Cap Automaters allow the Supply Cap defined in and the Borrow Cap defined in to be dynamically adjusted.The Cap Automater is defined in terms of three parameters:1. gap - the target available exposure2. ttl - the cooldown period for cap increases3. max - the absolute maximum exposureAny user can permissionlessly update a covered Supply Cap or Borrow Cap so the available exposure is equal to the target, as long as the resulting exposure does not exceed the specified maximum limit and the cooldown period has elapsed in the case of increases to the Supply Cap or Borrow Cap.
