Polygon released the production-ready version of Plonky3, its latest zero-knowledge (ZK) proving system designed as a modular toolkit for building zkVMs and zkEVMs. Unlike Plonky2, which was optimized for specific hardware and recursion, Plonky3 allows developers to customize the proving system according to their specific needs, such as proof generation speed or proof size. Plonky3 includes components for using various finite fields and hash functions. It offers many proving systems within a single framework. Succinct Labs uses Plonky3 as the proving system for SP1, its general-purpose zkVM capable of proving arbitrary Rust code. Polygon will be using SP1 to generate pessimistic proofs on the Agglayer. Plonky3 is open-source under the MIT and Apache licenses.

Perpetual swaps exchange Polynomial Protocol introduced Polynomial Chain, a new Layer 2 network featuring a native liquidity layer. The chain addresses the challenges of bootstrapping liquidity by enabling new applications to tap into shared liquidity. Polynomial invites developers to build prediction markets, options markets, and structured products on its chain. Polynomial Chain will offer integrated account abstraction, aiming to bridge the gap between DeFi and centralized exchanges by providing enhanced UX. Polynomial also launched a retroactive points program to reward users of its Earn Vaults and Polynomial Trade products. Users can claim their points by making a deposit once the chain goes live.

LI.FI, the DEX and bridge aggregation protocol behind Jumper, experienced an exploit resulting in about $10 million in losses. The attack targeted users who had manually set infinite approvals for the protocol. Peckshield noted that LI.FI had previously suffered the same exploit in March 2022. The vulnerability allows attackers to make arbitrary calls to token contracts, transferring funds from users’ wallets with infinite approvals. LI.FI has since contained the exploit and is working with law enforcement to recover the stolen funds.

Uniswap launched its Uniswap Extension browser-based wallet for all users. Unlike existing browser wallets, the Uniswap Extension integrates directly into the browser's sidebar, enabling users to perform swaps, send, and receive transactions. Key features include MEV protection, automatic network switching, and access to offchain liquidity. Users can track their assets across 11 networks in a unified view.
