Trustless by Design: How Modular Validation Enhances Smart Wallet Security

In the evolving landscape of decentralized finance (DeFi) and self-custody, wallet infrastructure is undergoing a radical transformation. Special attention should be given to Account Abstraction. It addresses the limitations of user experience and the complexities of traditional Externally Owned Accounts (EOA) wallets, offering greater flexibility and smarter wallet management.Different networks implement Account Abstraction in different ways. Starknet, for example, has it natively integrated at the protocol level. Ethereum, by contrast, does not yet provide native support, but relies on a clever workaround, the ERC-4337 standard, which delivers Account Abstraction functionality without requiring changes to the Ethereum protocol. Account Abstraction (ERC-4337) transforms wallets into programmable smart contracts, unlocking advanced functionality such as spending limits, multi-signature verification, session keys, and customizable recovery…
