Smart Contract Audit Report
FarmX is a new ERC-20 token on Polygon.
For this audit, we reviewed the project team's FarmXToken implementation contract at 0xac6e9bd448ff7542ab566515979cbd1f63db50c8 on the Polygon Mainnet.
No findings were identified, though some centralized aspects are present.
Date: August 26th, 2022.
Updated: September 9th, 2022 to reflect the project's newly deployed Mainnet address.
- The total supply of the token is set to 100 million $FARMX [100,000,000].
- Upon initialization, 100% of the total supply will be split amongst 10 addresses set by the team. The breakdown is as follows:
- 6% of the total supply is minted to the Seed Round fund.
- 9% of the total supply is minted to the Private Round fund.
- 2% of the total supply is minted to the Strategic Round fund.
- 2% of the total supply is minted to the Public Sale fund.
- 1% of the total supply is minted to the DEX Liquidity fund.
- 15% of the total supply is minted to the Team fund.
- 7% of the total supply is minted to the Advisors fund.
- 10% of the total supply is minted to the Staking Rewards fund.
- 15% of the total supply is minted to the Marketing fund.
- 33% of the total supply is minted to the Usage Rewards fund.
- No mint functions are accessible beyond initialization.
- Any user can burn their own tokens to reduce the total supply.
- Any user can burn tokens on another user's behalf if an allowance has been granted.
- The $FARMX token represents votes intended to be used in a DAO where one token represents one vote.
- Users may delegate their votes to another address allowing them to vote on behalf of the user.
- Once votes are delegated, the user must explicitly delegate back to themselves to regain their votes.
- Users also have the option to delegate through the use of a signed message, allowing for a gasless delegation for the user.
- There are no fees associated with transferring tokens.
- The team can upgrade the contract at any time.
- As the contract is implemented with Solidity v0.8.x, it is safe from any possible overflows/underflows.
- The contract complies with the ERC-20 token standard.

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.
