Investor recovers 5 BTC after Anthropic’s Claude unlocks wallet

An investor who posts as @cprkrn regained control of about 5 BTC after using Anthropic’s AI assistant Claude to link an archived wallet file to a partial seed phrase, ending an 11-year lockout.

The investor wrote on X that he lost access after changing the wallet password during a drunken night in college and could not recall the final element required to open the wallet. He reported having two of the three required pieces of information but not the third.

Over more than a decade he ran manual checks and brute-force attempts, the investor reported, cycling through roughly 7 trillion possible password combinations without success.

In mid-May 2026 he uploaded old college notes and files from an archived laptop into Claude. According to the investor, the AI identified an old wallet file, matched it to the incomplete seed phrase and decrypted the wallet, restoring access.

On-chain records show the recovered funds were moved out of the old wallet into an account at Hyperunit soon after access was restored.

The investor wrote that he bought the coins for about $200 at a Starbucks in 2013. At current prices the holdings are valued at roughly $395,000.

He posted the forgotten password on X as ‘lol420fuckthePOLICE!’. He also wrote that he had considered selling the bitcoins if recovered but would wait for a higher price, mentioning a target of $100,000 per coin.

Other users and developers have applied AI tools to try to recover lost access to cryptocurrency wallets by cross-referencing old files, notes and partial memory cues. A user-built live tool has been demonstrated that attempts to search for private keys linked to addresses believed to hold about 1.1 million BTC.

The investor’s post is one of several recent reports of people using AI to match archived data with fragmented memory to regain access to encrypted cryptocurrency wallets.
