We are voting for this proposal.
As an Ethereum L2, we believe it is essential that Arbitrum keeps its protocol closely aligned with Ethereum’s roadmap and upgrades. ArbOS 50 Dia addresses the majority of the necessary changes required for the upcoming Fusaka hard fork, and we see this as a critical step to maintain strong compatibility with Ethereum at the protocol level.
The detailed evaluation of technical risks will take place after the upgrade is developed and audited. For now, we do not see such potential risks as a decisive concern during the discussion phase.
We also welcome the new features introduced, particularly Native Mint/Burn and the groundwork for multi-gas tracking. Native Mint/Burn represents an important advancement for optimizing the cross-chain user experience, while the multi-gas instrumentation is a meaningful preparation for a more adaptive and stable fee model in the future.
Finally, while it is unfortunate that EIP-7907 has been deferred, especially considering its relevance for advanced use cases such as FHE and Stylus, we remain optimistic about further progress on this front in future upgrades.
