In this recipe we’ll show you how to use the Codex api to create a 3 column launchpad view, complete with filtering, sorting, and realtime updates. This data directly powers the launchpads view on defined.fi. It

The supported launchpads include Pump.fun, Four.meme, Launchlab, Meteora, and more. You can find a complete list of supported launchpads here.

Launchpads

​
Initial Fetch

Start by implementing the following query to fetch the launchpad data, one query for each column.

Now you have the data for the initial render for each column. You can adjust the filters with the remaining of the arguments to the filterTokens query. See the TokenFilters type for more details.

By default filterTokens will return all tokens from a launchpad, across all networks, if you want to scope down to a specific launchpad, use the exchangeAddress filter, if you want to narrow down just to specific network, use the network filter.

​
Realtime Updates

To get realtime updates, you can use the onLaunchpadTokenEventBatch subscription. This gives you every update for each launchpad token.

Now you’ve got all you need to build a fully functional launchpad view.

Launchpad events are extremely high-frequency and will send a large number of requests. We offer a monthly flat-rate option with unlimited requests for this subscription. Contact us for more information.
