๐ŸŽ“ L2 Gas Optimization Mastery

You've learned the fundamentals and advanced techniques of L2 gas optimization. Let's review the key concepts and test your knowledge!

๐Ÿ’ฐ

Fee Structure

  • โ€ขL2 fees = L2 execution + L1 data posting
  • โ€ขL1 data costs dominate (70-90% of total)
  • โ€ขCompression reduces calldata size by 60-80%
  • โ€ขBlob transactions 10-100x cheaper than calldata
๐ŸŽฏ

Optimization Basics

  • โ€ขBatching saves 40-70% by sharing overhead
  • โ€ขCalldata optimization reduces data size
  • โ€ขStrategic timing saves 20-50% (weekends)
  • โ€ขUse gas-optimized contract implementations
๐Ÿš€

Advanced Techniques

  • โ€ขStorage optimization: use memory when possible
  • โ€ขEIP-4844 blobs for massive savings
  • โ€ขIntent-based bundling shares costs
  • โ€ขAccount abstraction enables sponsorship

Key Insights

  • โ€ขL2s are 10-100x cheaper than L1
  • โ€ขOptimization can reduce costs another 50-90%
  • โ€ขMultiple strategies compound savings
  • โ€ขStay updated on new EIPs and L2 upgrades
