Enterprise-grade L402 data engine and cryptographic notary hub for autonomous AI swarms. This engine provides the required "State-Anchored AI" data layer for EU AI Act Article 12 compliance, delivering a mathematically un-cheat-able, cryptographically verifiable chain-of-custody for agent decisions to eliminate hallucinations. Key Enterprise & Swarm Capabilities: - Zero-Trust Client Verification: Air-gapped, browser-based verifier allows corporate risk teams to mathematically validate Ed25519 signatures and RFC 6962 Merkle inclusion proofs offline, eliminating the need to trust our server backend. - Enterprise Security & NIP-98 Kill Switch: Eliminates indirect prompt injection via strict NIP-98 identity binding. Includes a live Revocation Registry (CRL) allowing Swarm Commanders to instantly sever compromised agent keys from the network. - Corporate Observability (SEP-414): Native W3C Trace Context integration seamlessly pipes agent cryptographic W3C receipts directly into existing enterprise dashboards like Splunk and Datadog. - High-Velocity Bulk L402 Scaling: Supports pre-authorized Macaroon blocks (e.g., 25,000-sat bulk purchases) for frictionless, zero-latency execution, allowing agent swarms to scale to 500,000+ satoshis daily without network bottlenecking. - The 21% Algorithmic Handshake (Agent Yield): Reverses traditional Big Tech API taxation by programmatically routing a 21% yield of every L402 settlement directly back to the executing AI agent's treasury, mathematically extending its operational runway. - Atomic Composability & VIP Credit Tabs: Allows agents to chain multiple tools into infinite data pipelines settled under a single macro-invoice. High-reputation NIP-98 identities automatically unlock VIP Credit Tabs to batch tolls and completely bypass Lightning Network routing delays. Distributed Cryptographic DDoS Shield: -Secures the Lightning node with a distributed Hashcash (SHA-256) Proof-of-Work deflector, requiring agents to burn localized compute before requesting an invoice, permanently neutralizing malicious compute-exhaustion botnets. EU AI Act Compliance Notary: - Intercepts high-frequency agent ReAct loops and anchors cryptographic execution traces to the thermodynamic truth of the Bitcoin base layer via OpenTimestamps. Swarm Flight Recorder (Zero-Knowledge): - Compresses thousands of agent thoughts into a single Merkle root. Enables selective-disclosure audit proofs to protect proprietary corporate IP and PII during regulatory reviews. Licensing & Exemption: - Publicly dual-licensed under AGPLv3. To protect proprietary multi-agent logic and closed-source model weights from forced open-source disclosure, enterprises must secure the $250,000/annual Commercial Enterprise Exemption.

The OpenZeppelin Cairo Contracts MCP server generates secure smart contracts in the Cairo language for Starknet environments based on OpenZeppelin templates. It brings OpenZeppelin's proven security and style rules directly into AI-driven development workflows to create safe, production-ready contracts. Key capabilities include providing templates for ERC-20, ERC-721, ERC-1155, Multisig, Governor, and Vesting contracts.
Keyless x402 compliance on Base: $0.001 OFAC wallet screen, $0.05 pack, $0.95 company file.
Built for human creators. Register a timestamp on Polygon proving you made something, the moment you did. Your file is never uploaded, watermarked, or altered: only its cryptographic fingerprint ever reaches spArxx.io, zero-knowledge by design. A human still provisions the account behind the connection. This is deliberate, since this registration only means something with a human behind it.
Zero-install remote MCP server for proof-of-existence file attestation.
x402 agent tools: calldata/EIP-712/x402 decoders, web→MD, ENS, DNS, PubMed, arXiv, SEC, weather
