Customizations require expertise
Customizing your chain is a core benefit of building with Arbitrum chains. We strongly recommend that teams interested in customizations work alongside a partner with ArbOS and Nitro software expertise, such as a Rollup-as-a-Service team.
Working alongside an experienced Arbitrum chain operator can help your team navigate the complex tradeoff space of rollup customizations, which can include performance, security, and cost considerations. Offchain Labs is positioned to train and enable Rollup-as-a-Service in their work with clients to scale support to the Arbitrum chain ecosystem as a whole. As such, Offchain Labs does not necessarily have the capacity to review code changes made by individual Arbitrum chains.
We encourage you to leverage your in-house expertise, collaborate with expert partners, and allocate appropriate resources for both an initial implementation (including an audit) and ongoing maintenance and security management of your customization.
