MEVBlocker Alloy Extension

A Rust library that extends Alloy with MEVBlocker's custom RPC methods for subscribing to unsigned transactions.

Overview

This library provides a trait extension for Alloy providers to support MEVBlocker's mevblocker_partialPendingTransactions subscription, which streams unsigned pending transactions missing signature fields (v, r, s).

Features

• 🔌 Seamless integration with Alloy providers
• 📡 Subscribe to MEVBlocker's partial pending transactions via WebSocket
• 🎯 Deserializes transaction data into Alloy's TransactionRequest type
• ⚡ Compatible with Alloy's async streaming interface

Installation

Add this to your Cargo.toml:

[dependencies]
mevblocker-ext = "0.1.0"
alloy = { version = "1.0", features = ["pubsub"] }
futures-util = "0.3"
tokio = { version = "1.0", features = ["rt", "macros"] }
eyre = "0.6"

Usage

use alloy::providers::{ProviderBuilder, WsConnect};
use futures_util::StreamExt;
use mevblocker_ext::MevblockerApi;
use eyre::Result;

#[tokio::main]
async fn main() -> Result<()> {
    let rpc_url = "wss://searchers.mevblocker.io";
    let ws = WsConnect::new(rpc_url);
    let provider = ProviderBuilder::new().connect_ws(ws).await?;

    let sub = provider.subscribe_mevblocker_pending_transactions().await?;
    let mut stream = sub.into_stream();

    while let Some(tx) = stream.next().await {
        println!("Unsigned transaction: {tx:#?}");
    }

    Ok(())
}
