STRATA TODAY - Smart Contract Audit Report

Summary

STRATA TODAY ($STRATA) is a new community-driven DeFi token that performs automatic liquidity-adds and pays out static rewards to holders.

We reviewed the STRATA TODAY Token contract at 0x5bE6eC9a5d1EF8390d22342EDA90E2Fc6F1A9f7d on the Binance Smartchain mainnet.

Notes on the Contract:
The total supply of the token is set to 22 million $STRATA [22,000,000].
No minting or burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
At the time of writing this report, 100% of the total supply belongs to the owner as the project was recently deployed.

There is a 1% tax fee, 1% liquidity fee, and a 2% dev fee on all transactions for any "non-excluded" address that participates in a transfer.
Users who hold tokens will automatically benefit from the frictionless fee redistribution at the time of each transaction as the tokens collected through the tax fee are removed from the circulating supply.
The tokens collected from the liquidity fee during transfers are stored in the contract address balance. Once the threshold value of 4.4 million tokens is met, a swap will occur for the purpose of funding Uniswap liquidity.
Liquidity-adds are funded by selling a portion of the tokens collected as fees (after the threshold number of tokens is met), then pairing the received ETH with the token, and adding it as liquidity to the ETH pair.
The recipient of the newly created LP tokens is the owner. We recommend that the team locks these newly acquired LP tokens.
The tokens collected from the dev fee are sent to the team's dev wallet.
As the contract is implemented with Solidity v0.8.x, it is protected from overflows.

Ownership Controls:
The owner can enable/disable transfer fees at any time.
The owner can exclude and include accounts from transfer fees at any time.
The owner can enable/disable automatic liquidity adds at any time.
The owner can update the Uniswap Router address at any time.
Audit Findings Summary
No external threats were identified.
