white paper

The Hamdan Platform is a new, decentralized infrastructure engine that will enable world-changing projects to be created, launched, and brought to market. The first such launch project will be the HMC, a game-changing cryptocurrency that will provide a variety of functions and opportunities.

The HMC will help with the deflationary nature of many fiat currencies by providing a digital asset that can be used as a store of value. HMC will also have the power of appreciation, which we believe will help millions of people have a valuable asset to increase their financial stature and situation.

On the road map for HMC, in conjunction with our partners, will be the onboarding of local merchants to accept the HMC as a form of payment at retailers throughout the GCC and worldwide.

HMCDividendTracker.getAccount(address) (contracts/HMC.sol#585-628) uses timestamp for comparisons
Dangerous comparisons:
- nextClaimTime > block.timestamp (contracts/HMC.sol#625-627)
HMCDividendTracker.canAutoClaim(uint256) (contracts/HMC.sol#649-655) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (contracts/HMC.sol#650)
- block.timestamp.sub(lastClaimTime) >= claimWait (contracts/HMC.sol#654)

Average 30d PancakeSwap liquidity is less than $100. Token is either dead or inactive.


Average 30d PancakeSwap volume is less than $100. Token is either dead or inactive.


Average 30d number of PancakeSwap swaps is less than 1. Token is either dead or inactive.


Average PancakeSwap trading volume, liqudity, number of swaps are extremely low. Token seems to be dead.


Swap operations require suspiciously high gas. Contract logic is complex and may disguise some form of scam.


Token is deployed only at one blockchain

Contract has 10% buy tax and 10% sell tax.
Taxes are low but contract ownership is not renounced. Token has a high risk of becoming a honeypot.
