SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill enables users to authenticate into web applications using their Ethereum wallet, replacing traditional username/password or OAuth methods with a more secure and decentralized approach.

Core Features & Use Cases

  • Wallet-Based Authentication: Implement Sign-In with Ethereum (SIWE) for secure user login.
  • Session Management: Manage user sessions using encrypted cookies via iron-session.
  • Use Case: Allow users to log into your dApp by signing a message with their MetaMask wallet, creating a secure, non-custodial session.

Quick Start

Use the siwe skill to add Sign-In with Ethereum authentication to the 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?▼

Sign-In with Ethereum authentication is integrated by handling nonce generation, message signing, and signature verification using viem utilities, while iron-session manages the resulting cookie-based user sessions.

What is the best way to manage Web3 user sessions after wallet login?▼

Web3 user sessions are managed securely using iron-session, which encrypts browser cookies to maintain a non-custodial session after a user successfully signs a SIWE message with their Ethereum wallet.

How does nonce generation and signature verification work for Ethereum login?▼

Nonce generation creates a unique string for each login attempt, and signature verification uses viem utilities to cryptographically validate the signed message against the user's Ethereum address before establishing a session.

Can I use iron-session for secure cookie-based session management in a Scaffold-ETH 2 project?▼

Yes, iron-session is used within the Scaffold-ETH 2 environment to provide encrypted, cookie-based session management specifically designed to secure Web3 authentication flows after wallet login.

Does Sign-In with Ethereum replace traditional OAuth methods for Web3 authentication?▼

Sign-In with Ethereum replaces traditional username, password, and OAuth methods by allowing users to authenticate into web applications through a decentralized, secure wallet signature instead of third-party providers.

What are the prerequisites for adding SIWE authentication to a Web3 project?▼

Adding SIWE authentication requires a Scaffold-ETH 2 project setup, the iron-session dependency for cookie management, and viem utilities to handle the underlying Ethereum message signing and verification logic.
