I reconstruct what happened on-chain — with sealed, reproducible evidence.
I am OnChainSurfer — an independent blockchain forensic investigator. I trace exploits, drains, and laundering, and anchor every claim to a verifiable chain of custody. No trust required.

What I do
Incident reconstruction
I deconstruct how an incident was executed: smart-contract source and bytecode audited in a network-isolated sandbox, the mechanism identified, and the on-chain execution reconstructed transaction by transaction — each step observed and sealed.
Fund tracing & laundering trails
Following proceeds across chains, bridges, DEX swaps and mixers — with visual trace graphs and wallet clustering under documented heuristics. I map what is observable and mark the hard boundaries honestly, never past the evidence.
Attribution & evidence custody
Explorer-label attribution stated as observation, not proof. I build my own attribution database case by case from legally clear public sources — never rented from a vendor.
The standard
My forensic standard is not a style guide — it is an enforced pipeline. Every investigation passes these gates.
Sealed before analyzed
Every artifact is SHA-256 fingerprinted and timestamped into a write-once custody ledger at capture — before any theory is formed. Change a single character and the fingerprint no longer matches: any alteration is mathematically detectable. Sealed records are append-only.
Enforced by code, not policy
An automated gate checks every finding: claims without complete sealed evidence are downgraded to hypotheses, and identity attribution below High confidence is blocked.
Per-finding confidence levels
High confidence requires on-chain verification, at least two independent sealed sources, and third-party reproducibility. Every finding carries its level, visibly.
Zero inherited sources
Pre-existing public write-ups are treated as leads, never as sources. Every fact I assert is independently re-collected and re-sealed under my own chain of custody.
I state what I do not claim
Every report carries an explicit boundary section: floor counts versus totals, hard visibility limits, and exactly what the evidence does not support.
Human-verified, AI-accelerated
AI agents accelerate collection and analysis, but no finding is marked verified without my sign-off. AI suggests, evidence decides, I verify.

About
My practice is built on one principle: affirmative language only for sealed, observable evidence. Interpretations are labeled as hypotheses. Every transaction hash I cite is documented in full — never truncated — with checksummed addresses and UTC timestamps, so every claim is independently reproducible against the public chains.
I answer to the evidence, not to expectation — mine, or anyone else's. Published research is how I prove the standard; private cases run under the same gates, and stay private.
