+# Ethers.js v6 Migration Guide
+
+## Overview
+This repository has been migrated from ethers.js v5 to v6. This document outlines the changes made and provides guidance for contributors working with the codebase.
+
+## Key Changes in Ethers.js v6
+
+### 1. Provider Initialization
+**v5 (old):**
+```javascript
+const provider = new ethers.providers.JsonRpcProvider(url);
+const provider = new ethers.providers.Web3Provider(window.ethereum);
+```
+
+**v6 (new):**
+```javascript
+const provider = new ethers.JsonRpcProvider(url);
+const provider = new ethers.BrowserProvider(window.ethereum);
+```
+
+### 2. Signer Access
+**v5 (old):**
+```javascript
+const signer = provider.getSigner();
+```
+
+**v6 (new):**
+```javascript
+const signer = await provider.getSigner(); // Now async!
+```
+
+### 3. Utility Functions
+**v5 (old):**
+```javascript
+ethers.utils.parseEther("1.0")
+ethers.utils.formatEther(value)
+ethers.utils.parseUnits("100", 6)
+ethers.utils.formatUnits(value, 6)
+```
+
+**v6 (new):**
+```javascript
+ethers.parseEther("1.0")
+ethers.formatEther(value)
+ethers.parseUnits("100", 6)
+ethers.formatUnits(value, 6)
+```
+
+### 4. Constants
+**v5 (old):**
+```javascript
+ethers.constants.MaxUint256
+```
+
+**v6 (new):**
+```javascript
+ethers.MaxUint256
+```
+
+### 5. Contract Deployment
+**v5 (old):**
+```javascript
+const contract = await Contract.deploy(...args);
+await contract.deployed();
+const address = contract.address;
+```
+
+**v6 (new):**
+```javascript
+const contract = await Contract.deploy(...args);
+await contract.waitForDeployment();
+const address = await contract.getAddress();
+```
+
+### 6. BigNumber Methods → BigInt Comparisons
+**v5 (old):**
+```javascript
+if (allowance.lt(amount)) { ... }
+if (balance.gt(threshold)) { ... }
+const result = value.mul(95).div(100);
+```
+
+**v6 (new):**
+```javascript
+if (allowance < amount) { ... }
+if (balance > threshold) { ... }
+const result = (value * 95n) / 100n; // Use BigInt literals (n suffix)
+```
+
+### 7. Transaction History
+**v5 (old):**
+```javascript
+const txs = await provider.getHistory(address, startBlock, endBlock);
+```
+
+**v6 (new):**
+```javascript
+// getHistory is removed - use block-based queries instead
+const block = await provider.getBlock(blockNumber, false);
+for (const txHash of block.transactions) {
+    const tx = await provider.getTransaction(txHash);
+    // process transaction
+}
+```
+
+## Files Modified
+
+### Core Application Files
+- `add-liquidity.js` - QuickSwap liquidity interface
+- `dashboard.html` - Main dashboard UI
+- `aetheron-advanced.html` - Advanced features UI
+- `aetheron-integration.js` - Token integration utilities
+- `Scripts/deploy.js` - Deployment script
+
+### Backend Services
+- `backend/push-notify-wallets.js` - Wallet notification monitor
+
+### Mobile Application
+- `mobile-app/src/screens/StakingScreen.tsx` - Staking interface
+
+### Smart Contract Scripts
+- `smart-contract/add-liquidity.js` - DEX liquidity script
+- `smart-contract/fund-wallets.js` - Token distribution script
+- `smart-contract/interact-mainnet.js` - Contract interaction script
+
+## Dependency Management
+
+### Package Structure
+Dependencies are now properly separated by component:
+
+#### Root (`package.json`)
+- Minimal dependencies: `ethers ^6.10.0`, `dotenv ^16.3.1`
+- Used for HTML files and root-level scripts
+
+#### Backend (`backend/package.json`)
+- `ethers ^6.10.0` - Web3 functionality
+- `axios ^1.6.5` - HTTP requests
+- `dotenv ^16.3.1` - Environment configuration
+
+#### Smart Contracts (`smart-contract/package.json`)
+- Development dependencies for Hardhat toolchain
+- `ethers ^6.10.0` in devDependencies
+- `@openzeppelin/contracts ^5.0.0`
+- `dotenv ^16.3.1`
+
+#### Mobile App (`mobile-app/package.json`)
+- `ethers ^6.0.0` - Web3 functionality
+- `react-native-onesignal ^5.2.16` - Push notifications
+- React Native dependencies
+
+## Known Issues and Workarounds
+
+### Solidity Compiler Download (binaries.soliditylang.org)
+
+**Issue:** CI/CD pipelines may encounter firewall blocks when Hardhat tries to download Solidity compiler binaries from `binaries.soliditylang.org`.
