Ethereum Gas Fee History

Ethereum gas fees have followed a dramatic arc since the network launched in July 2015. In the early years, fees were negligible — fractions of a cent — because demand was low and blocks were mostly empty. As Ethereum's DeFi ecosystem grew through 2020 and 2021, transaction costs soared to levels that priced out casual users entirely.

The first major fee spike came in 2020 during 'DeFi Summer'. Protocols like Compound, Uniswap, and Yearn Finance drove enormous on-chain activity. Average gas prices exceeded 220 Gwei in September 2020, pushing average transaction fees above $10. For complex DeFi interactions involving multiple contract calls, users regularly paid $50–$100 per transaction.

2021 saw the all-time high: on May 10, 2021, the average ETH transaction fee reached $53.16. This coincided with peak NFT market activity and broad crypto market euphoria. Gas prices regularly exceeded 300 Gwei during this period, making Ethereum essentially unusable for small-value transactions.

The London Hard Fork in August 2021 introduced EIP-1559, reforming the fee market. While this improved fee predictability, it did not dramatically reduce costs on its own — network demand remained high. Real relief came from Layer 2 adoption through 2022–2023, and from the broader market correction that reduced on-chain activity.

By 2025, the landscape had transformed. Average ETH transaction fees stabilized below $1, frequently reaching lows of $0.16–$0.36 on quiet days. Average gas prices fell from 220+ Gwei in 2020–2021 to just 1–3 Gwei in 2025. The February 2025 average fee of $0.76 represented a decline of over 96% from the February 2021 average of $24.25.

Always check the current gas price before sending ETH or interacting with a smart contract. A few minutes of patience can save significant fees.
