⚡️ sup - Superchain CLI

sup is a CLI tool to help deploy and manage contracts on the Superchain.

WIP This is a work in progress it is not ready to be consumed!

✨ Features

• 🤝 works with existing foundry projects (sup is a companion, not a replacement to foundry)
• 🕹️ interactive mode (no more juggling cli flags)
• 🚀 deploy and verify contracts to multiple chains at once
• 💸 bridge funds to multiple chains at once (no more "how do I get gas on all of these chains?")
• 🔑 use connected wallets (Metamask / WalletConnect) to deploy contracts (no more .env files with private keys)

🚀 Getting started

1. Install prerequisites: node.js

RPC URL Override

You can override the RPC URL by setting the {name}_RPC_URL environment variable.

For example, lets say we wanted to override OP & Base Mainnet

OP_RPC_URL=...
BASE_RPC_URL=...

❓ Is sup a replacement for foundry?

Nope, foundry is great! sup is meant to be a lightweight add-on tool to help with the annoyances of multichain development. It works with your existing foundry project, and expects you to use foundry to build contracts. It even emits the same broadcast artifacts when you deploy contracts.
