Source code verification provides a way for projects to open source their smart contract code for end users to inspect and verify that it does what it claims to do. By uploading source code, BscScan will match the compiled contract bytecode with that on the blockchain and display it under the Contract Four Nine X Ai is a standard code on BNB Smart Chain (BSC), BEP20 guarantees lower transaction costs stable and fast transactions with the goal of providing a flexible format for developers

Audit by AI (Four Nine X Ai)

✅ Key Features and Functions

1. Standard ERC20 Implementation

   • Implements IERC20, IERC20Metadata

   • Supports transfer, approve, transferFrom, increaseAllowance, decreaseAllowance

2. Owner Control

   • Inherits from Ownable, restricting rescueBalance, rescueToken, transferOwnership to the owner.

3. Token Supply Initialization

   • On deployment, _mint(owner(), _totalSupply * 10^_decimals) is called to allocate total supply.

4. Burn Function

   • burn(uint256 amount) allows any token holder to destroy their own tokens.

5. Token Rescue

   • rescueToken(...): allows the owner to withdraw any ERC20 token sent to the contract.

   • rescueBalance(...): allows the owner to withdraw native BNB from the contract.

6. Service Fee Payment

   • The contract calls an external payServicesFees() function on deployment to pay for Makecoin services (used by ServicePayer constructor).

   • Referral support via _refaddress.

⚠️ Security Risks & Warnings

Area	Issue / Concern
rescueToken	Owner can withdraw any ERC20 tokens sent to the contract.
rescueBalance	Owner can withdraw all BNB from the contract.
burn	Functionally safe, but should be double-checked if you're implementing tokenomics.
Ownership	renounceOwnership() can remove owner, disabling privileged functions forever.
External Call	Constructor calls payServicesFees() — ensure the receiver contract is trusted.

🛠️ Suggestions for Improvement

1. Blacklist or Pause Functionality

   • Add Pausable or Blacklistable modifiers to restrict token operations during emergencies.

2. Emit Events for Rescue

   • Emit custom events in rescueToken() and rescueBalance() for better transparency.

3. Gas Optimization

   • Use SafeERC20 (from OpenZeppelin) to handle ERC20 token transfers safely, especially for non-standard tokens.

4. Constructor Comments

   • Document the parameters clearly, especially _servicePayer, _servicesName, and _refaddress.

5. Security Audit

   • If you plan to go live with real value, get the contract audited to verify the external service call behavior.

🔐 Summary of Access Control

Function	Access	Action
burn()	Public	Burns sender's tokens
rescueBalance()	OnlyOwner	Withdraws native BNB
rescueToken()	OnlyOwner	Withdraws ERC20 tokens
transferOwnership()	OnlyOwner	Changes contract owner

🧪 Final Verdict

✅ Safe for general use as a standard ERC20 token, 🔒provided:

• You trust the service payer contract being called in the constructor.

• You understand the owner has strong control over the funds held in the contract.
