Injected

Prompt users to connect to your app with an "injected" wallet, i.e. one that uses window.ethereum to connect to the blockchain; including MetaMask and Coinbase Wallet.

Usage​

import { InjectedWallet } from "@thirdweb-dev/wallets";

const wallet = new InjectedWallet({});

wallet.connect();

Configuration​

Optionally, provide a configuration object when instantiating the InjectedWallet class.

chains

Provide an array of chains you want to support.

Must be an array of Chain objects, from the @thirdweb-dev/chains package.

Defaults to our default chains.

import { InjectedWallet } from "@thirdweb-dev/wallets";
import { Ethereum } from "@thirdweb-dev/chains";

const walletWithOptions = new InjectedWallet(
  {
    chains: [Ethereum],
  },
);
dappMetadata

Information about your app that the wallet will display when your app tries to connect to it.

Must be an object containing name, url, description and logoUrl properties.

import { InjectedWallet } from "@thirdweb-dev/wallets";

const walletWithOptions = new InjectedWallet({
  dappMetadata: {
    name: "thirdweb powered dApp",
    url: "https://thirdweb.com",
    description: "thirdweb powered dApp",
    logoUrl: "https://thirdweb.com/favicon.ico",
  },
});
walletStorage

Some wallets need to store data in persistent storage. This is the storage that will be used for that.

Must be an object conforming to the AsyncStorage interface:

export interface AsyncStorage {
  getItem(key: string): Promise<string | null>;
  setItem(key: string, value: string): Promise<void>;
  removeItem(key: string): Promise<void>;
}

Example:

import { InjectedWallet } from "@thirdweb-dev/wallets";

const walletWithOptions = new InjectedWallet(
  {
    walletStorage: {
      getItem: (key) => {
        // Implement your own storage logic here
      },
      removeItem: (key) => {
        // Implement your own storage logic here
      },
      setItem: (key, value) => {
        // Implement your own storage logic here
      },
    },
  },
);
walletId

An ID for the wallet used to store the wallet in the walletStorage.

import { InjectedWallet } from "@thirdweb-dev/wallets";

const walletWithOptions = new InjectedWallet(
  {
    walletId: "wallet-id",
  },
);

Methods​

Once instantiated, utilize the following methods to interact with the Wallet.

{
  address: string;
  chainId: number;
}
connect​

{
  address: string;
  chainId: number;
}
disconnect​

User disconnects their wallet from your app.

No data is available.

error​

An error occurs in the wallet.

Data available:

{
  cause: unknown;
  message: string;

data is a string | undefined.

request​

Wallet receives some request that the consumer should be notified of. The kind of request is identified by the type field.
