How to Deploy an Arbitrum Chain

as easily as floating through the cosmos

Chain Configurator

Chain Type

Parent Chain

Parent Chain RPC URL

Gas Token

Deployer Private Key

Private key of the account that will be used to deploy the chain. You might wanna put this in an environment variable!

Chain ID

Your chain's unique identifier. It differentiates your chain from others in the ecosystem.

Chain Name

This name provides a way for people to distinguish your Arbitrum chain from other Arbitrum chains. You'll want to make this a name that you can easily remember, and that your users and developers will recognize.

Initial Chain Owner

Account address responsible for deploying, owning, and managing your Arbitrum chain's base contracts on its parent chain.
