Cashu Wallet

Cashu Wallet is a lightweight, privacy-focused Bitcoin wallet powered by Cashu ecash. It allows you to send and receive payments instantly using the Lightning Network or by exchanging ecash tokens directly.

🌟 Key Features

  • Bitcoin over Lightning: Seamlessly send and receive Lightning payments.
  • Cashu Ecash: Privacy-preserving ecash tokens.
  • Multi-Mint Support: Connect to multiple mints to diversify risk or support different currencies (sats, usd, eur, etc., depending on the mint).

📦 Installation & Setup

The wallet is a Node.js CLI application located in this directory.

  1. Install Dependencies:

``bash cd cli npm install ``

  1. Create Alias (Optional but Recommended):

To make commands easier to run, you can create an alias: ``bash alias cashu='node cli/wallet.mjs' ``

🚀 Usage Guide

All commands can be run using node cli/wallet.mjs <command> (or cashu <command> if aliased).

1. Managing Mints

Before you can do anything, you need to trust a Mint. A mint exchanges Bitcoin (Lightning) for ecash tokens.

  • List Mints: View connected mints and their status.

``bash node cli/wallet.mjs mints ``

  • Add a Mint: connect to a new mint URL.

``bash node cli/wallet.mjs add-mint https://mint.url # Example (Testnut): node cli/wallet.mjs add-mint https://testnut.cashu.space ``

2. Receiving Money (In)

  • Via Lightning (Deposit): Create a Lightning invoice to swap BTC for ecash.

``bash # Usage: invoice <amount> [mint_url] node cli/wallet.mjs invoice 1000 `` This command will generate an invoice and wait for payment. Once paid, it automatically mints the tokens.

  • Via Ecash Token: Receive a Cashu token string sent by someone else.

``bash # Usage: receive <token> node cli/wallet.mjs receive "cashuA..." ``

3. Sending Money (Out)

  • Via Lightning (Pay Invoice): Pay a BOLT11 Lightning invoice using your ecash balance.

``bash # Usage: pay-invoice <bolt11invoice> [minturl] node cli/wallet.mjs pay-invoice lnbc10u... ``

  • Via Ecash Token: Generate a token to send to someone else off-chain.

``bash # Usage: send <amount> [mint_url] node cli/wallet.mjs send 500 ` Output: A cashuA...` token string that you can share.

4. Wallet Management

  • Check Balance: See your total balance across all mints.

``bash node cli/wallet.mjs balance ``

  • Transaction History: View past deposits, withdrawals, and transfers.

``bash node cli/wallet.mjs history ``

  • Check Pending Invoice: If you created an invoice but closed the CLI before it confirmed, check it manually.

``bash # Usage: check-invoice <quoteid> [minturl] node cli/wallet.mjs check-invoice "quoteidhere" ``

  • Restore Wallet: Recover funds from a specific mint using your seed (stored in ~/.cashu-wallet/seed.txt).

``bash node cli/wallet.mjs restore https://mint.url ``

🛠️ Troubleshooting

  • Logs & Data: Data is stored in ~/.cashu-wallet/wallet.db.
