A Bitcoin holder known on X as @cprkrn successfully recovered approximately 5 BTC (worth between $400,000 and $500,000) from a wallet he had been locked out of for over 11 years. The recovery, announced on May 13, 2026, was achieved using Anthropic's Claude AI, which solved a technical problem that had resisted all previous attempts.
Background: A Drunken Password Change
The wallet, tied to address 14VJySbsKraEJbtwk9ivnr1fXs6QuofuE6, had been inaccessible since roughly 2014 or 2015. While in college, @cprkrn changed the wallet's password while intoxicated and forgot the new one. He still had an old mnemonic phrase, “lol420fu**thePOLICE!*:)”, but it no longer opened the current wallet file due to subsequent updates.
He spent roughly $250 on professional recovery attempts over the years and tried what he described as “like 7 trillion passwords” before giving up on conventional methods. He waited until Bitcoin crossed $100,000 to seriously attempt recovery again. By May 13, 2026, the price had pulled back to the $80,000–$82,000 range, but the funds were still worth pursuing.
Claude AI's Breakthrough: Fixing btcrecover Bug
@cprkrn decided to upload the entire contents of his old college computer—including files, notebooks, and backups—into Claude. The AI located an older wallet file that predated the password change and identified why the mnemonic no longer worked on the current file.
The technical problem came down to how the password was being processed. The btcrecover tool, a widely used open-source Bitcoin wallet recovery utility, was concatenating a shared key with the password in an incorrect order. Claude identified the bug, corrected the decryption logic, ran the process, and extracted the private keys in Wallet Import Format (WIF).
The recovered keys matched the target address. Claude's output, which @cprkrn screenshotted and posted to X, read: “PRIVATE KEYS DECRYPTED! WE GOT IT!!! THE 5 BTC IS YOURS!” The wallet app screenshot that followed showed an imported legacy P2PKH wallet with the full 5 BTC balance and pending outbound transactions.
Community Reaction and Implications
@cprkrn summarized the method for others: “Just mega dump all of your computers and notebooks into Claude.” The X thread drew more than 414,000 views and approximately 1,900 likes within hours. Responses came from across the crypto community, including Nic Carter, Jesse Pollak, Laura Shin, and @bitcoinarchive. Some called it a lifesaver. A smaller number raised questions about the security implications of AI systems working with encrypted wallet files, though the recovery relied on the user already possessing the correct, older password.
What Claude did was not a brute-force attack. It parsed files, understood the structure of legacy wallet software, debugged an existing tool, and ran the corrected process. The wallet format involved was P2PKH, a legacy type common in early Bitcoin use before 2015.
@cprkrn closed the thread by thanking Anthropic and its CEO, Dario Amodei, directly: “Naming my kid after you.” The funds—received on April 1, 2015, totaling 5 BTC—sat untouched until they were swept out the same day the recovery was completed.
This case demonstrates that AI can handle niche technical tasks that formal recovery services cannot, raising hope for holders with old wallets. It also highlights the growing role of advanced AI in solving legacy crypto problems, though security concerns around AI access to encrypted material remain a topic of debate.
