TINKU - Audit Report

Summary

TINKU Audit Report TINKU is a new DeFi project that automatically provides rewards to users who hold the token via frictionless fee redistribution.

TINKU is deployed at 0x47FA4B26c1c52Bc35654F98D10Cd61b9f3E10267 on the Ethereum Mainnet.


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.
