ACTs Token

Smart Contract Audit Report

Audit Summary

ACTs Token is a new BEP-20 token that features automatic liquidity adds and pays holders dividends in BUSD.

For this audit, we reviewed the project team's ActsToken contract at 0xD8d07788facC1CA19De4646Ac78d8c74baBd3108 on the Binance Smart Chain Mainnet.

Audit Findings

Informational findings were identified and the team may want to review them. In addition, centralized aspects are present.
Date: August 5th, 2022.

Finding #1 - ActsToken- Informational

Description: Several state variables can never be modified, but are not declared constant.

BUSD, DEAD, DEAD_NON_CHECKSUM, ZERO, _totalSupply

Recommendation: These state variables should be declared constant for additional gas savings on each reference.

---

Finding #2 - ActsToken- Informational

Description: Although the SafeMath library is utilized, the contract is deployed with Solidity v0.8.7 which has built-in overflow checks.
Recommendation: SafeMath could be safely removed to reduce contract size, deployment costs, and gas costs on all transactions that utilize it.

Contracts Overview

• The total supply of the token is set to 1 quadrillion $ACTS [1,000,000,000,000,000].
• No mint 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.


• The contract enforces a maximum transaction amount (determined by the owner) which imposes a limit to the number of tokens that can be transferred during any given transaction.
• The contract features an Antisniper mechanism that is triggered when a user attempts to transfer tokens within 1 block of the contract launch time. The account initiating the transfer will be taxed at a ~99% rate.
• There is a Reflection fee, Liquidity Fee, Proceeds Fee, and Buyback fee, on all transfers where neither the sender nor the recipient is excluded from fees.
• Fees are increased to 100% on all sell transactions that take place within the first 24 hours of the contract launch time.
• Fees can also be increased during a sell via PancakeSwap up to a value proportional to the time left in the buyback multiplier period.
• The tokens collected from fees are stored in the contract address. The tokens are swapped for BNB for the purpose of funding Pancakeswap liquidity when the following conditions are met:
  • The automatic liquidity add functionality is enabled by the team.
  • The threshold number of tokens (determined by the owner) in the contract address has been reached.
  • The contract is not currently performing an automatic liquidity add or a buyback.
  • The caller is not initiating a buy transaction via Pancakeswap.
• Liquidity-adds are automatically performed by selling the tokens collected as fees, pairing the received BNB with the token, and adding it as liquidity to the BNB pair.
• The LP tokens received through this process are sent to the Liquidity address set by the team. We recommend that the team lock these newly acquired LP tokens.
• When the automatic liquify functionality is disabled by the team, the BNB collected through the Liquidity fee is sent to the Liquidity address set by the team.
• The tokens collected from the Proceeds Fee and Buyback fee are swapped for BNB and sent to the team's Proceeds wallet and Buyback wallet respectively.
• The tokens collected from the Reflection Fee are swapped for BNB and sent to the DividendDistributor contract where they are swapped for BUSD and distributed as rewards.
• An automatic buyback will be triggered on token transfers when the following conditions are met:
  • The automatic buyback functionality is enabled by the team.
  • The threshold amount of BNB in the contract address has been reached.
  • The contract is not currently performing an automatic liquidity add or a buyback.
  • The caller is not initiating a buy transaction via Pancakeswap.
  • The cool-down number of blocks (determined by the owner) since the previous buyback has passed.
• An automatic buyback is performed by swapping an amount of BNB (determined by the owner) in the contract for $ACTS and sending it to the 0x..dead address.
• Automatic buybacks will be disabled when the total amount of BNB used for buybacks reaches the buyback cap (set by the team).
• The contract utilizes the SafeMath library to prevent overflows/underflows.
• The contract complies with the BEP-20 token standard.


• Any user that holds any number of $ACTS tokens is eligible to claim dividends once the amount of dividends they are due reaches a minimum threshold value determined by the team.
• Once dividends are distributed, they will need to be claimed; claiming happens automatically on each transfer.
• Dividend rewards can also be claimed manually by kicking off the claim cycle, which will process all eligible token holders.
• Alternatively, a user can manually claim dividends as an individual.
• There is a wait time (set by the team) between claiming dividend rewards.
• Claimed dividends are sent to the user's wallet address.

Ownership Controls:

• The owner can assign addresses to an Authorized role which can be used to maintain control over various role-restricted functions within the contract.
• Authorized addresses can set each fee percentage to any values as long as the total fee percentage combined does not exceed 25%.
• Authorized addresses can exclude accounts from transfer fees, dividends, and the maximum transaction amount at any time.
• Authorized addresses can set the maximum transaction amount to any value greater than 1 trillion at any time.
• Authorized addresses can enable/disable the automatic liquify functionality at any time.
• Authorized addresses can update the threshold number of tokens that triggers automatic liquidity adds to any value at any time.
• Authorized addresses can enable/disable the automatic buyback mechanism at any time.
• Authorized addresses can set the automatic buyback cap, BNB threshold value, and block period to any values at any time.
• Authorized addresses can set the last automatic buyback block to the current block.number at any time.
• Authorized addresses can update the minimum threshold of dividends a user must be due in order to claim rewards to any value at any time.
• Authorized addresses can update the wait time between claiming rewards to any value at any time.
• Authorized addresses can manually trigger a buyback at any time.
• Authorized addresses can update the buyback multiplier to any value at any time.
• Authorized addresses can update the Liquidity address, Buyback address, and Proceeds address at any time.
• Authorized addresses can update the maximum amount of gas used for processing to any value up to 750,000 at any time.

What is a SourceHat Audit?

Typically, a smart contract audit is a comprehensive review process designed to discover logical errors, security vulnerabilities, and optimization opportunities within code. A SourceHat Audit takes this a step further by verifying economic logic to ensure the stability of smart contracts and highlighting privileged functionality to create a report that is easy to understand for developers and community members alike.

How Do I Interpret the Findings?

Each of our Findings will be labeled with a Severity level. We always recommend the team resolve High, Medium, and Low severity findings prior to deploying the code to the mainnet. Here is a breakdown on what each Severity level means for the project:

• High severity indicates that the issue puts a large number of users' funds at risk and has a high probability of exploitation, or the smart contract contains serious logical issues which can prevent the code from operating as intended.
• Medium severity issues are those which place at least some users' funds at risk and has a medium to high probability of exploitation.
• Low severity issues have a relatively minor risk association; these issues have a low probability of occurring or may have a minimal impact.
• Informational issues pose no immediate risk, but inform the project team of opportunities for gas optimizations and following smart contract security best practices.
