Higher score is always better


This smart contract has been reviewed by George Stamp and found no backdoor code, and the owners privilege is to start the dapp. There is no malicious code that allows the owner (or other) to withdraw all funds from the smart contract.

This is a fork of TRXCHAIN, but we do not have the original smart contract to show the differences.

Contract Details

Chain: BNB Smart Chain.
Coin: BNB
Dapp Type: ROI
Daily ROI: 1.5%
Referral reward: 10% + 20% to 5% depending on the number of referred wallets.
First deposit: min 0.01 BNB, max 20.00 BNB.
Can deposit again if investor has ROI 3 times (3x ROI is one cycle):
- the new deposit must be greater than the first deposit & smaller than the new cycle’s maximum (20, 40, 80, 200 BNB),
- each new cycle resets ROI so the investor may ROI 3 times again and may invest more,
- deposits require a referral, which is provided by the application using this contract.

Referrals are set only once in the lifetime of an investment.

Every day a random pool of reward is awarded to the top 4 referrers of the day, and to get on top of that pool it is necessary to get more referral rewards than the top of the pool.
The top 4 receives rewards from 40% to 10% bonus on top of the 1% total pool.


There are no backdoor methods that withdraw funds to a non investor wallet.

Owner Privileges

updateStarttime - changes the start time of the contract, when deposits are then possible. The owner can change the startTime to prevent deposits, however that is not beneficial to himself and so does not impact the score.


Withdraw fee: 0% (not modifiable by owner)
Deposit fee: 10% (not modifiable by owner)


The contract is fairly complex and has a specific coding style.

The original developer made proper use of the Pull-over-Push and check-effect-interaction patterns which points at a skilled developer.

Team Trust

The team is known and has a large community, but has no previous projects.

Other Risk

This is a yield farm application that relies on new funds. If the contract hits $0, the investors will not be paid out. However, the daily ROI and referral rewards are reasonable.


This contract has been audited by a human.
