Various hooks for accessing wallet info


A user's wallet lives within the global NodeProvider context, and can be accessed from any child. There are several ways to access a user's wallet, the main way being the hook useWallet
import { useWallet } from '@node-fi/react-native-sdk';
function Component() {
const wallet = useWallet();
// Use the wallet
function useHook() {
const wallet = useWallet();
// Use the wallet


useWalletAddress() will return the address of the currently-active wallet
import { useWalletAddress } from '@node-fi/react-native-wrapper';
function Component() {
const walletAddress = useWalletAddress();
// Use the wallet
function useHook() {
const walletAddress = useWalletAddress();
// Use the wallet


useSetGasToken returns a state variable and a setter for the current default gas currency. Gas currency is persisted across sessions.
The state variable is the address of the current gas token. The updater method takes as argument the address of a gas token. Note that the only check performed is that the provided string is a valid address. If the address of a non-accepted currency is provided, transactions will fail. Future iterations of the SDK will check for valid gas currencies.
import { useSetGasToken } from '@node-fi/react-native-wrapper';
function Component() {
const [currentGasToken, setGasToken]: [string, (s: String) => void] =
return (
<Text>{`Your current gas token is: ${currentGasToken}`}</Text>
<Pressable onPress={() => setGasToken(OTHER_TOKEN)}>
<Text> {`Set gas token to ${OTHER_TOKEN}`} </Text>


This hook will return an array of objects relating to a wallet's balance at a specific point in time. The range for which to fetch balances is a required parameter, and corresponds to the number of days to retrieve data for. A period can be defined by the TimeFrame type from the Core SDK, which has the following construction:
type Time = "hour" | "day" | "week" | "month" | "year";
type TimeFrame = Time | `${number} ${Time}s` | "all";
This means time periods can be specified in number of hours, number of days, number of weeks, number of months, or number of years.
Additionally, the resolution can be supplied as an integer, where the following applies:
5 minutes
15 minutes
30 minutes
1 Hour
1 Day
Five-minute resolution is only available in entirety for up to 1 week in the past.
This hook exposes QueryOptions and FetchDetails as explained in Data Retrieval Hooks
The returned data will be priced according the wallet's default price currency.
usePortfolioHistory(range: DateRange)
import { usePortfolioHistory } from '@node-fi/react-native-sdk';
import { DateRange } from '@node-fi/sdk-core';
function GraphComponent() {
const [dayRange, setDayRange] = useState<DateRange>(1);
const { history: portfolioHistory, fetchDetails } = usePortfolioHistory(`${dayRange} days`);
if (fetchDetails.isFetching) {
// If portfolioHistory === undefined, content is loading
return <LoadingComponent />;
return <Chart data={portolioHistory} x="time" y="total" />;
