Nikita Bier, X's product lead and Solana advisor, previously disclosed that they are developing Smart Cashtags. Some crypto community users questioned the backend for querying crypto assets, stating that some small-cap crypto assets not yet listed on major exchanges might not be searchable, ultimately forcing them to switch to DEXs. In response, Nikita Bier stated that the API (Application Programming Interface) used by the X platform will be able to process almost anything minted on-chain in real time. Furthermore, regarding user inquiries about the future possibility of using self-custodied wallets or even CEX widgets for crypto trading on X, Nikita Bier did not provide a clear answer, only replying with a "following" emoji.
