EIP-1559

EIP-1559 is an Ethereum Improvement Proposal that changed how Ethereum mainnet transaction fees are priced. Activated as part of the London upgrade in 2021, it introduced a protocol-calculated base fee and an optional priority fee (tip). The base fee is burned, while the priority fee goes to the block proposer. The change affects fee calculation; it does not make transactions free or guarantee low fees.

How the Fee Market Works

The protocol adjusts the base fee from block to block using recent block usage relative to a target. When blocks use more gas than the target, the base fee rises; when usage is below the target, it falls. This provides a rule-based response to demand rather than relying only on users guessing a bid for inclusion.

A transaction can also include a priority fee to encourage a validator to include it sooner. Its maxFeePerGas sets the sender’s maximum total price per unit of gas, while maxPriorityFeePerGas caps the tip. The actual price is bounded by these settings and the block’s base fee; the unused part of the maximum fee is not charged. The transaction still pays for the gas it actually uses.

What the Base-Fee Burn Means

EIP-1559 removes the base fee from circulation instead of paying that portion to a block producer. Burning ETH does not by itself mean the total supply must fall. Net supply depends on how much ETH is issued compared with how much is burned over a given period. The “deflationary ETH” description is therefore conditional, not a permanent property guaranteed by this proposal.

What It Does—and Does Not—Change

The fee mechanism gives wallets a structured way to estimate a transaction’s cost and lets a sender set a ceiling. It does not remove competition for block space: when demand rises, the base fee can rise too, and complex transactions consume more gas than simple transfers. Wallet settings and fee estimates can still be confusing, so the maximum fee and likely total cost are different figures to understand before signing.

Social Media Sentiment

A July 11, 2026 r/ethereum discussion included a question about wallet fee defaults and a reply distinguishing the base fee from the priority fee. It is a practical, user-support-style exchange about understanding fee controls, not a poll or a measure of community-wide opinion.
