Solana Yellowstone gRPC
Solana Yellowstone gRPC is live on Tatum. You can keep a single gRPC connection open to Mainnet and receive transactions, accounts, blocks, and slot updates as they happen, instead of hammering JSON-RPC on a timer.
Under the hood it follows the same Geyser-style streaming path many Solana operators already know. If your bot, indexer, or dashboard has been stuck waiting on poll intervals, this is the lane meant for you.

What you get
- Speed: Push-style updates beat round-tripping the same RPC call every few hundred milliseconds.
- Payload: Messages use Protocol Buffers, which tends to be lighter than JSON for this kind of volume.
- Control: Subscribe to the account, slot, block, or transaction shape your product cares about.
