The following reflects the views of GMX’s Governance Committee, and is based on the combined research, evaluation, consensus, and ideation of various committee members.
We are in favour of this proposal.
With the advent of Spectra and its technical changes, ArbOS Callisto aims to devise an upgrade that will definitely create added value for the ecosystem. Especially so for account abstraction applications. The utilisation of Spectra’s upgrade — incorporating transaction sponsorships for covering user gas expenses with auth signatures, batching transactions to eliminate additional user friction for using apps (like having to pay for approvals and do a trade), and privilege de-escalation — can reduce security risks for users.
Additionally, the other upgrades are very clear: EIP-2537 for improved security for applications, EIP-2935 serving the data retrieval of block hashes to configure on top of clients, and Stylus fix amount to a reasonable request.
Noting that there are technical considerations pertaining to the various environments (into Nitro) and sequence of implementations (for audits and test developments), we do believe that this effort is worthwhile and will be completed diligently. Therefore, we are for approval of the proposal.
