## Phase 1: Audit Before You Sign

Upload your contract (PDF or paste text). In under 30 seconds, ContractGuard's QVAC AI gives you a complete analysis.

**What the AI checks:**

### Fairness Score (1–10)

A single number that tells you how balanced the contract is — before you sign a word.

| Score | Meaning               | Action                 |
| ----- | --------------------- | ---------------------- |
| 8–10  | Fair for both parties | Safe to proceed        |
| 5–7   | Concerns present      | Review flagged clauses |
| 1–4   | Significant imbalance | Request revisions      |

### Risky Clauses

Every clause that could hurt you is flagged with exact text, the reason it's risky (in plain language), and a specific revision suggestion grounded in Indonesian law.

### Market Price Comparison

Every line item is compared against real Indonesian market data pulled from Blibli, Google Shopping, and other sources via the FastAPI backend.

> *"Server hosting: Rp 15,000,000/month — market rate is Rp 4,000,000–7,000,000. Significantly overpriced."*

### Regulation Compliance

The AI checks your contract type against Indonesian laws and flags any non-compliance — specific article, specific issue.

***

## Phase 2: Deploy On-Chain

Once the contract is agreed and audited, deploy it to Solana in one click.

**What happens on-chain:**

1. Client's USDC transfers into a **smart contract escrow** — locked, inaccessible to either party
2. The audit hash is recorded on-chain — cryptographic proof the contract was reviewed
3. Both wallets are registered — no central authority, no escrow service fees

> **Nobody can touch the money until milestones are verified. Not the client. Not the contractor. Not ContractGuard.**

***

## Phase 3: Verify Milestones & Release Funds

When the contractor finishes a milestone, they upload evidence files and a description directly in the dashboard.

**The QVAC AI reviews evidence automatically:**

* Reads evidence files from local storage at `D:\frontier\evidence\{pdaAddress}\{checkpointIndex}\`
* Cross-references with the original contract PDF stored at `D:\frontier\evidence\{pdaAddress}\contract\`
* Returns a compliance score (0–100) and specific findings
* Verdict: `APPROVED`, `NEEDS REVISION`, or `MAJOR ISSUE`

**When the client approves:**

* One click → one Solana transaction
* Funds release instantly to the contractor's wallet
* No waiting period, no bank transfer delays, no dispute middleman
