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.
Contract cannot be locked
Owner cannot lock any user funds.
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.
Explorer
This project utilizes a dedicated blockchain explorer. The deployed smart contract is publicly accessible at the following address:
https://scan.trustbitcoin.io/transaction-address/0xC30E0C6def1E76dB3984a4c282a687c4Fe482BEe?type=contract
Ownership Privileges
- The owner can mint unlimited tokens.
- The owner can set the blacklist address.
- The owner can burn blacklisted funds.
Note: Team Trust Bitcoin provided the contract file for this project. Afterward, they launched their own blockchain, TrustBitcoin. Any changes made after the audit are considered outside the scope of the audit, and the audit team holds no responsibility for those changes.

Findings and Audit result

#1 medium Issue
Unlimited Token Minting by Contract Owner
The TBC20Basic contract contains a mint function that is restricted to the owner. This function allows the owner to create an arbitrary number of new tokens at any time, adding them to their own balance and increasing the circulatingSupply. There is no upper limit or maximum cap on the total supply of the token. This mechanism introduces a significant centralization risk, as a malicious or compromised owner could mint a massive number of tokens, thereby inflating the supply and devaluing the holdings of all other users.
Pending
#2 medium Issue
Owner's Ability to Freeze and Burn User Funds.
The contract gives the owner unilateral power to blacklist any address through the setBlacklist function. Once an address is blacklisted, it is restricted from participating in token transfers. More critically, the owner can then invoke the burnBlacklistedFunds function to permanently destroy all tokens held by the blacklisted address. This functionality represents a severe centralization risk, granting the owner the ability to censor transactions and confiscate user assets without any external oversight or due process.
