Merlin is working with Particle Network to provide a simple mechanism to use Merlin Chain via native Bitcoin wallets through BTC Connect. If you want your dApp to support Bitcoin users natively, either continue reading this document or visit P[article Network's BTC Connection Documentation](https://developers.particle.network/landing/introduction).

**High-Level Overview of BTC Connect**

BTC Connect refers to a technology built by Particle Network, allowing Bitcoin users to connect with (EVM-compatible) applications on Merlin Chain through Bitcoin native wallets, such as UniSat, OKX, Bitget and so on.In short, BTC Connect offers a simple, easy-to-integrate SDK that facilitates native Bitcoin wallet connection and interactions. Since native Bitcoin accounts are incompatible with EVM environments, BTC Connect generates and deploys a smart account on Merlin Chain, signed and authenticated by the user's Bitcoin wallet.Beyond the benefit of allowing a path for native Bitcoin accounts to interact with your application, BTC Connect leverages ERC-4337 account abstraction (hence the utilization of a smart account). This allows you to sponsor the gas fees users leveraging BTC Connect, execute batched transactions, etc.An overview of this dynamic between a user's native Bitcoin account and their associated smart account deployed on Merlin Chain can be found below:
