+## Wallet Connection & Multi-Account Support
+
+BridgeWise UI SDK supports connecting multiple wallets (MetaMask, Stellar, etc.) and switching between accounts dynamically. This enables professional dApps to offer secure, flexible wallet management for users.
+
+### Key Hooks
+
+```tsx
+import {
+  useWalletConnections,
+  useActiveAccount,
+  WalletConnector,
+  MultiWalletProvider,
+} from '@bridgewise/ui-components';
+
+// Access all connected wallets and accounts
+const {
+  wallets,
+  connectWallet,
+  disconnectWallet,
+  switchAccount,
+  activeAccount,
+  activeWallet,
+  error,
+} = useWalletConnections();
+
+// Get the current active account and wallet
+const { activeAccount, activeWallet } = useActiveAccount();
+```
+
+### Demo Component
+
+```tsx
+<MultiWalletProvider>
+  <WalletConnector />
+  {/* ...rest of your app... */}
+</MultiWalletProvider>
+```
+
+### Features
+- Connect/disconnect multiple wallets (EVM, Stellar, etc.)
+- Switch between accounts and maintain correct transaction context
+- SSR-safe and production-ready
+- Integrates with network switching, fee estimation, transaction history, and headless mode
+- UI demo component for wallet/account management
+
+### Example Usage
+```tsx
+const { wallets, connectWallet, switchAccount, activeAccount } = useWalletConnections();
+```
+
+### Supported Wallet Types
+- MetaMask
+- WalletConnect
+- Stellar (Freighter, etc.)
+
+### Error Handling
+- Graceful handling of wallet disconnection
+- Structured errors for unsupported wallets
+- Ensures active account is always valid before executing transfers
+
+### Testing
+- Unit tests cover connection, disconnection, account switching, and error handling
