Yellowstone gRPC

Geyser-based streaming over gRPC. Faster and more efficient than polling JSON-RPC or subscribing via WebSocket - you get account updates, transactions, slots, and full blocks pushed to your client as they happen.

Endpoint

http://cute-rabbit.by.supanode.xyz:10000/

No TLS on the shared tier. No auth token - access is controlled by IP allowlist, same as HTTP and WebSocket.

gRPC is available on paid shared tiers only. You need Build ($179/mo) or higher.

Example (Rust)

Using yellowstone-grpc-client:

use yellowstone_grpc_client::GeyserGrpcClient;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let mut client = GeyserGrpcClient::connect(
        "http://cute-rabbit.by.supanode.xyz:10000/",
        None, // no x-token, IP allowlist handles auth
        None,
    ).await?;

    println!("Connected to HighTower gRPC");

    // Set up your subscription filters here
    // See: https://github.com/rpcpool/yellowstone-grpc

    Ok(())
}

What You Can Stream

• Account updates - replicate account state as it changes on-chain
• Transactions - filter by program, account, or signature and get them as they are processed
• Slots - new slot notifications
• Blocks - full block data including all transactions

Filtering is important. An unfiltered subscription on a shared tier will generate a massive data stream and likely get throttled. Always specify account or program filters.
