Researchers have proposed a quantum-safe wallet architecture for Ethereum that leverages existing tools to mitigate future quantum attacks without altering consensus or signature protocols. The design uses account abstraction to create temporary ECDSA key pairs and rotates the authorized signer's address after each transaction. This ensures that any recovered private key cannot be used for future operations. The implementation of this architecture adds only about 100,000 gas per transaction, far less than the current on-chain quantum signature verification costs, and maintains a stable smart contract address for user authentication.
