TxBoost is a platform that facilitates the submission of MEV (Miner Extractable Value) bundles to mining pools through a cloud-based API. By forwarding user-submitted bundles to mining pools, TxBoost aims to ensure faster submission and higher success rates for transactions. The service provides an RPC endpoint with authentication for secure interactions and offers various plans to accommodate different levels of usage, including a free tier with specific limits on bundle submissions and simulations.
