L2 Micro Service

Rust HTTP micro-service provides OP Stack & Arbitrum information including block hash requested by block number.

Quick Start

First, you need to run the monitoring service and your DB_URL should be full of data that got from monitoring.

Then you can run a server that exposes endpoint to request output_root

cargo run -p l2-micro-service

After your Rocket has launched, you need to send l2_block and network to get output_root for that block, and network should be compatible with table name:

#[post("/output_root")]

{
  "name": "optimism_mainnet",
  "l2_block": 105240464
}
