use ethers::core::rand::thread_rng;
use ethers::prelude::*;
use ethers_flashbots::*;
use std::convert::TryFrom;
use url::Url;#[tokio::main]
async fn main() -> Result<()> {
// Connect to the network
let provider = Provider::::try_from("https://mainnet.eth.aragon.network")?;// This is your searcher identity
let bundle_signer = LocalWallet::new(&mut thread_rng());
// This signs transactions
let wallet = LocalWallet::new(&mut thread_rng());// Add signer and Flashbots middleware
let client = SignerMiddleware::new(
FlashbotsMiddleware::new(
provider,
Url::parse("https://relay.flashbots.net")?,
bundle_signer,
),
wallet,
);// Pay Vitalik using a Flashbots bundle!
let tx = TransactionRequest::pay("vitalik.eth", 100);
let pending_tx = client.send_transaction(tx, None).await?;// Get the receipt
let receipt = pending_tx
.await?
.ok_or_else(|| eyre::format_err!("tx not included"))?;
let tx = client.get_transaction(receipt.transaction_hash).await?;println!("Sent transaction: {}\n", serde_json::to_string(&tx)?);
println!("Receipt: {}\n", serde_json::to_string(&receipt)?);Ok(())
