The Quiet Restructuring: Why ERC-4337 Matters Beyond Wallets

ERC-4337 is widely misunderstood as merely a wallet upgrade, but it represents a fundamental architectural shift that decouples transaction validation from execution, transforming static transactions into programmable pipelines. This restructuring introduces critical new constraints around deterministic validation and economic risk management through gas, forcing developers to fundamentally rethink system design. The shift from protocol-level transaction validation to contract-based execution engines changes not just how transactions work, but how trust and security are architected on Ethereum.
