What is Lost Bitcoin Finder?
The Lost Bitcoin Finder is a comprehensive research tool designed for on-chain analysts to track forgotten wealth within the Bitcoin blockchain. By leveraging multiple API providers, the skill allows users to scan for inactive addresses that haven't moved funds for over five years, identify coins from the earliest blocks (2009-2010), and analyze burned addresses.
This addition to the library of Openclaw Skills provides developers and researchers with the scripts necessary to calculate loss probabilities based on wallet age, transaction history, and balance. It bridges the gap between raw blockchain data and actionable insights regarding the 15-20% of Bitcoin supply estimated to be lost forever.
Lost Bitcoin Finder Use Cases
- Tracking the 'Satoshi era' coins and monitoring ancient addresses for sudden movements.
- Identifying provably unspendable 'burn' addresses to calculate true circulating supply.
- Scoring the probability of lost access for wallets with high balances and long-term inactivity.
- Researching early miner behaviors by analyzing blocks from the first years of Bitcoin's existence.
How Lost Bitcoin Finder Works
- The skill interfaces with public blockchain APIs like Blockchain.com, Mempool.space, and Blockchair to fetch real-time address metadata.
- It processes transaction history to identify the 'First Seen' and 'Last Seen' timestamps for specific UTXOs.
- A logic engine calculates an inactivity score, factoring in how many years have passed since the last outgoing transaction.
- The system checks for 'only-received' patterns, which often indicate a lost private key or a forgotten wallet.
- Results are aggregated into technical reports that categorize addresses by age, balance, and loss probability percentage.
Lost Bitcoin Finder Setup
To use this skill effectively, ensure you have the required binaries and Python environment ready. Openclaw Skills work best when the environment is properly configured.
# Install the required Python requests library
pip install requests
# Ensure python3 and curl are available in your system path
python3 --version
curl --version
Prerequisite: You must have the openclaw-agent running on your machine (Windows or macOS) to facilitate the blockchain analysis and wallet tracking commands.
Lost Bitcoin Finder Data Schema & Taxonomy
The skill organizes its blockchain analysis into structured data outputs to ensure clarity during research. Below is the metadata taxonomy used:
| Attribute | Type | Description |
|---|---|---|
address |
String | The public BTC address being analyzed. |
balance |
Float | The current balance in BTC (converted from Satoshis). |
years_inactive |
Float | Time elapsed since the last transaction in years. |
loss_probability |
Integer | A calculated 0-100% score based on inactivity and transaction patterns. |
tx_count |
Integer | Total number of transactions associated with the address. |
is_burned |
Boolean | Identifies if the address is a known provably unspendable burn address. |
Lost Bitcoin Finder Advanced Features
- Multi-API redundancy: Automatically switches between Mempool, Blockchair, and Blockchain.com to avoid rate limits.
- Loss Probability Scoring: A sophisticated algorithm that weighs inactivity, balance size, and transaction history to predict the likelihood of lost access.
- Ancient Address Awakening Monitor: Real-time tracking scripts designed to detect when a wallet dormant for 10+ years suddenly becomes active.
- Early Block Scraper: Tools to specifically target and filter addresses originating from block heights 1 to 20,000.
