Age & Sale-Eligibility Verification
Prove only "old/eligible enough to sell to" — without the birth date or ID — at POS or online.
Delegate API billing to AI agents.
Without handing over the API key, verify a billing-ceiling / allowed-API / validity delegation via x402 at runtime — and let the AI call only inside that scope.
Delegate expense approval to AI agents.
Issue expense-approval authority as a delegation with a spend ceiling, categories and validity — and let the AI approve autonomously only inside that scope.
Delegate procurement to AI agents.
Issue ordering authority as a delegation scoped by spend ceiling, category and approved vendors — and let the AI order autonomously only inside that scope.
Prove agent-to-agent transactions with delegation chains.
Record agent-to-agent delegations as a chain, making it verifiable whether the final transaction rests on a legitimate chain of authority.
Agentic Payment Fraud
Bind every agent payment to a verifiable delegation, spend limit, and jurisdiction attribute — before settlement.
Prove EU AI Act compliance without sharing originals.
Show a high-risk AI's AI Act compliance as per-provision attribute proofs, without surfacing training data or model details.
AI Audit Log Proof
Fix an AI decision's basis at decision time; explain it later, even after model updates.
Let AI Use Internal Documents Without Touching the Raw Data
Let AI use only the needed facts, with proof — never the raw data.
Benefit & Subsidy Eligibility Proof
Prove only "meets the eligibility criteria" — the granting body verifies without holding the data.
CBAM Supplier Attestation
Prove CBAM-required supplier attributes by ZK attestation, keeping the underlying production data inside each supplier's perimeter.
Counterparty Screening — Pass the Result, Not the Reasons
Pass only the credit/sanctions decision — reasons and scores stay private.
Presenting Academic & Employment Credentials
Prove you hold a credential without sending the original; employers and schools verify it.
Need-to-Know Customer Flags
Pass only the needed handling flag to the front line; the reason stays with authorized staff, tamper-proof.
DeFi Bridge Verification
Independently verify a cross-chain message's origin before receipt.
Delegated Treasury
Issue an AI agent's spending authority as an on-chain spend-control attestation.
EUDR Traceability
Prove EUDR-required attributes across multi-tier supply chains without sharing supplier raw records.
Financial Data Exfiltration Defense
Make cross-org data access tamper-proof and verify who accessed what.
Tamper-Proof Incident & Complaint Records
Prove "when and how" an incident was handled — without exposing customer data or details.
Tamper-Proof Internal Control & Approval Records
Prove approvals and segregation of duties were legitimate — auditors verify without seeing the contents.
KYC/AML Selective Disclosure
Meet regulatory requirements by proving only the needed KYC attributes, not sharing them.
Long-Term Contract Records, Provable Years Later
Prove contract and quote records tamper-free, without revealing contents — even years later.
LP Claim Attestation
Verify LP eligibility attributes per regulatory regime without exposing individual KYC or balance data.
Prove AI model integrity across version changes, retroactively.
Pin the decision-time modelId@timestamp and policyHash so past AI decisions stay retroactively verifiable after a model update.
Multi-Agent Workflows
Bind multi-hop delegation as per-node proofs, traceable back to the originating principal.
Detect prompt injection without exposing content.
Commit the normalized form of the input and verify "human-saw = AI-read" integrity — without exposing the content.
Public Procurement Attestation
Confirm bidder eligibility per the tender's specific requirements without forcing raw-document disclosure.
Proof of Qualified Assignment & Safety Training
Prove and verify "qualified" without exposing the worker's record.
RAG Content Provenance
Fix document provenance at RAG ingestion so AI citations stay traceable.
RAG Source Attestation
Bind each citation to its source version to preserve citation integrity.
Store-Network License, Hygiene & Insurance Compliance
Verify each store validly holds the required licenses, hygiene, and insurance — without originals.
Verify Supplier Licenses, ISO & Certificates Without Handing Over Originals
Confirm a license or ISO is valid without receiving the original certificate.
Supply Chain Component Provenance
Chain component provenance with issuer signatures so assemblers can verify it.
Supply Chain ESG Compliance
Prove CBAM/EUDR conformance via a chain of supplier attributes while protecting trade secrets.
Work-Fitness Attestation
Prove staff meet required health checks, training, and qualifications — without exposing health data.
X402 Commerce
