Archon Cashu - DID-Integrated Ecash

Cashu ecash operations using your Archon DID for P2PK-locked tokens. Send sats that only the recipient's DID can unlock.

Prerequisites

• Archon identity configured (~/.archon.env)
• Cashu CLI installed (pip install cashu or similar)
• Config file at ~/.config/archon/cashu.env (or ARCHON_CASHU_CONFIG)

Configuration

./scripts/cashu/config.sh

Sets up Cashu wallet and optional LNBITS integration.

Operations

Check Balance

./scripts/cashu/balance.sh

Send Tokens (Unlocked)

./scripts/cashu/send-unlocked.sh <amount>

Returns a Cashu token anyone can redeem.

Send Tokens (DID-Locked)

./scripts/cashu/send.sh <amount> <recipient-did>

Locks tokens to recipient's DID-derived pubkey (P2PK). Only they can unlock.

Receive Tokens

./scripts/cashu/receive.sh <token>

Mint Tokens (Lightning)

./scripts/cashu/mint.sh <amount>

Creates Lightning invoice to mint new tokens.

Lock/Unlock Tokens

./scripts/cashu/lock.sh <amount> <did>

Backup Wallet to Vault

./scripts/cashu/backup.sh [vault-did]

npub.cash Setup

./scripts/cashu/npub-cash-setup.sh

Configure npub.cash integration for Nostr zaps.

Security Notes

1. Wallet location: ~/.cashu by default (configurable via CASHU_WALLET_DIR)

2. P2PK locking: DID-locked tokens use your DID's secp256k1 key for cryptographic locking

3. LNBITS integration: Optional — for auto-paying invoices during mint operations
