Twitter/X Cashtag Monitoring: Track $SOL & $BTC

When $SOL starts trending on Twitter/X, markets move. When a KOL tweets a cashtag for a new token, early buyers profit. Cashtag monitoring — tracking mentions of $BTC, $ETH, $SOL, and any token ticker from the accounts you follow or across all of Twitter/X — is one of the most direct trading signals available.

Yet there's no dedicated cashtag monitoring tool for crypto traders. Generic hashtag analytics tools like Tweet Binder and Postel track cashtags, but they're built for brand marketing — not for real-time trading alerts. And Twitter/X's new Smart Cashtags feature (launched February 2026) displays live prices but doesn't offer monitoring or alerts.

Xanguard fills this gap with cashtag monitoring delivered to Telegram, WebSocket or REST API (plus signed webhooks for tracked accounts on paid plans): real time for the accounts you track, and on a schedule for search across all of X.

What Is a Cashtag?

A cashtag is a dollar sign followed by a ticker symbol: $BTC, $SOL, $PEPE. Twitter/X treats cashtags as clickable links that show stock and crypto price data (via the Smart Cashtags feature rolled out in February 2026).

Why Monitor Cashtags?

Cashtag Signals for Traders

  • KOL calls: When a top trader tweets $TOKEN, the market moves in seconds
  • Narrative shifts: Sudden spike in $AI or $RWA mentions signals rotating capital
  • New token discovery: First mentions of a new $TICKER = early signal before it trends
  • Sentiment shifts: Volume of $SOL mentions correlates with price action

How to Monitor Cashtags with Xanguard

Option 1: Search Alerts (Track Any Cashtag Across X)

Xanguard's Search Alerts monitors any keyword — including cashtags — across all of Twitter/X. It checks for new matching tweets as often as every minute (you choose: 1 min to 6 h), 30 minutes by default, so it is not real time, but it catches the cashtag no matter who posts it. $50/month for 20 queries.

  1. Open @Xanguard_bot on Telegram
  2. Send /start, open Add-ons and buy Search Alerts
  3. Add your queries: $SOL, $BTC, $PEPE
  4. Receive alerts for new tweets containing those cashtags at each check

Option 2: Per-Account Keyword Filters (Track Cashtags from Specific KOLs)

If you only care about cashtags from specific accounts (not all of Twitter/X), use per-account keyword filters. These are free and real time: on paid plans, new tweets are detected in a median of about 270 ms (see the speed page).

  1. Track the accounts you want to monitor: /add kol1 kol2
  2. Set keyword filters in /settings under Keywords, or in one step: /add kol1 | $SOL, $BTC, $PEPE
  3. You'll only get alerts when those specific accounts tweet those specific cashtags

Option 3: Contract Address Detection (Automatic)

Xanguard automatically detects Solana and Ethereum contract addresses in tweets — no keyword setup needed. When a tracked account tweets a CA, it's highlighted in the alert. Enable "Contracts Only" mode in settings to receive only tweets containing contract addresses.

Cashtag Monitoring via API

For developers building trading bots or dashboards, Xanguard offers full API access to cashtag monitoring:

REST API

# Add a cashtag search query
curl -X POST https://api.xanguard.tech/v1/sa/queries \
  -H "Authorization: Bearer sa_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query_text": "$SOL"}'

# List active queries
curl https://api.xanguard.tech/v1/sa/queries \
  -H "Authorization: Bearer sa_YOUR_KEY"

WebSocket

wss://api.xanguard.tech/v1/sa/ws?api_key=sa_YOUR_KEY

Webhooks

Search Alerts does not send webhooks. For cashtags from accounts you track, paid Tweet Alerts plans can POST each matching tweet to your server, signed with HMAC-SHA256 in the X-Signature header.

Cashtag Monitoring vs Hashtag Monitoring

Trading relevanceVery high — "$PEPE" usually means someone is trading itMedium — "#crypto" could be anything

For crypto traders, cashtag monitoring is strictly more valuable than hashtag monitoring. A tweet mentioning $SOL is almost always about Solana the asset. A tweet mentioning #Solana could be about the ecosystem, the tech, or a conference.

X Smart Cashtags (February 2026)

In February 2026, X rolled out Smart Cashtags — clicking a cashtag now shows live price data, charts, and trading links directly in the app.

Smart Cashtags make cashtags more visible and clickable, which means more people are using them — and more trading signals are flowing through them. But Smart Cashtags don't offer monitoring or alerts. They're a display feature, not a notification feature. That's where Xanguard comes in.

Frequently Asked Questions

How do I monitor cashtag mentions like $SOL or $BTC on Twitter/X?

Two ways with Xanguard. Add $SOL, $BTC, $ETH or any ticker as a keyword filter on the accounts you track, and you get their matching tweets in real time. To catch a cashtag from anyone on X, add it as a Search Alerts query ($50/month for 20 queries), which checks as often as every minute (you choose: 1 min to 6 h). It is not real time.

Why are cashtag mentions on Twitter/X important for trading?

When KOLs tweet cashtags, markets often move within seconds. Cashtag volume spikes also signal narrative shifts and rotating capital, which makes cashtags a major trading signal source.

What is a Twitter/X cashtag?

A cashtag is a dollar sign followed by a ticker symbol, like $BTC or $SOL. Twitter/X treats them as clickable links that display live price data via Smart Cashtags, launched February 2026.

Can I get cashtag alerts via API or webhook?

Yes. Search Alerts matches are available over WebSocket and REST as well as Telegram. For cashtags from accounts you track, paid Tweet Alerts plans can also POST each matching tweet to an HMAC-signed webhook. This makes it suitable for both manual traders and automated trading bots that need programmatic access to cashtag signals.
