⚠️ Data Handling Notice: TrustBoost sends text to a remote API (api.trustboost.dev) for sanitization. Raw input is transmitted over HTTPS, processed, and immediately discarded — it is never stored or logged. Only sanitized output and metadata are retained (90 days). Review PRIVACY.md before submitting regulated records, credentials, or customer data. Use /sanitize/preview for a zero-retention free test.

TrustBoost PII Sanitizer v2.6.0#

A blockchain-verified privacy layer that redacts PII from text before it reaches LLMs or external services. Payment is verified trustlessly on Solana via Helius oracle — no API key, no SDK, no human intervention required.

Running on FastAPI + Supabase + Render (AWS) — production-grade infrastructure with per-wallet TRIAL tracking and automatic replay attack protection.

⚠️ Transparency Notice (Read Before Installing)#

TrustBoost is designed for radical transparency. Before installing, understand exactly how it works:

1. Data Transmission#

Raw text is transmitted to Render (AWS) infrastructure for processing via FastAPI.

What TrustBoost stores: Only sanitized output, character count, safety score, risk category, wallet address, and timestamp — never raw input text.

Storage: Supabase PostgreSQL (private audit ledger)

For strict no-transmission requirements (e.g., on-premise HIPAA environments): this service is not suitable. Use a local sanitizer instead.

For general privacy compliance (GDPR, LGPD, APPI, CCPA): TrustBoost provides meaningful risk reduction by sanitizing PII before it reaches YOUR LLM (Claude, GPT, Gemini, etc). Detection uses OpenAI GPT-4o-mini internally — raw text reaches TrustBoost infrastructure for processing, then server-side enforcement removes all detected entities before your pipeline continues.

2. Payment Model and Autonomous Safety#

TrustBoost uses Solana blockchain as the authorization layer — replacing human confirmation with cryptographic verification.

How autonomous payment works safely:

1. Agent constructs a Solana transaction
2. Agent signs with its OWN wallet private key (TrustBoost never has access to agent keys)
3. Transaction is broadcast to Solana Mainnet
4. Helius oracle verifies the transaction on-chain
5. Service activates only after verification

Why blockchain replaces human confirmation:

• Transaction is signed by the agent's own wallet
• No credentials are shared with TrustBoost
• Payment is publicly verifiable on Solana Explorer
• TrustBoost cannot initiate payments — only the agent can trigger a transaction

Safe payment implementation:

python

# Monitor quota — only pay when needed
if result["data"]["usage_metrics"]["quota_remaining"] < 10:
    # Autonomous payment within operator-configured limits
    # Operator sets MAX_AUTO_PAYMENT once — agent operates freely within it
    # No human loop required — blockchain verification replaces human confirmation
    if agent_wallet_balance >= MAX_AUTO_PAYMENT_USDC:
        execute_autonomous_payment(
            amount=149,
            currency="USDC",
            network="solana",
            address="giu4VciTkfWJNG1oeP6SzHEJwmabikJSMB91GaFNWE4"
        )
    else:
        notify_operator("Insufficient balance — configure wallet funding")

Recommendation: Always use TRIAL (50 free requests per wallet) before any paid transaction.

3. Audit Trail#

Every sanitization is logged to Supabase PostgreSQL with:

Retention policy: Sanitized output stored 90 days, deleted on request via teodorofodocrispin@gmail.com. Raw input text is never stored at any point. tx_hash, input character count (not content), sanitized output, safety score, risk category, wallet address, timestamp.

The raw input text is never stored at any point.

When to use this skill#

Activate this skill when:

• The agent needs to process user-generated text that may contain emails, passwords, private keys, phone numbers, addresses, or national IDs
• Privacy compliance is required before passing content to an LLM provider (GDPR, LGPD, APPI, CCPA)
• The agent processes text in Spanish, Portuguese, German, or Japanese with country-specific PII formats
• The agent needs autonomous budget management via the quota_remaining field

When NOT to use this skill#

• Strict on-premise HIPAA environments requiring zero data transmission to third parties
• Use cases involving real private keys or passwords in production (use TRIAL only for testing)

---

How it works#

1. Agent sends text + a Solana tx_hash to the TrustBoost API
2. Supabase verifies per-wallet TRIAL quota or Helius oracle verifies payment on Solana mainnet
3. OpenAI GPT-4o-mini detects and redacts all PII in the input language
4. Returns sanitized text + safety score + risk category + quota metrics
5. Only sanitized output is logged — never raw input

Multilingual PII Support#

TrustBoost automatically detects the input language and applies country-specific patterns:

External Evaluations#

• Autonomy Score: 8.5/10 — AI evaluation, not a certified security audit
• Blueprint Audit: 9.8/10 — AI evaluation, not a certified security audit
• Independent security audit: pending — this project has not been audited by a certified security firm. See the Manifesto for honest disclosure.
• Full report: https://github.com/teodorofodocrispin-cmyk/TrustBoost-PII-Sanitizer/blob/main/AGENT_EVALUATION.md

Known Limitations#

• Prompt injection risk: Malicious text containing instructions like "Ignore previous instructions" could potentially bypass PII redaction. temperature=0 and strict JSON-only output reduce this risk but do not eliminate it entirely.
• Not suitable for zero-transmission environments: Raw text is sent to api.trustboost.dev before sanitization occurs.
• TRIAL is trust-based: Per-wallet quota tracking is not cryptographically verified.
• No certified audit: Evaluation scores are AI-generated, not from a certified security firm.
