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.

Frission, a top delegate in the Arbitrum ecosystem, introduced a proposal to implement ARB token staking. The proposal seeks to allocate 50% of future surplus sequencer fees to reward ARB token holders who stake and actively delegate their tokens. Frission noted that the growing pool of sequencer fees in the DAO's treasury makes it a target for potential governance attacks. Staking enhances the economic security of the Arbitrum DAO by preventing malicious actors from acquiring significant voting power amid declining ARB prices. The proposal also mentions Tally’s liquid staking token system for preserving liquidity. At current prices, the program is projected to offer around 7% APY for stakers. A preliminary temp check vote for the staking program will go live on Snapshot next month.
Six asset issuers, including BlackRock, Invesco, VanEck, Franklin Templeton, Grayscale Investments, and 21Shares, have submitted their amended Spot ETH ETF S-1 forms. The amendments primarily focus on information about their ETF fees. VanEck will have a fee of 20 basis points, while Franklin Templeton’s will be at 19 basis points, creating a competitive environment. In total, eight issuers, including Bitwise and Fidelity, are now awaiting feedback from the SEC regarding any further modifications. Approval of the Form S-1 filings is necessary before Spot ETH ETF trading can begin. Bloomberg analyst Eric Balchunas anticipates that trading for the ETFs will start by Tuesday, July 2nd.
Talent Protocol launched TALENT, the native token for its onchain reputation platform. Alongside the token, Talent is hosting the Summer of $TALENT, which includes a series of online and offline community-building events. TALENT has a total supply of 600 million tokens. 10 million are allocated for an initial airdrop, expected to launch in July. Another 20 million are available for the Community Round, where participants can buy their share. Eligible users will need to complete a proof-of-humanity KYC process to claim their tokens. Talent Protocol aggregates social graphs from both web2 and web3, enabling users to create a Talent Passport serving as their builder resume.
