### Install ethers-flashbots

Source: https://github.com/onbjerg/ethers-flashbots/blob/master/README.md

Add the ethers-flashbots crate to your Cargo.toml file to include it in your Rust project. This example shows how to add the development version from a Git repository.

```toml
# This is the development version, for the stable release refer
# to crates.io
ethers-flashbots = { git = "https://github.com/onbjerg/ethers-flashbots" }
```

--------------------------------

### Update Changelog

Source: https://github.com/onbjerg/ethers-flashbots/blob/master/RELEASE.md

This task requires updating the `CHANGELOG.md` file. Specifically, the 'Unreleased' section needs to be moved to a new header corresponding to the new version, and a comparison link to the previous version should be added.

```markdown
Move "Unreleased" section in [CHANGELOG.md](./CHANGELOG.md) into a header with the new version, and add a link at the bottom of the CHANGELOG to compares that version to HEAD
```

--------------------------------

### Publish New Version

Source: https://github.com/onbjerg/ethers-flashbots/blob/master/RELEASE.md

The final step in the release process is to push the committed and tagged changes to the remote repository and then publish the new version of the crate using the `cargo publish` command.

```rust
Push the changes and run `cargo publish`
```

--------------------------------

### Commit and Tag Release

Source: https://github.com/onbjerg/ethers-flashbots/blob/master/RELEASE.md

After updating the version and changelog, the changes must be committed to version control. A tag should then be created for this commit, using the version number without any prefix (e.g., '0.1.0', not 'v0.1.0').

```git
Commit those changes and tag that commit with the version number (**no `v` prefix!**)
```

--------------------------------

### Update Version in Cargo.toml

Source: https://github.com/onbjerg/ethers-flashbots/blob/master/RELEASE.md

This step involves modifying the `Cargo.toml` file to reflect the new version number of the project. This is a standard practice in Rust projects managed by Cargo.

```rust
Update version in `Cargo.toml`
```

--------------------------------

### Send Transaction Bundle with Ethers Flashbots

Source: https://github.com/onbjerg/ethers-flashbots/blob/master/README.md

Demonstrates how to use the ethers-flashbots middleware to send a transaction bundle via Flashbots. It covers connecting to an Ethereum network, setting up signers for the bundle and transactions, creating a Flashbots middleware client, and sending a transaction for prioritized inclusion.

```rust
use eyre::Result;
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::<Http>::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(())
}
```
