X to Roll Out Smart Cashtags as Musk Pledges New Open-Source Algorithm Under EU Scrutiny

X’s head of product Nikita Bier said on Sunday that the platform is developing Smart Cashtags, a feature that lets users tie ticker symbols to specific tokens or smart contracts and view real-time price data. The announcement followed backlash over engagement limits, as Elon Musk promised to open-source X’s new recommendation algorithm within seven days while the company faces EU investigations, fines, and growing criticism about bot activity and throttled crypto reach.
