+
+# Best practices and recommendations
+
+:::note
+While your dapp can still interact with the existing EIP-1193 API (which is not optimized for Multichain), 
+we recommend starting directly with the Multichain API (using``wallet_createSession) if possible.
+Compatibility with the EIP-1193 API is mainly provided to help dapps that rely on third-party libraries with dependencies on EIP-1193.
+:::
+
+## Security considerations
+
+- Always validate input parameters to ensure that they are correct and expected.
+- Handle errors gracefully to avoid exposing sensitive information or causing crashes.
+- Implement proper error messages that are informative yet secure for users.
+
+## Performance optimization
+
+- Cache frequently used data to reduce repeated operations and improve performance.
+- Minimize unnecessary network requests to save bandwidth and reduce latency.
+- Handle connection state changes efficiently to maintain a stable user experience.
+
+## User experience
+
+- Provide clear and immediate feedback for user actions to keep them informed.
+- Display loading states during operations to show that the system is working.
+
+## Testing
+
+- Use test networks before deploying to mainnet to catch issues early in a safe environment.
+- Verify all error scenarios to ensure the system behaves as expected under all conditions.

+description: Get started with the MetaMask Flask Multichain API
+sidebar_position: 1
+---
+
+# Get started with MetaMask Multichain
+
+The [Multichain API](link-to-concepts-doc) allows your dapp to interact with multiple blockchain networks through a single interface.
+This includes managing network permissions through sessions, executing network-specific tasks, monitoring wallet and blockchain events, and conducting transactions across different networks.
+
+This guide will help you integrate MetaMask's Multichain API into your dapp development process. 
+
+## Prerequisites
+
+- You have installed [MetaMask Flask](../../../../snaps/get-started/install-flask/)
+
+:::note
+Install Flask in a new browser profile or disable existing MetaMask versions.
+Do not import production wallets into Flask - use test accounts only.
+Running multiple MetaMask instances in the same profile can cause conflicts.
+:::
+
+:::warning
+We do not recommend importing your "Secret Recovery Phrase" from MetaMask stable to MetaMask Flask. 
+Importing accounts with funds into Flask is not advised.
+:::
+
+## Use the Multichain API
+
+### 1. Configure you development environment
+
+You'll need to establish a connection to MetaMask Flask and set up basic message handling:
+
+```javascript
+// Initialize the connection to Flask.
+const FLASK_ID = "<your_id>";
+const extensionPort = chrome.runtime.connect(FLASK_ID);
+
+// Set up message listener for various events.
+extensionPort.onMessage.addListener((msg) => {
+  if (msg.data.method === "wallet_notify") {
+    console.log("wallet_notify:", {
+      scope: msg.data.params.scope,
+      method: msg.data.params.notification.method,
+      subscription: msg.data.params.notification.params.subscription,
+      number: msg.data.params.notification.params.result.number
+    });
+    return;
+  }
+  console.log(msg.data);
+});
+```
+
+### 2. Managing sessions
+
+Sessions in the Multichain API control what your dapp can do across different networks. There are two key operations:
+
+#### 2.1 Check existing sessions
+
+Before creating a new session, check if one already exists:
+
+```javascript
+extensionPort.postMessage({
+  type: "caip-x",
+  data: {
+    jsonrpc: "2.0",
+      method: "wallet_getSession",
+      params: {}
+  }
+});
+```
+
+If the result returns an empty `sessionScopes` parameter, then a multichain session is not active. 
+You must initiate a new one by calling `wallet_createSession` with `optionalScopes` specified.
+
+#### 2.2 Create a new session
+
+When creating a session, specify which chains and methods your dapp needs access to:
+
+```javascript
+extensionPort.postMessage({
+  type: "caip-x",
+  data: {
+    jsonrpc: "2.0",
+    method: "wallet_createSession",
+    params: {
+      optionalScopes: {
+        "wallet:eip155": {
+          methods: ["wallet_addEthereumChain"],
+          notifications: [],
+          accounts: []
+        },
+        "eip155:1": {
+          methods: [
+            "personal_sign",
+            "eth_blockNumber",
+            "eth_getBalance",
+            "eth_sendTransaction"
+          ],
+          notifications: ["eth_subscription"],
+          accounts: []
+        }
+      }
+    }
+  }
+});
+```
+
+The `optionalScope` you request should align with the chains your dapp intends to interact with initially. 
+If the EVM chain you’ve requested is not configured with an RPC network by the user, you might need to use the `wallet_addEthereumChain` method to add it.
+
+The requested methods should correspond to the methods your dapp expects to call at any time. 
+The methods listed in each `sessionScope` of the response indicate which wallet capabilities your dapp can use during the session.
+
+:::note
+Request only the chains your dapp needs.
+Ensure you specify required methods for each chain.
+:::
+
+#### 2.3 Create a new session
+
+To ensure your dapp responds appropriately to changes in the wallet session, such as network or account updates, you can listen for the `wallet_sessionChanged` event. Based on the event data, you can determine whether your dapp needs to request additional permissions:
+
+```javascript
+extensionPort.onMessage.addListener((msg) => {
+  if (msg.data.method === 'wallet_sessionChanged') {
+  }
+});
+```
+
+### 3. Implement network operations using the Multichain API 
+
+The Multichain API allows your dapp to perform transactions across various networks, automatically managing gas fees and network-specific parameters.
+It supports tracking transaction status, addressing unique network requirements, and handling user approvals through MetaMask,
+making it easier to manage operations across multiple networks.
+
+#### 3.1. Sign messages
+
+Enable secure authentication and digital signatures across networks in your dapp. 
+Use this method to sign arbitrary messages, implement user authentication, and create secure verifiable messages: 
+
+```javascript
+const signMessage = async (address, message) => {
+  return extensionPort.postMessage({
+    type: "caip-x",
+    data: {
+      jsonrpc: "2.0",
+      method: "wallet_invokeMethod",
+      params: {
+        scope: "eip155:1",
+        request: {
+          method: "personal_sign",
+          params: [message, address]
+        }
+      }
+    }
+  });
+};
+```
+
+#### 3.2. Check balances
+
+Monitor user balances across different networks:
+
+```javascript
+const getBalance = async (address, chainId = "eip155:1") => {
+  return extensionPort.postMessage({
+    type: 'caip-x',
+    data: {
+      jsonrpc: "2.0",
+      method: "wallet_invokeMethod",
+      params: {
+        scope: chainId,
+        request: {
+          method: "eth_getBalance",
+          params: [address, "latest"]
+        }
+      }
+    }
+  });
+};
+```
+
+#### 3.3. Send transactions
+
+Enable your dapp to send transactions between supported networks while managing gas parameters specific to each network:
+
+```javascript
+const sendTransaction = async (params) => {
+  return extensionPort.postMessage({
+    type: "caip-x",
+    data: {
+      jsonrpc: "2.0",
+      method: "wallet_invokeMethod",
+      params: {
+        scope: "eip155:1",
+        request: {
+          method: "eth_sendTransaction",
+          params: [{
+            from: params.from,
+            to: params.to,
+            value: params.value,
+            gasLimit: params.gasLimit,
+            maxPriorityFeePerGas: params.maxPriorityFeePerGas,
+            maxFeePerGas: params.maxFeePerGas
+          }]
+        }
+      }
+    }
+  });
+};
+```
