reqwest

1

Create a new Rust project:

cargo new radius_quickstart
cd radius_quickstart

2

Add the following dependencies to your Cargo.tomlfile:

[dependencies]
reqwest = { version = "0.11", features = ["json"] }
tokio = { version = "1", features = ["full"] }
serde_json = "1.0"

3

Replace the contents of src/main.rs with the following code:

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

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let url = "https://rpc.testnet.tryradi.us/<YOUR-RPC-ENDPOINT>";

    let client = Client::new();
    let response = client.post(url)
        .json(&json!({
            "jsonrpc": "2.0",
            "method": "eth_blockNumber",
            "params": [],
            "id": 1
        }))
        .send()
        .await?;

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

    Ok(())
}

    let rpc_url = "https://rpc.testnet.tryradi.us/<YOUR-RPC-ENDPOINT>".parse()?;
    let provider = ProviderBuilder::new().on_http(rpc_url);

    // Get the current block number as a test
    let block_number = provider.get_block_number().await?;
    println!("Current block number: {}", block_number);
