Crypto holders gain a clear defensive playbook: migrating funds to fresh wallet addresses that have never broadcast a public key can blunt the next generation of AI-powered attacks on wallet cryptography, before any move becomes urgent.
Two Ethereum core researchers have warned that rapid gains in AI-driven mathematics could undermine the elliptic curve digital signature algorithm (ECDSA) used to secure cryptocurrency wallets, potentially on a shorter timeline than quantum computers. They are calling on large holders to begin a careful, controlled migration of funds to new addresses whose public keys have not been exposed, a practice referred to in the community as going into crypto “bunker mode.”
Why AI math, not quantum, is the near-term wallet threat
Quantum computing is the long-feared threat to public-key cryptography, but the warning reframes the closer risk as conventional mathematics accelerated by AI. An open AI research lab recently released hundreds of new mathematical findings across algebra, theoretical computer science, and mathematical logic, a pace that researchers say shows how fast machine-aided proof and discovery are advancing. The same lab used a team of 10,000 autonomous AI agents working in parallel to solve the Navier-Stokes equation, one of the most famous and difficult unsolved problems in mathematics and physics, in just 88 hours.
That combination of speed and scale is what makes elliptic curves a worry. As the researcher who raised the alarm put it, recent days have been humbling for human mathematical intuition, with long-held, unquestioned hypotheses falling. Elliptic curves could be especially vulnerable to a future superintelligence because the curves carry rich structure, with room for advanced techniques such as Schoof, Frobenius, and pairings. By contrast, hash functions are designed to minimize algebraic structure and are harder to attack with the same tools.
What “bunker mode” means for crypto wallet security
Bunker mode in this context is a user-side habit, not a protocol change. The practical step is to keep funds in addresses whose public key has not yet been revealed on-chain. A public key is only exposed after the address sends its first transaction, so any address that has only ever received crypto and never spent from it still has its public key hidden.
The migration playbook looks like this:
- Large and sophisticated holders should be the first to move funds to fresh addresses.
- After every transaction signed from an address, any remaining balance should be moved to a new address.
- The migration should be gradual, controlled, and orderly, not a panic move.
- Users should not scramble to move funds today, but should take the cryptography risks from AI-accelerated math seriously.
Both researchers stressed that any move itself carries risk. One noted that they have personally lost more money in botched migrations than in all hacks combined, and the other warned that a rushed migration would do more harm than good.

The roadmap shift toward hash-based cryptography
The concern extends beyond elliptic curves. Lattice-based cryptography, which underpins many proposed post-quantum standards, could also be weakened by AI-driven mathematical advances. So far most people have been in the mode of thinking “elliptic curves broken, hashes safe, lattices safe,” but there is a good chance the concrete security of lattices will take serious hits from the next two years of AI math.
That is one major reason the Ethereum lean roadmap has been going in a “hash-only” direction, reducing reliance on signature schemes that an AI-accelerated math breakthrough could compromise. Hash functions, with their minimal algebraic structure, are treated as the more durable layer for now.
How holders can reduce exposure today
The risk is not quantum, but conventional mathematics overturning unproven cryptographic hardness assumptions. For everyday users, the recommended posture is straightforward: if it is not difficult, keeping funds in addresses which have not yet been used to make a transaction is a good idea. New receiving addresses can be generated from any wallet, and funds can be swept between them in small batches.
Institutions and large holders are expected to lead the controlled mass migration, since they hold the most value per address and have the operational capacity to test migrations safely. Smaller holders can follow the same pattern at their own pace. Anyone planning a move should rehearse it with small amounts first, verify that the new addresses are correctly backed up, and avoid moving everything in a single transaction that would expose a new public key all at once.
FAQ
What is crypto “bunker mode”?
Bunker mode is the practice of keeping cryptocurrency funds in wallet addresses whose public key has not been exposed on-chain, typically by using fresh addresses that have never sent a transaction. It reduces the attack surface if AI-driven math advances eventually allow ECDSA private keys to be derived from public keys.
How could AI break crypto wallet security?
AI systems are rapidly advancing in pure mathematics, including algebra, number theory, and logic, which are the foundations of elliptic curve cryptography. If AI helps discover new attacks on the discrete logarithm problem behind ECDSA, private keys could be reconstructed from exposed public keys, emptying affected wallets.
Should crypto users move funds to new addresses now?
Researchers advise a gradual, controlled migration rather than a panic move, starting with large and sophisticated holders. The key rule is to keep funds in addresses that have never broadcast a public key, and to move any remaining balance to a fresh address after each transaction.
