net_version - GIWA

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

This method returns the network ID as a decimal string. On GIWA the network ID matches the chain ID (91342) and is used to confirm which network an endpoint is connected to.

Parameters

This method does not require any parameters. Send the request with an empty params array.

Request

cURL

curl --location --request POST 'https://shared.ap-southeast-1.getblock.io/<ACCESS-TOKEN>/' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc": "2.0",
    "method": "net_version",
    "params": [],
    "id": "getblock.io"
}'

Axios

example.js

const axios = require('axios');

const response = await axios.post('https://shared.ap-southeast-1.getblock.io/<ACCESS-TOKEN>/', {
    jsonrpc: '2.0',
    method: 'net_version',
    params: [],
    id: 'getblock.io'
}, {
    headers: { 'Content-Type': 'application/json' }
});

console.log(response.data.result);

Request

example.py

import requests

response = requests.post(
    'https://shared.ap-southeast-1.getblock.io/<ACCESS-TOKEN>/',
    headers={'Content-Type': 'application/json'},
    json={
        'jsonrpc': '2.0',
        'method': 'net_version',
        'params': [],
        'id': 'getblock.io'
    }
)

print(response.json())

Rust

example.rs

use reqwest::Client;
use serde_json::{json, Value};

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

    let response = client
        .post("https://shared.ap-southeast-1.getblock.io/<ACCESS-TOKEN>/")
        .header("Content-Type", "application/json")
        .json(&json!({
            "jsonrpc": "2.0",
            "method": "net_version",
            "params": [],
            "id": "getblock.io"
        }))
        .send()
        .await?
        .json::<Value>()
        .await?;

    println!("Result: {}", response["result"]);
    Ok(())
}

Response

{
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "result": "91342"
}

Response Parameters

Parameter	Type	Description
jsonrpc	string	JSON-RPC protocol version ("2.0")
id	string	Request identifier matching the request
result	string	Network ID as a decimal string (91342 for GIWA)

Use Cases

• Network Confirmation: Verify a wallet or dApp is pointed at GIWA and not another chain

• Environment Guards: Reject transactions when the connected network ID is unexpected

• Multi-Chain Routing: Select the correct contract addresses based on the returned network ID

• Connection Checks: Confirm an endpoint responds before issuing heavier calls

Error Handling

Error Code	Message	Description
-32603	Internal error	The node failed to return the network ID
-32601	Method not found	The net module is disabled on the client build

Web3 Integration

Ethers.js

ethers-example.js

import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider('https://shared.ap-southeast-1.getblock.io/<ACCESS-TOKEN>/');

const network = await provider.getNetwork();
console.log(network.chainId);

Viem

viem-example.js

import { createPublicClient, http } from 'viem';

const client = createPublicClient({
  transport: http('https://shared.ap-southeast-1.getblock.io/<ACCESS-TOKEN>/')
});

const networkId = await client.request({ method: 'net_version' });
