2 Polls Closing September 4, 2025
[CONSTITUTIONAL] AIP: ArbOS Version 50 Dia
Summary: This poll asks ARB holders if they support upgrading Arbitrum One and Arbitrum Nova to ArbOS v50 “Dia”.
This upgrade contains some minor bug fixes and support for some features in the upcoming “Fusaka” Ethereum hard fork. EIPs that will be supported include EIP-2537, which was not included in previous ArbOS v40 “Callisto”. A full list of which Fusaka EIPs will be supported and which will not can be found here.
An audit will be conducted and published by Trail of Bits and the upgrade deployed to private and public testnets prior to moving forward to a Tally vote for execution.
Recommendation: Vote For. This vote authorizes finalizing the code base, auditing, and testnet deployment. Pending success of those items, a final vote to execute would also receive our support.
[CONSTITUTIONAL] Remove Cost Cap, Update Executors, Disable Legacy USDT Bridge
Summary: This poll asks ARB holders if they support a bundled proposal of several housekeeping items. These consist of raising gas costs on Arbitrum Nova, simplifying the Upgrade Executor contract workflow, and disabling the obsolete USDT Bridge.
Recommendation: Vote For. These are all expected items that were intended to be implemented. They were bundled due to their uncontroversial nature and the difficulty of passing Constitutional-level proposals.
