ONE id

Decentralized Biometric Identity for the ONE Ecosystem

ONE id is a biometric identity service that allows users to verify their identity once through client-side facial recognition and associate it with one or more wallet addresses. The resulting credential is reusable across all applications in the ONE ecosystem.

Platform: id.expl.one

Overview

ONE id addresses a common problem in decentralized applications: proving that a user is a unique human without relying on centralized identity providers. It combines browser-based biometric enrollment with on-chain wallet signature verification to produce a single reusable identity credential.

One verification. Every application. No centralized authority.

Core Features

Biometric Enrollment

  • Client-side facial recognition powered by face-api.js (TensorFlow.js-based)
  • Generates a 128-dimensional mathematical descriptor entirely in the browser
  • No raw image or video data is transmitted or stored
  • Three-point consecutive detection for reliable verification

Wallet Association

  • Connect one or more EVM-compatible wallets via RainbowKit
  • Supported chains: Ethereum, Polygon, Arbitrum, Optimism, Base
  • Cryptographic signature binds wallet addresses to the biometric descriptor
  • Multi-wallet support under a single identity

Unified Access

  • A single verified identity propagates across all ONE ecosystem applications
  • Authenticate once, operate everywhere
  • Sybil-resistant identity protocol prevents duplicate accounts

How It Works

  1. Scan: The client captures a facial scan using your device camera. A mathematical descriptor is generated entirely in the browser — no raw biometric data leaves your device.
  2. Sign: Connect one or more EVM-compatible wallets and sign a verification message. The signature cryptographically binds your wallets to your biometric descriptor.
  3. Access: Your verified identity propagates across the ONE ecosystem. One credential grants access to every application.

Privacy Model

ONE id implements a privacy-first architecture:

  • Client-side processing — All facial recognition runs locally in the browser
  • Encrypted descriptors — Only an encrypted mathematical representation is stored server-side
  • Zero raw data retention — No face images, video frames, or raw biometric data are retained or transmitted
  • Non-reversible — The stored descriptor cannot be reversed to reconstruct a facial image
  • Sovereign identity — Users control their own biometric data

Technology Stack

ONE id is built with modern web technologies for optimal performance:

  • Frontend: React 19, TypeScript
  • Build Tool: Bun, Vite
  • Styling: Tailwind CSS
  • UI Components: Shadcn UI
  • Wallet Integration: wagmi + viem + RainbowKit
  • Biometrics: face-api.js (TensorFlow.js-based)
  • Animations: Framer Motion

Use Cases

ONE id enables a range of identity-dependent features across the ecosystem:

  • Sybil resistance — Prevent duplicate accounts and bot activity across ONE applications
  • Cross-application identity — A single verification grants access to ONE pump, ONE world, ONE network, and all future projects
  • Trustless verification — Prove uniqueness without revealing personal information
  • Multi-wallet management — Associate multiple wallet addresses under one verified identity

Roadmap Status

Current Status: Pre-release

The landing page is deployed at id.expl.one with verification currently disabled. Backend integration, biometric enrollment, and wallet association are implemented but not yet publicly accessible.
