+# E2E Testing Setup Guide
+
+## Overview
+
+These tests use Playwright to launch a Chromium instance with selected wallet extensions. The required extensions (OKX, Keplr, etc.) download automatically as part of the test setup.
+
+You need to provide your 12 words mnemonic and a password (that is used for the Chrome extension) in `.env.local`:
+
+```env
+E2E_WALLET_MNEMONIC="one two three four five six seven eight nine ten eleven twelve"
+E2E_WALLET_PASSWORD="SomePasswordWithSymbols"
+```
+
+Use the following command to run the E2E tests:
+
+```bash
+npm run test:e2e
+```
+
+Additional test commands:
+
+```bash
+npm run test:e2e:ui      # Run tests with UI
+npm run test:e2e:debug   # Run tests in debug mode
+npm run test:e2e:headed  # Run tests in headed mode
+```
