When Type Hashes Lie: EIP-712 Implementation Errors in DeFi - Evidence from Comprehensive Solidity Code Review

Large-scale automated validation of 288 EIP-712 implementations reveals 91.7% contain TYPEHASH errors. Identifies three production patterns and the self-consistency trap. Now includes comprehensive Chinese translation and expanded n=288 sample analysis.

Abstract

Large-scale automated validation of 288 EIP-712 implementations reveals 91.7% contain TYPEHASH errors. Identifies three production patterns and the self-consistency trap. Now includes comprehensive Chinese translation and expanded n=288 sample analysis.
