A Bitcoin
wallet that had not moved in more than 11 years sent out roughly 5 BTC worth
about $400,000 yesterday (Wednesday), after its pseudonymous owner uploaded the
contents of an old college computer into Anthropic’s Claude and let the AI sift
through more than a gigabyte of files.
The address
14VJySbsKraEJbtwk9ivnr1fXs6QuofuE6
distributed the coins across five transactions on May 13, according to public
blockchain records.
The
recovery, posted on X by an account called Cprkrn, drew more than 11 million
views within hours and prompted reactions from prominent crypto figures
including Castle Island Ventures partner Nic Carter and Base creator Jesse
Pollak.
HOLY FUCKING SHIT OMG CLAUDE JUST CRACKED THIS SHIT, THANK YOU @AnthropicAI THANK YOU @DarioAmodei NAMING MY KID AFTER YOU 😍https://t.co/gObNirRDpS https://t.co/ByTdIM4d20 pic.twitter.com/xB5LUJb6Pe

The case
sits inside a broader trend of large language model deployment across crypto
infrastructure, following work by Revolut engineers who built an
AI-driven trading workflow with Claude in 30 minutes earlier this year.
What Claude Actually Did
Despite the
“OMG Claude just cracked this shit” framing in the original tweet,
the AI did not break Bitcoin’s encryption. Cprkrn
told Cointelegraph in a follow-up interview that he had already located a
handwritten mnemonic in an old notebook before turning to Claude.
The AI then
searched two Macs, two external hard drives, an Apple Notes export, an iCloud
Mail inbox, a Gmail inbox and X direct messages, totaling more than a gigabyte
of unstructured data, according to the user’s account.
I tried like 7 trillion passwords lmfao
Found this old pneumonic a few weeks ago that ended up being the old password before I changed it
Thought I was screwed
Last ditch effort dumped my whole college computer into Claude
It found an OLD wallet file that the pneumonic…

On the
college computer, Claude located a wallet backup file from December 2019 that
predated a password change Cprkrn had made on blockchain.info, and the mnemonic
decrypted that older file.
Claude also
identified a logic detail in the open-source recovery tool BTCRecover, which
concatenates a sharedKey value with the user password during decryption.
Total
compute spend came to roughly $15, according to a summary the model produced.
The recovered password, Cprkrn later disclosed publicly, was
“lol420fuckthePOLICE!*:)”.
Wallet Recovery Industry
Faces a New Cost Curve
Commercial
recovery services have for years charged premium prices for the technical
expertise needed to handle legacy Bitcoin Core wallets. Cprkrn said he had
spent roughly $250 per failed attempt at such services before turning to AI.
Firms
including Wallet Recovery Services and KeychainX market brute-force password
recovery and typically take percentage cuts of recovered funds.
The case
fits a wider thread of AI deployment across crypto-adjacent functions. ATFX
partnered with data firm KX in late 2025 to deploy an AI-driven MCP server for
real-time trading data, while LSEG connected its market data feeds to ChatGPT
in December 2025.
Bitget
Wallet launched its Smart Money feature earlier, tracking high-performing
addresses with AI to surface trading signals.
In this
case, the user worked through Claude’s consumer interface with standard file
uploads and tool use, not a purpose-built API integration or agent-ready exchange architecture.
If the
account is accurate, the same workflow could in principle be replicated by any
holder of a legacy wallet with surviving file backups.
The Dormant Supply
Question Returns
Industry
estimates of inaccessible Bitcoin vary widely. Cointelegraph cited reports
putting between 2.3 million and 4 million BTC as unrecoverable, or roughly 11%
to 19% of the 21 million maximum supply.
Glassnode
data shows about 34% of circulating supply, more than 7 million coins, sits in
wallets that have not transacted in years. A 2020 Chainalysis estimate put
confirmed lost coins at approximately 3.7 million.
Fidelity
Digital Assets, citing Glassnode, reported in 2025 that more than 566 BTC per
day were aging into the “ancient” category of coins untouched for 10
years or more. Miners produce only 450 BTC per day following the April 2024
halving.
The
differential between dormant accumulation and new issuance has been cited as
structural support for Bitcoin prices, on the assumption ancient coins
represent lost supply.
There is no
evidence the Cprkrn case meaningfully shifts those estimates. But the
demonstration that consumer AI tools can compress recovery costs from
professional service rates to $15 changes the cost-benefit math for holders of
forgotten wallets.
Forensics or Cracking?
Experts Push Back
Wallet
recovery experts told
Decrypt the screenshots posted by Cprkrn showed file forensics, not
cryptographic work.
“Claude’s
likely role was sorting through large amounts of historical data and
identifying clues tied to older wallet credentials or password formats,”
one expert told the outlet, adding that the case is “not so much a
password cracking thing as it is a forensics sorting.”
The
skepticism extended to Reddit. “Claude didn’t do anything other than
search his files,” user
MeteorSwarmGallifrey wrote in the technology subreddit, arguing the model
had not done anything “groundbreaking.”
Other
commenters defended the use of AI for forensic triage across years of
unstructured personal data, noting that knowledge of how older Bitcoin Core
wallet files persist as .bak backups is non-obvious to non-specialists.
