Wallet Aggregator - React

A library to help integrate the sdk to a react project.

Usage

The library supplies a WaletContextProvider which will hold information related to the available wallets and selected wallets, as well as the hooks needed to access and configure. While the context holds a "main" or "default" wallet which belongs to a single chain, it allows to keep track of wallets from multiple chains at the same time.

Wrap the application in the WalletContextProvider component. The provider expects a prop wallets which is either a map of Wallet arrays indexed by chain id or a function which builds such map.

Using a map:

import {
  CHAIN_ID_ALGORAND,
  CHAIN_ID_ETH,
  CHAIN_ID_SOME_CHAIN,
} from "@xlabs/wallet-aggregator-core";
import {
  MetamaskWallet,
  WalletConnectWallet,
} from "@xlabs/wallet-aggregator-algorand";
import { SomeWallet } from "@xlabs/wallet-aggregator-some-chain";
import { WalletContextProvider } from "@xlabs/wallet-aggregator-react";

type AvailableWalletsMap = Partial<Record<ChainId, Wallet[]>>;

const Main = () => {
  const wallets: AvailableWalletsMap = {
    [CHAIN_ID_ETH]: [new MetamaskWallet(), new WalletConnectWallet()],
  };

  return (
    <WalletContextProvider wallets={wallets}>
      <App />
    </WalletContextProvider>
  );
};

Using a function:

import {
  CHAIN_ID_ALGORAND,
  CHAIN_ID_ETH,
  CHAIN_ID_SOME_CHAIN,
} from "@xlabs/wallet-aggregator-core";
import {
  MetamaskWallet,
  WalletConnectWallet,
} from "@xlabs/wallet-aggregator-algorand";
import { SomeWallet } from "@xlabs/wallet-aggregator-some-chain";
import { WalletContextProvider } from "@xlabs/wallet-aggregator-react";

type AvailableWalletsMap = Partial<Record<ChainId, Wallet[]>>;

const Main = () => {
  const walletsBuilder = (): Promise<AvailableWalletsMap> => {
    const someChainParams = await fetchSomeChainParams();

    return {
      [CHAIN_ID_ETH]: [new MetamaskWallet(), new WalletConnectWallet()],
      [CHAIN_ID_SOME_CHAIN]: [new SomeWallet(someChainParams)],
    };
  };

  return (
    <WalletContextProvider wallets={walletsBuilder}>
      <App />
    </WalletContextProvider>
  );
};

Hooks

A set of react hooks are supplied. These are:

// Retrieve the current wallet, returns undefined if not set
const wallet: Wallet | undefined = useWallet();

// Retrieve the wallet from a given chain, returns undefined if not set
const walletFromChain: Wallet | undefined = useWalletFromChain(chainId);
// Retrieve all available wallets for a given chain
const walletsForChain = useWalletsForChain(chainId);

// Retrieve all available Wallets
const allWallets: AvailableWalletsMap = useAvailableWallets();

// Retrieve all available chains
const chains: ChainId[] = useAvailableChains();

// Returns a function used to set the current wallet
const changeWallet = useChangeWallet();
const wallet: Wallet = new MyWallet();
changeWallet(wallet);

// Returns a function used to unset the wallet from a given chain
// If the removed wallet is the "default" or "current" wallet, it
// selects the next available wallet to be the new default
const unsetWalletFromChain = useUnsetWalletFromChain();
unsetWalletFromChain(chainId);
