+
+```
+import { AdenaSDK, WalletProvider } from '@adena-wallet/sdk';
+
+const walletProvider = new WalletProvider();
+const adenaSDK = new AdenaSDK(walletProvider);
+
+// Connect to the wallet

+  console.log('Account:', account);
+});
+```
+
+## SDK Functions
+
+### `connectWallet`
+
+Connects the SDK to the wallet.
+
+**Example:**
+
+```
+adenaSDK.connectWallet().then(() => {
+  console.log('Wallet connected');
+});
+```
+
+### `disconnectWallet`
+
+Disconnects the SDK from the wallet.
+
+**Example:**
+
+```
+adenaSDK.disconnectWallet();
+```
+
+### `getConnectionState`
+
+Retrieves the current connection state of the wallet.
+
+**Example:**
+
+```
+const state = adenaSDK.getConnectionState();
+console.log('Connection state:', state);
+```
+
+### `onConnectionChange`
+
+Sets up a listener for connection state changes.
+
+**Example:**
+
+```
+adenaSDK.onConnectionChange({
+  callback: (event) => {
+    console.log('Connection event:', event);
+  },
+});
+```
+
+### `offConnectionChange`
+
+Removes a previously set connection state change listener.
+
+**Example:**
+
+```
+const listener = (event) => {
+  console.log('Connection event:', event);
+};
+
+adenaSDK.onConnectionChange({ callback: listener });
+
+// Later, remove the listener
+adenaSDK.offConnectionChange({ callback: listener });
+```
+
+### `isConnected`
+
+Checks if the wallet is currently connected.
+
+**Example:**
+
+```
+adenaSDK.isConnected().then((response) => {
+  console.log('Is connected:', response.status);
+});
+```
+
+### `getAccount`
+
+Retrieves account information from the connected wallet.
+
+**Example:**
+
+```
+adenaSDK.getAccount().then((account) => {

+});
+```
+
+### `switchNetwork`
+
+Switches the wallet to a different network.
+
+**Example:**
+
+```
+adenaSDK.switchNetwork({ chainId: 'new-chain-id' }).then(() => {
+  console.log('Network switched');
+});
+```
+
+### `addNetwork`
+
+Adds a new network to the wallet.
+
+**Example:**
+
+```
+adenaSDK.addNetwork({

+}).then(() => {
+  console.log('Network added');
+});
+```
+
+### `signTransaction`

+```
+const tx = {
+    /** specific message types */
+    messages: Any[];
+    /** transaction costs (fee) */
+    fee?: TxFee;
+    /** the signatures for the transaction */
+    signatures: TxSignature[];
+    /** memo attached to the transaction */
+    memo: string;
+};
+
+adenaSDK.signTransaction({ tx }).then((response) => {
