Aqua Wallet

MCP server and CLI for managing Bitcoin and Liquid Network wallets through AI assistants like Claude. One seed backs both networks (unified wallet). Agentic AQUA can also operate on the Lightning Network.

Features

• Generate & Import - Create new wallets or import existing seeds
• Unified Wallet - One seed (mnemonic) for Bitcoin and Liquid; unified_balance shows both
• Bitcoin (onchain) - BIP84 wallets, balance and send via btc_* tools (BDK)
• Watch-Only - Import CT descriptors for balance monitoring
• Send & Receive - Full transaction support (L-BTC, BTC, and Liquid assets like USDt)
• Lightning - Send and receive via Lightning using L-BTC
• Assets - Native support for L-BTC, USDt, and all Liquid assets
• Swaps & Pegs - Convert BTC ↔ L-BTC and swap Liquid/cross-chain assets via SideSwap, SideShift, and Changelly
• JAN3 Account - Login, Lightning Address, and WapuPay (pay ARS bank accounts with USDT) via your JAN3 account
• Secure - Encrypted storage, no remote servers for keys

Installation

Quickest way: just ask your AI agent directly:

Install this MCP server: https://pypi.org/project/agentic-aqua/

Python 3.13 required.

Recommended (uv tool install)

If you don't have uv installed:

# macOS/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

Install Agentic AQUA:

uv tool install --python 3.13 agentic-aqua

This creates a permanent agentic-aqua executable. Find its full path with:

which agentic-aqua
# Example: /Users/yourname/.local/bin/agentic-aqua

Configure Claude Desktop (~/.claude/claude_desktop_config.json) using that path:

{
  "mcpServers": {
    "agentic-aqua": {
      "command": "/full/path/to/agentic-aqua",
      "args": []
    }
  }
}

Restart Claude Desktop and you're ready to use Bitcoin and Liquid wallets.

Updating / removing: uv tool upgrade agentic-aqua to update, uv tool uninstall agentic-aqua to remove.

For Developers

Clone and install from source:

git clone https://github.com/jan3dev/agentic-aqua.git
cd agentic-aqua
uv python install 3.13
uv sync --python 3.13

Configure Claude Desktop using the full path to uv (find with which uv):

{
  "mcpServers": {
    "agentic-aqua": {
      "command": "/full/path/to/uv",
      "args": ["run", "--python", "3.13", "--directory", "/absolute/path/to/agentic-aqua", "python", "-m", "aqua.server"]
    }
  }
}

Quick Start

Once connected, you can ask Claude to:

• "Create a new wallet" (creates both Bitcoin and Liquid wallets from one seed)
• "Show my balance" / "What's my Bitcoin balance?"
• "Generate a receive address" (Liquid or Bitcoin)
• "Send 10,000 Sats to bc1..." / "Send 0.001 L-BTC to lq1..."
• "Pay this Lightning invoice: lnbc..."
• "Receive 50,000 Sats via Lightning"
• "Delete my wallet"

Loading seeds safely

Avoid pasting seeds into the chat with your agent. Because it will persist in logs and will be sent to the AI provider, agent transcripts may persist them. The recommended workflow is to use this command that hides the text input:

aqua wallet import-mnemonic --mnemonic-stdin --wallet-name defaultx --network mainnet --password-stdin

The CLI honors these variables out of the box:

Variable	Used by
AQUA_MNEMONIC	wallet import-mnemonic
AQUA_PASSWORD	wallet import-mnemonic, btc send, liquid send, liquid send-asset, lightning send, lightning receive
AQUA_<OPTION>	Any CLI option (Click auto_envvar_prefix="AQUA") — e.g. AQUA_WALLET_NAME=default

If you would rather pipe secrets from a password manager, every secret-bearing command also accepts --mnemonic-stdin / --password-stdin:

pass show crypto/aqua-mnemonic | aqua-cli wallet import-mnemonic --mnemonic-stdin

Tips:

• Never commit .env or secrets.env files (the project's .gitignore already excludes them).
• Prefer set -a; . file; set +a over export $(cat file) — the former tolerates spaces and quotes inside values.
• After importing a wallet, the seed is no longer needed for day-to-day operations; only AQUA_PASSWORD is used to sign transactions.

JAN3 account login

Two login flows, both multi-account (one session per email), ending with a locally saved session:

# Default (free email-OTP)
aqua jan3 login --email [email protected]          # emails an OTP
aqua jan3 verify --email [email protected] --otp 123456

# Fallback (paid captchaless), for accounts that can't use the free flow
aqua jan3 login-start --email [email protected] --wallet-name default --password-stdin
aqua jan3 login-complete --email [email protected] --otp 123456

Once logged in:

aqua jan3 list-sessions
aqua jan3 user-info --email [email protected]
aqua jan3 logout --email [email protected]

Configuration

Default config location: ~/.aqua/config.json

Migrating from aqua-mcp? The config dir moved from ~/.aqua-mcp to ~/.aqua. There is no automatic migration. To carry over your wallets, run once:

mv ~/.aqua-mcp ~/.aqua

{
  "network": "mainnet",
  "default_wallet": "default",
  "electrum_url": null,
  "auto_sync": true
}

Security

Seeds are encrypted at rest using a password (PBKDF2 + Fernet). Without a password, the seed is stored base64-encoded only — use a password for real funds. Note: this password is NOT a BIP39 passphrase; the derived Liquid/Bitcoin keys depend solely on the seed, so the same seed restores identical descriptors in any BIP39-compliant wallet (AQUA, Blockstream App, Jade, etc.).

For maximum security you can:

1. Generate wallet on an air-gapped device
2. Export the CT descriptor
3. Import as watch-only on your daily machine

All private key operations happen locally. Only blockchain sync uses Blockstream's public servers.
