💻7. Fairness & Security

✅ Zero-trust, on-chain verified, anti-manipulation lottery protocol

7.1 Our Commitment: Don’t Trust, Verify

In traditional lotteries, fairness must be trusted. In Lucky 45, fairness can be verified.

All gameplay, data processing, and fund distribution follow four trustless principles:

• ✅ On-chain transparency

• ✅ Auditable algorithms

• ✅ Traceable processes

• ✅ Non-custodial asset control

No single party — not even the platform — can influence outcomes. Fairness is provable by code.

7.2 Draw System: Multi-Source, Verifiable Randomness

Lucky 45 uses a hybrid draw formula:

Winning Number = keccak256(Ethereum Block Hash + Chainlink VRF + Platform Salt)

✅ Component Advantages:

Source	Function
Ethereum Block Hash	Base-layer unpredictability; not manipulable
Chainlink VRF	Verifiable randomness from decentralized oracle
Platform Salt	Extra entropy; resists pre-image attacks
keccak256 Output	Final result; deterministic, tamper-proof, fully reproducible

📌 Verification Method:

• All draw data recorded on-chain via public smart contracts

• Users can replay and verify each draw via blockchain explorers

• Anyone can validate inputs and check outcome correctness

✅ The draw process = the result = the proof of fairness.

7.3 Transparent Prize Pool & Payout Distribution

• All bets, fees, and reward logic are 100% on-chain

• Prize pool evolution (rollover, allocation, locking) is viewable in real-time

• Winner payouts are direct, automated, and linked to wallet addresses

📌 Lucky 45 team cannot interfere with results or payouts — ever.

7.4 User Asset Safety

Lucky 45 never holds user funds. All assets reside in user-controlled wallets, with automated payout execution.

Component	Security Design Description
Account Wallets	Custodial wallets created per user; non-transferrable by platform
Deposits / Withdrawals	User-initiated via on-chain flows with multi-step authentication
Bet Execution	Wagers are locked via smart contracts — no manual handling
Reward Payouts	Fully automated to user wallet; can be withdrawn anytime

🧾 For light wallets (e.g., Telegram Wallet), one-click private key export ensures user sovereignty.

7.5 Anti-Cheating & Risk Controls

To maintain a level playing field, Lucky 45 enforces multi-layer anti-abuse systems:

Risk Area	Detection Strategy
Multi-accounting	Fingerprint/IP/device clustering to prevent farms/bots
Referral Exploits	Flags fake/inactive team abuse in invite systems
High-Frequency Abuse	Detects abnormal betting patterns or flash farming behavior
Card Drop Tampering	RNG logic is on-chain; client-side inputs cannot affect drop

📌 All penalties (bans, point freezes, etc.) are traceable via on-chain logs.

---

7.6 Security Audits & Code Transparency

🔐 Audit Plan by Module:

Module	Audit Status
Draw Logic	Integrated with Chainlink VRF (audited component)
Prize Pool	Based on public standards; full audit scheduled (e.g., Certik)
Wallet Contracts	Modular contracts; white-box tested internally
Points/Card System	Final audit before token launch

• Smart contracts will be open-sourced on GitHub

• Bug bounty program planned to ensure long-term security

---

7.7 Legal Compliance & Regional Access Controls

Lucky 45 enforces jurisdictional compliance through layered restrictions:

Control Area	Description
Region Restrictions	Access blocked via IP/timezone (e.g., Mainland China)
User Disclaimers	Participation gated by eligibility confirmation
Payout Restrictions	High USDT claims may require KYC or delay
Terms Acceptance	All actions tied to user agreement, time-stamped on-chain

📌 Lucky 45 does not operate in regions where lottery systems are prohibited by law.
