## Content

Uniswap Labs shipped two new v4 hooks, one solving a core capital efficiency problem for market makers and one opening AMM liquidity to regulated asset issuers. DualPool, built in collaboration with Spark Protocol, keeps a pool's capital parked in ERC-4626 yield vaults between trades and pulls exactly what's needed into concentrated liquidity the moment a swap arrives. The full withdraw, deploy, execute, re-vault cycle happens atomically inside the swap transaction with no keepers required. DualPool allows market makers to earn on both swap fees and lending yield on idle inventory. Spark will run DualPool's largest deployment, seeded with the $150M in liquidity that they already moved to Aave v4 in June. The Permissioned Pools v4 hook enforces allowlists at the protocol level, where every swap and every LP mint gets checked against an issuer-managed allowlist before settling. The solution is designed for regulated asset issuers such as Superstate and Securitize. The Uniswap protocol stays fully permissionless while issuers get a standardized path to deploy compliant pools on top.
