Bundle Submission

Searchers can submit MEV bundles to the Cloud API, where they are validated and forwarded to Builders that are connected to BSC validators participating in Bloxroute’s MEV solution. Bundles are optimized to maximize validator rewards, ensuring efficient MEV extraction.

Purchase the Bundle Size Add-on to send bundles with more than 2 transactions.
