Getting Started

Our SDK uses a Provider Pattern, meaning any component within the ThirdwebProvider will have access to the SDK.

Let's take a look at a typical setup.

Specify the network your smart contracts are deployed to in the activeChain prop and wrap your application like so:

import { ThirdwebProvider } from "@thirdweb-dev/react-native";
 
const App = () => {
  return (
    <ThirdwebProvider
      activeChain={"mainnet"}
      clientId={"your-client-id"}
    >
      <AppInner />
    </ThirdwebProvider>
  );
};

Below is an example of where to set this up in your application:

Create React Native App

Finally, we can run our app!

yarn android

yarn ios

import React from "react";
import { SafeAreaView } from "react-native";
import { ConnectWallet } from "@thirdweb-dev/react-native";
 
const AppInner = () => {
  return (
    <SafeAreaView style={styles.backgroundStyle}>
      <ConnectWallet />
    </SafeAreaView>
  );
};

Connect to your smart contract using the useContract hook like so:

import { useContract } from "@thirdweb-dev/react-native";
 
export default function Home() {
  const { contract } = useContract("<CONTRACT_ADDRESS>");
 
  // Now you can use the contract in the rest of the component!
}

You can then use useContractRead and useContractWrite to read data and write transactions to the contract.

You pass the contract object returned from useContract to these hooks as the first parameter and the name of the function (or view/mapping, etc.) on your smart contract as the second parameter. If your function requires parameters, you can pass them as additional arguments.

For example, we can read the name of our contract like so:

import {
  useContract,
  useContractRead,
  useContractWrite,
} from "@thirdweb-dev/react-native";
 
export default function Home() {
  const { contract } = useContract("<CONTRACT_ADDRESS>");
  const { data: name, isLoading: loadingName } = useContractRead(
    contract,
    "name", // The name of the view/mapping/variable on your contract
  );
  const { mutate: setName, isLoading: settingName } =
    useContractWrite(
      contract,
      "setName", // The name of the function on your contract
    );
}

Each extension you implement in your smart contract unlocks new functionality in the SDK.

These hooks make it easy to interact with your smart contracts by implementing the complex logic for you under the hood.

For example, if your smart contract implements ERC721Supply, you unlock the ability to view all NFTs on that contract using the SDK; which fetches all of your NFT metadata and the current owner of each NFT in parallel. In the React SDK, that is available using useNFTs:

import { useContract, useNFTs } from "@thirdweb-dev/react-native";
 
export default function Home() {
  const { contract } = useContract("<CONTRACT_ADDRESS>");
  const { data: nfts, isLoading: isReadingNfts } = useNFTs(contract);
}

If we want to mint an NFT and our contract implements ERC721Mintable, we can use the useMintNFT hook to mint an NFT from the connected wallet; handling all of the logic of uploading and pinning the metadata to IPFS for us behind the scenes.

import {
  useContract,
  useNFTs,
  useMintNFT,
} from "@thirdweb-dev/react-native";
 
export default function Home() {
  const { contract } = useContract("<CONTRACT_ADDRESS>");
  const { data: nfts, isLoading: isReadingNfts } = useNFTs(contract);
  const { mutate: mintNFT, isLoading: isMintingNFT } =
    useMintNFT(contract);
}

The ThirdwebProvider offers a number of configuration options to control the behavior of the React Native and Typescript SDK. We provide defaults for all of them, but you customize them to suit your needs. For more info see the ThirdwebProvider reference.

• We render localWallet as "Continue as Guest" in our ConnectWallet modal.
• When a single supportedWallet is defined, we try to auto-connect to that wallet instead of showing the wallets modal with a single wallet.

You can pass a locale prop to the ThirdwebProvider with the strings in the language of your preference. See the list of strings to translate here.

We support 'en' (English), 'es' (Spanish) and 'ja' (Japanese) out of the box. The default value is 'en'.

import { ThirdwebProvider } from "@thirdweb-dev/react-native";
import React from "react";
 
const App = () => {
  return (
    <ThirdwebProvider locale={"ja"}>
      <AppInner />
    </ThirdwebProvider>
  );
};

You can pass your own strings:

import { ThirdwebProvider, en } from "@thirdweb-dev/react-native";
import React from "react";
 
const App = () => {
  return (
    <ThirdwebProvider
      locale={{
        connect_wallet: {
          label: "Conectar Cartera",
        },
        connect_wallet_details: {
          additional_actions: "Acciones Adicionales",
          // ...
        },
      }}
    >
      <AppInner />
    </ThirdwebProvider>
  );
};

Note that you can also use this prop to replace any string in our UI components.

import { ThirdwebProvider, en } from "@thirdweb-dev/react-native";
import React from "react";
 
const App = () => {
  return (
    <ThirdwebProvider locale={en({
       ... // you can overwrite any string!
    })}>
      <AppInner />
    </ThirdwebProvider>
  );
};
