TSST.Dog - Smart Contract Audit Report

Summary

TSST.Dog ($TSST) is a new community-driven DeFi token.

We reviewed the TSST.Dog token contract at commit 32ea3c0d2345f0b96849d56f6981337a5aa04467 on the team's Github repository.

Notes on the Contract:
The total supply of the token is set to 900 million $TSST [900,000,000].
No burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
The owner can mint any amount of tokens to any address at any time.
There was no token allocation for our team to analyze as the contract has yet to be deployed to the mainnet.

There is a 10% tax fee on transfers when the user is buying or selling tokens via Uniswap. This fee does not apply to users who are excluded from transfer fees.
The tokens collected from the tax fee are stored in the contract address balance. Once a threshold value of tokens (determined by the operator) is met, the tokens are swapped for ETH and split between four wallets controlled by the team.
The token is designed to be a governance token where 1 token = 1 vote.
Token holders can delegate their voting rights to any address. To save gas, users can also do so using an EIP-712 signature.
The contract utilizes Safemath libraries and complies with the ERC20 token standard.

Ownership/Operator Controls:
The contract utilizes an Operator role. The Operator address has access to specific functionality of the contract.
The Operator can exclude and include accounts from the tax fee.
The Operator can update the threshold number of tokens need to perform a swap to any value at any time.
The Operator can update the percentages of ETH distributed to the four team wallets.
The Operator can update the addresses of the four team wallets at any time.
The Operator can update the Uniswap Router address at any time.
Audit Findings Summary
No external threats were identified.
Please ensure trust in the team prior to investing as they have substantial control in the ecosystem.
