[AIP-36] Optimism Deployment

Authors: Fry, 0xMaha, 0xAhtle, Hephyrius

Summary

We are pleased to present a proposal for Aura Finance's strategic cross-chain deployment onto Optimism. This significant initiative is the second deployment in Aura's cross chain rollout and aims to unlock opportunities for Aura's growth and expand our presence and level up the Balancer ecosystem.

After the successful launch on Arbtrium and our continued commitment to go cross-chain, Aura Finance is now gearing up to deploy on Optimism. This move will offer users the ability to deposit BPTs (Balancer Pool Tokens) on Optimism and take advantage of the cross-chain veBAL delegated boost. Additionally, it will facilitate the seamless bridging of AURA tokens from mainnet to Optimism, further enhancing accessibility and flexibility for our community.

Audits and testing

As always, Aura takes security extremely seriously. All new contracts and integrations have been audited. Aura currently has completed two audits from Halborn and Zellic. All new contracts have also received a rigorous testing treatment. Our new contracts have 100% unit test coverage as well as fork tests and fuzz tests.

Specification

Should this AIP be approved, the following changes will be implemented:

1. Cross chain contracts deployed on Optimism.
2. Call setTrustedRemote on the AuraOFT with the optimism AuraOFT remote data
