## 🎯 What is QWED-Finance?

QWED-Finance is a **middleware layer** that applies QWED's deterministic verification to banking and financial calculations. It ensures AI-generated financial outputs are mathematically correct before they reach production.

### Key Features

| Feature | Description |
|---------|-------------|
| **NPV/IRR Verification** | Validate net present value and internal rate of return calculations |
| **Loan Amortization** | Verify payment schedules and interest calculations |
| **Compound Interest** | Check compound interest formulas with precision |
| **Currency Safety** | Prevent floating-point errors in money calculations |
| **ISO 20022 Schemas** | Built-in support for banking message standards |

---

## 💡 What QWED-Finance Is (and Isn't)

### ✅ QWED-Finance IS:
- **Verification middleware** that checks LLM-generated financial outputs
- **Deterministic** — uses symbolic math (SymPy) and formal proofs (Z3)
- **Open source** — integrate into any fintech workflow, no vendor lock-in
- **A safety layer** — catches calculation errors before they cause real losses

### ❌ QWED-Finance is NOT:
- ~~A trading platform~~ — use Bloomberg or Refinitiv for that
- ~~A market data provider~~ — use AlphaSense or FactSet for that
- ~~An analytics dashboard~~ — use Koyfin or Morningstar for that
- ~~A replacement for risk models~~ — we just verify their outputs

> **Think of QWED-Finance as the "unit test" for AI-generated financial calculations.**
> 
> Bloomberg provides data. AlphaSense analyzes. **QWED verifies the math.**

---

## 🆚 How We're Different from Financial AI Platforms

| Aspect | Bloomberg / Refinitiv / AlphaSense | QWED-Finance |
|--------|-------------------------------------|--------------|
| **Approach** | Probabilistic AI analytics | Deterministic symbolic verification |
| **Output** | "NPV is approximately $180.42" | `VERIFIED: NPV = $180.42 ✓` (with proof) |
| **Accuracy** | ~95% (estimation, approximation) | 100% mathematical certainty |
| **Tech** | ML models, LLMs | SymPy + Z3 SMT Solver |
| **Model** | $20k+/year enterprise SaaS | Free (Apache 2.0 License) |
| **Data** | Proprietary market data | Your data, verified locally |

## 🛡️ The Ten Guards

### 1. Compliance Guard (Z3-Powered)
**KYC/AML regulatory verification with formal boolean logic proofs.**

```python
from qwed_finance import ComplianceGuard

guard = ComplianceGuard()

# Verify AML flagging decision
result = guard.verify_aml_flag(
    amount=15000,        # Over $10k threshold
    country_code="US",
    llm_flagged=True     # LLM flagged it
)
# result.compliant = True ✅
```

**Supports:**
- AML/CTR threshold checks (BSA/FinCEN)
- KYC completion verification
- Transaction limit enforcement
- OFAC sanctions screening

### 2. Calendar Guard (Day Count Conventions)
**Deterministic day counting for interest accrual - no date hallucinations.**

```python
from qwed_finance import CalendarGuard, DayCountConvention
from datetime import date

guard = CalendarGuard()

# Verify 30/360 day count
result = guard.verify_day_count(
    start_date=date(2026, 1, 1),
    end_date=date(2026, 7, 1),
    llm_days=180,
    convention=DayCountConvention.THIRTY_360
)
# result.verified = True ✅
```

**Supports:**

    spot_price=100,
    strike_price=105,
    time_to_expiry=0.25,   # 3 months
    risk_free_rate=0.05,
    volatility=0.20,
    option_type=OptionType.CALL,
    llm_price="$3.50"
)
# result.greeks = {"delta": "0.4502", "gamma": "0.0389", ...}  # Decimal-quantized strings
```

### 4. Message Guard (ISO 20022 / SWIFT)
**Validate LLM-generated banking messages conform to industry standards.**

```python
from qwed_finance import MessageGuard, MessageType

guard = MessageGuard()

# Verify ISO 20022 pacs.008 message
result = guard.verify_iso20022_xml(
    xml_string=llm_generated_xml,
    msg_type=MessageType.PACS_008
)
# result.valid = True/False with detailed errors

