 The `mev_sendBetaBundle` method is designed to accommodate the specific needs of MEV strategies that do not require transactions to be executed in a priority order within a block. By allowing transactions to be bundled and specifying the block in which they should be included, this method provides a more flexible and efficient way to manage MEV-related transactions. The decision to drop transactions exceeding the block's gas limit in the order they are listed allows for partial fulfillment of the bundle, ensuring that the most critical transactions can be prioritized by the sender.
 
 ## Security Considerations
+
 - This method requires careful management of the block's gas limit to prevent denial of service attacks by submitting large bundles that could monopolize block space.
 - Implementers should ensure that only authorized users have the ability to submit transaction bundles to prevent spam and potential manipulation of block contents.
