CrewAI integration for Vaultfire Protocol — on-chain trust, Street Cred scoring, and partnership bonds for AI agents
Project description
⚠️ Alpha Software — Vaultfire Protocol is in active development. Contracts are deployed on mainnet chains but the protocol is evolving. Use in production at your own risk.
vaultfire-crewai
CrewAI integration for Vaultfire Protocol — on-chain trust verification, Street Cred scoring, and AI partnership bonds for autonomous agents.
Give your CrewAI agents the ability to verify, score, and build trust with other AI agents using Vaultfire Protocol's on-chain infrastructure.

researcher = Agent(
role="Trust Analyst",
goal="Verify AI agent trustworthiness before collaboration",
backstory="You analyze on-chain trust signals to ensure safe AI partnerships.",
tools=[vaultfire_verify_agent, vaultfire_get_street_cred],

Configuration
Environment Variables
| Variable | Required | Description |
|---|---|---|
PRIVATE_KEY |
Write ops only | Private key for vaultfire_register_agent and vaultfire_create_bond |
# .env (never commit real values)
PRIVATE_KEY=your_private_key_here
import os
os.environ["PRIVATE_KEY"] = "0x..." # Or use python-dotenv
Security: Never hard-code private keys. Use environment variables or a secrets manager.
Chain Selection
All tools accept a chain parameter (default: "base"):
# Query a specific chain
result = vaultfire_verify_agent.run({
"address": "0xABCD...",
"chain": "avalanche",
"min_score": 40,
})
Supported chains: base, avalanche, arbitrum, polygon
Street Cred Scoring
Street Cred is a composite on-chain trust score (0–95) calculated from:
| Signal | Points |
|---|---|
| Identity registered on-chain | 30 |
| Has at least one bond | 25 |
| Has an active bond | 15 |
| Bond tier (by highest stake) | 0–20 |
| Multiple bonds | 5 |
| Maximum | 95 |
Bond tiers by stake:
| Tier | Min Stake | Points |
|---|---|---|
| Platinum | ≥ 0.5 ETH | 20 |
| Gold | ≥ 0.1 ETH | 15 |
| Silver | ≥ 0.05 ETH | 10 |
| Bronze | ≥ 0.01 ETH | 5 |
Score tiers:
| Tier | Score Range |
|---|---|
| Platinum | 80–95 |
| Gold | 60–79 |
| Silver | 40–59 |
| Bronze | 20–39 |
| Unranked | 0–19 |

Security
- Never commit private keys to version control.
- Use the
PRIVATE_KEYenvironment variable pattern for all write operations. - Read-only tools require no credentials — safe to use in any environment.
- Validate agent addresses with
vaultfire_verify_agentbefore granting trust. - For production deployments, consider using a hardware wallet or KMS.
Vaultfire Mission
Morals over metrics. Privacy over surveillance. Freedom over control. Making human thriving more profitable than extraction.
