I built an open-source chain analysis tool that anyone can use:
https://www.tracey.diy/It requires no payment, no login, and no data you search is ever seen by Tracey’s server.
Everything you search in Tracey is processed directly in your browser.
All of Tracey’s heuristics are public and have clearly described shortcomings. The entire website comes with tooltips explaining to you what each step does. Most of its clustering rules are pulled from the disclosed research papers, some I wrote myself to be more conservative.
I built Tracey for myself, but thought it might be useful to other people as well – especially in light of all the recent thefts of funds. It can’t help you create evidence, but it may help you find some leads on where your money is moving on bitcoin.
Like any chain analysis software, Tracey is basically just a different mempool UI that tries to guess who is sending money to whom.
Tracey detects likely businesss, services or exchanges with a custom heuristic based on batch txs containing at least N outputs going to a minimum of 2 different address types.
It uses the common-input ownership heuristic to cluster wallets that may belong together, and flags coinjoins using the heuristic from mempool[.]space.
Its change heuristic is deliberately conservative, working only on txs with 2 outputs, and it shows you possible peelchains starting from N outputs.
It also has a behavioral heuristic comparing Versions, Locktime, RBF, BIP69, etc, which is honestly probably retarded, but I guess that’s what behavioral heuristics are.
You can search every address via one button on Arkham, to see whether it’s already been publicly attributed.
Next steps for Tracey are collecting and importing already attributed addresses from public court records so they show with sources directly in your trace, and building in wallet explorer for clusters that are already known.
If you think Tracey is useful, please help improve it on gh below – there’s probably a lot of stuff it can do better and might be getting wrong:
