Rocket Network - Smart Contract Audit Report
Summary
Rocket Network ($RNK) is a deflationary token with frictionless fee redistribution on the Binance Smart Chain.
We audited Rocket Network's token contract that is deployed at 0x420Ab4821839D337DBe5e5e0768f64C892eA35D1 on the Binance Smart Chain mainnet.
Notes on the Contract:Audit Findings Summary
- The total supply of the token is currently ~19.9 trillion [19,991,957,487,346].
- No minting or burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
- At the time of writing this report, the top holder is in possession of 21.4% of the total supply.
- 21.03% of the total supply has been sent to the 0x..dead address.
- 18.7% of the total supply belongs to an unverified contract.
- 12.27% of the total supply belongs to the owner.
- The next two holders own a cumulative 20% of the total supply.
- There is a tax fee, burn fee, and a charity fee on all transactions for any "non-excluded" address that participates in a transfer.
- Users who hold tokens will automatically benefit from the frictionless fee redistribution at the time of each transaction as the tokens collected through the tax fee are removed from the circulating supply.
- The tokens collected from the burn fee are burned to reduce the total supply.
- The tokens collected from the charity fee are sent to the team's charity wallet.
- The contract complies with the BEP20 Token standard.
- As the project is implemented with Solidity v0.8.x, it is protected from overflows.
Ownership Controls:- Ownership has not been renounced.
- The owner can modify the tax fee, burn fee, and charity fee to any percentages at any time.
- The owner can exclude and include accounts from transfer fees.
- The owner can update the team's charity wallet to any address at any time.
- No external threats were identified.
- Please ensure trust in the team prior to investing as they have substantial control in the ecosystem and currently own a large portion of the total supply.
