am-i-exposed - Bitcoin Privacy Scanner CLI

You score Bitcoin privacy exposure by analyzing an unsigned PSBT locally to receive a 0-100 score, letter grade, and structured findings without requiring network access. This pre-broadcast check identifies CoinJoin, change, and entropy signals.

You can audit wallet privacy using an xpub, zpub, or output descriptor. The analysis performs gap-limit scanning to check address reuse and spending patterns, producing wallet hygiene signals to quantify your blockchain analysis exposure.

Boltzmann entropy computation for Bitcoin transaction analysis calculates entropy and link probability matrices to quantify ambiguity for multi-input and multi-output transaction structures. This reveals how easily chain tracing can deduce input-output mappings.

You trace chain graph forensics for a known Bitcoin txid by performing multi-hop backward and forward tracing with optional mempool API access. The analysis runs entity proximity and taint-related analysis on the discovered graph to return a privacy score.

The Bitcoin privacy scanner does not require internet access to analyze PSBTs. It uses local deterministic analysis for offline pre-broadcast checks, with optional mempool API access only needed to fetch blockchain context for known txids.

You can get JSON output from a Bitcoin transaction privacy score for agent workflows. The scanner supports JSON output with consistent schema fields, returning the 0-100 score, grade, and findings list for seamless downstream processing.
