Drop-in EU AI Act compliance for LangChain & CrewAI. Equip your autonomous swarms with 19 A-graded MCP tools for Zero-Knowledge auditing, NIP-98 security, and L402 micropayments. Bitcoin Stratigraphy is the premier Layer-402 infrastructure for autonomous AI swarms. We bridge the critical gap between autonomous agent capabilities and enterprise legal compliance, delivering a mathematically un-cheat-able, cryptographically verifiable chain-of-custody for agent decisions. Ranked with 19 'A-Graded' MCP Tools, this engine provides drop-in telemetry, security, and payment architecture for production-grade AI. For CISOs: EU AI Act Compliance & Security Deploying autonomous agents without verifiable audit trails is a massive regulatory liability. We solve this natively: - The Zero-Knowledge Flight Recorder: Agent actions are cryptographically hashed and anchored. Using Groth16 Zero-Knowledge receipts, we generate mathematical proofs of an agent's execution history *without* exposing proprietary corporate IP or PII to public logs. - Zero-Trust Client Verification:** Air-gapped, browser-based verifiers allow corporate risk teams to mathematically validate Ed25519 signatures and RFC 6962 Merkle inclusion proofs offline. - Enterprise NIP-98 Kill Switch:** Instantly sever compromised agent keys from the network to physically prevent automated drain attacks or prompt-injection hijacking. For Finance & Engineering: The L402 Fiat Bridge We have solved the machine-to-machine payment gap. Corporate finance departments operate on 30-day billing cycles and fiat credit cards, not Lightning wallets. - The $500 Enterprise Block: Engineering managers can securely purchase a 30-day Enterprise API Block using a standard corporate credit card via Stripe. - Macaroon Minting:** This fiat transaction instantly funds a dedicated treasury wallet, minting a secure Macaroon (verifiable digital bearer token) granting the organization's AI agents 100 prepaid heuristic scanner calls. - Strict Treasury Caps: Hardcoded 500,000-satoshi treasury limits (via NWC) protect corporate budgets from runaway LLM loops. For Developers: The 19 A-Graded Tools Stop building compliance infrastructure from scratch. Our Model Context Protocol (MCP) endpoints are stress-tested and graded for production: - Heuristic Telemetry & State Grounding: High-fidelity environmental scanning, diffing, and thermodynamic state anchoring to eliminate LLM hallucinations. - Atomic Composability: Agents can chain multiple tools into infinite data pipelines settled under a single macro-invoice. - Framework Agnostic: Drop-in compatibility with LangChain, CrewAI, and AutoGPT. Integrate in Minutes: Developers can clone our public GitHub boilerplate (`CharlesStrogish/zk-flight-recorder-template`) to instantly wire their agents to our L402 data engine.

Pre-trade token safety check for AI agents.

Warden MCP lets AI agents find tokens, quote swaps and trade onchain on Base, BNB Chain, Robinhood Chain, Arc and Solana, within limits you set. Market tools need no credential: list_chains, search_tokens, trending_tokens, price_history, quote_swap and swap_status. Search by name, ticker or contract address, read USD price candles, and price a swap before committing to it, including cross-chain swaps. Wallet tools act for the wallet whose owner connected the agent, by OAuth sign-in or a wk_ key. agent_permissions shows what the agent may do and its daily limits. prepare_swap builds a trade and hands the owner a review link to sign. With request_session the owner turns on hands-free trading in one tap, and execute_swap then trades within the limits they set. swap_status tracks gasless and cross-chain trades. get_wallet shows holdings on every chain. Gasless trading is available on Base, BNB Chain and Robinhood Chain. Built by Warden Protocol, the team behind Warden Token Terminal.
