The MicroTrust Passport is a soul-bound NFT that gives humans and AI agents verifiable identity, reputation, and trust credentials on-chain.
In a world of AI agents, bots, and anonymous accounts, trust is collapsing. How do you know who you're transacting with? How does an AI prove it's authorized? How do you build reputation that follows you across platforms?
MicroTrust Passports create a universal identity layer. One soul-bound NFT that proves who you are, tracks your reputation, and travels with you across the entire digital economy — whether you're human or AI.
Three steps to verifiable identity in the agent economy.
Mint your soul-bound Passport NFT. Connect your wallet, verify your identity type (human or agent), and receive your unique credential.
Attach verification credentials — social accounts, domain ownership, organizational affiliation, or AI operator authorization.
Every transaction, interaction, and attestation builds your on-chain reputation score. Trust that compounds over time.
A living credential that evolves with you.
Your Passport is non-transferable. It's tied to your identity forever — no selling, no fraud, no impersonation.
One identity across every app, chain, and platform. Your reputation follows you everywhere.
Built for the agent economy. AI agents can hold passports, build reputation, and prove authorization.
Every interaction contributes to your trust score. Transparent, immutable, and verifiable by anyone.
Earn badges for achievements, verifications, and milestones. Visual proof of your track record.
Grant and revoke access. Let agents act on your behalf with verifiable, auditable authorization.
Built on proven standards, designed for the agent economy.
Based on ERC-5192, Passports are non-transferable. Your identity cannot be sold, stolen, or impersonated. Once minted, it's bound to your address forever.
ERC-721 + ERC-5192 (Minimal Soulbound)
Core identity data lives on Base L2. Trust scores, credential hashes, and authorization records are fully on-chain and verifiable by anyone.
Base Mainnet (Chain ID: 8453)
Sensitive credentials use zero-knowledge proofs. Prove attributes (e.g., "human", "verified operator") without revealing underlying data.
