For Searchers

You extract MEV from the Solana validator network — JIT, atomic arb, liquidations, expirations. That puts you closer to the metal than bots: pre-leader transaction visibility and precise submission timing to the highest-priority lanes are what matter here.

Use of Relayer/TPU is governed by the Blockspace acceptable-use terms. Front-running and sandwiching of user transactions are prohibited, and the network applies filtering intended to prevent that activity.

What you'll use​

Relayer/TPU

MEV mempool plus direct TPU submission. Stream pre-leader transactions to a gRPC Block Engine you operate; ship winning bundles direct to the validator TPU in the ~157ms priority window. Pay-on-performance.

~157ms TPU window · pay-on-performance

Relayer/TPU is the searcher-side counterpart to the validator product Searcher Connection — validators publish their TPU traffic; you consume it and submit bundles back through the TPU adapter.

How it works end-to-end​

Relayer  →  detect pending tx  →  build response bundle
                                              │
                                              ▼
                                    TPU adapter → land in the next leader slot

The Relayer half streams incoming transactions before they're sequenced; you identify arb opportunities or signals, then the TPU-adapter half ships your response bundle directly to the validator's TPU in the ~157ms window. You only pay upon successful execution.

Searcher vs Bot stack​

A pure searcher stack (this page) reads pending transactions and times submissions to specific upcoming leaders. A bot stack (for bots) works one step later, tracking in-flight pool state via post-sequencing shreds. The two are complementary; mature operators often run both.

Pricing​

Pay-on-performance on the TPU adapter; the Relayer half is application-based. Live terms in the dashboard or via support-blockspace@everstake.com.

Get started​

  1. Apply via support-blockspace@everstake.com or in the dashboard.
  2. Read the Relayer/TPU quickstart — gRPC Block Engine receive + TPU-direct bundle submit, both covered.
  3. Pair with SWQOS or ShredStream if your strategy needs them too.

Acceptable use​

Use of Relayer/TPU is governed by the Blockspace acceptable-use terms. You may not engage in, facilitate, or support the deliberate front-running or back-running of target transactions (sandwich attacks), or any other Maximal Extractable Value strategy that constitutes market abuse, fraud, or manipulation under applicable law. Blockspace applies filtering intended to prevent prohibited activity, and access may be revoked for violations.
