SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires iron-session, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill enables secure, wallet-based authentication for web applications, replacing traditional username/password or OAuth flows with a decentralized, user-controlled method.

Core Features & Use Cases

  • Sign-In with Ethereum (SIWE): Implement EIP-4361 compliant authentication using wallet signatures.
  • Session Management: Securely manage user sessions via encrypted cookies using iron-session.
  • Use Case: Integrate a decentralized login system into your dApp, allowing users to authenticate simply by signing a message with their existing Ethereum wallet, enhancing security and user experience.

Quick Start

Use the siwe skill to add Sign-In with Ethereum authentication to your Scaffold-ETH 2 project.

Frequently Asked Questions about siwe

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement Sign-In with Ethereum authentication in my dApp?▼

Session management for Web3 authentication is handled using `iron-session` to create and manage encrypted cookie-based sessions. This ensures secure persistence of user login state across requests after the Ethereum wallet signature is verified.

Does this SIWE authentication method work with Scaffold-ETH 2?▼

Yes, this SIWE authentication method is specifically designed to work with Scaffold-ETH 2 projects. It leverages viem and iron-session to integrate secure wallet-based login flows directly into the framework's architecture.

What is the process for verifying an Ethereum wallet signature during login?▼

Verifying an Ethereum wallet signature during login involves generating a unique nonce, having the user sign an EIP-4361 formatted message, and validating that signature. This Skill facilitates message verification and subsequent secure session creation.

How do I destroy a user session after Web3 authentication?▼

Destroying a user session after Web3 authentication is supported through the session management features provided by `iron-session`. You can securely check and destroy encrypted cookie sessions to log users out of the decentralized application.
