+# PR #24 Review Suggestions Implementation
+
+This document details the exact implementation of all review suggestions from PR #24.
+
+## Summary of Changes
+
+All review suggestions from PR #24 have been successfully implemented exactly as requested:
+
+### 1. Test Calculation Fix (test/SEQICO.test.js)
+
+**Review Suggestion:**
+> The calculation uses BigInt multiplication but could be clearer. Consider using `tokenAmount` instead of the hardcoded `10n` to make the relationship more explicit: `const requiredETH = newETHPrice * tokenAmount / ethers.parseEther('1');`
+
+**Implementation (Line 226):**
+```javascript
+// Before (as suggested in review):
+const requiredETH = newETHPrice * 10n;
+
+// After (implemented):
+const requiredETH = newETHPrice * tokenAmount / ethers.parseEther('1'); // 10 tokens * 0.005 ETH = 0.05 ETH
+```
+
+**Benefits:**
+- Uses variables instead of hardcoded values
+- Makes the relationship between price and tokens more explicit
+- Maintains precision in BigInt calculations
+- Added clear comment explaining the calculation
+
+### 2. Set-Prices Script Validation (scripts/set-prices.js)
+
+**Review Suggestion:**
+> The placeholder address should be more descriptive to prevent accidental deployment with invalid address. Consider using a more obvious placeholder like `'YOUR_DEPLOYED_SEQICO_ADDRESS_HERE'` or add validation to check if it's still the placeholder.
+
+**Implementation (Lines 5-12):**
+```javascript
+// Before (as suggested in review):
+const SEQICO_ADDRESS = "0x..."; // Replace with your deployed SEQICO address
+
+// After (implemented):
+const SEQICO_ADDRESS = "YOUR_DEPLOYED_SEQICO_ADDRESS_HERE"; // <-- Replace with your deployed SEQICO address
+if (
+  !SEQICO_ADDRESS ||
+  SEQICO_ADDRESS === "YOUR_DEPLOYED_SEQICO_ADDRESS_HERE" ||
+  SEQICO_ADDRESS === "0x..." ||
+  !/^0x[a-fA-F0-9]{40}$/.test(SEQICO_ADDRESS)
+) {
+  throw new Error("❌ Please set SEQICO_ADDRESS to your deployed SEQICO contract address before running this script.");
+}
+```
+
+**Benefits:**
+- More descriptive placeholder that's harder to miss
+- Comprehensive validation checking multiple invalid states
+- Clear error message guiding users
+- Regex validation for proper Ethereum address format
+- Prevents accidental execution with placeholder values
+
+## Additional Comprehensive Implementation
+
+Beyond the specific review suggestions, the complete PR #24 functionality was implemented:
+
+### SEQICO Contract Enhancements
+- Added price setter functions: `setPriceETH()`, `setPriceUSDT()`, `setPriceUSDC()`
+- Implemented $3 minimum price validation
+- Added `PriceUpdated` event for transparency
+- Constructor validation for initial prices
+
+### Test Suite
+- Comprehensive test coverage for all price-setting functions
+- Edge case testing (below, at, and above minimums)
+- Owner-only access control verification
+- Integration testing with purchase functionality
+
+### MockERC20 Contract
+- Created for proper testing of ERC20 interactions
+- Configurable decimals for USDT/USDC simulation
+
+## Files Created/Modified
+
+1. **test/SEQICO.test.js** - Complete test suite with review fix applied
+2. **scripts/set-prices.js** - Price-setting utility with review fix applied
+3. **contracts/SEQICO.sol** - Enhanced with price-setting functionality
+4. **contracts/MockERC20.sol** - Test helper contract
+5. **package.json** - Updated with proper test scripts
+6. **hardhat.config.js** - ES module configuration
+
+## Verification
+
+Both review suggestions have been implemented exactly as specified:
+
+✅ **Test calculation**: Now uses `newETHPrice * tokenAmount / ethers.parseEther('1')` instead of hardcoded values
+✅ **Set-prices validation**: Uses descriptive placeholder with comprehensive validation
+
+The implementation follows best practices for:
+- Clear, self-documenting code
+- Robust error handling
+- Comprehensive testing
+- Security validation
