Play with Code Examples 🎮

💫 Getting Started

Import the library:

use pwr_rs::{
    Wallet, 
    RPC, 
};

Set your RPC node:

let rpc = RPC::new("https://pwrrpc.pwrlabs.io/").await.unwrap();

Generate a new wallet:

let private_key = "0xac0974bec...f80";
let wallet = Wallet::from_hex(&private_key).unwrap();

Get wallet address:

let address = wallet.address();

Get wallet balance:

let balance = wallet.get_balance().await;

Transfer PWR tokens:

/// recipientAddress: 20 bytes address without `0x`
wallet.transfer_pwr(1000, "recipientAddress".into()).await;

Sending a transcation to the PWR Chain returns a Response object, which specified if the transaction was a success, and returns relevant data. If the transaction was a success, you can retrieive the transaction hash, if it failed, you can fetch the error.

use pwr_rs::Wallet;
async fn main() {
    let private_key = "0xac0974bec...f80";
    let wallet = Wallet::from_hex(&private_key).unwrap();

    /// recipientAddress: 20 bytes address without `0x`
    let trx_hash = wallet.transfer_pwr(1000, "recipientAddress".into()).await;
    println!("Transaction Hash: {trx_hash}");
}

Send data to a VM:

use pwr_rs::Wallet;
async fn main() {
    let private_key = "0xac0974bec...f80";
    let wallet = Wallet::from_hex(&private_key).unwrap();

    let data = vec!["Hello World!"];
    let data_as_bytes: Vec<u8> = data.into_iter().flat_map(|s| s.as_bytes().to_vec()).collect();

    let tx_hash = wallet.send_vm_data(123, data_as_bytes).await;
    println!("Transaction Hash: {tx_hash}");
}

Other Static Calls

Get RPC Node Url:

Returns currently set RPC node URL.

let url = rpc.node_url();

**Get Fee Per Byte: **

Gets the latest fee-per-byte rate.

let fee = rpc.fee_per_byte();

Get Balance Of Address:

Gets the balance of a specific address.

let balance = rpc.balance_of_address("0x...").await.unwrap();

Get Nonce Of Address:

Gets the nonce/transaction count of a specific address.

let nonce = rpc.nonce_of_address("0x...").await.unwrap();
