Notices & Upgrades

This section lists network upgrade notices and configuration changes for Robinhood Chain.

• Node operators should monitor this page — some upgrades require you to update your node before a scheduled activation.
• Developers should review notices for any behavior changes that could affect contracts or integrations.
• End users generally don't need to take action.

How network upgrades work

Robinhood Chain runs Arbitrum Nitro and periodically upgrades its ArbOS version. These upgrades activate onchain at a scheduled time. Before each activation, node operators must run a compatible Nitro node version — an un-upgraded node stops cleanly at the upgrade block and resumes normally once updated, with no data loss or resync required. Most upgrades require no action from dApp developers or end users, though some include EVM or behavior changes worth reviewing.
