Uniswap Labs introduced Permissioned Pools, a new Uniswap v4 hook standard aimed at supporting cryptocurrencies associated with regulated assets. The proposal seeks to integrate compliance requirements directly into the trading infrastructure, without relying on external checks.
The model introduces a system that validates whether a wallet is authorized before allowing operations such as token swaps or liquidity provision. This process takes place within the pool’s own smart contracts, ensuring that the rules are applied automatically and transparently.
Among the first partners are Superstate, Securitize, and Dowgo, which are already working on implementing the standard. The companies plan to use the framework for tokenized assets such as funds, bonds, and stocks, expanding the reach of these products within the cryptocurrency market.
In this format, issuers maintain full control over the permission list, determining which addresses can interact with the pool. Approved users are able to access trading and settlement directly on-chain, using the Uniswap v4 architecture.
The pools use a contract called the Permissions Adapter to custody the regulated asset. Within the system, a wrapped version of the token is traded, created automatically when the asset enters the pool and removed when it exits. In the end, the user receives the original asset.
Access control checks the permission list on every operation, whether a swap or liquidity addition. It is also possible to define distinct permissions, allowing a wallet to trade without necessarily acting as a liquidity provider.
The infrastructure includes administrative tools that allow issuers to update rules, authorize contracts that interact with the assets, and even pause trading when necessary. In specific cases, it is also possible to unwind liquidity positions.
Another relevant point is that liquidity position NFTs cannot be transferred. This prevents an authorized user from moving their position to a wallet that does not meet the required requirements. Even so, even after losing authorization, the holder can remove their liquidity.
Despite the novelty, Uniswap emphasized that the v4 protocol remains permissionless at its core. Developers are still free to create traditional pools, while issuers of regulated assets can choose the new standard when necessary.
The initiative expands the use of tokenization in the ecosystem, connecting real-world assets to the liquidity of AMMs, with compliance rules controlled directly by the issuers.
