Claude Helps Reconstruct P-256 Public Seed for Ethereum Passkey Signing
Anthropic reported that Claude helped reconstruct the public seed behind P-256, a cryptographic curve used for Ethereum passkey signing. The seed is not a wallet key and no new weakness was reported. The Ethereum connection is through EIP-7951, which specifies verification of signatures using P-256. This connects wallet authorization with signing capabilities built into devices and authenticators.
