Identity Bridge - Privacy-Preserving Credential Verification

How It Works

The Problem

Personal data on-chain is reckless. Identity is fragmented across ecosystems.

Our Solution

Identity Bridge stores only credential hashes on blockchain. Never your personal info. Issue on Ethereum, verify on Solana. User-sovereign control.

Privacy-first architecture
Cross-chain verification in one call
Zero PII exposure
User controls their data

Abstract lock representing privacy preserving credentials

Private Credentials

Issue once, verify everywhere

Supported Chains

Deployed to the following testnets. More coming.

Arbitrum

Base

Ethereum

Polygon

Optimism

Rootstock

Solana

Starknet

Real-World Use Cases

Identity Bridge can power privacy and trust challenges across industries.

Employment & Hiring

Candidates prove skills and experience without exposing salary history or personal details. Employers verify legitimacy without storing PII.

Prove "5+ years Solidity experience" without revealing compensation
Verify education credentials cross-chain
Privacy-first talent matching

Professionals collaborating during a hiring cycle

Zero-Knowledge Hiring

Trust talent without PII

Personal Reputation & Agency

Portable credentials prove trust scores and account quality without exposing transaction history or raw vault data.

Prove "account 6+ months old, 95%+ completion rate"
Carry reputation across platforms
Never expose underlying transaction data

Portable Reputation

Signal trust everywhere

Vehicle & Fleet Verification

Insurance, lending, and marketplaces verify vehicle health and driver behavior via ZK proofs, with zero raw telemetry exposure.

Prove "mileage < 100k AND safe-driving-score > 80"
Enable DeFi lending against fleet assets
Cross-chain vehicle credentials

Autonomous vehicles and fleet telemetry concept

Telemetry Proofs

Fleet data without exposure

AI Agent Reputation

Autonomous AI agents prove reliability and guardrail compliance without exposing transcripts, vault data, or internal ledgers to external systems.

Prove "agent completed 500+ support tasks with 96% success and zero policy flags"
Carry portable trust credentials across dApps and protocols
Never expose raw transcripts, notes, or transaction history
