Interchain messaging protocol Hyperlane launched its EigenLayer Actively Validated Service (AVS) on mainnet. The Hyperlane AVS introduces a restaked interoperability framework that uses restaked ETH to secure cross-rollup interactions. It provides rollups with access to fast, cost-effective, and economically secured bridge transfers. Hyperlane aims to address the fragmentation and security issues of bridging between rollups. Hyperlane enables the seamless passing of arbitrary messages and cross-chain contract calls and allows applications to set their own security measures. Hyperlane also supports permissionless expansion into different virtual machines.

Paradigm released Reth 1.0, the first production-ready version of its Ethereum execution client written in Rust. Reth enhances the stability of Ethereum, featuring improvements in sync time, storage, and RPC throughput. Reth can fully synchronize an archival node from genesis in 50 hours, compared to several days for other clients. Paradigm says Reth is able to efficiently utilize resources across various operational settings. The implementation is inspired by clients like Geth, Erigon, and Akula. The upcoming Reth 1.1 release will include support for the OP Stack. Paradigm is also working on shipping support for the Pectra hardfork.

Privy introduced support for cross-app wallets, a feature that allows users to use their existing embedded wallet to log in to other applications. The feature enables interoperability by allowing users to access and manage their assets across apps. Once connected, users can verify ownership, sign messages, and execute transactions. The implementation includes initial integrations with app providers such as Zora, OpenSea, Fantasy, and Adimverse. Privy is an authentication tool provider for integrating account abstraction features. In a future update, Privy plans to extend support for adding embedded wallets into connector libraries.

Harpie expanded its wallet security tools to include support for Base, Arbitrum, and Polygon. The expansion allows users to track their security score, activate two-factor authentication (2FA), and revoke token approvals on the new Layer 2 networks. The expansion incorporates Harpie’s threat address system, which includes over 100,000 addresses. To enable 2FA, users simply add and use Harpie’s RPC for their chosen network. The system monitors user transactions and, upon detecting a suspicious transaction, halts its onchain execution and notifies the user. Users can then decide whether to proceed with or reject the flagged transaction. Harpie aims to address the lack of security tools available for L2s.

Rainbow Wallet launched ETH rewards for participants in its points program. The top 10,000 Rainbow points earners were awarded an initial share of 20 ETH, which can be claimed on the app's points page. Every Tuesday, Rainbow will distribute a portion of its platform revenue in ETH to the weekly top 1,000 points earners. The introduction of ETH rewards represents the initial phase of Rainbow’s three-phase launch plan. Rainbow acknowledged existing points earners, hinting that a snapshot of their contributions has been taken. Rainbow is a mobile and browser-based EVM wallet, targeting existing Metamask users.

Blast, an optimistic L2 rollup, released the tokenomics for its native BLAST token, scheduled to launch on June 26 at 10 AM EST. The rollout will distribute 17% of the 1 billion total token supply as an initial airdrop to users who earned points on Blast and Blur. The community is allocated 50% of the token supply, which includes the initial 17% airdrop. Core contributors and investors are allocated 42%, and the Blast Foundation is allocated 8%. Since opening deposits in November 2023, Blast has reached a TVL of $2.9 billion from 1.5 million addresses. As one of the pioneering rollups to implement native yield, Blast holds ETH deposits into LSTs and channels stablecoin deposits into protocols like MakerDAO to earn yield.

Rollup infrastructure provider Conduit raised $37 million in a Series A funding round, co-led by Paradigm and Haun Ventures. Conduit's founder, Andrew Huang, says that since its inception in 2022, Conduit has facilitated 287 rollup deployments. Rollups deployed through Conduit secure over $1.2 billion in total value locked. Conduit plans to use the fresh capital to expand its engineering team and enhance its rollup-native infrastructure integrations.

Vyper, a pythonic EVM smart contract language, released version 0.4.0. The release introduces a new module system that enhances code reuse across smart contracts. The system features two types of library modules: stateless and stateful. Stateless modules can define functions, events, and constants across contracts without retaining state between calls or transactions. On the other hand, stateful modules can bundle together functions and variables, and support an ownership system that manages access and permissions within the module. Stateful modules are ideal for scenarios where shared data or restricted access is needed. Among other features, Vyper v0.4.0 also introduces Venom, a new optimization pipeline designed for the EVM. Vyper is the second-most popular programming language among Ethereum developers.

The Arbitrum Stable Treasury Endowment Program (STEP) committee, consisting of GFXlabs, NorthLakesLegal, Nethermind, Steakhouse, and Karpatkey, recommended six real-world asset (RWA) products for the strategic investment of 35 million ARB tokens to diversify the Arbitrum DAO treasury. The selected RWA products and allocations include 11 million ARB for BlackRock’s BUIDL Fund via Securitize, 6 million ARB each for Ondo’s USDY and Superstate’s USTB, and 4 million ARB each for Mountain USDM OpenEden TBill, and Backed Finance bIB01 product. Arbitrum governance will vote next month to approve the recommended investments.

Base plans to enable Fault Proofs on the Base Sepolia testnet in mid-July. Earlier this month, Optimism activated Fault Proofs on OP mainnet, although adopting the upgrade must be done by each OP Stack chain independently. Fault proofs introduce permissionless output proposals and permissionless challenges. Permissionless output proposals allow anyone to submit claims about the state of the chain, and permissionless challenges, enable anyone to dispute fraudulent claims. The activation transitions the chain to Stage 1 decentralization. Bridge operators on Base Sepolia will need to adjust their bridging logic to support the changes.

The Ethereum Foundation's mailing list was compromised, as disclosed by Tim Beiko, a core developer and the lead of the All Core Devs (ACD) meetings. The breach appears to have occurred at SendPulse, the email automation service used by the foundation. An attacker managed to send a phishing email from updates@ethereum.org to subscribers, falsely promoting a staking collaboration with Lido. Tim Beiko later confirmed that the foundation has locked down access to the mailing list.
