The EIP-1559 Fee Model
ETH Transaction Price Explained Simply
Before 2021, Ethereum used a simple first-price auction: users bid gas prices and miners chose the highest offers. This system caused extreme fee volatility. EIP-1559 (London Hard Fork, August 2021) replaced it with a two-component model: a Base Fee that adjusts automatically every block ±12.5% based on network utilization, and an optional Priority Fee (tip). The total cost is: Total Fee = Gas Used × (Base Fee + Priority Fee). The Base Fee is permanently burned, reducing ETH supply.

Key Facts
Below are the most important facts about this topic, based on current Ethereum network data and research from leading blockchain analytics providers.
- Network Demand Rises: More users compete for block space. Blocks fill to >50% of the gas limit target.
- Base Fee Adjusts Up: Per EIP-1559, each full block raises the base fee by up to 12.5% for the next block.
- Users Add Priority Tips: To ensure inclusion, users offer a small tip above the base fee. High-priority users tip more.
- Transaction Confirmed: Validators include transactions with sufficient fees. Base fee is burned; tip goes to validators.
Do I lose my gas fee if a transaction fails?
Yes. Gas fees compensate validators for computational work regardless of transaction outcome. Even failed transactions consume gas.
What happens to the ETH base fee?
The base fee is permanently burned (removed from supply), making ETH deflationary during high-activity periods under EIP-1559.
