SendInLoop

An optional detector that identifies send functions being called inside loops.

Why is it bad?

Calling send functions inside loops can lead to unintended consequences, such as excessive message sending, increased gas consumption, and potential race conditions. Loops with send calls should be refactored to avoid these issues. This detector helps flag such code, prompting the developer to reconsider the design.

Example

fun exampleWhileLoop(limit: Int, owner: Address) {
  let i = 0;
  while (i < limit) {
      send(SendParameters{ // Highlighted: An auditor should review the loop
          to: owner,
          value: 0,
          bounce: false,
          body: Msg{ a: i }.toCell()
      });
      i += 1;
  }
}
