addresses are email-style identifiers (like [e-mail]) 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

Daemon Control

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

# Stop the daemon
