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.

This is a fork of Kingdom Cash, with a very little difference on crystals & gold prices.

Investors can buy Crystals using BNB (1 Crystal = 0.0004 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 = 0.000004 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.

Owner Privileges

initialize - allows withdrawals once and forever.


Deposit fees: 13% (not modifiable by owner):
- 5% as ether,
- 8% as crystal.

The owner is the default referral and receives additional fee as a crystal that generates more yield. Since this contract is not compliant with the latest George Stamp requirements to remove one of the two advantages, this score goes to zero.


This is a simple fork of Kingdom Cash.

Team Trust

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.
