SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires siwe, fastapi, pydantic, jwt, web3, ens, aiohttp, spoon_ai, and includes scripts (resource) components.

What problem does it solve?

Decentralized identity and authentication for Web3 apps by providing SIWE-based login, ENS resolution, secure session management, and verifiable credentials infrastructure.

Core Features & Use Cases

  • SIWE-based sign-in flow: authenticate users via Ethereum wallets and establish a session.
  • ENS resolution and reverse lookup: map human-readable names to addresses and vice versa.
  • Web3 session lifecycle: create, validate, refresh, and destroy sessions with optional Redis support.
  • Verifiable credentials integration: support identity proofs and access controls.

Quick Start

Run the SIWE flow to sign in with Ethereum and obtain a session token.

Frequently Asked Questions about web3-identity-auth

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

FAQPage Schema
How do I implement wallet-based login for a Web3 application using SIWE?▼

Wallet-based login uses SIWE message creation, nonce handling, and signature verification to authenticate Ethereum wallet users and establish a secure session token for Web3 applications.

What is the process for ENS resolution and reverse lookup in decentralized identity?▼

ENS resolution maps human-readable names to Ethereum addresses and vice versa via reverse lookup, enabling verifiable identity proofs across dApps and web services using the web3 and ens libraries.

How do I manage the Web3 session lifecycle including token validation and refresh?▼

Web3 session lifecycle management allows you to create, validate, refresh, and destroy user sessions using JWT, with optional Redis support for distributed storage and secure environment configuration.

Does FastAPI support integrating decentralized identity authentication for dApps?▼

Yes, FastAPI supports decentralized identity authentication by integrating SIWE and pydantic for data validation, enabling secure wallet-based login and session management directly within your web service endpoints.

Can I use verifiable credentials for access control across multiple web services?▼

Yes, verifiable credentials integration supports identity proofs and access controls, allowing authenticated wallet users to maintain verified authorization across dApps, web services, and agents.

What are the limitations when using SIWE for authentication without secure storage?▼

Without secure storage or Redis, SIWE authentication is limited to local session management, reducing scalability across distributed web services and affecting session persistence during server restarts.
