Migration Guide

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

From Jito ShredStream​

Blockspace ShredStream runs on UDP raw delivery rather than gRPC. Your shred decoder doesn't need to change — only how the packets get to you.

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

After (Blockspace UDP): pick a destination IP and UDP port for each region (FRA, AMS, TYO, NY, LON, DUB, SGP), then hand them to the dashboard. Allowlist Blockspace's proxy IPs in your firewall. After that, packets just arrive — each UDP datagram is one raw Solana shred.

For a receiver, jito-labs/shredstream-proxy is the recommended starting point, and your existing shred-decoding logic carries over unchanged. Only the wire transport is different.

See the full ShredStream Quickstart for the complete setup.

From other SWQOS providers​

Nothing exotic here: SWQOS endpoints follow the standard Solana RPC sendTransaction shape, so it's a matter of swapping the endpoint URL and getting your signing pubkey whitelisted in the dashboard. Full setup is in the SWQOS Quickstart.

From another TPU relay / mempool provider​

Relayer/TPU is built on gRPC streams scoped to your subscribed validators. Connection details and filter configuration live in the Relayer/TPU Quickstart.
