TLDR
Xs upcoming Smart Cashtags will let you tag specific crypto assets and smart contracts; examples shown include Bitcoin (BTC), Bonk (BONK), and Base, with broader on-chain coverage planned per previews in the announcement (crypto coverage examples).
- Scope: the API is described as almost real-time for anything minted on chain, implying wide token coverage beyond large caps (statement and rollout timing).
- Solana tokens are explicitly highlighted and will surface charts and related posts inside X (Solanas post).
- Screens also show traditional tickers (for example BRK.B) alongside crypto, but no formal whitelist has been published yet (feature preview details).
Deep Dive
1. Coverage Examples
Early screenshots and media summaries show crypto choices like Bitcoin (BTC), Bonk (BONK), and Base among suggested assets when typing $ to tag a post. These previews indicate asset-specific pages with live prices and discussion rollups rather than a static search result (examples in feature coverage).
There is not yet a published whitelist. The intent is asset-aware tagging that disambiguates similar tickers and links directly to the exact asset or contract, reducing confusion for tokens with overlapping names (preview details).
expect common coins to be supported out of the gate, with fast follow-on for additional tokens as coverage expands.
2. On-Chain Priority
Xs head of product emphasized near real-time coverage for anything minted on chain, suggesting support will extend well beyond major coins to smaller caps and newly launched DeFi tokens that traditional data feeds often miss (API and scope description).
That design would enable cashtags to pull live price context and aggregate conversation for precise assets, including specific smart contracts, which is particularly useful in ecosystems with many lookalike tickers.
discovery and verification could become faster inside X. If you rely on social catalysts, cashtags can anchor posts to the exact token you mean and show price context without leaving the app.
3. Solana Call-Out and Timing
Solanas official account highlighted that Smart Cashtags will allow posting Solana tokens with charts and related news directly within X, reinforcing that L1/L2 network tokens are in scope (Solana post).
Media reports cite a feedback phase now and a targeted public release next month, aligning with the preview status and iterative rollout plan (rollout timing).
if you follow Solana narratives (for example BONK or other SPL tokens), expect native support early, with broader networks likely to follow as integration expands.
Conclusion
No official master list is published yet. Based on previews, initial support includes major coins and highlighted tokens like BTC, BONK, and Base, plus Solana tokens, with a plan to cover anything minted on chain as Smart Cashtags roll out. Practically, this points to broad token support over time, starting with widely referenced assets and expanding as X finalizes the feature and gathers feedback.
