What problem does it solve?

SIWA enables AI agents to authenticate with services using their ERC-8004 onchain identity.

Core Features & Use Cases

  • Server-side verification and nonce-based replay protection.
  • ERC-8128-based authenticated request middleware across Next.js, Express, Hono, and Fastify.
  • Modular SDK with signer, verifier, nonce-store and middlewares for multiple runtimes.

Quick Start

Install and integrate the SIWA SDK to begin signing and verifying agent identities in your app.
