Sanshu Inu - Smart Contract Audit Report

Summary

Sanshu Inu Audit Report Sanshu Inu is a new token with frictionless fee redistribution.

For this audit, we reviewed the SanshuInu contract on the Ethereum blockchain mainnet at 0xc73c167e7a4ba109e4052f70d5466d0c312a344d.


Notes on the SanshuInu Contract:
  • The total supply of the SANSHU token is initially set to 100 quadrillion.
  • No mint functions exist, but anyone can burn their own tokens at any time by calling the reflect function.
  • At the time of writing this report, 61.5% of the token supply has been sent to the 0x..dead address.
  • 4.5% of the token supply is stored in the Memestake contract.
  • The next 5 largest token holders have 6% of the total supply.
  • 0.89% of the token supply is in Uniswap liquidity.
  • Of that liquidity, 98% of the LP tokens are held in the Memestake contract.

  • There is a 2% tax fee on all transactions; this percentage cannot be changed.
  • Users who hold tokens will automatically benefit from the frictionless fee redistribution at the time of each transaction as the tokens collected through taxes are removed from the circulating supply.
  • There is a maximum transaction amount tokens, but this does not apply to the owner during transactions where the owner is either the sender or the recipient; the owner can set the max transaction amount to any value at any time.
  • The owner can also exclude any address from rewards at any time.
  • The team has worked with us to optimize these contracts for gas efficiency.
  • The contracts utilize the SafeMath library to prevent overflows along with following the ERC20 standard.
Audit Findings Summary
  • No security issues from outside attackers were identified.
  • Ensure trust in the team as they have some control in the ecosystem.
  • Date: July 17th, 2021
  • Updated: November 19th, 2021 to remove the discontinued MemeStake and MFund contracts.
