The Challenge: Inconsistent Transaction Landing

On Solana, transaction landing can become inconsistent because of:
  • Blockchain congestion during peak periods
  • Network latency between clients, relays, and leaders
  • Differences in infrastructure quality
This uncertainty has the biggest impact on power users such as traders, bots, and dApps, where execution quality and consistency are critical.

​
Our Solution: Stake-Enabled, Multi-Path Submission

Stellium uses staked connections and automatically submits transactions to validator leaders through low-latency routes. By optimizing the networking stack end to end, Stellium improves landing rates and reduces transaction finality times.

​
API Usage

Stellium accepts the standard Solana sendTransaction JSON-RPC format: 
curl -X POST 'https://STELLIUM_ENDPOINT/$APIKEY' \
-d '{
    "jsonrpc": "2.0",
    "id": $UUID,
    "method": "sendTransaction",
    "params": [
        "<base64_encoded_tx>",
        { "encoding": "base64" }
    ]
}'
$UUID is a unique ID generated by the user for request identification.

Transaction Tip

Each transaction requires a system transfer instruction to one of the Stellium tip addresses below with a minimum tip of 0.001 SOL. Use any of these Solana addresses for transaction tips to improve priority:

Keep Alive

To keep your connection warm, send a lightweight GET request to the same API URL you use for sendTransaction. Use this as a heartbeat every 60 seconds when traffic is idle. It does not submit a transaction.
