TINKU - Smart Contract Audit Report
Summary
TINKU is a new DeFi project that automatically provides rewards to users who hold the token via frictionless fee redistribution.
Notes on the Contract:
- TINKU's code implements and builds upon the fee-redistribution features pioneered by Reflect Finance.
- The total supply of the token is 100,000,000,000,000,000 TINKU.
- No mint or burn functions exist, and tokens cannot be transferred to the burn address. However, the team sent 49.5% of the total supply to the contract address so the tokens are permanently stuck. This is often used as a deflationary mechanism.
- At the time of writing this report, 49.75% of the tokens are in the token contract address.
- There is a 1% fee that is redistributed to existing token holders instantly and automatically at the time of each transaction. Since the contract address participates as a normal holder, it will increasingly be distributed to the contract address as it continues to surpass 50%.
- 7.77% of the supply is in Uniswap liquidity.
- 98.4% of the current liquidity is set to unlock on September 1st, 2021.
- The next largest wallet (after Uniswap) contains 2.22% of the total TINKU supply.
- There is no maximum number of tokens that can be sent in a transaction.
- Some gas optimizations can be achieved through declaring functions external instead of public and some variables constant. As this contract is already deployed, this is merely informational.
- The team utilizes SafeMath to prevent overflows.
- Ownership has been renounced.
Audit Findings Summary
- No external threats were identified.
- As with any token, please ensure trust in the team prior to investing.
