🛡️ 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, national IDs, crypto wallets
Audit logging | Saves every operation to Supabase PostgreSQL for traceability

Why Solana?

Agents transact with each other without humans. Solana is fast, cheap, and Helius API makes verification simple. And now — every paid sanitization is anchored on-chain. Proof that cannot be falsified.

How to Test It (50 Free Requests Per Wallet)

curl -X POST "https://api.trustboost.dev/sanitize" \
-H "Content-Type: application/json" \
-d '{
"tx_hash": "TRIAL",
"wallet_address": "your_wallet",
"text": "My email is john@doe.com and my AWS key is AKIAIOSFODNN7EXAMPLE"
}'

Response:

{
"status": "success",
"data": {
"sanitized_content": "My email is [REDACTED] and my AWS key is [REDACTED]",
"safety_score": 0.85,
"risk_category": "CRITICAL",
"context_applied": "general",
"usage_metrics": {
"quota_remaining": 49,
"quota_limit": 50
}
}
}

Proof of Sanitization on Solana (NEW in v2.6.0)

Every paid sanitization returns an immutable on-chain proof:

{
"proof_of_sanitization": {
"solana_tx": "abc123...",
"verify_url": "https://solscan.io/tx/abc123...",
"description": "Immutable proof anchored on Solana mainnet"
}
}

Verify any sanitization independently:
GET https://api.trustboost.dev/verify/{anchor_tx}

Context-Aware Sanitization (NEW in v2.5.0)

curl -X POST "https://api.trustboost.dev/sanitize" \
-H "Content-Type: application/json" \
-d '{
"tx_hash": "TRIAL",
"wallet_address": "your_wallet",
"text": "RFC: LOPJ850101ABC, monto: $50,000",
"context": "financial"
}'
