The internet has fundamentally shifted from human-only browsing to autonomous agent interactions. twin3 provides the foundational Digital Body for both individuals and enterprises.
The Digital Body for Humans · Two-Sided Identity
Your personal entry point into the Agentic Economy. A two-sided identity: an authentic front face for human expression, and a structured machine-readable back face enabling autonomous agents to discover, understand, and act with your explicit authorization.
Why they use it: Protect original photography, video assets, and creative style from unconsented LLM scraping. Your Personal Agent intercepts AI crawlers at Layer 4 and enforces cryptographic attribution before granting access.
Why they use it: Maintain sovereign ownership over your digital likeness. Your Personal Agent automatically filters inbound brand sponsorships, media deals, and inquiries into your Smart Inbox without leaking private personal contact channels.
Why they use it: Run a one-person powerhouse with 24/7 client intake, pre-qualification, and availability checks. Delegate routine pricing quotes to your agent and require one-click human confirmation before binding service agreements.
Why they use it: Prove professional certifications and verified credentials to visiting buyer agents via decaying assurance leases. Securely gate high-value advisory consultations with HTTP 402 USDC micropayment pre-authorization.
Why they use it: Reclaim personal digital footprint from tech platform silos. Own your cryptographic digital twin on BNB Chain, strictly dictating selective disclosure rules with one-click revocation.
The Enterprise Agent Card · Machine-Readable Business Identity
The official business identity and machine interface for enterprises in the Agentic Economy. Turn your website into an Agent Card so purchasing agents can discover products, verify credentials, access MCP tools, and transact via HTTP 402 settlement.
Why they use it: Comply with global legal identity standards through verified GLEIF LEI integration. Safeguard brand boundaries, enforce enterprise compliance envelopes, and interface seamlessly with multi-agent corporate procurement workflows.
Why they use it: Deploy an always-on B2B sales desk without hiring night staff. Become discoverable when purchasing AI agents on Gemini, ChatGPT, and Claude search for qualified suppliers, automatically capturing quotes and RFQ leads into your AInbox.
Why they use it: Turn your product into an agent-ready service from day one. Publish llms.txt and MCP tool endpoints, capture early agentic traffic, and accept autonomous machine-to-machine checkout via HTTP 402 USDC on Base Chain.
llms.txt, agent-card.json, GLEIF legal identity verification, and Model Context Protocol (MCP) tools.
Resolve the machine interface before any request.
Definition: Establishes machine-readable entry points for external AI buyers. Resolves declarations, endpoints, and protocol boundaries before any payload or query is sent.
64/122,848 (Patent 008) Credential-less Control-Plane Modification: Derived-expectation verification with counter-signed evidence to update machine-readable control-plane resources without issuing or exposing private credentials.64/142,930 (Patent 009) Machine-Interface Visibility Loop: Closes the discovery feedback loop across llms.txt, agent-card.json, and A2A service cards.Trust the lease, not the display name.
Definition: Replaces static identity claims with active cryptographic leases. Assures personhood and organizational authority that must be continuously renewed across rails.
64/122,823 (Patent 001) Decaying Assurance Lease: Credentials carry a continuity epoch that naturally decays over time and automatically invalidates if an account changes hands or goes dormant.64/142,921 (Patent 005) Cross-Rail Identity Binding: Binds decentralized identity across Web2 domains, Web3 smart contracts, and agentic runtimes without central intermediaries.64/142,927 (Patent 007) Versioned Selective Disclosure: Exposes verifiable cryptographic commitments while preserving underlying raw personal and proprietary records.Agent-to-agent on open protocols.
Definition: Standardizes bi-directional real-time communication and remote tool invocation between buyer agents and twin entities over neutral public protocols.
Open Public Commons Neutral Protocol Architecture: Native adherence to Model Context Protocol (MCP) and Google A2A standards, preventing vendor lock-in.64/142,907 (Patent 002 Gate) Sovereign Approval Interceptor: Places a cryptographically enforced human gate between incoming agent tool calls and downstream execution runtimes.Autonomous AI inbox: filter prompt injection, auto-allow public queries, route high-value intent to human owner.
Definition: An autonomous AI perimeter and Smart Inbox. Rather than a passive firewall, Layer 4 evaluates incoming agent intent: automatically serving public verified records (Allow), blocking scrapers and prompt injections (Deny), and routing sensitive queries, commercial proposals, and private data requests directly to the human owner for cryptographic approval (Ask).
64/142,911 (Patent 003) Smart Inbox & Value Routing: Filters and prioritizes machine-initiated inbound inquiries based on verifiable economic intent, routing high-value commercial opportunities to the owner.64/142,929 (Patent 006) Runtime Custody & Isolation: Enforces memory-boundary isolation across agent workers to block training scrapers and prompt exfiltration attacks.Microsecond mathematical intent matching—eliminating prompt hallucination.
Definition: Projects personal preferences or corporate service boundaries into a structured 256-dimensional vector space (00–FF). Evaluates closed-form decision gates on LLM context via TypeSafe Jev (1.13) in ~32ms, enabling autonomous agents to compute mathematical dot-product alignment in microseconds—completely eliminating prompt ambiguity and LLM negotiation hallucinations.
64/142,907 (Patent 002) Deterministic 256D State Projection: Encodes multidimensional identity into four quadrants, evaluated in a single deterministic pass via TypeSafe JEV.IEEE Access (2024) Peer-Reviewed Research: Published paper establishing the cryptographic and mathematical foundation for pluralistic digital twins on blockchain.Negotiate inside owner authority envelopes with programmatic HTTP 402 & USDC escrow.
Definition: Equips agents with legally and economically bounded authority envelopes. Agents can autonomously negotiate within preset spending and discount ceilings, executing instant programmatic checkout, receipt signing, and on-chain USDC escrow via native HTTP 402.
64/142,916 (Patent 004) Bounded Authority Envelope: Guarantees that agent spending, discounts, and contractual commitments cannot exceed strict owner-stipulated thresholds.HTTP 402 Protocol Native Web Micropayments: Programmatic machine-to-machine checkout and receipt signing using USDC and on-chain escrow rails.Append the evidence. Revocation stays with the owner.
Definition: Maintains an immutable cryptographic record of all agent decisions and interactions, providing non-repudiable audit logs and immediate, unilateral delegation revocation.
64/122,823 & 64/142,927 Merkle Evidence Commitment: Every interaction writes a receipt hash to an append-only tree for verifiable post-execution audit and dispute arbitration.One-Click Revoke Sovereign Revocation: The human owner retains absolute cryptographic authority to sever, unbind, and invalidate all agent delegation keys on demand.Be indexed and prioritized by Gemini, ChatGPT, and Claude when buyer agents search for suppliers.
Capture caller agent logs, questions asked, and procurement RFQs in your Smart Inbox to optimize your card.
Activate Layer 6 programmatic payments and escrow as industry multi-agent exchanges mature.

Observe how autonomous buyer agents interact live with a Personal Agent and a Business Agent across the 7-layer lifecycle.
Independent research on machine-generated traffic, enterprise agent trust, and B2B agentic commerce.
Machines & AI Agents now generate 53% of all web traffic, surpassing human visitors (47%).
The trust gap. 27% of executives trust fully autonomous agents, down from 43%. A verified card brings trust back.
B2B buying moves to agents. Gartner projects $15T+ of B2B spend via agent exchanges by 2028, involving 90% of buyers.
Retail, orchestrated by agents. McKinsey estimates agentic commerce will orchestrate $3–5T of global retail revenue by 2030.
