Description

If the swap operation in _swapUnderlyingToAsset fails (e.g., due to insufficient liquidity or router issues), the contract does not have a fallback mechanism to handle such failures gracefully.

Impact

• Transaction Reversions: Swap failures lead to transaction reverts, consuming gas and potentially delaying strategy operations.

• Operational Delays: Continued failures can prevent the strategy from executing its intended function, affecting performance.

Recommendation

• Implement Error Handling for Swaps: Use try-catch blocks to handle exceptions during swaps and implement fallback logic.

  try IVeloRouter(router).swapExactTokensForTokens(

  _amount,

  minOut,

  _path,

  address(this),

  block.timestamp

  ) {

  // Swap succeeded

  } catch {

  // Handle swap failure

  emit SwapFailed(_amount, minOut, _path);

  // Implement fallback mechanism, e.g., alternative swap, hold tokens, alert keeper

  }
