am-i-exposed - Bitcoin Privacy Scanner CLI

What problem does it solve?

This Skill helps you evaluate how much blockchain analysis exposure a Bitcoin transaction, address, wallet, or PSBT reveals, so you can reduce unnecessary privacy leakage.

Core Features & Use Cases

• Transaction privacy scoring (CLI + JSON): Analyze a txid and return a 0–100 score, grade (A+/B/C/D/F), and a structured findings list for CoinJoin/change/entity/entropy signals.
• Address and wallet auditing: Check address reuse and spending patterns, and audit an entire wallet via xpub/zpub/descriptor with gap-limit scanning and wallet hygiene signals.
• Pre-broadcast PSBT analysis (offline): Analyze an unsigned or partially signed PSBT without requiring network access, making it ideal for “check before you sign” workflows.
• Chain graph forensics: Perform multi-hop backward/forward tracing and run entity proximity and taint-related analysis on the discovered graph.
• Boltzmann entropy computation (Rust/WASM): Compute entropy and link probability matrices to quantify ambiguity for multi-input/multi-output transaction structures.

Quick Start

Use the am-i-exposed - Bitcoin Privacy Scanner CLI skill to scan the PSBT file at /tmp/proposed-tx.psbt and return a privacy score and grade in JSON.
