## Features

-   🌐 Multi-chain support:
    -   Selendra Network
    -   Polkadot Ecosystem
    -   Ethereum EVM Chains
-   💼 Unified wallet interface
-   💰 Token management (ERC-20, native tokens)
-   🔐 Secure account management
-   📊 Real-time balance queries
-   🔄 Network switching capabilities
-   📝 Message signing
-   🔍 Transaction history

## Installation

```bash
# Using npm
npm install bitriel-wallet-sdk

# Using yarn
yarn add bitriel-wallet-sdk

# Using pnpm
pnpm add bitriel-wallet-sdk
```

## Quick Start

```typescript
import { BitrielWalletSDK } from "bitriel-wallet-sdk";

// Initialize the SDK
const sdk = new BitrielWalletSDK();

// Get supported networks
const networks = sdk.getSupportedNetworks();

// Connect to a network (e.g., Selendra Mainnet)
await sdk.connect("selendra");

// Get wallet state
const walletState = await sdk.getWalletState();

// Send a transaction
const txHash = await sdk.sendTransaction({
    to: "0x...",
    value: "1000000000000000000", // 1 SEL
});

// Sign a message
const signature = await sdk.signMessage("Hello, World!");

// Disconnect
await sdk.disconnect();
```

### BitrielWalletSDK

#### Constructor

```typescript
new BitrielWalletSDK(options?: SDKOptions)
```

#### Methods

##### Connection Management

-   `connect(networkId: string): Promise<void>`

    -   Connects to the specified network
    -   Throws an error if the network is not supported
    -   Returns a promise that resolves when connected

-   `disconnect(): Promise<void>`
    -   Disconnects from the current network
    -   Cleans up resources and connections

##### Wallet Operations

-   `getWalletState(): Promise<WalletState>`

    -   Returns the current wallet state including:
        -   Address
        -   Network
        -   Balances (native and tokens)
        -   Connection status

-   `sendTransaction(tx: TransactionRequest): Promise<string>`

    -   Sends a transaction and returns the transaction hash
    -   Supports both EVM and Polkadot transaction formats
    -   Handles gas estimation and fee calculation

-   `signMessage(message: string): Promise<string>`
    -   Signs a message using the current account
    -   Returns the signature in the appropriate format for the network

##### Network Management

-   `getSupportedNetworks(): NetworkConfig[]`

    -   Returns a list of all supported networks
    -   Includes network details and configuration

-   `getCurrentNetwork(): NetworkConfig | null`
    -   Returns the currently connected network
    -   Returns null if not connected

##### Token Operations

-   `getTokenBalance(tokenAddress: string): Promise<string>`

    -   Returns the balance of a specific token
    -   Supports both ERC-20 and native tokens

-   `getTokenInfo(tokenAddress: string): Promise<TokenInfo>`
    -   Returns detailed information about a token
    -   Includes decimals, symbol, and name
