EIP-1559
Ethereum's 2021 fee market upgrade that introduced base fee burning and improved transaction fee predictability.
EIP-1559 — EIP-1559 is an Ethereum Improvement Proposal implemented in August 2021 that reformed Ethereum's transaction fee mechanism. It introduced a base fee that adjusts dynamically based on network demand, a priority tip for validators, and a burn mechanism that permanently destroys a portion of every transaction fee, making ETH potentially deflationary.
What Is EIP-1559?
Before EIP-1559, Ethereum used a first-price auction for gas fees — users bid against each other, leading to overpayment and unpredictable costs. EIP-1559 replaced this with a two-component system: a base fee set by the protocol (adjusting up or down based on block utilization) and an optional priority fee (tip) paid directly to validators for faster inclusion.
The base fee is burned — permanently removed from circulation — rather than paid to validators. This creates deflationary pressure on ETH supply proportional to network usage.
How EIP-1559 Works
Each block has a target gas usage of 15 million gas. If a block exceeds this target, the base fee increases by up to 12.5% for the next block. If usage falls below the target, the base fee decreases. This mechanism creates more predictable fees and ensures blocks are never completely full under normal conditions, reducing transaction wait times.
EIP-1559 and ETH Economics
The burn mechanism has destroyed millions of ETH since implementation. During periods of high network activity, more ETH is burned than issued to validators, making ETH net deflationary. This 'ultrasound money' narrative has become a key part of Ethereum's investment thesis, as increasing usage leads to decreasing supply.

Common questions about EIP-1559 in cryptocurrency and DeFi.
Over 4 million ETH has been burned since EIP-1559 launched in August 2021. The daily burn rate varies with network usage — ranging from hundreds to thousands of ETH per day during peak activity.
EIP-1559 does not reduce gas costs but makes them more predictable. Users no longer need to guess appropriate gas prices. The base fee mechanism prevents extreme overpayment during congestion spikes.
The priority fee (tip) is an optional payment directly to the validator that includes your transaction. Higher tips incentivize faster inclusion during congestion. During low-activity periods, a minimal tip (1-2 gwei) is sufficient.
