Building a Cross-Chain Bitcoin Dapp using the Swing API

In this tutorial, we're going to be demonstrating how you can build a Bitcoin cross-chain dApp capable of bridging assets between the EVM and Bitcoin chains.

This example demonstrates how you can perform a cross-chain transaction between the Bitcoin and Ethereum chains using Swing's Cross-Chain and Platform APIs via Swing's API.

Prerequisites

In this guide, we'll be using an example built with Next.js and Tailwind CSS. If you're not familiar with this stack, don't worry! The example is pre-built, so our focus will be on how to perform a BTC swap in TypeScript using Swing's API. You can follow along with any stack you prefer.

As our dapp is centered around Bitcoin, it's crucial that we integrate a primary wallet that supports the Bitcoin network like xDefi or Trust Wallet.

In our example project, we will be using xDefi's wallet to interact with the Bitcoin network and Thirdweb's SDK to interact with the Ethereum network. With that said, do make sure to install the xDefi wallet extension in your browser.