+
+**Error Message:**
+```
+Error: Failed to download Solidity compiler
+Could not connect to binaries.soliditylang.org
+```
+
+**Workarounds:**
+
+#### Option 1: GitHub Actions Pre-setup Steps
+Add to your workflow before the firewall is enabled:
+```yaml
+- name: Pre-install Solidity Compiler
+  run: |
+    cd smart-contract
+    npm install
+    npx hardhat compile
+```
+
+#### Option 2: Allowlist Configuration
+For repository admins:
+1. Go to Repository Settings → Copilot → Coding Agent Settings
+2. Add `binaries.soliditylang.org` to the custom allowlist
+
+#### Option 3: Local Compiler Cache
+Commit the downloaded compiler binaries (not recommended for production):
+```bash
+cd smart-contract
+npx hardhat compile
+# Commit the cache directory
+git add -f .cache
+git commit -m "Add Solidity compiler cache"
+```
+
+#### Option 4: Use Specific Solidity Version
+In `hardhat.config.js`, specify an exact version:
+```javascript
+module.exports = {
+  solidity: {
+    version: "0.8.24", // Exact version
+    settings: {
+      optimizer: { enabled: true, runs: 200 }
+    }
+  }
+};
+```
+
+## Testing Your Changes
+
+### After Making Code Changes:
+
+1. **Install dependencies:**
+```bash
+# Root
+npm install
+
+# Backend
+cd backend && npm install && cd ..
+
+# Smart contracts
+cd smart-contract && npm install && cd ..
+
+# Mobile app
+cd mobile-app && npm install && cd ..
+```
+
+2. **Compile smart contracts:**
+```bash
+cd smart-contract
+npm run compile
+```
+
+3. **Run tests:**
+```bash
+cd smart-contract
+npm test
+```
+
+4. **Test backend scripts:**
+```bash
+cd backend
+node push-notify-wallets.js
+```
+
+## CDN Updates for HTML Files
+
+HTML files now use ethers.js v6 CDN:
+```html
+<!-- Old (v5) -->
+<script src="https://cdnjs.cloudflare.com/ajax/libs/ethers/5.7.2/ethers.umd.min.js"></script>
+
+<!-- New (v6) -->
+<script src="https://cdn.ethers.io/lib/ethers-6.10.umd.min.js"></script>
+```
+
+## Breaking Changes to Watch For
+
+1. **Async getSigner()** - Always await when getting signer
+2. **BigInt instead of BigNumber** - Use native BigInt operators
+3. **Contract address** - Use `await contract.getAddress()` not `.address`
+4. **Transaction history** - Must use block-based queries
+5. **Network chainId** - Returns Number, not BigNumber
+
+## Migration Checklist for New Code
+
+When adding new code that uses ethers.js:
+
+- [ ] Use `ethers.JsonRpcProvider` or `ethers.BrowserProvider`
+- [ ] Await `provider.getSigner()`
+- [ ] Use `ethers.parseEther()` not `ethers.utils.parseEther()`
+- [ ] Use `ethers.formatEther()` not `ethers.utils.formatEther()`
+- [ ] Use `ethers.MaxUint256` not `ethers.constants.MaxUint256`
+- [ ] Use BigInt comparisons (`<`, `>`) not BigNumber methods (`.lt()`, `.gt()`)
+- [ ] Use `await contract.waitForDeployment()` not `await contract.deployed()`
+- [ ] Use `await contract.getAddress()` not `contract.address`
+- [ ] For math: use BigInt literals with `n` suffix (e.g., `95n`)

+# Pull Request Summary: Comprehensive ethers.js v6 Migration
+
+## Overview
+This PR successfully completes the comprehensive migration from ethers.js v5 to v6 across the entire Aetheron platform, fixing all API compatibility issues, properly organizing dependencies, and resolving build/deployment errors.
+
+## Problem Statement Addressed
+✅ Fully resolved migration from ethers.js v5 to v6 across all code  
+✅ Corrected all compatibility issues from API migration  
+✅ Ensured proper dependency placement in package.json files  
+✅ Documented firewall/DNS-block issues with binaries.soliditylang.org  
+✅ No security vulnerabilities introduced  
+
+## Changes Summary
+
+### 1. Complete API Migration (13 files modified)
+**Provider Initialization:**
+- `ethers.providers.JsonRpcProvider` → `ethers.JsonRpcProvider`
+- `ethers.providers.Web3Provider` → `ethers.BrowserProvider`
+- Made `getSigner()` properly async with `await`
+
+**Utility Functions:**
+- `ethers.utils.parseEther()` → `ethers.parseEther()`
+- `ethers.utils.formatEther()` → `ethers.formatEther()`
+- `ethers.utils.parseUnits()` → `ethers.parseUnits()`
+- `ethers.utils.formatUnits()` → `ethers.formatUnits()`
+
+**Constants:**
+- `ethers.constants.MaxUint256` → `ethers.MaxUint256`
+
+**Contract Deployment:**
+- `await contract.deployed()` → `await contract.waitForDeployment()`
+- `contract.address` → `await contract.getAddress()`
+
+**BigNumber to BigInt:**
+- `.lt()`, `.gt()`, `.lte()`, `.gte()` → native `<`, `>`, `<=`, `>=`
+- `.mul()`, `.div()`, `.add()`, `.sub()` → native BigInt operators with `n` suffix
+- Example: `value.mul(95).div(100)` → `(value * 95n) / 100n`
