Smart Contract Audit Report
Audit Summary
Raini Studios is a new ERC-20 token on Beam.

Audit Findings
No findings were identified.
Date: September 8th, 2023.
Updated: September 15th, 2023 to reflect the contract's Mainnet address.
Contract Overview
- The total supply of the token is set to 1 billion $RST [1,000,000,000].
- No mint or burn functions are publicly accessible, though the circulating supply can be decreased by sending tokens to the 0x..dead address.
- At the time of writing this report, 32.3% of the total supply belongs to the team's unverified scheduled vesting contract. This contract was out of scope for this audit.
- 11.69% of the total supply belongs to the deployer.
- 6% of the total supply belongs to the team's unverified VC vesting contract. This contract was out of scope for this audit.
- There is a Transfer fee charged on all transfers where the recipient has been granted the "Fee-To" role and the sender has not been granted the "No-Fee-From" role.
- The tokens collected through the Transfer fee are sent to the Treasury address set by the owner.
- The Default Admin can set the contract's Transfer fee to any percentage up to 2% at any time.
- The owner can set the Treasury address to any address at any time.
- As the contract is implemented with Solidity v0.8.x, it is protected from 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.
