Updated readme.md with Deployment guide #5
Conversation
WalkthroughThis update introduces two new Git submodules for external contract dependencies, adds example environment configuration files for both backend and frontend, and modifies the documentation to include Ethereum Classic deployment instructions. It removes a Solidity mock contract, refactors the Chainvoice smart contract and its ABI, updates environment file handling and import statements, and adjusts frontend environment management. The frontend components are enhanced to encrypt and decrypt invoice data using Lit Protocol, integrating access control and secure data handling. Changes

4-4: Breaking change: Constructor no longer accepts parameters.The constructor now has an empty inputs array, which is a significant change from the previous interface. Ensure that any deployment scripts and frontend initialization code are updated accordingly.
757-760: Parameter renamed insetFeeAmountfunction.The parameter has been renamed from the previous name to

Breaking change:
getReceivedInvoicesnow requires an address parameter.The function signature has changed from
getMyReceivedInvoices()togetReceivedInvoices(address _address). This breaking change affects how the frontend retrieves received invoices.

🛠️ Refactor suggestion
Avoid parseFloat for ETH arithmetic
Floating-point math on token amounts can introduce rounding errors. Keep values in Wei (BigInt) and format only for display.

parseFloat on ETH amounts for arithmetic, which can cause rounding errors. To
fix this, keep all token amounts in Wei as BigInt for calculations, add them

ethers.formatUnits when displaying the result.

- Proper payload construction
- Correct access control conditions (sender OR receiver)
- Session signature generation
- Error handling for encryption/transaction failures

1-454: LGTM! ABI correctly reflects the updated contract interface.The ABI has been properly updated to support the new encrypted invoice approach, with simplified function signatures and appropriate event indexing. The changes are consistent with the contract's shift from storing detailed invoice data to encrypted payloads.

216-225: Payment function correctly uses Wei calculationsGood improvement! The payment function now properly converts amounts to Wei before arithmetic operations, avoiding floating-point precision issues.
539-556: React key property correctly addedGood fix! The
tbodyelements now have unique keys, resolving the React rendering issue flagged in previous reviews.

Potential null reference on user data
The code assumes invoice.user exists but doesn't handle cases where the decrypted data might be malformed or incomplete.
-const value = invoice.user[column.id] || "";
+const value = invoice.user?.[column.id] || "";
if (column.id === "to") {

🤖 Prompt for AI Agents
In frontend/src/page/ReceivedInvoice.jsx around lines 327 to 342, the code
assumes invoice.user is always defined, which can cause null reference errors if
the user data is missing or malformed. Add a check to ensure invoice.user exists
before accessing its properties, and provide a fallback UI or default value when
invoice.user is undefined or null to prevent runtime errors.

190-200: Client address validation still missingThe
data.clientAddressis used in access control conditions without validation, which was flagged in a previous review. A malformed address will cause the encryption to fail or behave unexpectedly.Add address validation before using it:

524-529: Individual item display calculation still uses floating-point arithmeticThe display value calculation for individual items uses
parseFloat, which creates inconsistency with the precise BigInt arithmetic used elsewhere. This was flagged in a previous review.Use the computed
amountfrom the item data instead:-value={ - (parseFloat(itemData[index].qty) || 0) * - (parseFloat(itemData[index].unitPrice) || 0) - - (parseFloat(itemData[index].discount) || 0) + - (parseFloat(itemData[index].tax) || 0) -} +value={itemData[index].amount}

68-81: Good improvement: Lit client initialization moved to useEffectThe Lit client is now properly initialized once in useEffect instead of on every function call, addressing the previous feedback about efficiency.
96-105: Excellent: Precise BigInt arithmetic for individual item calculationsThe individual item amount calculations now use
parseUnitsand BigInt arithmetic, which resolves the floating-point precision issues flagged in previous reviews.
51-66: Precise total calculation implementation looks solidThe total amount calculation properly uses BigInt arithmetic throughout, preventing floating-point precision errors. The logic correctly handles the multiplication and division scaling.
360-365: User address field correctly set to read-onlyThe user address input is properly set to read-only and pre-filled with the connected wallet address, preventing accidental modifications.
