PsychoDoge Token - Audit Report

Summary

PsychoDoge Audit Report PsychoDoge ($PSYCHODOGE) is a new community-driven DeFi token on the Binance Smart Chain that is an automatic liquidity providing protocol that pays out static rewards to holders.

PsychoDoge Token contract is deployed at 0xD4cdBd31f55c6F06B267809b5eca0f0C257c8A6A on the Binance Smartchain mainnet.

Notes on the Contract:
  • The total supply of the token is initially set to 160 quadrillion $PSYCHODOGE [160,000,000,000,000,000].
  • 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 $PSYCHODOGE token supply is in possession of the owner as the project was recently deployed.

  • There is a 'tax fee', 'liquidity fee', and 'marketing fee' on all transactions for any "non-excluded" address that participates in a transfer. The owner has the ability to modify these fees to any percentage at any time. The tax fee is doubled on sell transactions to the Uniswap pair.
  • The tax fee is redistributed to existing token holders instantly and automatically at the time of each transaction.
  • The liquidity fee charged on transactions is stored in the contract and, once a threshold value is met, is used to fund Pancakeswap liqudity. This functionality can be enabled/disabled by the owner.
  • Liquidity-adds are funded by selling a portion of the tokens collected as fees (after the threshhold as determined by the owner is met), then pairing the received BNB with the token, and adding it as liquidity to the BNB pair.
  • The recipient of the newly created LP tokens is the owner of the contract.
  • The marketing fee that gets collected on each transaction is allocated to the team's marketing wallet. This address is set by the owner and can be changed at any time.
  • The contract features an anti-bot mechanism where addresses will be considered a "sniper" if a transfer is attempted within the first four blocks upon launch. Snipers will be taxed at 98% rate that is applied and sent directly to the marketing wallet.

  • The owner of the contract can exclude and include accounts from transfer fees and reward distribution.
  • The owner has the ability to set and update a maximum transaction percent at any time, which will impose a limit to the number of tokens that can be transferred during any given transaction.
  • This maximum transaction amount does not apply to the owner during transactions where the owner is either the sender or the recipient.
  • The owner has the ability to use the "lock" function in order to temporarily set ownership to address(0). Ownership is restored after the duration of time determined by the owner has passed and they use the 'unlock' function. Ownership can additionally be restored (even if ownership was previously renounced), by using the unlock function a second time.
  • Ownership has not been renounced.
  • The contract utilizes SafeMath libraries along with following the BEP20 standard.
  • As the project is implemented with Solidity v0.8.0, it is protected from overflows.
Audit Findings Summary
  • No external threats were identified.
  • We recommend that the team renounces ownership.
  • Please ensure trust in the team prior to investing as they have substantial control in the ecosystem.
