Uniswap v4 now supports permissioned pools that enforce issuer‑managed allowlists, enabling regulated assets to trade on the AMM while keeping the core protocol permissionless.
Uniswap v4 introduces permissioned pools, allowing issuers to enforce allowlists and bring regulated assets onto its automated market maker while preserving the protocol’s core permissionless nature.
What are Permissioned Pools?
Permissioned pools are a new pool type in Uniswap v4 that let token issuers define a whitelist of addresses eligible to trade. This on‑chain allowlist is enforced by the pool’s smart contract, ensuring only approved participants can swap the asset.
How They Work
When creating a permissioned pool, the issuer supplies an allowlist contract that the pool references on each trade. If a trader’s address is not on the list, the swap reverts. The rest of the AMM logic—price curves, liquidity provision, and fee collection—remains unchanged from standard Uniswap pools.
Benefits for Regulated Markets
The feature addresses a key hurdle for institutional and compliant trading: the ability to enforce KYC/AML requirements without sacrificing decentralisation. Issuers can now list security tokens, stablecoins, or other regulated assets while ensuring only vetted participants access the market.

Potential Use Cases
Financial institutions could use permissioned pools for private securities, tokenised real‑estate, or corporate bonds. Likewise, stablecoin issuers can restrict trading to verified participants, reducing regulatory risk.
“Permissioned pools give us the flexibility to bring compliant assets to a decentralized exchange without compromising on security or user experience,” said a Uniswap developer spokesperson.
The rollout is optional; existing pools continue to operate as before, and developers can choose to adopt the new pool type as needed.
