MEV-Burn is a protocol-level feature designed to capture and destroy a significant portion of the economic value that validators and searchers extract from transaction ordering, known as Maximal Extractable Value (MEV). Instead of this value being paid entirely to block proposers as a tip, the protocol automatically redirects a variable percentage of it to the base fee mechanism, where it is permanently burned, reducing the overall supply of ETH. This process transforms a form of network rent-seeking into a deflationary force for the native asset.

ETHEREUM PROTOCOL UPGRADE
What is MEV-Burn?
MEV-Burn is a core mechanism introduced in Ethereum's Dencun upgrade that permanently removes a portion of the value extracted by Maximal Extractable Value (MEV) from circulation by burning it.
The mechanism operates through Ethereum's proposer-builder separation (PBS) framework. Block builders, who compete to create the most profitable blocks, now include bids where a portion of the MEV profit is designated for burning. The winning block's burn amount is determined by a formula that considers network congestion, making the burn rate higher during periods of high demand. This design ensures the burn is market-driven and directly tied to the economic activity and inefficiencies MEV represents.
The primary goals of MEV-Burn are to enhance Ethereum's economic sustainability and improve validator economics. By burning a share of MEV, it reduces the net issuance of new ETH, complementing the existing EIP-1559 base fee burn. It also aims to democratize the benefits of MEV by redistributing some of its value to all ETH holders through deflation, rather than concentrating it solely with sophisticated block proposers. This addresses long-standing concerns about MEV centralizing power and profits.
For the network's security, MEV-Burn carefully balances the need to burn value with the need to sufficiently reward validators. The mechanism is parameterized to ensure that validators still receive enough incentive to perform their duties honestly, maintaining the security of the proof-of-stake consensus. The implementation is a key part of Ethereum's roadmap to mitigate the negative externalities of MEV and create a more equitable and efficient economic system for all participants.
etymology
TERM ORIGIN
Etymology & Origin
The term MEV-Burn describes a protocol-level mechanism designed to mitigate the negative externalities of Maximal Extractable Value (MEV) by redirecting a portion of that value to be permanently destroyed, or 'burned'.
The concept of MEV-Burn emerged as a direct response to the growing economic and security concerns posed by Maximal Extractable Value (MEV). MEV represents profit that sophisticated actors, often called searchers or validators, can extract by reordering, inserting, or censoring transactions within a block. This practice can lead to network congestion, increased transaction fees for regular users, and centralization pressures. MEV-Burn proposes to capture a share of this extracted value—often through mechanisms like priority fees or a portion of block rewards—and send it to a verifiably unspendable address, effectively removing it from the circulating supply.
The etymology of the term is a compound of "MEV" and "Burn." "Burn" is a well-established metaphor in cryptocurrency, originating from the act of sending tokens to a provably unspendable address (e.g., 0x000...dead), making them permanently inaccessible. This is analogous to burning physical currency. By combining it with "MEV," the term succinctly conveys the core function: the destruction of extracted value rather than its redistribution. This distinguishes it from other MEV mitigation strategies like MEV-Smoothing (redistributing MEV to validators) or MEV-Share (redistributing to users).
The theoretical and practical development of MEV-Burn is closely associated with Ethereum's post-merge roadmap. Following the transition to Proof-of-Stake, the proposer-builder separation (PBS) architecture created a clear delineation between block builders (who assemble blocks with MEV) and block proposers (who select them). This design made a direct, on-chain mechanism for capturing MEV more feasible. Proposals, such as those involving eip-1559's base fee or a portion of the priority fee, explore implementing MEV-Burn by having builders bid for block space, with a portion of their bid being burned by the protocol.
The primary goal of MEV-Burn is to transform MEV from a largely private extractive industry into a public good that benefits all token holders through deflationary pressure. By burning the extracted value, the protocol reduces the net issuance of the native token, creating a deflationary subsidy for all holders proportional to their stake. This aims to neutralize the centralizing force of MEV, as the profits are not accumulated by a few powerful players but are instead converted into a network-wide economic benefit, aligning the incentives of extractors with the long-term health of the chain.

