This Smart RPC Load Balancer simplifies regional load balancing for RPC-driven applications. Our simple and easy to use dashboard allows you to quickly add fault tolerance to your application in as few as 2 steps.

By directly offering reputable providers like QuickNode and your preferred custom RPC providers, we streamline the distribution of RPC requests across numerous nodes.

Our Smart RPC Load Balancer bolsters reliability by automatically routing requests to active RPC endpoints with the highest block height, ensuring uninterrupted service delivery. This proactive approach minimizes downtime, providing you with a dependable RPC workload experience.

Additionally, our load balancer optimizes regional distribution and caching based on blockchain block times, resulting in latency, efficiency and overall system performance.

You must login to the Backpac Dashboard to obtain a Backpac Endpoint and API Key

• Provision multiple QuickNode endpoints of the same Blockchain Network.

These endpoints will be load balanced across. Each endpoint will be added to the default target group automatically.

• Login into the Backpac dashboard to get an API Key and Backpac endpoint.

For QuickNode users, Backpac automatically configures two default application API Keys.

• Example Endpoint: https://ethereum-mainnet-mr.qn.backpac.xyz/{APPAPIKEY}

• Just start using the endpoint provided by Backpac for your RPC request.

The Backpac endpoint will load balance RPC request across the provisioned QuickNode endpoints.

• (optional) Add additional RPC node provider endpoints.

Endpoint & API KEY

Application API Key

• API KEY: The key to authenticate request.

• HTTPS: The protocol of the endpoint.

• HTTPS | API KEY: The application endpoint and API Key.

eth_getTransactionByHash

eth_getTransactionByHash Returns the information about a transaction from a transaction hash. Below is an example using a Backpac endpoint and application API Key.

var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/json");

var raw = JSON.stringify({
  "method": "eth_getTransactionByHash",
  "params": [
    "0xb1fac2cb5074a4eda8296faebe3b5a3c10b48947dd9a738b2fdf859be0e1fbaf"
  ],
  "id": 1,
  "jsonrpc": "2.0"
});

var requestOptions = {
  method: 'POST',
  headers: myHeaders,
  body: raw,
  redirect: 'follow'
};

fetch("https://ethereum-mainnet-mr.qn.backpac.xyz/{APP_API_KEY}", requestOptions)
  .then(response => response.text())
  .then(result => console.log(result))
  .catch(error => console.log('error', error));

API Key types:

1. Direct: A primary endpoint with failover to a target group of multiple RPC Endpoints. **Best for the lowest latency. When you provision multiple QuickNode endpoints. They will be added to the default target group.

2. Rules: The target group is selected based on the listener rules evaluated for the Blockchain Network. By default, only a direct rule is created.
