Pure Rust implementation of Arbitrum sequencer feed reader with built-in transaction decoding and MEV features
This Rust implementation is designed for a high number of concurrent connections and faster performance than the original Go implementation, with MEV-specific features.
To use this sequencer-client, you'll need Tokio as your main runtime.
Here is a basic example.
use crossbeam_channel::unbounded;
use sequencer_client::feed_clients::RelayClients;
#[tokio::main]
async fn main() {
// Create a channel to receive messages from the feed client
let (sender, receiver) = unbounded();
// Create a new relay client and start reader + connection maintainer
let relay_client = RelayClients::new("wss://arb1.arbitrum.io/feed", 42161, 2, 1, sender)
.expect("Failed to create relay client");
tokio::spawn(RelayClients::start_reader(relay_client));
// To prevent duplicate messages
let mut highest_seq_number: i64 = 0;
loop {
let data = receiver
.recv()
.expect("Failed to receive data from feed client");
let msg_seq_num = data.messages[0].sequence_number;
if highest_seq_number >= msg_seq_num {
continue;
}
highest_seq_number = msg_seq_num;
info!("Received message, sequencer_number: {:?} ", msg_seq_num);
}
}Currently, the sequencer-reader does not have full transaction decoding and only includes the MEV specific parts
