System Documentation

What problem does it solve?

This Skill helps developers build non-custodial Ethereum wallets without seed phrases by deriving wallet keys from passkeys while reducing exposure from XSS and application-layer compromise.

Core Features & Use Cases

  • Passkey Wallet Derivation: Implements WebAuthn PRF-based key derivation with HKDF and secp256k1 wallet creation for EVM applications.
  • Secure Key Isolation: Provides an iframe-based wallet architecture with RPC communication so private keys remain isolated from the parent application context.
  • Compatibility and Recovery Patterns: Covers PRF platform detection, LongBlob fallbacks, encrypted recovery flows, and server-side WebAuthn verification for production wallet experiences.

Quick Start

Ask the skill to add a passkey-derived Ethereum wallet to a web application with iframe isolation and WebAuthn authentication.
