0 / 5 completed⚡ Understanding L2 Gas Fees
Layer 2 solutions dramatically reduce gas costs, but their fee structures work differently from Ethereum. Understanding these mechanics is crucial for optimizing your transaction costs.
🎯 Why L2 Gas Matters
Cost Savings
L2 transactions cost 10-100x less than Ethereum mainnet
Different Mechanics
L2s have unique fee structures with L1 data costs
Optimization Opportunity
Smart strategies can reduce costs by another 50-90%

Ethereum L1
🔍 L1 vs L2 Gas: Key Differences
Two-Part Fee Structure
L2s charge for both execution (L2 gas) AND data availability (L1 posting). L1 only has execution costs.
Much Lower Base Fees
L2 execution is 10-100x cheaper (0.001 vs 30+ Gwei). Most L2 cost comes from L1 data fees, not execution.
Calldata Compression
L2s compress transaction data before posting to L1, reducing the dominant cost component by 3-10x.
Blob Transactions (EIP-4844)
New L2s use blob space instead of calldata, reducing L1 data costs by another 10-100x. This is the future!
L1 Gas (Ethereum)
- •Single fee: Gas Price × Gas Used
- •High base fees (30-200 Gwei typical)
- •Simple transfer: $5-50 depending on congestion
- •Complex contracts: $50-500+
L2 Gas (Rollups)
- •Two fees: L2 execution + L1 data posting
- •Tiny base fees (0.001-0.1 Gwei typical)
- •Simple transfer: $0.10-1.00 total
- •Complex contracts: $0.50-5.00 total
