The cancelParticipation function does not emit an event.

Description

• The cancelParticipation function does not emit an event after state changes.

  function cancelParticipation() public {

  if (block.timestamp >= eventStartDate) {

  revert eventStarted();

  }

  ​

  uint256 refundAmount = stakedAsset[msg.sender];

  ​

  stakedAsset[msg.sender] = 0;

  ​

  uint256 shares = balanceOf(msg.sender);

  ​

  _burn(msg.sender, shares);

  ​

  IERC20(asset()).safeTransfer(msg.sender, refundAmount);

  // @audit-low missing event emission

  }// Root cause in the codebase with @> marks to highlight the relevant section

Risk
