Why This Exists
The Bitcoin privacy tools the community relied on are gone. This is the replacement.
The Gap
In April 2024, OXT.me and KYCP.org went offline following the arrest of the Samourai Wallet developers. OXT was the gold standard for Boltzmann entropy analysis. KYCP made CoinJoin privacy assessment accessible to ordinary users. Both are gone.
Chain surveillance firms like Chainalysis, Elliptic, and Crystal still have their tools. They analyze every transaction on the Bitcoin blockchain. They cluster addresses, trace fund flows, and flag wallets.
But as of that moment, ordinary Bitcoin users had no way to see what these firms could infer about their own transactions. The asymmetry was total: they could see everything about you, and you could see nothing about yourself.
am-i.exposed was built to close that gap.
What It Does
Paste any Bitcoin address, transaction ID, xpub/descriptor, or unsigned PSBT. The tool runs the same techniques chain analysis firms use and shows exactly what they can infer - with a privacy score from 0 to 100, detailed findings, and actionable recommendations.
31 Privacy Heuristics
Round amounts, change detection, CIOH, CoinJoin patterns (Whirlpool, WabiSabi, JoinMarket), wallet fingerprinting, script analysis, timing, and more.
Multi-Hop Chain Tracing
Backward and forward transaction tracing, entity proximity detection, taint analysis, UTXO clustering, peel chain tracing, and temporal pattern analysis.
Entity Detection
364 known entities across 30M+ addresses - exchanges, darknet markets, mixers, gambling, mining pools, scams, and payment services. OFAC-list coverage included.
Boltzmann Entropy (WASM)
Full link probability matrix computed on-device via Rust/WebAssembly. Real entropy calculation, not estimation - the same math OXT.me used, running locally using all threads, with turbo paths for JoinMarket and more.
Wallet Audit
Paste an xpub or output descriptor. BIP44/49/84/86 derivation. Aggregate privacy assessment across all derived addresses - reuse, UTXO hygiene, spending patterns.
PSBT Pre-Broadcast Check
Analyze an unsigned transaction before signing. Catch round amounts, script mismatches, and fingerprinting issues while they can still be fixed.
Interactive Visualizations
Transaction flow diagrams, Boltzmann heatmaps, interactive graph explorer, taint path diagrams, cluster timelines, CoinJoin structure breakdowns, and more.
5 Languages
Full interface translation in English, Spanish, Portuguese, German, and French. Community contributions welcome.
Smart Local Cache
Confirmed transactions, outspends, and analysis results are cached in IndexedDB across sessions. Repeat scans are instant, API requests are minimized, and fewer queries leave the browser.
Self-Hostable
Available as an Umbrel app connecting to your own Bitcoin node. Or point it at any custom mempool.space instance for zero third-party exposure.
Design Principles
100% Client-Side
All analysis runs in your browser. No server processes or stores your data.
No Tracking
No analytics, no cookies, no fingerprinting. What you scan is never sent to any analytics or tracking service.
Open Source
Every line of code is auditable. MIT licensed. Fork it, self-host it, improve it.
Free Forever
No paywalls, no premium tiers, no token. Bitcoin privacy tools should be accessible to everyone.
Value for Value
If it provides value, send value back via Lightning. No pressure, no guilt, no accounts.
Built By
am-i.exposed is built and maintained by Copexit and Arkad (@multicripto). Privacy is a right, not a feature. This project has no VC funding, no token, and no business model beyond Value for Value.
Get Involved
This is an open-source project and contributions are welcome. Whether it's fixing a bug, improving a heuristic, adding a translation, or just starring the repo - every bit helps.
