The Challenge: Unreliable Transaction Landing

In the Solana ecosystem, transaction landing can be unsatisfying due to:
  • Blockchain congestion during peak periods
  • Network latency
  • Varying infrastructure quality
This uncertainty particularly affects power users like traders, bots, and dApps where execution quality and consistency is critical.

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

Stellium uses staked connections and automatically submits transactions to validator leaders through our low latency networks. Stellium optimizes the whole newtorking stack to improve landing rate and tx finality times.

​
API Usage

We use the standard Solana sendTransaction format in our API: 
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.

​
Regions

We provide Frankfurt, Amsterdam, New York, London, Tokyo and Singapore region endpoints.
Contact us for access to the endpoint or to request additional regions. Please avoid testing on other regions.
