A CLI tool to inspect SideSwap UTXOs

ssutxos is a Python command-line interface (CLI) tool for interacting with Liquid wallets. It allows users to list UTXOs (unspent transaction outputs) for a wallet derived from a BIP39 mnemonic, save them in JSON format, and compare different UTXO sets by exploring transaction descendants via the Blockstream Esplora API.

---

✨ Features

• Display the version of the CLI.
• List Liquid UTXOs for a wallet from a mnemonic.
• Support for both mainnet and testnet Liquid networks.
• Save UTXOs as a JSON file for further processing.
• Compare two UTXO sets and trace descendant relationships via transaction graph traversal.

List UTXOs

ssutxos list --mnemonic "your twelve or twenty-four word mnemonic" --network mainnet

Options

| Option | Description | Default | | -------------------- | -------------------------------------- | ------- | | --mnemonic / -mn | BIP39 mnemonic (12 or 24 words) | None | | --network | Liquid network: mainnet or testnet | mainnet | | --output / -o | Output JSON file | utxos.json|

Example

ssutxos list --mnemonic/-mn "abandon abandon abandon ..." --network testnet --output/-o utxos.json

This will output UTXOs in a JSON format like:

[
  {
    "txid": "abc123...",
    "vout": 0,
    "asset": "L-BTC",
    "amount": 0.1234,
    "address": "ex1q..."
  }
]

Additionally, it saves the UTXOs to a file named utxos.json.

Compare Two UTXO Sets

You can compare UTXOs from two JSON files.

ssutxos compare run utxos1.json utxos2.json --sleep-ms 100

• utxos1.json → the target UTXOs
• utxos2.json → starting UTXOs (the exploration frontier)
• --sleep-ms → delay between API requests (default: 100 ms, helps avoid rate limits)

Supported JSON Formats

Both wrapped and flat formats are accepted:

Wrapped

{
  "utxos": [
    { "txid": "abc123...", "vout": 0, "asset": "L-BTC", "amount": 0.0001, "address": "lq1..." }
  ]
}

Flat

[
  { "txid": "abc123...", "vout": 0, "asset": "L-BTC", "amount": 0.0001, "address": "lq1..." }
]

Example Run

Starting from utxos1.json utxos.
Searching in utxos2.json-derived descendants.
Targets: 2; Start frontier: 2
API base: https://blockstream.info/liquid/api; sleep: 100 ms
Searching hop 0: new frontier size 2
Searching hop 1: new frontier size 5
FOUND a match at hop 2: Outpoint(txid=abc123..., vout=1)
Stopped by user. Total matches found: 1

⚠️ Notes

• Ensure you have internet access to query the Blockstream Esplora Liquid API (https://blockstream.info/liquid/api).
• Exploration runs until you press Ctrl-C. Large graphs may consume significant resources.
• Only L-BTC (Liquid Bitcoin) is supported for balance calculation.
