Real-time Status Updates

Real-time insights into whether or not a transaction has been accepted or not by each private RPC endpoint, and includes any error messages it may have received.

For accepted transactions, users will be updated on their transaction status along the way, be it pending, confirmed, rejected, or failed.

Fast, Reliable Execution

Transaction Boost is an RPC aggregator giving the ability to send private transactions to a multitude of protect RPC endpoints and builders. 

This guarantees faster, more reliable execution than sending to a single MEV protection RPC endpoint alone.
