Learn Bitcoin Transactions

txray is a toolkit for understanding Bitcoin at every level - from raw bytes to privacy patterns to building better transactions.

What would you like to do?

Choose based on your goal, not the tool.

Parse raw bytes, understand structure, see what's inside

Understand what leaks, why it matters, how analysis works

Apply heuristics, detect change outputs, cluster addresses

Create PSBTs with better privacy and fee control

Installation, first steps, and how the three tools work together.

UTXO model, transaction structure, and privacy fundamentals.

The detection methods: ownership, change, clustering, fingerprinting.

How each tool works under the hood. The math and the papers.

Reference guides for Lens, Sherlock, and Smith.

Hands-on guides: analyze the Pizza transaction, detect CoinJoins, and more.

Most blockchain analysis tools are black boxes. You get a score or a label, but no explanation of why.

txray is different. Every heuristic is documented. Every detection method cites its source. You can see the reasoning, verify it, and learn from it.

This isn't just an analysis tool - it's an educational toolkit for understanding Bitcoin privacy at every level.
