We vote **FOR** the proposal on Tally. We maintain our rationales below for each individual update and support a package of those updates to be deployed as “Bianca”. We appreciate the proper audits on each implementation and OpenZeppelin’s reviews as a part of ARDC works. > [@AIP: Activate Stylus and Enable Next-Gen WebAssembly Smart Contracts (ArbOS 30)](https://forum.arbitrum.foundation/t/aip-activate-stylus-and-enable-next-gen-webassembly-smart-contracts-arbos-30/22970/34): > > We vote FOR the proposal on its Snapshot. Stylus is an ambitious, yet rational innovation that Offchain Labs has developed to make Arbitrum even more attractive to Rust and C++ developers. We’d hope that the technology will be integrated into other L2 chains so that the smart contract composability will remain as we have on the EVM platforms. > [@AIP: Nova Fee Router Proposal (ArbOS 30)](https://forum.arbitrum.foundation/t/aip-nova-fee-router-proposal-arbos-30/23310/25): > > We vote FOR the proposal on its Snapshot. We consider it rather a fix to apply the change and simplify the fee related operations for the DAO. > [@AIP: Support RIP-7212 for Account Abstraction Wallets (ArbOS 30)](https://forum.arbitrum.foundation/t/aip-support-rip-7212-for-account-abstraction-wallets-arbos-30/23298/33): > > We vote FOR the proposal on its Snapshot. RIP-7212 has been well-supported by the whole Ethereum community and other L2s will certainly introduce it on their chains. This enables more secure smart wallets to be easily utilized on the L2 environments, which is a clear win for the better UX. We are particularly excited to see Stylus finally going live! --- _[View the full topic](https://forum.arbitrum.foundation/t/aip-arbos-31-bianca-activation-of-arbitrum-stylus-rip-7212-support-nova-fee-router-proposal/25904)._
