Struct BroadcasterMiddleware

pub struct BroadcasterMiddleware<M, S> { /* private fields */ }

A middleware used to broadcast bundles to multiple builders.

NOTE: This middleware does NOT sign your transactions. Use another method to sign your transactions, and then forward the signed transactions to the middleware.

You can either send custom bundles (see BundleRequest) or send transactions as you normally would (see Middleware::send_transaction) from another middleware.

If you use Middleware::send_transaction then a bundle will be constructed for you with the following assumptions:

• You do not want to allow the transaction to revert
• You do not care to set a minimum or maximum timestamp for the bundle
• The block you are targetting with your bundle is the next block
• You do not want to simulate the bundle before sending to the builder

Example

use ethers::prelude::*;
use std::convert::TryFrom;
use ethers_flashbots::BroadcasterMiddleware;
use url::Url;

let provider = Provider::<Http>::try_from("http://localhost:8545")
    .expect("Could not instantiate HTTP provider");

// Used to sign Flashbots relay requests - this is your searcher identity
let signer: LocalWallet = "380eb0f3d505f087e438eca80bc4df9a7faa24f868e69fc0440261a0fc0567dc"
    .parse()?;

// Used to sign transactions
let wallet: LocalWallet = "380eb0f3d505f087e438eca80bc4df9a7faa24f868e69fc0440261a0fc0567dc"
    .parse()?;

// Note: The order is important! You want the signer
// middleware to sign your transactions *before* they
// are sent to your Flashbots middleware.
let mut client = SignerMiddleware::new(
    BroadcasterMiddleware::new(
        provider,
        vec![Url::parse("https://rpc.titanbuilder.xyz")?, Url::parse("https://relay.flashbots.net")?],
        Url::parse("https://relay.flashbots.net")?,
        signer
    ),
    wallet
);

// This transaction will now be sent as a Flashbots bundle!
let tx = TransactionRequest::pay("vitalik.eth", 100);
let pending_tx = client.send_transaction(tx, None).await?;
