Optimism Highlights 🔴✨

HAI Multi-Collateral RAI On Optimism
Ameen Soleimani announced plans for HAI, a multi-collateral RAI fork on Optimism. The dollar-pegged stablecoin will initially be backed by ETH and wstETH. RAI, rETH, and OP. UNI will be supported as collateral at a later date. HAI will have its own governance token called KITE, allowing holders to add or remove collateral types. According to Soleimani, the equilibrium redemption rates for HAI will trend positive, leading to an increase in the stablecoin’s price over time. A testnet for HAI is expected to launch on June 9th with a mainnet release planned for July. HAI’s predecessor RAI, is a governance-minimized floating stablecoin that is overcollateralized by ether.

ENS Introduces A New Domain Manager

ENS released a preview of its new domain manager on alpha.ens.domains. The new app allows users to manage subdomains, renewals, content records, and additional features introduced by the ENS wrapper contract. Users are required to upgrade their domains to the new public resolver in order to access the wrapper features. The new app is more user-centric and introduces the ability to purchase domains with a credit card via MoonPay. The registrant and controller addresses have also been renamed to owner and manager. The new release is set to be rolled out on the main app.ens.domains dapp page on Monday.

Prysm, Geth, And Nethermind Client Updates

Prysm released v4.0.3 of its consensus layer client. The release includes bug fixes in the external block builder code path for users with mev-boost. The release also addresses key manager issues and includes a REST API endpoint for the beacon chain client’s GetChainHead. The release is a recommended upgrade for all Prysm users. Geth released v1.11.6 of its execution client coined as Azimir. Azimir includes log management features such as log rotation and a new log output format called logfmt. Nethermind also released ​​v1.17.4 of its client, which is intended for nodes that are syncing from scratch. Nethermind v1.17.3 users are advised to wait for the release of v1.18.0 before upgrading.

EigenLayer Initial Security Audit

Consensys Diligence completed an initial security audit for restaking protocol EigenLayer. The audit found zero critical issues and a few minor severity issues, including a potential vulnerability in the StrategyBase contract and inconsistent data types for block numbers. EigenLabs has since responded to and addressed the found issues. EigenLayer allows stakers to secure additional protocols by pointing their validator withdrawal credentials to their EigenLayer smart contract. An initial EigenLayer testnet was deployed earlier this month. EigenLayer is undergoing additional audits and plans to launch a code4rena audit contest ahead of its mainnet deployment later this year.

First Post-Shanghai Devnet For EIP-4844

Ethereum core developers are working toward the first post-Shanghai devnet for EIP-4844, marking the 5th devent for the EIP. The new devnet will ban zero blob transactions and will decouple blobs from blocks. Ethereum’s next consensus layer upgrade, known as Deneb, will focus almost entirely on the implementation of EIP-4844 blob transactions.
