The automated market-making protocol Yield Basis, founded by Curve founder Michael Egorov, announced the launch of a permissionless propAMM, aiming to upgrade its liquidity mechanism on Curve. This design combines market perception pricing with dynamic fees, aiming to increase trading volume, reduce arbitrage losses, and improve liquidity provider returns. According to its simulations over the past 18 months, Yield Basis's WETH position is projected to grow at an annualized rate of 8.5% in ETH terms under the new design, compared to 3.6% under existing parameters.Officials stated that WETH liquidity providers do not need to take additional actions, as the new design will directly affect their respective liquidity pools. The small transaction fee for pulling the pool price back to the market price is 0.50%, and anyone can submit prices or deposit funds, with the relevant code being open source. The WETH pool will be deployed first, and Bitcoin-related liquidity pools will follow after the successful deployment of the WETH pool.According to the announcement, the liquidity pool will charge based on the profits earned by arbitrageurs from trades, retaining about two-thirds of the profits above the minimum fee. The new design features lower single transaction fees, with simulated trading volumes approaching three times the current levels, requiring donations of about one-quarter of the current amount. The Yield Basis DAO owns the strategy, and the Curve Emergency DAO can shut it down in emergencies, while the Curve liquidity pool contract itself remains unchanged. Curve DAO vote 1508 will connect the strategy to the WETH pool and set the reserved profit ratio, while Yield Basis vote 60 will set the LevAMM fee at 1.5% (currently 1.3%), with the donation rate being about 1.2% of the pool value per year (currently about 5%). The above simulations only include arbitrage exchanges and do not account for regular trading and liquidation.

EthLabs founder Barnabé Monnot (barnabé.eth) released the Week 2 update, summarizing the team's latest progress in the launch and financing phase as well as the direction of ecological discussions. In terms of interoperability (Interop), the team stated that they are enhancing confidence in asynchronous interoperability based on zero-knowledge proofs (zk), believing this will help build safer cross-chain bridges and improve the native distribution capabilities of assets in Ethereum's multi-layer network.Currently, some cross-chain paths still experience delays, especially in the L2 → L1 direction; in this context, the intents mechanism can serve as a transitional solution, while sufficient L1 liquidity also helps match cross-chain executors (solvers). At the same time, the L1 → L2 path is expected to significantly reduce confirmation delays through the Fast Confirmation Rule (FCR), with clients already beginning to integrate this mechanism.In terms of ecological discussions, PropAMMs (Proposal-based AMM) have become a recent focus for multiple teams and researchers, with the core being the potential optimization space between L1 execution efficiency and transaction building (block building). Meanwhile, ENS is emphasized as a key infrastructure for Ethereum, and the team is continuously communicating with relevant stakeholders to advance its development direction. Regarding team building, Ethlabs has currently received over 300 applications, processed about 20%, with a short-term goal of expanding to around 10 people and a mid-term goal of expanding to about 20 people, focusing on recruiting talents with engineering capabilities and domain expertise.In terms of financing, Ethlabs stated that the current financing is nearing completion and has received early support from BitMNR, Sharplink, and Ethereum Joseph, planning to bring in 1-2 core investors before entering the next phase.

The on-chain spot exchange Rialto has announced its departure from stealth mode and is officially live. The platform is powered by PropAMM (proprietary automated market maker) and focuses on the integration of cryptocurrency and traditional finance, having collaborated closely with Robinhood Crypto, Offchain Labs, and Arbitrum over the past year.It is reported that Rialto is built on top of Robinhood Chain and Arbitrum, breaking the traditional market time constraints and supporting 24/7 trading of cryptocurrency spot, stock tokens, ETFs, commodities, and Pre-IPO assets. Users can self-custody equity tokens and use them directly as collateral for third-party lending. Currently, the platform is running its own PropAMM "Rivo Altus" to provide foundational liquidity, with over 90 Robinhood tokenized stocks and mainstream crypto assets already launched in the initial phase.
