+## Wallet Integration
+
+This guide explains how to integrate wallets with the Babylon staking dApp. The dApp supports both Bitcoin (BTC) and Babylon (BBN) wallets through a unified interface.
+
+### Supported Wallet Types
+
+#### Bitcoin (BTC) Wallets
+
+Both native and injectable wallets require implementing `IBTCProvider` interface
+
+1. Native Wallets
+
+- Must submit a PR to add the implementation
+- Examples: `OKX` and `OneKey` Chrome Extensions, `Keystone` Hardware Wallet
+
+2. Injectable Wallets
+
+- No PR required
+- Must inject implementation into `window.btcwallet`
+- Common in mobile wallet browsers
+
+#### Babylon (BBN) Wallets
+
+Both native and injectable wallets require implementing `IBBNProvider` interface
+
+1. Native Wallets
+
+- Must submit a PR to add the implementation
+- Example: `Keplr`
+
+2. Injectable Wallets
+
+- No PR required
+- Must inject implementation into `window.bbnwallet`
+- Common in mobile wallet browsers
+
+### Integration Process
+
+#### 1. Implement Provider Interface
+
+Choose the appropriate interface based on your wallet type:
+
+```ts
+// For BTC wallets
+interface IBTCProvider {
+  connectWallet(): Promise<void>;
+  getAddress(): Promise<string>;
+  getPublicKeyHex(): Promise<string>;
+  signPsbt(psbtHex: string): Promise<string>;
+  signPsbts(psbtsHexes: string[]): Promise<string[]>;
+  getNetwork(): Promise<Network>;
+  signMessage(message: string, type: "ecdsa"): Promise<string>;
+  getInscriptions(): Promise<InscriptionIdentifier[]>;
+  on(eventName: string, callBack: () => void): void;
+  off(eventName: string, callBack: () => void): void;
+  getWalletProviderName(): Promise<string>;
+  getWalletProviderIcon(): Promise<string>;
+}
+
+// For BBN wallets
+interface IBBNProvider {
+  connectWallet(): Promise<void>;
+  getAddress(): Promise<string>;
+  getPublicKeyHex(): Promise<string>;
+  getOfflineSigner(): Promise<OfflineAminoSigner & OfflineDirectSigner>;
+  getWalletProviderName(): Promise<string>;
+  getWalletProviderIcon(): Promise<string>;
+}
+```
+
+#### 2. Integration Method
+
+For Native Wallets:
+
+1. Create wallet provider implementation
+2. Create wallet metadata file
+3. Submit PR to add your wallet
+
+Example metadata for BTC wallet:
+
+```ts
+const metadata: WalletMetadata<IBTCProvider, BTCConfig> = {
+  id: "wallet-id",
+  name: WALLET_PROVIDER_NAME,
+  icon: logo,
+  docs: "https://docs.example.com",
+  wallet: "window-key", // Global window key to detect wallet
+  createProvider: (wallet, config) => new WalletProvider(wallet, config),
+  networks: [Network.MAINNET, Network.SIGNET], // Supported networks
+};
+```
+
+For Injectable Wallets:
+
+1. Implement provider interface
+2. Inject into `window` before loading dApp:
+
+```ts
+// For BTC wallets
+window.btcwallet = new BTCWalletImplementation();
+
+// For BBN wallets
+window.bbnwallet = new BBNWalletImplementation();
+```
+
+### Integration Through Tomo Connect SDK Lite
+
+In addition to direct integration, wallets can also be integrated through [Tomo Connect SDK Lite](https://docs.tomo.inc/tomo-sdk/tomo-connect-sdk-lite).
