Retry mechanism for verification in multiple explorers #487

0xLaz3r · 2025-09-01T14:01:29Z

Enhanced Contract Verification with Retry Mechanisms and Multi-Explorer Support

🎯 Summary

Enhances scripts/verify.py to eliminate single points of failure when verifying Sky Protocol spells. Adds robust retry mechanisms and support for multiple block explorers (Etherscan + Sourcify) with automatic fallback.

🔧 Key Changes

Retry Mechanisms

Exponential backoff with jitter for all API calls and subprocess operations
Configurable retry parameters: 3 attempts, 2s base delay, 60s max delay
Smart error handling with detailed logging

Multi-Explorer Support

Etherscan: Primary verifier (requires API key)
Sourcify: Backup verifier (no API key required)
Automatic fallback: If one fails, tries the next

Enhanced Error Handling

Graceful degradation when verifiers are unavailable
Comprehensive logging of all attempts and failures
Better error messages with clear failure reasons

📝 Files Changed

scripts/verify.py - Enhanced with retry mechanisms and multi-verifier support
scripts/verification/README.md - Updated documentation
scripts/verification/test_retry.py - Simple test for the retry mechanism

⚙️ Usage (Unchanged)

make verify addr=0x1234567890123456789012345678901234567890

✅ Benefits

Reliability: Multiple verifiers eliminate single points of failure
Resilience: Handles temporary network issues gracefully
Transparency: Detailed logging shows exactly what's happening
Compatibility: Existing workflows work unchanged

🧪 Testing

✅ Python syntax validation
✅ Retry mechanism verification
✅ Argument validation
✅ Environment variable validation

🎯 Addresses Requirements

✅ Verify on at least 2 block explorers
✅ Proper retry mechanisms with sane defaults
✅ Maintain existing Makefile command
✅ Eliminate single point of failure

No breaking changes - pure enhancement with full backward compatibility.

Should this hardcoded value be here? Isn't it also set somewhere else?
