Security Assessments
Summary and Final Words
No crucial issues found
The contract does not contain issues of high or medium criticality. This means that no known vulnerabilities were found in the source code.
Contract owner can mint
It is possible to mint new tokens.
Contract owner can blacklist addresses
It is possible to lock user funds by blacklisting addresses.
Contract owner cannot set high fees
The fees, if applicable, can be a maximum of 25% or lower. The contract can therefore not be locked. Please take a look in the comment section for more details.
Token transfer can be locked
Owner can lock user funds with owner functions.
Token cannot be burned
There is no burning within the contract without any allowances
Ownership is not renounced
The owner retains significant control, which could potentially be used to modify key contract parameters.
Contract is not upgradeable
The contract does not use proxy patterns or other mechanisms to allow future upgrades. Its behavior is locked in its current state.
Scope of Work
This audit encompasses the evaluation of the files listed below, each verified with a SHA-1 Hash. The team referenced above has provided the necessary files for assessment.
The auditing process consists of the following systematic steps:
- Specification Review: Analyze the provided specifications, source code, and instructions to fully understand the smart contract's size, scope, and functionality.
- Manual Code Examination: Conduct a thorough line-by-line review of the source code to identify potential vulnerabilities and areas for improvement.
- Specification Alignment: Ensure that the code accurately implements the provided specifications and intended functionalities.
- Test Coverage Assessment: Evaluate the extent and effectiveness of test cases in covering the codebase, identifying any gaps in testing.
- Symbolic Execution: Analyze the smart contract to determine how various inputs affect execution paths, identifying potential edge cases and vulnerabilities.
- Best Practices Evaluation: Assess the smart contracts against established industry and academic best practices to enhance efficiency, maintainability, and security.
- Actionable Recommendations: Provide detailed, specific, and actionable steps to secure and optimize the smart contracts.
A file with a different Hash has been intentionally or otherwise modified after the security review. A different Hash may indicate a changed condition or potential vulnerability that was not within the scope of this review.
Final Words
The following provides a concise summary of the audit report, accompanied by insightful comments from the auditor. This overview captures the key findings and observations, offering valuable context and clarity.
Ownership Privileges
- The owner can mint an unlimited amount of tokens after the initial deployment.
- The owner can blacklist wallets from transferring of tokens.
- The owner can remove wallets from the blacklist list.
- The owner can pause/unpause the token transfer.
Note - This Audit report consists of a security analysis of the USDI smart contract. This analysis did not include functional testing (or unit testing) of the contract’s logic. Moreover, we only audited one token contract for the USDI team. Other contracts associated with the project were not audited by our team. We recommend investors do their own research before investing.

Findings and Audit result
medium Issues | 3 findings
Pending
#1 medium Issue
The owner can mint unlimited tokens.
The contract allows the owner to mint an unlimited number of tokens after deployment, which is highly discouraged as it can alter the token supply and manipulate its price. To maintain stability and protect the token’s economic integrity, a maximum threshold should be implemented to cap the total mintable amount. This ensures the token supply remains predictable and prevents unchecked inflation or price manipulation.
Pending
#2 medium Issue
The owner can blacklist wallets.
The blacklist function poses centralized risks, as the owner can arbitrarily restrict accounts, leading to potential abuse, loss of trust, and lack of transparency. To mitigate this, implement decentralized governance, requiring community or multisig wallet approval for blacklisting. Define clear, immutable criteria for blacklisting and enable auditing of actions. Include an emergency revert mechanism or appeal process for fairness. Emit detailed events for every blacklist action to ensure transparency. Additionally, rate limits can prevent mass abuse. These measures decentralize control, enhance accountability, and maintain user trust while ensuring the blacklist functionality serves its intended purpose.
Pending
#3 medium Issue
The owner can lock token transfer.
The pause function allows the owner to halt token transfers, posing risks of abuse, loss of trust, and ecosystem disruption if misused or if the owner account is compromised. To mitigate these risks, Clearly define and document conditions for pausing, ensuring it’s used only in emergencies like security breaches. Introduce time limits to prevent indefinite pauses and emit detailed events for transparency. These measures enhance accountability, safeguard user trust, and ensure the pause functionality serves its intended purpose without compromising the token's reliability or utility.
