According to CoinMeta, the developers of XRPL are exploring the possibility of providing exclusive liquidity pools for banks and institutions with KYC. On September 5th, a discussion on the XRPL standard introduced a new concept of a permissioned liquidity pool (AMM), aimed at expanding the existing certificate and permission domain architecture of XRPL to allow banks to provide on-chain liquidity without trading with unverified wallets. This proposal is still in the conceptual stage, has not yet been approved, and has not been activated on the XRP ledger. Its goal is to fill a specific gap in the institutional DeFi infrastructure. The existing permission system DEX can limit order book transactions, allowing only wallets holding approved certificates to participate, but official documentation indicates that permissioned transactions cannot utilize AMM and access to the existing AMM cannot be restricted through permission domains. The proposal suggests attaching the ID domain directly to the AMM pool to determine who can contribute liquidity, participate in governance, and selectively exchange with the pool. It also calls for the establishment of withdrawal exceptions so that liquidity providers can retrieve their assets after the certificates expire.
