My Story
I got into cryptocurrency in 2017, back when most people had never heard of Bitcoin and the concept of a blockchain was still niche. When the NFT boom hit in 2021, I was already deep enough in the space to understand what was actually happening on-chain. As the market exploded, so did the theft — and I became the person in my network that people came to when their digital assets got stolen. What started as helping people trace a stolen NFT turned into a real discipline: pulling on-chain data, mapping wallet movements, and crossing it with off-chain information like social media accounts to put a face to the theft and help victims understand exactly what happened to their assets.
During that same period, I co-founded an NFT startup that raised $1.8 million to build a marketplace comparable to OpenSea. Running that company gave me deep technical knowledge of how crypto infrastructure actually works — the smart contracts, the on-chain mechanics, the patterns that normal users never see. As the market evolved past NFTs into broader DeFi and large-scale fraud operations, I expanded my investigative capabilities across chains — BTC, ETH, USDT, SOL, BNB — following money wherever it moved, regardless of how many hops or chain bridges stood in the way.
What I do now is a direct extension of what I was doing in 2021 — but the scale and stakes are different. Pig butchering operations, romance scams, and fake investment platforms are stealing life savings, not just JPEGs. Victims come to me after losing $50,000, $200,000, sometimes more. The on-chain trail is always there. My job is to follow it, document it properly, and give people something they can actually take to law enforcement or an attorney. That's Wallet Witness.
What I Do
Wallet Witness is an independent blockchain forensic investigation practice. I trace stolen cryptocurrency using on-chain analysis, transaction graph mapping, wallet clustering, and exchange intelligence — then turn those findings into documentation that victims, attorneys, and law enforcement can actually use.
I don't promise to get your money back. I promise to show you exactly where it went, who controlled it, and what your legal options are. That's the work.

My Values
Honest Expectations
I tell you what's realistic upfront — before you pay anything. If a case isn't worth pursuing, I'll say so.
Victim-First
You've already been deceived once. My job is to give you accurate information, not tell you what you want to hear.
No Guarantees
I'm an investigator. I trace, document, and report. I don't promise recovery — and any service that does is lying.
Full Transparency
You see every step of the investigation. No black box. Detailed findings, documented methodology, clear conclusions.
