#### Likely Key Features:

* **🔐 Multi-Chain Authentication**: Support for Ethereum, Solana, Bitcoin, and other major blockchains
* **⚛️ React Integration**: Complete React components, hooks, and providers for seamless frontend integration
* **🔧 Multiple Signers Support**: Integration with popular wallet libraries (Viem, Ethers.js, Web3.js)
* **🌐 Universal Compatibility**: Works across different blockchain ecosystems from a single SDK

#### Probable Capabilities:

* **Wallet Connection Management** across multiple chains
* **Authentication State Management** with React providers
* **Signer Abstraction** supporting different wallet connection libraries
* **Session Management** and user authentication flows
* **Multi-Chain User Identity** handling

The EmblemAuth SDK **unifies the complex landscape of multi-chain wallet authentication** into a single, developer-friendly interface. Instead of integrating separate authentication systems for each blockchain, developers can use one SDK to handle wallet connections across Ethereum, Solana, Bitcoin, and other networks.
