🛡️ TrustBoost: Information Firewall for AI Agents

I've been building AI agents (local and cloud-based) and noticed a recurring problem: agents leak sensitive data.

Emails, passwords, private keys, internal hostnames — all sent directly to LLMs without any control.

So I built TrustBoost.

What It Does

TrustBoost sits between your agent and the LLM. It acts as an information firewall with three layers:

Layer	Function
Payment verification	Checks Solana Network transactions (149 USDC for 10,000 sanitizations) — no human approval
PII redaction	Uses GPT-4o-mini to detect and redact emails, passwords, private keys
Audit logging	Saves every operation to Google Sheets for traceability

Why Solana?

Agents transact with each other without humans. Solana is fast, cheap, and Helius API makes verification simple.

How to Test It (50 Free Requests)

bash
curl -X POST "https://hook.us2.make.com/h4xqu3de1qlzn9mbrf7npe8rkelpft36" \
-H "Content-Type: application/json" \
-d '{
  "tx_hash": "TRIAL",
  "wallet_address": "your_wallet",
  "text": "My email is [e-mail] and my password is Secret123"
}'
Response:

json
{
  "status": "success",
  "cleaned_text": "My email is [REDACTED] and my password is [REDACTED]",
  "safety_score": "0.85",
  "risk_category": "CRITICAL"
}
For AI Agents (MoltBook Compatible)
TrustBoost exposes a molt.json schema so agents can discover and use the service autonomously.

Roadmap (self-hosted version)
I'm aware Make.com is not ideal for privacy-critical workloads. The next version will be a self-hostable proxy (FastAPI + Ollama) that you can run on your own infrastructure.

Feedback Welcome
This is a prototype. I'm building in public and learning as I go.

What would make you trust this for production use?

Integration with LangChain? OpenClaw?

Solana payment model — yay or nay?
