X’s former product chief, Nikita Bier, used a seemingly sarcastic reply on August 25 to confirm a long-teased next step for the platform’s crypto tools: buy and sell controls attached to posts. The remark came after a trader joked that a bull market could begin now that Bier was no longer “shadow banning” Crypto Twitter.
Bier dismissed that framing and pointed to work he says he shipped instead.
He said he created Cashtags, the feature that lets users drop Solana and Ethereum price charts straight into posts.
Those charts already turn a ticker mention into a small market card inside the feed. The new piece, he wrote, is trade buttons “coming soon.”
In the same reply he noted that users can paste contract addresses for freshly minted tokens, so a post can identify a specific coin rather than a reused ticker name.
That combination is the core of the update.
Discovery already happens on X. A chart in the timeline shortens the path from conversation to price.
A trade button would try to remove the last hop: leaving the app for an exchange or wallet.
What are you talking about?
I literally built Cashtags, allowing people to add Solana and Ethereum charts directly into posts—with trade buttons coming soon.
You can even paste contract addresses for newly minted tokens.
There wasn’t a single feature on X for crypto traders…

If it works as implied, a reader could see a token discussed, inspect a chart, and place an order without changing screens.
Bier also made a broader claim about the product history.
Before he joined, he said, X had no dedicated features for crypto traders.
Cashtags, address lookup, and the promised buttons are his answer to that gap.
The post does not name a launch date, list supported assets beyond the Solana and Ethereum chart context, or say who would execute the trades.That last point still matters.
Earlier this year, similar language about trading from the timeline was later narrowed: X would build market data and links, not act as a broker.
Tuesday’s reply does not repeat that correction, and it also does not cancel it.
A button that hands an order to an outside venue is one product. A button that settles inside X is another.
Until the company publishes details, “coming soon” describes intent, not a live checkout.
The setting of the comment is as important as the feature list.
Bier is no longer running product day to day; he left that role in early August and now advises the company.
The person who actually ships the buttons is therefore not the person who announced them.
There is also no statement from X’s official accounts.
The confirmation sits in a personal reply with hundreds of thousands of views, not in a product blog post.
Security questions followed immediately in the thread. Compromised accounts are common on the platform.
A one-tap trade control next to a viral chart would raise the payoff for impersonation and stolen sessions.
Contract address support helps distinguish lookalike tokens, but it does not, by itself, stop a hijacked account from approving a bad trade.
Bier rejected the idea that his departure, or any change in how crypto accounts are ranked, explains the market.
He said the rally is starting because the US Treasury announced it is buying back bonds and weakening the dollar.
In that telling, policy is the catalyst; X is only adding rails.
The practical test is still ahead. Charts and address paste are already in the product. Trade buttons are not. If they arrive, every cashtag post becomes a possible point of sale. If they slip again, this will be another public promise that stopped at the chart.
