CEX Listing Alerts

When a centralised exchange announces it’s listing a token you watch, Prysm sends you the announcement. You also hear when an exchange announces a delisting, so you can act before trading stops.

There’s nothing to set up. Every token on your watchlist has listing alerts on from the moment you add it.

How tokens are matched

Announcements name a token by its ticker, not its contract. Prysm matches the ticker against the tokens you watch, on every chain.

Tickers can collide

Many tokens share a ticker. If you watch a small PEPE on Base and an exchange lists a different PEPE, you’ll still get the alert. Every alert reminds you of this, and shows the market cap of your token so you can tell at a glance whether it’s the same one. Always open the announcement before acting.

Choose tokens with /listings

Send /listings to see your watchlist, one button per token:

[🔔 🔷 PEPE: ON]
[📡 🟣 BONK: OFF]
[🔔 🔵 BRETT: ON]

• 🔔 … ON: listing alerts are on for that token.
• 📡 … OFF: they’re off.

Tap a button to flip it. The list edits in place and stays on the same page, 10 tokens per page. The top of the message also shows the master switch (see below), so you know whether anything will fire at all.

The master switch

/settings → Alerts → CEX Listing Alerts turns listing alerts on or off for the whole chat. When it’s off, nothing fires, whatever /listings says. Your per-token choices are kept, so switching it back on restores them.

In a group

• /listings in a group shows the group’s watchlist for the current forum topic, and alerts arrive in that topic.
• Anyone can look. Only group admins can flip a token or change the settings.
• In /settings → Alerts → CEX Listing Alerts, admins can also pick what gets matched:
  • Watchlist (default): only tokens on the group’s watchlist.
  • All Pasted: the watchlist plus every token pasted in the group within a look-back window of 30d, 3m, 6m, 12m or All time. The alert goes to the topic where the token was last pasted.

A shorter window means fewer ticker collisions from old pastes. The group gets one alert per announcement, however many times the token was pasted.

What an alert looks like

🔔 CEX Listing Alert

Binance Will List Pepe (PEPE)
View announcement

Your watched token: PEPE (Pepe) on Ethereum
Market Cap: $4.21B

⚠️ Ticker symbols can collide across tokens. Verify the announcement matches your PEPE before acting.

• The header is 🔔 CEX Listing Alert for listings and ⚠️ CEX Delisting Alert for delistings.
• The next line is the exchange’s own announcement text, followed by a View announcement link to the source.
• The token line names your token and its chain. For a match from the group’s paste history it reads “Token pasted in this group” instead.
• The market cap line is left out when it isn’t available.
