Arbitrum Orbit allows Developers to permissionlessly launch their own custom chains that settle on Arbitrum One. It is the technology behind the Superposition Layer-3, and utilises Arbitrum's Nitro Tech Stack to offer high throughput, low transaction costs and more efficient memory usage.
It allows Developers to choose a custom ERC-20 gas token for their chain, modular data availability solutions (such as Conduit), self governance as well as utilising Arbitrum Stylus to write Smart Contracts using the Stylus Rust SDK.
