Errors and Issues Summary

🔴 Critical Errors (Must Fix)

1. Frontend TypeScript Error - defineChain

File: frontend/lib/web3/config.ts:2 Error: 'wagmi/chains' has no exported member named 'defineChain' Status: ⚠️ Type checking fails Solution: In wagmi v2, use viem's defineChain instead:

import { defineChain } from "viem";

2. Backend TypeScript Compilation Errors

File: backend/tsconfig.json Errors:

Missing ES2021 lib (for replaceAll method)
Missing DOM lib (for window types in dependencies) Status: ✅ FIXED - Updated tsconfig.json lib to ["ES2021", "DOM"]

⚠️ Warnings (Should Fix)

Unused Imports/Variables (14 warnings)

Multiple unused imports across frontend files
Unused variables in error handlers and components
Fix: Remove unused imports, use proper types

Type Safety Issues

Using any type in 4 locations instead of proper types
Fix: Use unknown or Error for error handlers, define proper interfaces

React Hooks

useEffect dependency issue in RecentActivity component
Fix: Wrap transactions array in useMemo()

📝 Implementation TODOs (9 items)

Backend indexer needs completion
Frontend components need backend API integration
These are expected for MVP phase
