# Introduction

> Learn how to get started with the OneBalance Toolkit to begin removing onchain complexity like chains, bridges and gas in your app.

export const LoomVideo = ({loomUrl}) => {
  return <div style={{
    position: 'relative',
    paddingBottom: '56.25%',
    height: 0,
    marginBottom: '1.5rem'
  }}>
      <iframe src={loomUrl} frameBorder="0" webkitallowfullscreen="true" mozallowfullscreen="true" allowFullScreen={true} style={{

};

OneBalance lets you create seamless chain-abstracted experiences with a single API. Instead of integrating with multiple blockchains individually, you can use OneBalance to access tokens across all chains with one simple integration.

This guide uses the Role-Based account configuration. See more on configurations [here](/concepts/accounts).

  <Card title="5 Minutes to First Transaction" icon="bolt">
    Follow our quickstart to make your first chain-abstracted transaction in under 5 minutes
  </Card>

  <Card title="Unified Token Access" icon="coins">
    Access tokens across chains as if they were one token
  </Card>
</CardGroup>

By the end of this quickstart, you'll create a simple application that lets users interact with tokens across multiple chains using OneBalance's chain abstraction capabilities.

  <Step title="Set up your environment">
    Get API keys and configure your project with [Privy](https://www.privy.io) for social login
  </Step>

  <Step title="Create a smart contract account">
    Predict your account address and view aggregated balances across multiple chains in one place
  </Step>

  <Step title="Execute a chain-abstracted swap">
    Swap tokens across chains with no bridging required
  </Step>

  <Step title="Track your transaction">
    Monitor the status of your operations across multiple chains
  </Step>
</Steps>

## Key APIs Used in This Guide

As you follow this guide, you'll interact with several core OneBalance APIs:

* [Predict Account Address](/api-reference/account/predict-address) - Get your smart contract account address before deployment
* [Get Aggregated Balance](/api-reference/balances/aggregated-balance) - View your token balances across all chains
* [Get Quote](/api-reference/quotes/get-quote) - Request quotes for cross-chain swaps or transfers
* [Execute Quote](/api-reference/quotes/execute-quote) - Execute your signed quotes
* [Check Status](/api-reference/status/get-quote-status) - Track your transaction status

<Tip>
  You can learn more about these and other APIs in our [API Reference](/api-reference/introduction).
