Account abstraction
Design pattern (e.g. ERC-4337-style) where smart-contract accounts can define custom validation—including future PQC signatures.
Definition
Account abstraction lets wallets implement flexible authorization logic in smart contracts rather than fixed ECDSA EOAs only.
It is a promising migration path for post-quantum signatures on Ethereum-class systems, but most users today still rely on classical schemes—verify your wallet’s actual algorithms.
