This smart contract has been reviewed by George Stamp. We did not find any vulnerability nor backdoors that would lead to stolen liquidity or any sort of malicious activity. Kingdom cash forks are now requested to remove unused referrals going to the owner OR remove default additional fee as crystal to the owner. This contract complies.

This is a fork of Kingdom Cash with a little difference on how referral rewards are handled: goes 3 upline referrals.

Investors can buy Crystals using BNB (1 Crystal = 0.0005 BNB). These Crystals can be used to unlock/buy tower floors and to add more warriors to each floor. The higher the tower and the more warriors hired the more daily profit will be received. There are a total of 5 towers, and each tower comes with 1 warrior and can be upgraded to a maximum of 5 warriors per floor. The warriors produce Gold, which can be sold (1 Gold = 0.000005 BNB).

An investor can sell their tower, which will set warriors count to zero (and hence no daily profit), and this will send the user the calculated profit for the next 5 days.

Team Trust

The team is known and has built two other kingdom cash forks. They also seem to share the same contract address, they are just on different blockchains (AVAX & MATIC).

Other Risk

This is a yield farm that relies on funds invested to payout existing users. If the contract reaches $0 then investors will not be paid out anymore.

There are many kingdom cash / pizza tower forks out there, we recommend users to do their own research as they should always do.
