## Project Title

> **$500 / 7 Days: Football Betting Platform (Asian Market Only) – 4 Milestones, Source Code First Then Payment**

---

## Project Description

### Total Budget: $500 (Fixed Price)
### Total Timeline: 7 Days (from contract start)

**Payment Method:** 4 independent milestones. For each milestone, the freelancer **must deliver the complete source code first**. After the employer approves the delivery, the employer **will release the corresponding payment**.

**Core Rules:**
- No source code → No payment
- Incomplete source code → No payment
- Failed approval → No payment

---

## Scope of Work (Football & Asian Market Only)

- **Sports restriction:** Football only. All other sports categories must be completely removed.
- **Full-stack Python architecture:** Fully responsive user frontend (based on hga050 Google Tech UI style) and separate admin panel. Backend must be written in pure Python.
- **Multi-language login portal:** Must include a gateway login page with three language switchers at the top: Simplified Chinese, Traditional Chinese, and English. Must include login fields, "Remember Me", and "Forgot Password" options.
- **Asian market only:** Only Asian Handicap (AH) and Over/Under. Provide real-time odds/water line.
- **Live betting risk control:** Implement 3-8 second betting delay and automatic lock/rejection of bets during dangerous operations.
- **Data API and auto settlement:** Integrate a 100% free football data API. The system must automatically fetch final scores and auto-settle without manual intervention.
- **Auto wallet and account history:** Integrate payment wallet logic for automatic deposit/withdrawal. Must include a complete "Account History Overview" page showing transaction status, settlement history, credit history, and columns for date, bet amount, valid bet, win/loss record, with date filtering.

## Source Code Ownership Clause

> **For any payment the employer has released, the corresponding source code belongs to the employer. The freelancer may not refuse to deliver source code for paid milestones under the excuse of "full payment not yet received". The freelancer may not encrypt, obfuscate, or add backdoors to any delivered source code.**

| Milestone 3 not completed | $350 | Complete source code of Milestones 1+2 |
| Milestone 4 not completed | $450 | Complete source code of Milestones 1+2+3 |

**The employer will never be in a situation where payment is made but no corresponding source code is received.**

##双方确认 (Acknowledgment)

> **Employer confirms:** For each milestone, payment is released only after receiving the complete source code and approving it.
>
> **Freelancer confirms:** For each milestone, source code is delivered first. Payment is received before moving to the next milestone. If no source code is delivered, the employer has the right not to pay and bears no liability.
