Filter large Pump trades before sending an alert

Combine a mint filter, trade side, quote-asset threshold, and an excluded wallet before notifying Telegram.

Before you begin#

  • Choose Solana mainnet and a working RPC route in runtime settings. These examples read live data; illustrative results below will differ.
  • Create and select your bot using Telegram setup, then set chatId in Globals. Keep bot tokens in the connection.
  • Set mintAddress, quoteMint, minimumQuoteAmount, and watchedSide. excludedWallet can be your public wallet address, or * to exclude none.

Walk through the workflow#

  1. Watch trades listens for the selected mint’s bonding-curve trades.
  2. Code converts the displayed quote quantity to a number for the threshold comparison. It also checks the quote mint, trade side, and excluded wallet.
  3. If forwards only matching trades. Telegram reports the observed trade, including its signature; this graph places no order.
  4. Try a threshold above and below an observed amount to understand why a trade passes or fails.

Check the rule with sample values#

For a threshold of 10 quote tokens, a matching buy of 12 passes. A buy of 8, a sell of 12, a trade in another quote asset, or a trade by excludedWallet fails. These numbers explain the condition; choose your own threshold.

Why the quote mint matters#

An amount of 10 in one asset is not comparable to 10 in another. The filter checks identity before sending the result. Raw on-chain quantities stay strings; Number is used only for the display-amount threshold.

Extend the workflow#

The reviewed trade example shows how to use an observed mint and signature in a separate one-run order. A PumpSwap pool needs its own watcher after graduation; this listener covers the bonding curve.

If it does not match#

Inspect Code’s matches value and the original event. Set Timeout to 0 only after your filter works. Notifications can be repeated if a source redelivers an event; this example does not claim exactly-once delivery.
