- Trace cryptocurrency addresses and transactions on public blockchains using block explorers including Etherscan, Blockchair, mempool.space and Blockscout. Use when following a Bitcoin or Ethereum wallet, investigating where a ransom or scam payment went, or checking an address against sanctions listings.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Follow the Crypto Public chains are pseudonymous, not anonymous. Every transfer is permanently visible to anyone; what's missing is the mapping from address to human. So the whole game is attribution, and attribution almost always happens at an off-ramp — the point where value converts to [человек] through a service that collected identity documents. Everything between the crime and the off-ramp is just plumbing you have to follow. The beginner error is treating a clustering heuristic's output as fact. "These addresses belong to the same entity" is a probabilistic inference with known failure modes, and commercial attribution labels are proprietary guesses you cannot audit. Trace confidently; attribute carefully. ## Triage: what are you holding? | You have | Start with | Why | |---|---|---| | An address string | Identify the chain from its shape, then a block explorer | Format alone usually determines chain and script type — see the [address-format table](reference/address-formats.md) | | A transaction hash | Explorer's transaction view | Gives you both sides, the fee, the block time, and any contract calls | …

How to install
mdr add tonydzi/second-brain-starter-kit/follow-the-crypto@sha256:974b52193c53ee94The line at the top of this page pins the label git:20261020.402f6b7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
