## EIP-1559 Fee Mechanisms

EIP-1559 introduced a fundamental change to the transaction fee structure of the Ethereum network by implementing a base fee that is burned. This mechanism was designed to make transaction costs more predictable and to reduce the volatility of fees.

Users pay a base fee plus a priority fee (tip) to the validator. The base fee fluctuates based on the demand for block space, increasing when blocks are full and decreasing when they are empty.

This provides a clearer signal for users to set their fees. However, it also created new dynamics for searchers, who must now carefully manage their priority fees to ensure their transactions are included.

It has significantly changed the economics of MEV, as the cost of inclusion is now more transparently tied to network congestion.
