Field covering protection of cryptographic keys, signatures, and infrastructure—wallets, custodians, exchanges—from theft, bugs, and quantum-era attacks.
Researchers found an integer overflow in the XRPL payment engine that could theoretically have created XRP from nothing. The 18 trillion XRP figure came from controlled testing, and a dev.to write-up says nobody minted it on the public ledger.

Justin Sun says Tron is ready to bring quantum resistance to mainnet at any time, now that post-quantum signatures run on its Nile testnet. Mainnet still needs separate governance approval, Crypto Briefing reported, and the opt-in design reaches only holders who adopt it.

GHSA-7g4w-cg88-2cq2 was reported on April 25, judged no threat to live funds, and quietly patched on August 19. Attackers drained six chains starting the next day, and the only real fix breaks state.

Eigen Labs' ECDSA.Fail leaderboard took the resource score for one step of a quantum key recovery from 10.75 billion to 1.496 billion by July 26, while the defense side works to fixed dates in 2029 and 2030.

Three regulators have now dated the migration away from today's encryption, and the nearest date belongs to FINMA, which wants supervised institutions to get a post-quantum strategy through the board by mid-2027.
Reality
The 26-day figure is a runtime rather than a date, and it works out to one logical Toffoli every 57.6 milliseconds on trapped-ion hardware whose scale IonQ's roadmap does not reach until 2028. No error rates are published to check it.
Reality
Google has floated 2029 for moving digital assets off elliptic curve cryptography. Roughly 93% of the market sits on it, and no single party can order the migration.
