🌐 Website Security (Front-End)

1. Is the website generally secure?

✅ YES — High Security Level

The site is hosted on GitHub Pages which uses HTTPS by default, encrypting all communication between user browser and server.

Review of dapp.html shows no fetch or XMLHttpRequest requests to external servers for transaction processing.

                // From dapp.html - All transactions go directly to blockchain
                const tx = await fitTokenContract.Buy(buyer, amountWei);
                await tx.wait();
            

2. Does the site have access to my wallet?

❌ NO — The site never has direct access to your wallet

Wallet connection uses the standard eth_requestAccounts method which only provides the public address and never has access to private keys.

                // From dapp.html
                async function connectWallet() {
                    if (typeof window.ethereum !== 'undefined') {
                        await window.ethereum.request({ method: 'eth_requestAccounts' });
                        await initContracts(window.ethereum);
                    }
                }
            

3. Can the site endanger my assets?

❌ NO — No risk to user assets

Review shows the only functions for interacting with the contract are: approveNetworkDAI, approveTokenDAI, becomeOwner, buyFIT, sellFIT, joinGiftContract, and freeGift.

No function exists for automatic token transfers. Every transaction requires manual user confirmation in the wallet.

4. Is my recovery phrase at risk?

❌ NO — Recovery phrase is never stored or requested

Review of all HTML files shows no input field for recovery phrase (Seed Phrase/Mnemonic).

Only language settings are stored in localStorage. No sensitive information is ever stored.

5. Are there hidden buttons or functions?

❌ NO — No hidden or backdoor functions exist

All buttons have clear, transparent functionality. All functions require user confirmation in the wallet.

6. Does the site store my information?

✅ Only non-sensitive information is stored

Items stored: Language settings and calculation history only.

Items NOT stored: Wallet address, wallet balance, transaction history, private keys, recovery phrase.

🔗 Smart Contract Security

1. Can DAI liquidity be drained from the contract?

❌ NO — No liquidity drain access exists

Review of Fly_Infinity_Token.sol shows the transfer, transferFrom, and approve functions are DISABLED.

                // From Fly_Infinity_Token.sol
                function transfer(address to, uint256 amount) public override returns (bool) {
                    require(false, "Transfers are disabled. Use buy/sell only");
                    return super.transfer(to, amount);
                }
                
                function transferFrom(address owner, address spender, uint256 amount) public override returns (bool) {
                    require(false, "Transfers are disabled. Use buy/sell only");
                    return super.transferFrom(owner, spender, amount);
                }
            

No function exists for direct DAI withdrawal. The only way for DAI to leave is through the Sell function.

2. Can Founder withdraw user funds?

❌ NO — Founder has no access to user assets

No modifier named onlyFounder or onlyOwner exists in the token contract.

                // From Fly_Infinity_Token.sol - No onlyFounder modifier found
                // Only DAO can change the network
                modifier onlyDAO() {
                    require(msg.sender == daoContract, "Only DAO can call this");
                    _;
                }
            

3. Can the price decrease?

✅ Price NEVER decreases (Non-Diminishing)

The price formula is:

                // From Fly_Infinity_Token.sol
                function Price() public view returns (uint256) {
                    if (totalSupply() == 0) return 1e18;
                    return DAI.balanceOf(address(this)) * 1e18 / totalSupply();
                }
            

Mathematical proof shows price increases on both BUY and SELL transactions:

Buy: New price = (R + m) / (S + 0.97m/P) > P ✅
Sell: New price = (R - 0.94P) / (S - 1) > P ✅
Buy Fee (3%): Increases reserve → price increases
Sell Fee (6%): Increases reserve → price increases

4. Are there purchase limits?

✅ Yes — Anti-Whale Security Mechanism

Purchase limits are calculated based on network activity:

                // From Fly_Infinity_Token.sol
                function Calculate_Purchase_Limit(address user) public view returns (uint256) {
                    (uint32 allLeft, uint32 allRight) = flyInfinityNetwork.Owner_Left_Right_All(user);
                    uint32 minSide = allLeft < allRight ? allLeft : allRight;
                    
                    uint256 totalLimit = 100 * 1e18;  // Starts at 100 DAI
                    
                    if (minSide >= 1) totalLimit += 100 * 1e18;
                    if (minSide >= 10) totalLimit += 100 * 1e18;
                    if (minSide >= 30) totalLimit += 100 * 1e18;
                    // ... continues with higher tiers
                    
                    return totalLimit;
                }
            

🏛️ DAO Governance Analysis

How does the DAO voting system work?

✅ Complete Decentralized Voting Process

The DAO system implements a 3-day voting period for network members to decide on major changes.

                // From Fly_Infinity_DAO.sol
                enum ProposalType {
                    CHANGE_NETWORK_ADDRESS,
                    CHANGE_GIFT_ADDRESS
                }
                
                enum ProposalStatus {
                    Active,
                    Executed,
                    Rejected,
                    Expired
                }
            

Proposal Lifecycle:

Founder submits proposal
3-day voting period begins
Network members vote (Support/Oppose)
If Support > Oppose → Proposal executed with automatic fund migration
If Oppose > Support → Proposal rejected

What are the security benefits of the DAO?

Feature	Description	Security Benefit
3-day Voting Period	Time to review proposals	Prevents rushed decisions
Valid Voters Only	Only network members can vote	Prevents Sybil attacks
One Vote Per User	Fair and non-manipulable	Democratic and transparent
Automatic Fund Migration	Self-executing transfer	Prevents fund theft
Full Blockchain Recording	All votes visible	Complete transparency
Limited Proposals	Only Founder can propose	Prevents spam
