Embedded Wallet SDK React

With the Embedded Wallet SDK, you can supercharge your dApp’s UX. It is super easy to integrate and completely customisable to meet your dApp’s styles. It also helps solve the current Snaps limitations and integrating this will allow users to view their balances, manage their assets, and more.

}

Example Configuration

import { Page, Actions } from '@leapwallet/snaps-sdk-react'
const config: Config = {
title: (page) => {
switch (page) {
case Page.HOME:
return "Assets";
case Page.ACTIVITY:
return "Activity";
}
},
closeOnBackdropClick: true,
closeOnEscape: true,
actionListConfig: {
[Actions.Swap]: {

console.log(chainId);
},
enabled: true,
},
[Actions.Bridge]: {
enabled: false,

};

Usage with Custom React UI

In case you want to create your own UI in react, we have exposed the react hooks that we use internally. If you are not using react, then you can check out the next page.
For making queries, we primarily use swr, so a lot of return values from hooks will have the same return type (except for the data).

User Balances

To fetch user balances, you can use useRichBalance hook.
const balanceQuery = useRichBalance(
address,
chainId,
restUrl,
swrConfiguration
);
Parameters -
  1. 1.
    address - the wallet address your querying the balance for
  2. 2.
    chainId - self explanatory
  3. 3.
    restUrl (optional) - custom rest url for the node
  4. 4.
    swrConfiguration (optional) - configure your swr query, click here for more information

User Activity

To fetch user activity, you can use useActivity hook. The return type of a @tanstack/react-query useInfiniteQuery hook.
const activityQuery = useActivity(address, chainId, restUrl);
Parameters -
  1. 1.
    address - the wallet address your querying the balance for
  2. 2.
    chainId - self explanatory
  3. 3.
    restUrl (optional) - custom rest url for the node
Return Value -
The activityQuery.data.pages field will be a list of objects with the following fields -
{
sender: [] // array of activity where user is sender of tokens
recipient: [] // // array of activity where user is received of tokens
}
Usage Example -
Using the activity data
import { type ActivityCardContent } from '@leapwallet/snaps-sdk-core'
// flat list of activity
const activityList = activityQuery.data.pages
.reduce((acc, cur) => {
return [...acc, ...cur.sender.activity, ...cur.recipient.activity];
}, [] as ActivityCardContent[]);
// you can now sort this list however you want
Triggering the next (data) page load using the last element on the list
const [searchQuery, setSearchQuery] = useState<string>('')
useEffect(() => {
// track last item on the list
const lastItem = document.querySelector("#activity-bottom");
if (
!lastItem ||
activityQuery.isLoading ||
activityQuery.isFetchingNextPage ||
activityQuery.error ||
searchQuery.trim().length > 0
) {
return;
}
const handleIntersection = ([i]: IntersectionObserverEntry[]) => {
if (i.isIntersecting) {
activityQuery.fetchNextPage();
}
};
const observer = new IntersectionObserver(handleIntersection, {
root: null,
rootMargin: "0px",
threshold: 1.0,
});
observer.observe(lastItem);
return () => {
observer.disconnect();
};
}, [activityQuery, debouncedSearchQuery]);
