Netcoincapital Token - Smart Contract Audit Report
Summary
Netcoincapital intends to build decentralized platform for their native $NCC Token and to support additional cryptocurrencies.
For this audit we reviewed the project's token contract by using a Solidity file that was provided to us by the team.
Notes of the contract:
- The total supply of the token is set to be 102 million $NCC [102,000,000].
- No minting functions are accessible beyond deployment.
- Holders may use the burn function to remove tokens from their own balance and automatically reduce the total supply.
- Holders that have the approval to do so may burn tokens from another holder's wallet to reduce the total supply.
- Holders that have the approval to do so may transfer tokens from another holder's wallet to any recipient.
- The contract includes a fallback function to revert all inbound transfers of TRON in the event that TRON is accidentally sent to the contract.
- Ownership of the contract can be transferred, but must be accepted/approved by the new owner in order for this ownership transfer to take place.
- The owner has the ability to recover any TRC20 tokens that were erroneously sent to the contract address.
- No additional ownership-restricted functions are present in the code.
- The contract does not utilize SafeMath, however the functions contain logic that prevents overflow/underflow issues.
Audit Findings Summary
- No issues from external attackers were identified.
