Step 1: Install the B3 SDK

1

Install the SDK package

Choose your preferred package manager to install the B3 SDK:
npm install @b3dotfun/sdk
The B3 SDK includes TypeScript definitions out of the box!
2

Import CSS styles

Import the default styles in your application:
import "@b3dotfun/sdk/index.css";

​
Step 2: Add B3Provider

Wrap the B3Provider around your application’s root: 
import { B3Provider, SignInWithB3 } from "@b3dotfun/sdk/global-account/react";

function App() {
  return (
    <B3Provider environment="production" partnerId="your-awesome-partner-id">
      {children}
    </B3Provider>
  );
}

​
Step 3: Use the B3 SDK

Enable global accounts authentication with B3:
import { SignInWithB3 } from "@b3dotfun/sdk/global-account/react";

function App() {
  return (
    <B3Provider environment="production" partnerId="your-awesome-partner-id">
      <SignInWithB3
        provider={{ strategy: "google" }}
        partnerId="your-partner-id"
        onLoginSuccess={(globalAccount) => {
          console.log("Authenticated:", globalAccount);
        }}
      />
    </B3Provider>
  );
}
Enable cross-chain swaps & custom interactions with AnySpend:
import { AnySpend } from "@b3dotfun/sdk/anyspend/react";

function SwapPage() {
  return <AnySpend mode="page" />;
}
