Girrona Info
Girrona is a new Turing-complete smart-contracting platform, backed by a Proof-of-Stake (PoS) consensus algorithm and WebAssembly (Wasm). The network is a permisionless, decentralized, public blockchain.

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 cannot mint
It is not possible to mint new tokens.
Contract owner cannot blacklist addresses.
It is not 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.
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 exclude/include wallets in fees.
- The owner can update the buy and sell fees of not more than 20%.
- The owner can update the wallet owner's address.
- The owner can enable/disable swapping.
- The owner can update the minimum swap threshold amount.
- The owner can enable/disable wallet-to-wallet transfers without fees.
- The owner can update any arbitrary amount in the max transactions and max wallet amount.
- The owner can claim stuck tokens.
- The owner can update the router address in the contract.
Note - This Audit report consists of a security analysis of the Girrona 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 Girrona 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 | 1 findings
Pending
#1 medium Issue
The owner can lock tokens
The owner can set any arbitrary amount, such as the max transactions and max wallet amount, which is not recommended as this can lock the token transfer for the user if the value is set to zero. There must be a certain check that the value should not get less than at least 0.1% of the total supply of tokens. Also, the owner can set any arbitrary address as the router address, which is not recommended as this can also lock the buying and selling of tokens. There must be a check so that any address cannot be set as the router address in the contract.
low Issues | 4 findings
Pending
#1 low Issue
Local variables shadowing (shadowing-local)
Rename the local variables that shadow another component.
Pending
#2 low Issue
Missing Events Arithmetic (events-maths)
Emit an event for critical parameter changes.
Pending
#3 low Issue
Missing Zero Address Validation (missing-zero-check)
Check that the address is not zero.
Pending
#4 low Issue
Floating pragma solidity version.
Adding the constant version of solidity is recommended, as this prevents the unintentional deployment of a contract with an outdated compiler that contains unresolved bugs.
optimization Issues | 2 findings
Pending
#1 optimization Issue
State variables that could be declared constant (constable-states)
Add the `constant` attributes to state variables that never change.
Pending
#2 optimization Issue
Public function that could be declared external (external-function)
Use the `external` attribute for functions never called from the contract.
informational Issues | 2 findings
Pending
#1 informational Issue
Functions that are not used (dead-code)
Remove unused functions.
Pending
#2 informational Issue
Unused state variables (unused-state)
Remove unused state variables.
