We attribute crypto‑enabled crime to the actors behind it.
chained2u is a blockchain intelligence group that traces ransomware, scams, and sanctions evasion across public ledgers — turning on‑chain evidence into attribution that helps victims recover and supports lawful investigations.
On‑chain forensics, end to end.
We follow the money where it actually lives — the blockchain. Public, permanent, and traceable. Our work converts raw transaction data into clear, sourced attribution that stands up to scrutiny.
Trace & cluster
Follow funds across wallets, bridges, mixers, and exchanges; cluster addresses into real‑world entities.
Attribute actors
Tie on‑chain behavior to ransomware crews, scam networks, and sanctioned entities using corroborated evidence.
Document & report
Produce source‑backed reports with full chain of custody, ready for victims, counsel, and law enforcement.
Independent investigators with on‑chain instincts.
We collaborate with skilled freelancers and researchers. If you can read a blockchain like a paper trail, we'd like to hear from you.
Blockchain analysts
Comfortable with tracing tools, address clustering, and multi‑chain flows.
OSINT investigators
Skilled at linking on‑chain activity to off‑chain identities through open sources.
Crypto‑fluent researchers
Deep understanding of DeFi, mixers, bridges, and laundering typologies.
Data & tooling builders
Engineers who can wrangle ledger data and build the pipelines that scale attribution.
Simple to start, serious about quality.

Intro & scoping
We talk through how you work, what we need, and how engagements are structured.
Pilot a case
Take on a scoped attribution task so we can calibrate on real evidence together.
Ongoing work
Build a steady collaboration on cases that fit your strengths.
Lawful, evidence‑based, and accountable.
Attribution is a serious responsibility. Naming the wrong actor causes real harm, so we hold our work to a clear standard:
- Public data only. We work from open blockchain and open‑source information — no hacking, no unauthorized access, no intrusion.
- Evidence over speculation. Every claim is sourced and corroborated. We don't guess, and we don't manufacture conclusions.
- Support, don't substitute, the law. We assist victims and lawful investigations. We do not engage in vigilantism, doxxing, or retaliation.
- Privacy & care. We handle sensitive findings responsibly and disclose only through appropriate, lawful channels.
