This URL uses AWS geo-routing to find the best RPC to send to. We have found this can sometimes route requests to the wrong region, so we have also added specific geo-location URLs. We reccomend you use these.

#### Block Building Algorithm

Our builder runs multiple sorting algorithms concurrently that compete against each other to produce the most valuable block possible.

Sorting of bundles and transactions is not necessarily ranked by effective gas price, and as such top-of-block execution is not guaranteed. Based on how transactions interact with each other and the current state, including transactions with lower effective gas prices before higher paying ones may yield more valuable blocks, which is what our algorithms optimise for.

We will never unbundle a bundle, and will never broadcast any bundles or private transactions to the public mempool.

#### Priority Queues

We often get asked about priority queues. We used to have these but have since removed them as we now get through all bundles without needing one. There is no priority system.
