According to X platform product lead Nikita Bier’s X post on May 8, the platform has upgraded its Cashtag feature (now called Smart Cashtags), allowing users to directly embed real-time price chart widgets in their posts and integrate buy and sell action buttons. Per the same announcement, the API supporting Smart Cashtags can process in real time any asset issued on blockchain networks.
Smart Cashtags Core Feature Specifications
Based on Nikita Bier’s official announcement and the platform’s early interface mockups, Smart Cashtags’ upgraded capabilities include:
Real-time price chart embedding: By clicking the Cashtag label in the post, the real-time price chart for the corresponding asset is displayed directly
Buy/sell button integration: The interface mockup shows buy and sell action buttons integrated directly alongside the real-time price chart for the selected asset
Related post aggregation: After clicking the label, related discussion posts on the X platform are displayed in sync
Full coverage of on-chain assets: The API supports assets issued by any blockchain network, enabling small-cap tokens that are not listed to be shown alongside traditional stocks in the same place
According to Bier’s remarks, when publishing crypto or stock tickers, users can specify a specific asset name or a smart contract address.
Cashtag Feature Evolution Timeline
According to the X platform announcement, the Smart Cashtags upgrade builds on earlier functionality: in early 2026, X rolled out iPhone Cashtags in the United States and Canada, providing users with real-time financial data feeds; after that, it expanded to the web version so users can access real-time charts and asset information on desktop; in April 2026, Bier posted on X to hint that it is pushing forward crypto-related products. Nikita Bier is the founder of Gas App (now acquired by Discord) and currently serves as X’s product lead.
X Money Plan: Background on the P2P Payment Wallet
According to X platform’s public statement, the Smart Cashtags upgrade is part of X’s broader expansion plan for financial services. Former CEO Linda Yaccarino announced in January 2025 that X Money is being launched in partnership with Visa, positioned as a peer-to-peer (P2P) payments digital wallet.
According to Elon Musk’s public remarks in early March 2026 at an xAI talk, X Money has completed internal employee testing and plans to open the test to a limited number of external users within one to two months. Musk also disclosed that X holds remittance licenses in more than 40 states in the U.S., but has withdrawn its application in New York State; X’s monthly active users are about 600 million.
