Migration Guide

Moving from another MEV provider to Blockspace is mostly a transport / endpoint swap.

From Jito ShredStream​

Blockspace ShredStream uses UDP raw delivery, not gRPC. The migration is mostly a transport change — you keep your shred decoder, switch how packets arrive.

Before (Jito gRPC): subscribe to a gRPC stream of shred messages.

After (Blockspace UDP):

  1. Pick a destination IP and UDP port for each region (FRA, AMS, TYO, NYC, LDN, DUB).
  2. Provide them in the dashboard.
  3. Allowlist Blockspace proxy IPs in your firewall.
  4. Receive packets — each UDP datagram is one raw Solana shred.

Recommended receiver: jito-labs/shredstream-proxy. Your existing shred decoding logic works unchanged; only the wire transport differs.

See the full ShredStream Quickstart for the complete setup.

From other SWQOS providers​

SWQOS endpoints follow the standard Solana RPC sendTransaction shape. Swap the endpoint URL and ensure your signing pubkey is whitelisted in the dashboard. The SWQOS Quickstart covers the full setup.

From another TPU relay / mempool provider​

Blockspace Relayer/TPU and Relayer/TPU use gRPC streams scoped to subscribed validators. See the Relayer/TPU Quickstart for connection details and filter configuration.
