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 across all of Twitter/X in real time — 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 real-time cashtag monitoring via keyword alerts, delivered to Telegram, WebSocket, webhooks, or REST API.

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). eToro reported 4.7 million cashtag searches per day on the platform — that's how much trading activity flows through cashtags.

Why Monitor Cashtags?

How to Monitor Cashtags with Xanguard

Option 1: Keyword Alerts (Track Any Cashtag)

Xanguard's Search Alerts monitors any keyword — including cashtags — across all of Twitter/X. When someone tweets your tracked cashtag, you get an alert.

1. Open @Xanguard_bot on Telegram
2. Enable Search Alerts add-on
3. Add your queries: $SOL, $BTC, $PEPE
4. Receive alerts whenever those cashtags appear in tweets

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:

1. Track the accounts you want to monitor: /add @kol1 @kol2
2. Set keyword filters: /keywords @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": "$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

HMAC-SHA256 signed webhook delivery to your server whenever a matched cashtag appears.

Cashtag Monitoring vs Hashtag Monitoring

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. eToro partnered with X to power this feature, reporting 4.7 million cashtag searches per day.

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.