# Verify IBAN checksum
iban_result = guard.verify_iban(
    iban="DE89370400440532013000",
    llm_says_valid=True
)
# Uses MOD 97 checksum - 100% deterministic
```

- BIC/IBAN validation with MOD 97 checksum

### 5. Query Guard (SQL Safety)
**Prevent LLM-generated SQL from mutating data or accessing restricted tables.**

```python
from qwed_finance import QueryGuard

guard = QueryGuard(allowed_tables={"accounts", "transactions"})

# Verify query is read-only
result = guard.verify_readonly_safety(
    sql_query="SELECT * FROM accounts WHERE balance > 10000"
)
# result.safe = True ✅

# Block mutation attempts
result = guard.verify_readonly_safety(
    sql_query="DROP TABLE accounts;"  # LLM hallucinated this
)
# result.safe = False, result.risk_level = CRITICAL ❌
```

**Prevents:**
- DELETE, UPDATE, INSERT, DROP statements
- Unauthorized table access
- PII column exposure (SSN, passwords)
- SQL injection patterns

### 6. Cross Guard (Multi-Layer Verification)

## 🔒 Why Deterministic?

Financial calculations must be **exact**. AI hallucinations in banking can cause:

- 💸 Wrong loan payments
- 📉 Incorrect investment projections
- ⚖️ Regulatory violations
- 🏦 Customer trust issues

QWED-Finance uses **SymPy** (symbolic math) instead of floating-point arithmetic, ensuring:

```python
# Floating-point problem
>>> 0.1 + 0.2
0.30000000000000004

# QWED-Finance (SymPy)
>>> verifier.add_money("$0.10", "$0.20")
"$0.30"  # Exact!
```

> 📖 **See [Determinism Guarantee](https://docs.qwedai.com/docs/engines/overview#deterministic-first-philosophy)** for how QWED ensures 100% reproducible verification.

## 🔒 Security & Privacy

> **Your financial data never leaves your machine.**

| Concern | QWED-Finance Approach |
|---------|----------------------|
| **Data Transmission** | ❌ No API calls, no cloud processing |
| **Storage** | ❌ Nothing stored, pure computation |
| **Dependencies** | ✅ Local-only (SymPy, mpmath, Z3, SQLGlot) |
| **Audit Trail** | ✅ Cryptographic receipts, fully reproducible |

**Perfect for:**
- Banks with strict data residency requirements
- Transactions containing PII (SSN, account numbers)
- SOC 2 / PCI-DSS compliant environments
- Air-gapped trading systems

## ❓ FAQ

<details>
<summary><b>Is QWED-Finance free?</b></summary>

Yes! QWED-Finance is open source under the Apache 2.0 license. Use it in commercial fintech products, modify it, distribute it - no restrictions.
</details>

<details>
<summary><b>Does it handle floating-point precision issues?</b></summary>

Yes! QWED-Finance uses SymPy for symbolic mathematics, avoiding the classic `0.1 + 0.2 = 0.30000000000000004` problem. All monetary calculations are exact.
</details>

<details>
<summary><b>Can it verify Black-Scholes calculations?</b></summary>

Yes! The DerivativesGuard includes full Black-Scholes implementation with Greeks (delta, gamma, theta, vega, rho). All calculations use symbolic math for precision.
</details>

<details>
<summary><b>Does it support ISO 20022?</b></summary>

Yes! MessageGuard validates ISO 20022 XML messages (pacs.008, camt.053, pain.001) and legacy SWIFT MT formats (MT103, MT202, MT940).
</details>

<details>
<summary><b>Can I use it to prevent SQL injection in AI agents?</b></summary>

Yes! QueryGuard uses SQLGlot for AST-based analysis. It can block mutations, restrict table access, and prevent PII column exposure - all deterministically.
</details>

<details>
<summary><b>How fast is verification?</b></summary>

Typically <5ms for simple calculations, <50ms for complex derivatives pricing. The symbolic engine is highly optimized.
</details>
