Ripple developers, through the RippleX account on X, formerly Twitter, announced that they completed the extensive testing of the XLS-30 AMM. This is a proposed amendment that, if adopted, would bring automated swap, trading, and liquidity provisioning capabilities to XRP Ledger (XRPL). 

Back in July, audit firm CertiK completed the audit of XLS-30 with a successful result of no major issues, however, 35 minor issues did come up, which have since been resolved. AMMs are the underlying protocol that power decentralized exchanges (DEX) that have been in demand by Ripple users for a long time now.
