Raydium, one of the largest automated market makers on Solana, has introduced a permissioned AMM designed for compliant asset trading, adding an access-controlled venue alongside its existing public liquidity pools. A permissioned AMM is an automated market maker in which participation is gated: rather than allowing any wallet to trade or provide liquidity, the pool applies access controls that restrict who can interact with it. Raydium detailed the launch through its official channel on X, framing the product as infrastructure for assets that require controlled market access on Solana.
