About

The blockchain promises to be a public ledger. In practice it is very hard to read. A wallet with a few years of use has thousands of transfers, dust, tokens that imitate other tokens, and addresses that pass themselves off as ones you have used before. Chainalysis and the other institutional tools can untangle that, at prices only a bank or an exchange can pay. This site does the same, at the scale of one wallet, for free.

The tool

Paste the public address of a wallet and you see its balance today, with the history of up to 500 transactions in one feed. Balances on eleven chains and positions in protocols like Aave. Spam is hidden and counted. Fake tokens and address poisoning are flagged where they sit; never deleted. Counterparties are named when a label exists, and every amount is priced at the day it moved. Everything on screen can be downloaded as a CSV.

What I do

My work is tracing and rebuilding crypto activity. A history rebuilt transaction by transaction and reconciled to the chain, with every gap named: internal transfers the provider does not index, bridges like Across, positions held inside a protocol, tokens that pretend to be another. Then each operation classified under the tax rules of the country in question.

The same method answers AML questions: where the funds came from, which addresses they touched, and whether the story a document tells matches what the chain records. It ends as a file an accountant, a tax authority or a compliance team can take.

Get in touch

The tool is free, and so are questions. If a wallet has you stuck, or you think I could help with something, write to me on LinkedIn.
