Gas rebates

Introduction to Ethereum's gas fee

All Ethereum transaction require a gas fee to be included onchain. This gas fee can be broken down into two categories:

• Base fee - A required network fee that automatically adjusts based on network demand for blockspace. The baseFee ensures that if transactions pay such fee, they are processed and included in a block.
• Priority fee - An optional additional payment for builders to include your transaction faster than others. The priorityFee allows builders to tip make a more valuable block and hence, gives you a higher chance of fast inclusion in a block.

How MEV Blocker recovers priority fees

MEV blocker is the only RPC that has a permissionless Order Flow Auction for which both searchers and builders are bound to public rules. To this date, MEV Blocker processes around 10% of daily Ethereum transactions.

MEV Blocker currently protects and routes over 20% of all Ethereum mainnet transactions daily. It maintains strong relationships with top block builders—the entities responsible for selecting and packaging transactions into Ethereum blocks.

Through our wide-reaching network and direct integration with the transaction path, MEV Blocker can recover part of the priority fee that would otherwise be lost—all without introducing delays or compromising transaction speed.

As Ethereum evolves under the Proposer-Builder Separation (PBS) model, where validators (proposers) and block builders have distinct roles, gas pricing dynamics are shifting. While this opens the door for a more transparent and efficient fee market, users still often overspend to secure inclusion.

MEV Blocker steps in to bridge that gap—helping users recapture the excess between what they paid and what was actually needed: unlocking refunds from the inefficiencies of the current gas fee system.
