EIP-712 Signing

EIP-712 is a standard for typed structured data hashing and signing, designed to make off-chain signatures more readable and secure for users. Before EIP-712, users were often asked to sign raw, incomprehensible byte strings, which made it impossible to verify what they were consenting to.

EIP-712 allows protocols to present the data in a structured, human-readable format, such as a trade order or a governance vote, directly in the wallet interface. This significantly improves the user's ability to understand the intent and consequences of their signature.

It is a critical security standard for decentralized applications that rely on off-chain order books or meta-transactions. By enforcing a consistent structure, it prevents signature replay attacks and improves the overall integrity of user consent.

The adoption of EIP-712 has become a standard requirement for reputable decentralized protocols. It is a fundamental piece of the infrastructure that protects users in the complex world of off-chain message signing.
