CEX Listing Alerts

A CEX listing alert pings you the second a major centralised exchange publicly announces it’s listing one of your tracked tokens. Unlike price alerts you have to configure with thresholds and directions, listing alerts are a single yes/no toggle per token: you either want the notification or you don’t.

What gets watched

Section titled “What gets watched”

The bot listens to a live feed of exchange-listing announcements from the major centralised exchanges (Binance, Coinbase, OKX, Upbit, Bybit, Kraken, KuCoin, and others). Each announcement is matched against your watchlist by ticker symbol, scoped to the chain the token lives on, and a second cross-check against the on-chain price feed confirms the listing is for the same asset before the alert fires.

How to call it

Section titled “How to call it”
/listings

That’s the whole command. No arguments. Opens a per-page list of every token in the current chat’s watchlist with a green ✅ or grey ⚪ next to each row.

  • Green ✅ — listing alerts are ON for that token.
  • Grey ⚪ — listing alerts are OFF.

Tap any row to flip the toggle. The message edits in place and you stay on the same page — useful when you’re working through a 30-token watchlist.

Scope: DM vs group

Section titled “Scope: DM vs group”
  • In DM — toggles affect your personal watchlist. Alerts arrive in the same private chat with the bot.
  • In a group — toggles affect the group’s watchlist for the current forum topic (or the main chat if forum topics aren’t used). Alerts arrive in that same group, in the same topic.
  • Group toggles are admin-only. Anyone can run /listings to see the current state, but only group admins can change a toggle. Non- admin taps return a quiet “admins only” notice.

What a listing alert looks like

Section titled “What a listing alert looks like”

When a matching announcement fires, the bot posts the raw announcement text from the exchange’s feed, with the matched token’s chain emoji, ticker, and the announcement source URL appended:

📡 New CEX Listing
Binance will list (PEPE) in the Innovation Zone at 2026-05-25 14:00 UTC.
Trading pairs: PEPE/USDT, PEPE/FDUSD

🔹 PEPE
https://www.binance.com/en/support/announcement/abc123

The body is the exchange’s own announcement text verbatim — Prysm doesn’t rewrite or summarise it. The footer adds the chain emoji, ticker, and a tappable link to the original announcement so you can verify the source in one tap.

Defaults and the master switch

Section titled “Defaults and the master switch”

New tokens added to a watchlist have listing alerts on by default. You can flip the global default off (and individual tokens stay toggled to whatever you set them to) from /settings:

  • In DM: /settings → Listing Alerts → toggle.
  • In a group (admin only): /settings → Group → Listing Alerts → toggle.

When the master switch is off, no listing alerts fire for that user or group, regardless of the per-token toggle state. Flipping the master switch back on restores notifications without losing your per-token preferences.

Caveats

Section titled “Caveats”
  • Listings only — not delistings, not partial listings. The feed the bot consumes covers public listing announcements. Delisting notices and “trading suspended” updates are not surfaced.
  • Ticker collisions across chains. Many tokens share the same symbol across chains (every chain has a “PEPE”). The bot uses an on-chain price-feed cross-check before firing an alert — if the announcement is unambiguously for a token whose symbol matches one on your watchlist AND the chain context lines up, you get the alert. Edge cases where two chains list the same symbol on the same day are deduplicated by an in-memory 60-second window.
  • Some announcements arrive late or out of order. Exchanges publish on their own schedules; the bot delivers as fast as the source feed pushes the event. Most major exchanges show up within seconds of the public post.
  • Availability. CEX listing alerts depend on a backend feed connection. If you don’t see /listings produce anything useful, the feature may not be enabled on your deployment — the bot will tell you with a clear notice if that’s the case.
