+## Troubleshooting
+
+### ReferenceError: Can't find variable: BigInt using React
+
+Occasionally, users encounter errors in web3.js due to external dependencies, which may seem challenging to resolve within the web3.js framework alone.
+
+**Resolution Steps:**
+
+1. Install `rn-nodeify` as a development dependency:
+```bash
+yarn add --dev rn-nodeify
+```
+
+2. Add the `big-integer` package:
+```bash
+yarn add big-integer
+```
+
+3. Create a file named `shim.js` at the root of your project and include the following polyfill:
+```ts
+if (typeof BigInt === 'undefined') {
+    global.BigInt = require('big-integer');
+}
+```
+
+4. Import shim.js at the top of your App.js:
+```ts
+// Make sure you use `import` and not `require`!
+import './shim.js'
+```
