net_version - AVAX

Example code for the net_version JSON-RPC method. Complete guide on how to use net_version JSON-RPC in GetBlock Web3 documentation.

Returns the current network ID as a decimal string. For Avalanche C-Chain mainnet: "43114"; for Fuji testnet: "43113". Decimal string, unlike eth_chainId which returns hex.

Parameters

None

Request Example

curl --location --request POST 'https://go.getblock.io/<ACCESS-TOKEN>/ext/bc/C/rpc' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc": "2.0",
    "method": "net_version",
    "params": [],
    "id": "getblock.io"
}'

import requests
import json

url = "https://go.getblock.io/<ACCESS-TOKEN>/ext/bc/C/rpc"

payload = json.dumps({
    "jsonrpc": "2.0",
    "method": "net_version",
    "params": [],
    "id": "getblock.io"
})

headers = {
    'Content-Type': 'application/json'
}

response = requests.post(url, headers=headers, data=payload)
print(response.text)

use reqwest::Client;
use serde_json::json;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new();

    let payload = json!({
        "jsonrpc": "2.0",
        "method": "net_version",
        "params": [],
        "id": "getblock.io"
});

    let response = client
        .post("https://go.getblock.io/<ACCESS-TOKEN>/ext/bc/C/rpc")
        .header("Content-Type", "application/json")
        .json(&payload)
        .send()
        .await?;

    let result: serde_json::Value = response.json().await?;
    println!("{:#?}", result);

    Ok(())
}

Response Example

{
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "result": "43114"
}

Response Parameters

Field

Description

result

string

Network ID as a decimal string (43114 mainnet, 43113 Fuji testnet)

Use Cases

Detecting which network the node is on
Legacy compatibility — older tools use net_version over eth_chainId

import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider('https://go.getblock.io/<ACCESS-TOKEN>/ext/bc/C/rpc');

// Most methods are exposed directly on the provider.
// For raw access, use provider.send(method, params).
const result = await provider.send('net_version', []);
console.log(result);

import { createPublicClient, http } from 'viem';
import { avalanche } from 'viem/chains';

const client = createPublicClient({
    chain: avalanche,
    transport: http('https://go.getblock.io/<ACCESS-TOKEN>/ext/bc/C/rpc')
});

const result = await client.request({ method: 'net_version', params: [] });
console.log(result);
