LowDifferent Solidity VersionsFixed

Multiple Solidity versions are used in the codebase. `^0.8.15` is used on line 1012 just before contract `TokenSwap`, while `^0.8.0` is used in multiple other locations. ```solidity=1012 pragma solidity ^0.8.15; ```

LowFunction Should Be Declared ExternalFixed

The functions which are never called internally within the contract should have external visibility for gas optimization. - Function `swap()`, line 1061: ```solidity=1061 function swap( string memory externalRecipient, string memory toBlockchain, uint256 amount ) public payable virtual { ... ``` - Function `setSwapBlockchain()`, line 1080: ```solidity=1080 function setSwapBlockchain(string memory toBlockchain, bool status) public virtual onlyRole(SETTING_CONTRACT) { ``` - Function `setCommissionPrice()`, line 1085: ```solidity=1085 function setCommissionPrice(string memory toBlockchain, uint256 value) public virtual onlyRole(SETTING_CONTRACT) { ```

LowMissing Emit EventsFixed

The function that affects the status of sensitive variables should be able to emit events as notifications to users. - `setSwapBlockchain()` - `setCommissionPrice()`
