Features

The purpose of the relayer is to create a TPU for receiving transactions and direct that stream to both block builders and validators (with a small delay).

TPU Proxy

• Supports UDP and QUIC for receiving transactions

• Runs filtering and signature verification on packets.

• Sends transactions over grpc to Validator with configurable delay.

Block Engine Forwarding

• Forwards packets to third party block engines (over grpc) to share with searchers.

• Filters based on accounts or programs provided by the block engine.

  • Works with TX v2.

Redundancy & Health Monitoring

• The proxy supports multiple RPC servers for keeping track of cluster time (current slot)

• If the relayer determines it's unhealthy, it force disconnects all validators and prevents future connections until healthy.
