Balancer V3 launches MEV-Cap Hook, a new feature that redirects Maximal Extractable Value (MEV) back to liquidity providers.​ The system works by dynamically adjusting pool fees based on priority fees paid by MEV bots on OP Stack chains like Base and Optimism.​

Key features:

  • Higher priority fees trigger higher dynamic pool fees
  • Captured value stays within the pool
  • Works across all pool types, not just ETH pairs

The mechanism allows MEV bots to operate while ensuring value flows back to LPs instead of leaking out.​ Currently live on Base, with plans to expand MEV protection offerings through collaboration with CoW Protocol.​

Ethena's USDe Launches on Plasma with $28M TVL Pool

**Ethena's USDe stablecoin** has integrated with Plasma's infrastructure through a new USDe/USDT liquidity pool that reached **$28M TVL**. The pool combines three key technologies: - **Stable pool tech** for efficient stablecoin swaps - **Aave boosting** that deploys 100% of liquidity to lending markets - **StableSurge** dynamic fee adjustment **USDe is a synthetic dollar** backed by crypto collateral with delta-hedging strategies, eliminating traditional banking dependencies.
