React Native Kin SDK wrapper for the official Android and iOS Kin SDK's

Demo applications

If you want to implement the Kin React Native SDK in your applications, you probably want to start out with the demo application:

Kin SDK React Native Demo

Usage

In this section you can read how to use the Kin React Native SDK in your project.

Step 0: Install dependencies

You need to install the @kin-sdk/react-native package to your project:

yarn add @kin-sdk/react-native
# Or if you are using npm
npm install @kin-sdk/react-native

Step 1: Initializing the Kin Client

The first thing you need to do is import the KinSdk and environment into your project, and set up a reference to the environment:

// Import the client
import { KinEnvironment, KinSdk } from '@kin-sdk/react-native';
// Set up the environment
const env = KinEnvironment.Test;

Step 2: Generate a new key pair

In order to interact with the blockchain you need a key pair that consists of a secret and publicKey.

This account will generally be stored on the users' device. Make sure that the user has a way to export their secret, so they won't lose access to their Kin.

// Create a key pair
const { secret, publicKey } = KinSdk.generateRandomKeyPair();

Step 3: Create an account on Kin blockchain

Use the secret of the account you generated in the previous step to create the account on the blockchain.

Creating the account may take a little while (up to 30 seconds, possibly longer on a busy moment) after the result above has been returned. You can use the getBalances method (see next step) to make sure the account is in fact created. As soon as the account is created correctly, the getBalances method will return the address with the balance.

// Create the account
const [res, err1] = await KinSdk.createNewAccount(env, { secret });

if (err1) {
  // handle error 1
}

Step 4: Get balances

The next step is retrieving the balances. Kin is a token on the Solana blockchain, and your Solana Account can consist of various 'balances' or 'token accounts'. You can read more details here.

// Retrieve balances from account
const [accounts, err2] = await KinSdk.resolveTokenAccounts(env, { publicKey });

if (err2) {
  // handle error 2
}

Step 5: Submit a payment.

After this is done, you are ready to submit a payment.

The memo field here is optional, the other fields are required.

const secret = account.secret;
const tokenAccount = account.publicKey;
const destination = 'Don8L4DTVrUrRAcVTsFoCRqei5Mokde3CV3K9Ut4nAGZ';
const amount = '42';
const memo = 'One Kin as a Donation';
await KinSdk.sendPayment(env, { secret, destination, amount, memo });
