Uniswap Launches Permissioned Pools Hook for Tokenized Securities

Uniswap (UNI) has launched the Permissioned Pools Hook, a v4 hook standard that adds compliance checks to its automated market maker. Groma, a venue for tokenized real estate securities, is the first to use it.

The hook lets pool operators control who can trade, which assets can trade, and when trading is open. Swaps and settlement still execute on the base Uniswap protocol.

How the Permissioned Pools Hook Works

Uniswap published a post, Building a Tokenized Securities Venue on Uniswap, describing the design. Pools can enforce access controls and venue rules at the pool level, with conditions such as public fee disclosure, symbol and volume caps, and trading halts. Each venue runs independently, and its operator is responsible for its own legal analysis and compliance.

That structure keeps price discovery and settlement on Uniswap while the venue layer handles the rules that regulated assets require.

The First Venue: Groma

Groma uses the hook for real estate-linked tokenized securities. Access is limited to U.S. accredited investors and users outside the United States, according to reports on the launch. It is the first regulated asset to go live on the AMM under the new standard, and more venues are expected to build on the same hook.

Where Uniswap Fits

Uniswap is a decentralized exchange protocol launched in 2018 by Hayden Adams, according to what Uniswap is on Coinranking. Its v4 hooks let developers attach custom logic to liquidity pools, and UNI holders govern the protocol. The Permissioned Pools Hook extends that system to tokenized stocks, securities and other real world assets, a category where DEX venues have mostly stayed on the sidelines. The Uniswap price chart tracked the launch this week.

The hook is live, and Groma's venue is live. Whether tokenized securities volumes grow on the AMM depends on the venues that adopt the standard next.
