BlockGo

Appearance

BlockGo Transaction Gateway ​

BlockGo is a Solana transaction relay designed for ultra-low latency submission.

Endpoints ​

RegionEndpoint
Amsterdamhttp://ams1.blockgo.trade/?api-key=YOUR_API_KEY
http://ams2.blockgo.trade/?api-key=YOUR_API_KEY
Frankfurthttp://fra1.blockgo.trade/?api-key=YOUR_API_KEY
New Yorkhttp://ny1.blockgo.trade/?api-key=YOUR_API_KEY

INFO

The quota for each endpoint is an independent 5 RPS. We recommend sending requests to at least all endpoints in the lowest-latency region. For example, if your server is in AMS, send requests to both ams1 and ams2. If you’re looking for the ultimate performance, send requests to all endpoints at the same time.

TIP

Contact us to obtain an API key. Default quota: 5 RPS per endpoint.

Examples ​

cURL ​

bash
curl -X POST 'http://fra1.blockgo.trade/?api-key=YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "sendTransaction",
    "params": ["YOUR_BASE64_TX", {"encoding": "base64"}]
  }'

Rust ​

rust
use solana_client::rpc_client::RpcClient;
use solana_sdk::transaction::VersionedTransaction;

fn send_transaction(tx: &VersionedTransaction, api_key: &str) -> Result<String, Box<dyn std::error::Error>> {
    let endpoint = format!("http://fra1.blockgo.trade/?api-key={}", api_key);
    let client = RpcClient::new(endpoint);
    let sig = client.send_transaction(tx)?;
    Ok(sig.to_string())
}

TypeScript ​

typescript
import { Connection } from '@solana/web3.js';

async function sendTransaction(
  transaction: VersionedTransaction,
  apiKey: string
): Promise<string> {
  const endpoint = `http://fra1.blockgo.trade/?api-key=${apiKey}`;
  const connection = new Connection(endpoint);
  const signature = await connection.sendTransaction(transaction);
  return signature;
}

Go ​

go
// Use any JSON-RPC client to call sendTransaction.
// Key: set endpoint to http://<region>.blockgo.trade/?api-key=...

Tip address ​

Each transaction must include a System Program transfer instruction sending a tip to the BlockGo tip address, with a minimum tip of 0.001 SOL. To avoid conflicts and optimize performance, it is recommended to randomly select a tip address for each transaction.

Keepalive ​

bash
curl -sS -X POST 'http://fra1.blockgo.trade/?api-key=YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"getHealth"}'
# Response: {"jsonrpc":"2.0","result":"ok","id":1}

INFO

Call JSON-RPC getHealth every 60 seconds to keep the connection warm and reduce tail latency.
