Ethereum researcher Justin Drake urged crypto holders to plan for a possible AI-driven attack on Bitcoin and Ethereum wallet signatures, with his worst-case timeline measured in months rather than years. No practical attack on either network’s wallet keys has been demonstrated, and the timing and feasibility of the risk remain uncertain.
Ethereum researcher Justin Drake urged crypto holders to begin planning for “bunker mode,” warning that artificial intelligence could, in a worst-case scenario, help break the mathematics protecting Bitcoin and Ethereum wallets within months rather than years. No practical attack on either network’s wallet keys has been demonstrated, and Drake’s timeline is a warning, not a confirmed forecast.
Drake called for the industry to calmly plan for “bunker mode” in a post on X on Wednesday, recommending that large holders consider gradually moving assets to fresh addresses whose public keys have never appeared onchain. A wallet’s private key authorizes transactions; its related public key allows the network to verify them. The security assumption is that deriving the private key from the public one requires an impractical amount of computing work.
In Drake’s worst-case scenario, AI could identify a shortcut for solving the relevant mathematical problem, allowing an attacker to recover private keys using ordinary computers. The concern centers on elliptic-curve cryptography, used for wallet signatures. CoinDesk reported that millions of bitcoin are held at addresses with public keys visible onchain. On Ethereum, an account that has sent a transaction has exposed its public key; the same signature system also controls assets such as stablecoins and tokenized funds on the network.
The warning followed OpenAI’s release of 722 mathematical manuscripts generated by an unreleased model tested on about 4,000 research problems, according to the company. OpenAI said some findings had computer-checkable proofs, while others were unverified and could contain errors. CoinDesk reported that an outside researcher reran a computer check on one result within a day and found it held. That result is evidence of progress on a mathematical problem, not evidence that crypto wallet keys have been broken.
Why Wallet Key Exposure Matters
If an attacker could derive private keys from exposed public keys, they could potentially authorize transactions and take control of affected funds. Public-key exposure is not itself proof of vulnerability: current wallet security depends on the computational difficulty of reversing the process, and no working AI method to do so for Bitcoin or Ethereum has been shown.
Drake’s recommendation raises a practical question for holders and network developers: whether to take gradual precautions before there is evidence of an attack, and how to do so without creating new risks. Moving assets can introduce mistakes, expose users to scams, or rely on wallet software that is not secure. The warning is particularly relevant to large holders, but the underlying signature systems also secure many other assets and applications on Ethereum.

AI Security Warnings and Migration Plans
The warning comes amid reports of AI being used to find software vulnerabilities, a distinct risk from breaking cryptographic mathematics. CoinDesk cited earlier demonstrations in which Anthropic researchers used frontier models to write exploits against simulated decentralized-finance contracts. It also reported that an AI-assisted review of Bitcoin software projects surfaced possible flaws, and that developers of BTCPay Server and Core Lightning disclosed vulnerabilities after AI-generated reports. These examples concern software bugs and code review; they do not establish that AI can recover wallet private keys from public keys.
There have also been efforts to prepare for quantum computers, which could threaten some existing cryptographic systems if sufficiently capable machines become available. The Ethereum Foundation has set a December 2029 target for moving the network to quantum-resistant cryptography, according to CoinDesk. Drake’s concern is different: a classical-computer attack enabled by AI could arrive earlier than that plan assumes. CoinDesk also reported that recent AI-assisted work on a calculation related to a future quantum attack still required quantum hardware and addressed only part of the attack.
Ethereum co-founder Vitalik Buterin agreed that AI advances could affect cryptography beyond current wallet signatures. Some proposed quantum-resistant systems use lattice-based mathematics. Buterin wrote that AI could cause “serious hits” to the concrete security of lattices in the next two years. He has expressed a preference for hash-based signatures in Ethereum’s longer-term plans, while acknowledging that those designs also warrant scrutiny.

No Working Key-Breaking Attack Shown
No practical attack on Bitcoin or Ethereum wallet keys has been demonstrated, and CoinDesk said none appeared in the research it reviewed. It remains unclear whether AI will discover a shortcut against the elliptic-curve mathematics used by the networks, how long any such research might take, or whether a theoretical result could be turned into an attack on live wallets.
The OpenAI mathematical manuscripts do not by themselves answer those questions. Some results were unverified, the company said, and the one externally checked result described by CoinDesk concerned a different mathematical problem. Buterin’s concern about lattice-based cryptography is also a warning about possible future effects, not confirmation that those systems have been broken. Drake’s suggested wallet moves would carry their own risks, and the source report does not establish a single migration procedure or timetable for holders.

Research and Wallet Guidance Ahead
Developers, cryptographers, and wallet providers will need to assess whether new AI research changes the security assumptions behind existing signatures and proposed replacements. Holders will be watching for verifiable technical evidence, as distinct from broad predictions, as well as specific guidance from network teams and wallet providers on any safe migration process.
The Ethereum Foundation’s stated target for quantum-resistant changes remains December 2029, while Drake’s warning argues that preparation may need to begin sooner if AI creates a classical-computer threat. The available reporting does not say that either network has adopted a new emergency timetable. Until further research or official guidance clarifies the risk, the prospect of a cryptographic break remains a developing concern rather than a confirmed attack.

Key Questions
Has AI broken Bitcoin or Ethereum wallet keys?
No. The report says no practical attack on either network’s wallet keys has been demonstrated.
What does “bunker mode” mean in Drake’s warning?
Drake used the phrase for preparing against a possible cryptographic attack. He urged large holders to consider a gradual move to fresh addresses whose public keys have never appeared onchain.
Why are exposed public keys part of the concern?
A public key is used to verify a transaction’s authorization. Drake’s concern is that a future AI-assisted method could derive the corresponding private key, but no such method has been shown to work against Bitcoin or Ethereum wallets.
Does OpenAI’s math research prove wallet cryptography is at risk?
No. OpenAI reported mathematical results from an unreleased model, including some that remained unverified. The externally checked result described in the report addressed a different problem and did not demonstrate a way to break wallet signatures.
What should holders watch for next?
They should watch for technical evidence and specific guidance from network developers and wallet providers. The report does not establish an approved migration process or a confirmed deadline for moving funds.
