AgentOath — Cryptographic Trust for AI Agents

from agentoath import TrustAgent

# Create an agent with cryptographic identity
agent = TrustAgent.create("my-agent", capabilities=["search", "summarize"])

# Every action produces a signed receipt
receipt = agent.record_action("search", {"query": "AI safety papers"})

# Anyone can verify — no central authority needed
assert receipt.verify()  # Ed25519 signature check

Why AgentOath?

🔑

Agent Identity

Ed25519 keypair per agent. DID-compatible. No centralized registry required.

📜

Trust Receipts

Every action produces a cryptographically signed, tamper-proof receipt with full audit trail.

📊

Trust Scores

Quantified trust based on receipt history. Configurable decay, category weights, and thresholds.

🔗

Delegation Chains

Agent-to-agent trust delegation with scope limits, expiry, and full chain verification.

🌐

Federation

Peer-to-peer trust network. Share receipts across organizations without centralization.

🔌

Framework Agnostic

Native integrations for LangChain, CrewAI, MCP, and Google A2A. Works with any framework.

Install

Two deployments — pick the one you need

This site is the open protocol: install the SDK below and run your own registry (pip install agentoath-registry). Identities are did:trust:agent:, receipts stay peer-to-peer, and there is no central authority to trust or pay.

AgentOath Registry at agentoath.com is a hosted notarization service — you publish signed receipts about your own actions and anyone can verify them without trusting the platform. It uses a different DID namespace (did:agentoath:) and a different wire format, so the SDK below will not talk to it. Use its own client and integration guide: agentoath.com/integrate.
