QAN-01C: Inexistent Event Emission

Type	Severity	Location
Language Specific		QANX.sol:L72-L75

Description:

The linked function adjusts a sensitive contract variable yet does not emit an event for it.

Example:

Copy
72function setChequeSigner(address _newChequeSigner) external {
73    require(msg.sender == chequeSigner && _newChequeSigner != address(0), "Invalid cheque signer");
74    chequeSigner = _newChequeSigner;
75}

Recommendation:

We advise an event to be declared and correspondingly emitted to ensure off-chain processes can properly react to this system adjustment.

Alleviation:

A ChequeSignerUpdated event was introduced to the codebase and is now properly emitted in the setChequeSigner function, alleviating this exhibit in full.
