Overview

When you’re building crypto apps with AI help, things often go wrong with wallets, network connections, and transactions. This guide shows you a simple, step-by-step way to debug these issues. Here’s how to debug effectively using AI:
  • Isolate: Create a simple example that shows the exact problem
  • Analyze: Give the AI context about your app and what you were trying to do
  • Fix: Ask for a solution that’s secure and handles edge cases
  • Prevent: Get tests written so this bug doesn’t happen again

​
Debug prompt template

Here’s a template you can copy and fill in: 
"Debug this issue in my [app type]:

Error: [exact message]
Expected vs Actual: [one line]
Environment: [browser/network/wallet]

Minimal code:
[paste tiny repro]

Please provide:
1) Likely root cause(s)
2) Corrected code
3) Safer pattern to avoid this
4) Tests to prevent regression (framework: [Jest/Vitest])"

​
Process

1

1. Isolate

Copy this prompt:
"Issue with [functionality]:

Expected: [expected behavior]
Actual: [actual behavior]
Error: [exact error message]
Environment: [browser/network/wallet]

Minimal code: [paste minimal example]"
2

2. Analyze

Copy this prompt:
"Context for this issue:

App type: [wallet/DeFi/trading]
User flow: [what user was doing]
Recent changes: [what changed]
Similar working code: [paste if any]

Could any of these factors contribute?"

3. Fix

Copy this prompt:
"Need a solution that:
1. Fixes the immediate issue
2. Follows security best practices
3. Handles edge cases like [specific cases]
4. Integrates with existing patterns

Provide corrected code with explanations."

4. Prevent

Copy this prompt:
"Create tests for this fix:

Fixed code: [paste solution]
Test scenarios: [edge cases to cover]
Framework: [Jest/Vitest]

Generate tests covering the bug and related cases."

How to prevent bugs

​
Always review AI code

Use this prompt to get the AI to check its own work: 
"Review your generated code for:
- Common crypto development mistakes
- Security vulnerabilities  
- Performance issues
- Integration problems

Provide critical analysis and improvements."

​
Generate tests with code

Ask for tests when you request features: 
"Generate [feature] with comprehensive tests:

Requirements: [feature needs]
Context: [existing code]

Provide implementation plus unit/integration/error tests."

​
Ask for explanations

Don’t just ask for code, ask the AI to explain its decisions: 
"Implement [feature] with detailed explanations:

Requirements: [needs]
Context: [existing code]

Explain each major decision and potential issues."

​
Common crypto app errors

​
Transaction errors

When transactions fail, try this: 
Pattern: "execution reverted" or "transaction failed"
Causes: Insufficient gas, invalid parameters, network congestion

Debug: "Transaction reverting: [error]. Details: [transaction object]. Help identify why."

​
Connection errors

When wallets won’t connect, try this: 
Pattern: "wallet not connected" or "provider not found"  
Causes: Missing extension, wrong network, state management issues

Debug: "Users can't connect: [error]. Code: [connection logic]. What to check?"

​
State errors

When your app’s state gets messed up, try this: 
Pattern: "Cannot read property of undefined" or infinite re-renders
Causes: Missing dependencies, race conditions, memory leaks

Debug: "State management issues: [symptoms]. Code: [component]. Fix patterns?"

More debugging tips

​
Compare working vs broken code

Try this when you have a working example: 
"My code isn't working: [paste broken code]

Working example: [paste working code or link]

What's different and why might mine fail? How should I fix it?"

​
Break down complex problems

When the issue is complicated, try debugging piece by piece: 
"Complex issue with [feature]:

Part 1 - Basic functionality: [code] - Does this work?
Part 2 - Integration: [describe] - How should this integrate?
Part 3 - Edge cases: [describe] - What cases to handle?

Debug each part systematically."

​
When something breaks later

If your feature worked before but now it’s broken: 
"Feature worked before but now broken:

Last working: [commit/description]
Current error: [error message]
Recent changes: [list changes]

What change likely caused this regression?"
