CoW Protocol deployed its MEV-Capturing CoW AMM on Base, protecting liquidity providers from losses due to MEV attacks such as Loss Versus Rebalancing (LVR). LVR is the largest source of MEV, even bigger than frontrunning and sandwich attacks combined. Anyone can deploy pools on Base using the CoW AMM pool creator. The CoW AMM uses batch auctions to auction the right to rebalance the pool at the correct market price, with the amount paid by the winning solver being distributed to the pool's liquidity providers. It ensures that the total value of a pool’s reserves remains balanced. CoW AMM is optimal for pools that trade between non-stable token pairs.

A proposal by the Arbitrum DAO to transition Arbitrum One and Arbitrum Nova to the Arbitrum Bounded Liquidity Delay (BoLD) dispute resolution protocol is now open for voting. BoLD introduces faster and more reliable dispute resolutions, fixed delays for assertion confirmations, enhanced censorship resistance, and improved security. The upgrade will enable interactive fraud proofs and allow permissionless validation on Arbitrum One. The milestone will also secure green status for Arbitrum's State Validation slice on L2Beat’s Risk Rosette framework, signaling progress toward achieving Stage 2 rollup status. Voting for the proposal ends on January 23, 2025.

Ethereum core developers have chosen "Gloas" as the name for the consensus layer upgrade after Fulu. For Ethereum upgrade names, execution layer upgrades are named after Ethereum event host cities, while consensus layer upgrades are named after stars. A version of the two names is then combined for coupled upgrades. Currently, core developers are focused on finalizing devnets for Pecta before moving on to testnet forks. The subsequent upgrade, Fusaka, which combines Fulu and Osaka, is planned after Pecta. EIP-7773 is the Meta EIP assigned for the Gloas/Amsterdam upgrade outlining EIPs for inclusion and the overall fork scope.

Boost, a token incentive distribution platform, has launched Boost V2, introducing features like dynamic rewards, pegged incentives, and budget accounts. The update also extends functionality, allowing users to incentivize nearly any action on any smart contract by specifying a contract address, function, or event signature. With dynamic rewards, creators can offer larger incentives to their most active users. Pegged incentives tie reward amounts to fixed USD or ETH values, reducing exposure to token price volatility.
