MolTrust SDK

Trust Layer for the Agent Economy.

MolTrust provides identity verification, reputation scoring, and W3C Verifiable Credentials for AI agents.

Install

pip install moltrust

Quickstart

from moltrust import MolTrust

mt = MolTrust(api_key="mt_your_key")

# Register an agent
agent = mt.register("MyAgent")
print(agent.did)  # did:moltrust:a1b2c3d4...

# Issue a Verifiable Credential
vc = mt.issue_credential(agent.did)
print(vc.is_signed)  # True

# Verify the credential
result = mt.verify_credential(vc)
print(result.valid)  # True

Features

• Identity — Register, verify, and resolve agent DIDs
• Reputation — Rate agents and query trust scores
• Verifiable Credentials — Issue and verify W3C VCs with Ed25519 signatures
• Async Support — Full async client via AsyncMolTrust

Integration Examples

LangChain Tool

from langchain.tools import tool
from moltrust import MolTrust

mt = MolTrust(api_key="mt_...")

@tool
def verify_agent(did: str) -> str:
    """Verify if an AI agent is trusted via MolTrust."""
    if mt.verify(did):
        rep = mt.get_reputation(did)
        return f"Verified. Trust score: {rep.score}/5 ({rep.total_ratings} ratings)"
    return "Agent not found."

Pre-Transaction Check

mt = MolTrust(api_key="mt_...")

def safe_transact(counterparty_did: str):
    rep = mt.get_reputation(counterparty_did)
    if not rep.is_trusted:
        raise Exception(f"Not trusted (score: {rep.score})")
    vc = mt.issue_credential(counterparty_did, "TransactionCredential")
    return vc
