Overview

The HITBNB Vault is a smart contract that securely manages reward allocations, token distributions, pending withdrawals, and claim functions for users in the HITBNB ecosystem. It serves as a central hub (it's works decentralized no central control for any transaction ) where all automated and user-initiated token claims are executed.

🔐 Key Responsibilities

• Holding HITBNB tokens for monthly ROI, staking, and reward purposes

• Managing pending claims set by the backend logic (after calculations)

• Ensuring secure and gas-optimized withdrawals by users

• Facilitating automated top-holder reward releases (Chainlink Functions)

🔁 Fund Flow

1. Tokens enter the vault from the ROI Wallet.

2. Dapp Back-end sets pending rewards or ROI for a user.

3. User claims through the Web3 UI → claimTokens() function.

4. HITBNB is transferred from Vault to the user’s wallet.

🔧 Core Functions

• setPendingWithdrawal(address user, uint256 amount) Sets the user’s pending amount available for claim. Callable only by backend/admin.

• claimTokens() Lets user claim their assigned HITBNB rewards. Automatically transfers to connected wallet.

• getPendingAmount(address user) View function to check how much HITBNB a user can claim.

🔒 Security Measures

• Only whitelisted HITBNB dApp wallets can set pending balances

• Claimable amounts are stored in mappings and not released until the user initiates a claim

• Vault holds HITBNB in custody until explicitly distributed to ensure automation compatibility

⚙️ Integration Points

• Chainlink Keepers connects to Vault for setting claimable amounts monthly

• HITBNB dApp shows claimable balances and triggers claim transactions

• Chainlink Automation : For top holder monthly reward releases

🧪 Sample Flow

USDT → HITBNBBuyer → Buys HITBNB → Sent to ROI Wallet
             ↓
        ROI Wallet → HITBNB Vault (if needed)
             ↓
     Admin sets: setPendingWithdrawal(user, 1000)
             ↓
     User visits dashboard → Clicks "Claim"
             ↓
     HITBNB Vault sends 1000 HITBNB to user

📌 Notes

• Vault must always be sufficiently funded buy chainlink automation from ROI Wallet

• Tokens are not claimable unless explicitly marked as pending

• Vault helps decouple calculation logic from distribution, improving scalability and modularity
