Booster Network

Introducing the fastest way to submit and land Transactions on Base chain. Route tx to closest region and relay to sequencer by propagating through private link. This is the fastest, most reliable way to submit transactions.

• Flashblocks-aware submission: Aligns with Base’s ~200 ms Flashblocks cadence for faster preconfirmation landing.

• BDN reliability: Transactions delivered via bloXroute’s Blockchain Distribution Network (BDN) with redundancy & optimal routing.

• One global endpoint: No need to pick regions, we auto-route your transactions to optimize for speed.

The endpoint returns the transaction hash upon submission. Purchase the Base Speed Boost add-on to access this service.
