Usage

Setup

import chain registry info that you need

import { ChainProvider, useChain } from "@interchain-kit/react";
import { keplrWallet } from "@interchain-kit/keplr-extension";
import { ThemeProvider } from "@interchain-ui/react";
import "@interchain-ui/react/styles";

import { chain as junoChain, assetList as junoAssetList } from "@chain-registry/v2/mainnet/juno";
import { chain as osmosisChain,assetList as osmosisAssetList } from "@chain-registry/v2/mainnet/osmosis";
import { chain as cosmoshubChain, assetList as cosmoshubAssetList } from "@chain-registry/v2/mainnet/cosmoshub";

const Show = () => {
  const {address} = useChain('osmosis');
  // will show cosmoshub address from what you selected wallet in modal
  return <div>{address}</div>;
};

function App() {
  return (
    <ThemeProvider>

useChain

//query
const { balance } = await queryClient.balance({

  denom: 'uosmo'
})
console.log(balance)
// { amount: 23423, denom: 'uosmos' }

useChainWallet

import { keplrWallet } from "@interchain-kit/keplr-extension";

const Show = () => {
  const juno = useChainWallet('juno', 'keplr-extension')

export default App;

useCurrentWallet

const wallet = useCurrentWallet()

console.log(wallet) // current connected wallet

useAccount

const account = useAccount('cosmoshub', 'keplr-extension')

console.log(account.address) // cosmoshub address in keplr-extension wallet

useOfflineSigner

const offlineSigner = useOfflineSigner('cosmoshub', 'keplr-extension')

console.log(offlineSigner) // cosmoshub offlineSigner in keplr-extension wallet

Developing

When first cloning the repo:

yarn
# build the prod packages. When devs would like to navigate to the source code, this will only navigate from references to their definitions (.d.ts files) between packages.
yarn build

Or if you want to make your dev process smoother, you can run:

yarn
# build the dev packages with .map files, this enables navigation from references to their source code between packages.
yarn build:dev
