Introduction

HighTower provides Solana blockchain infrastructure — RPC endpoints, WebSocket feeds, and Yellowstone gRPC streaming. The service is built for developers and traders who need low latency and don't want to run their own nodes.

What's Available

  • HTTP JSON-RPC — standard Solana RPC for reading state and submitting transactions
  • WebSocket — real-time slot/account/log subscriptions
  • Yellowstone gRPC — Geyser-based data streaming (accounts, transactions, blocks)

All endpoints are hosted in Frankfurt (FRA) by default. Other regions can be arranged for dedicated deployments.

Access Model

There's no dashboard or self-serve signup. Access is provisioned manually:

  1. Open a ticket in Discord (#service-ticket channel)
  2. Tell us your use case, which interfaces you need (HTTP/WS, gRPC, or both), and your IP address(es)
  3. We set up the endpoint and allowlist your IPs
  4. You get the connection URL — typically within several minutes to a couple of hours.

No API keys, no tokens. Authentication is IP-based.

To get started, see Access & Authentication.
