+# Developing on Fork
+
+This guide shows how to run and interact with a local fork of Starknet mainnet.
+
+## Setup
+
+1. Start the fork:
+```bash
+yarn chain --fork-network https://starknet-mainnet.public.blastapi.io/rpc/v0_7
+```
+
+2. Update scaffold.config.ts:
+```typescript
+const mainnetFork = {
+  id: BigInt("0x534e5f4d41494e"),
+  network: "devnet",
+  name: "Starknet Fork",
+  nativeCurrency: {
+    address: "0x49d36570d4e46f48e99674bd3fcc84644ddd6b96f7c741b1562b82f9e004dc7",
+    name: "Ether",
+    symbol: "ETH",
+    decimals: 18,
+  },
+  testnet: true,
+  rpcUrls: {
+    default: {
+      http: ["http://127.0.0.1:5050/rpc"],
+    },
+    public: {
+      http: ["http://127.0.0.1:5050/rpc"],
+    },
+  },
+} as Chain;
+
+const scaffoldConfig = {
+  targetNetworks: [mainnetFork],
+  // ... other config options remain the same
+};
+```
+
+## Wallet Configuration
+
+### Using Argent/Braavos
+1. Open your wallet
+2. Add Custom Network:
+   - RPC URL: http://127.0.0.1:5050/rpc

+
+## Interaction
+Navigate to `/debug-ui` to interact with your contracts
+
+## Notes
+- Make sure your contract deployment is complete before testing
+- The burner wallet is automatically configured with test ETH
+- External wallets need to be configured with the correct network settings
