system_version

Description

Returns the node implementation string, including the binary name, semantic version, and commit hash. Monitor this after runtime upgrades or when validating collator fleets.

Parameters

This method does not require parameters.

Returns

Field	Type	Description
result	string	Node implementation identifier

Request Example

{
  "jsonrpc": "2.0",
  "method": "system_version",
  "params": [],
  "id": 1
}

Response Example

{
  "jsonrpc": "2.0",
  "result": "bifrost-node/v0.21.1-78b9700/x86_64-linux-gnu (Polkadot API 1.3.0)",
  "id": 1
}

Code Examples

JavaScript

const provider = new WsProvider('wss://api-bifrost-polkadot.n.dwellir.com/YOUR_API_KEY');
const api = await ApiPromise.create({ provider });

const version = await api.rpc.system.version();
console.log('Node version:', version.toString());

Python

import requests
import json

payload = {
    "jsonrpc": "2.0",
    "method": "system_version",
    "params": [],
    "id": 1
}

resp = requests.post(
    "https://api-bifrost-polkadot.n.dwellir.com/YOUR_API_KEY",
    headers={"Content-Type": "application/json"},
    data=json.dumps(payload)
)
print(resp.json()["result"])

Rust

use subxt::{config::substrate::SubstrateConfig, OnlineClient};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let api = OnlineClient::<SubstrateConfig>::from_url("wss://api-bifrost-polkadot.n.dwellir.com/YOUR_API_KEY").await?;
    let version = api.rpc().system_version().await?;
    println!("Bifrost node version: {}", version);
    Ok(())
}

Operational Guidance

• Track version strings during rolling upgrades to ensure all collators advertise the expected release (e.g., v0.21.1).
• Combine with state_getRuntimeVersion to confirm the runtime spec and transaction versions align with network expectations.
