Here are the highest gas fees ever recorded for single Ethereum transactions:
Absolute Records
Highest Gas Fee Ever Paid:
-
10,000 ETH ($15.3 million at the time, ~$40 million today)
-
When: September 2021
-
What happened: A user accidentally set a 10,000 ETH gas fee for a simple transfer during network congestion
Second Highest:
-
2,500 ETH (~$7.5 million at the time)
-
When: May 2022
-
Context: Another fat-finger error during high congestion
Extreme but "Normal" Highs
During Peak Bull Markets:
-
2021 Peak: Average fees reached 200-400 gwei, with priority fees sometimes hitting 1,000+ gwei
-
Highest gas price paid (not total fee): ~2,500 gwei for urgent transactions during extreme congestion
-
Typical cost: $200-$500 for simple transfers, $1,000+ for complex DeFi transactions
Post-Merge (Post-EIP-1559)
-
Record base fee: ~400-500 gwei during extreme events
-
Highest priority fees: Up to 1,000+ gwei during MEV opportunities
Recent Context (2023-2024)
-
Ordinals/Inscriptions craze (May 2023): Average fees spiked to 200+ gwei
-
Peak costs: $100-$300 for simple transactions
-
Current (late 2024): Typically 10-50 gwei ($1-$10 per transaction)
Key Factors Driving Extreme Fees:
-
Network congestion during bull markets
-
MEV (Maximal Extractable Value) opportunities
-
Gas token minting (CHI, GST2) during low-fee periods
-
Protocol launches/mints (NFTs, token sales)
-
User errors setting gas price instead of total ETH
Most Expensive Transaction Types:
-
Complex smart contract interactions (DeFi arbitrage, liquidations)
-
Contract deployments
-
Batch transactions
-
Bridge interactions
The transition to Ethereum 2.0 and layer-2 scaling solutions has significantly reduced these extreme fee events, though occasional spikes still occur during major market events.
