SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill simplifies the integration of EIP-712 typed data signing and verification into Scaffold-ETH 2 projects, enhancing security by allowing users to understand and approve exactly what they are signing.

Core Features & Use Cases

  • EIP-712 Integration: Seamlessly add typed data signing using wagmi hooks and viem utilities.
  • Frontend & Backend Verification: Supports both client-side and server-side signature verification.
  • Use Case: Implement a feature where users can sign off-chain messages (like proposals or acknowledgments) with clear, human-readable details presented by their wallet, preventing phishing and errors.

Quick Start

Integrate EIP-712 typed data signing and verification into your Scaffold-ETH 2 project.

FAQPage Schema
How do I implement EIP-712 typed data signing in a Scaffold-ETH 2 project?▼

To implement EIP-712 typed data signing in Scaffold-ETH 2, use wagmi hooks and viem utilities to define domain separators, type definitions, and generate messages for client-side and backend verification workflows.

What is the best way to verify off-chain signatures on both frontend and backend?▼

Verifying off-chain signatures on frontend and backend requires using viem utilities to validate the EIP-712 typed data structure, ensuring secure message integrity across client-side and server-side processes.

Can I use wagmi and viem together for Ethereum dapp development?▼

Yes, you can use wagmi and viem together for Ethereum dapp development to facilitate secure EIP-712 typed structured data signing and verification workflows within your project.

Why do I need domain separators and type definitions for EIP-712?▼

Domain separators and type definitions are required for EIP-712 to securely structure typed data, allowing users to clearly understand and approve exactly what they are signing to prevent phishing and errors.

Does Scaffold-ETH 2 support human-readable wallet signing for dapp proposals?▼

Scaffold-ETH 2 supports human-readable wallet signing for dapp proposals by integrating EIP-712 typed data signing, presenting clear details to users for secure off-chain message approvals.

What are the limitations of using EIP-712 for off-chain signing?▼

A limitation of using EIP-712 for off-chain signing is that it requires explicit implementation of domain separators and type definitions using wagmi and viem to ensure proper on-chain verification.