MECHANISM OVERVIEW
Key Features & Objectives
MEV-Burn is a protocol-level mechanism that redirects a portion of the value extracted by Maximal Extractable Value (MEV) searchers back to the network, typically by destroying (burning) it, thereby reducing the net economic loss to regular users.
01
Primary Objective: Redistribute MEV
The core goal is to internalize the negative externality of MEV. Instead of value flowing entirely to block builders and validators, a portion is captured and returned to the network's economic base. This is achieved by burning the base fee from transactions in MEV bundles or via direct protocol burns, effectively making MEV less extractive and more beneficial to all token holders through deflationary pressure.
02
EIP-1559 Integration
MEV-Burn builds upon the fee market reform of EIP-1559. In Ethereum's post-merge Proof-of-Stake system, validators receive priority fees (tips), while the base fee is burned. MEV transactions generate significant base fees. By burning these fees, MEV revenue that would have gone to the miner/validator is instead permanently removed from supply, benefiting all ETH holders proportionally.
03
Economic Security & Tokenomics
By converting extracted MEV into a deflationary force, MEV-Burn enhances the network's crypto-economic security. The burned value acts as a sink, increasing the scarcity of the native token. This can:
- Improve the security budget by raising the token's value.
- Partially offset the issuance to validators.
- Align validator incentives with long-term network health over short-term extraction.
04
Implementation: Proposer-Builder Separation (PBS)
Full realization of MEV-Burn often requires Proposer-Builder Separation (PBS). PBS is a design where block builders (who construct blocks with MEV) are separate from block proposers (validators who propose blocks). This allows for a clear, enforceable mechanism where MEV profits can be identified and a portion (e.g., via an auction) can be directed to a burn address before the block is proposed.
05
Contrast with MEV-Share / MEV-Smoothing
MEV-Burn is distinct from other MEV mitigation strategies:
- MEV-Share: Aims to redistribute extracted MEV back to the users whose transactions created the opportunity.
- MEV-Smoothing: Aims to redistribute MEV equally among validators to reduce centralization risks.
- MEV-Burn: Aims to destroy a portion of MEV for the benefit of the entire token-holding ecosystem, not a specific participant group.
06
Example: Ethereum's Burn Post-Merge
Since The Merge, Ethereum's MEV-Burn is an emergent property of EIP-1559 and MEV activity. When a searcher pays a high base fee to get their arbitrage or liquidations bundle included, that base fee is burned. For instance, during periods of high MEV activity like a major DEX price swing, the burn rate can spike significantly, directly linking MEV extraction to increased deflation.
how-it-works
MECHANISM EXPLAINER
How MEV-Burn Works
MEV-Burn is a protocol-level mechanism that permanently destroys a portion of the value extracted by Maximal Extractable Value (MEV) searchers, redirecting it from validators to the network itself.
MEV-Burn is a cryptographic-economic process integrated into a blockchain's consensus layer, most notably in Ethereum's post-merge design. It functions by taking a portion of the transaction priority fees (tips) and MEV rewards that would otherwise be paid to block proposers (validators) and instead destroying or "burning" that value by sending it to an unrecoverable address. This is achieved through a specialized smart contract or a direct protocol rule, permanently removing the native token (e.g., ETH) from circulation. The primary intent is to capture and neutralize the negative externalities of MEV, transforming a potential source of centralizing economic rent into a deflationary force that benefits all token holders.
The technical implementation often relies on an auction mechanism. In Ethereum's proposed design via EIP-1559 and proposer-builder separation (PBS), block builders submit bids to validators for the right to construct a block. A portion of this bid, representing the estimated MEV, is automatically diverted to the burn address before the block is finalized. This process is enforced at the protocol level, making it trustless and mandatory. The exact amount burned is dynamically determined by market forces—the competitive bidding between searchers and builders for block space—ensuring the network captures a significant share of the total extracted value.
The economic effects of MEV-Burn are twofold. First, it acts as a deflationary pressure on the native token's supply, similar to Ethereum's base fee burn in EIP-1559, potentially increasing scarcity. Second, it reduces the profit margin for validators from MEV activities, thereby mitigating the economic incentive for validator centralization and sophisticated MEV extraction at the consensus layer. By burning this value, the benefit is socialized across the entire network of token holders rather than being captured solely by the entity that proposes a block, aligning validator incentives more closely with long-term network security and health.
A critical related concept is MEV-Smoothing, which often accompanies MEV-Burn in design discussions. While MEV-Burn destroys a portion of the extracted value, MEV-Smoothing aims to redistribute the remaining MEV rewards more evenly across all active validators, not just the lucky proposer of a high-MEV block. Together, these mechanisms work to suppress the "winner-takes-most" dynamics, reduce validator inequality, and enhance the cryptoeconomic security of the proof-of-stake network by preventing excessive rewards from concentrating on a few players.

MECHANISM
Visual Explainer: The MEV-Burn Flow
A step-by-step breakdown of how MEV-Burn redirects value from validators to the network's base fee, permanently removing it from circulation.
MEV-Burn is a protocol-level mechanism that captures a portion of the Maximum Extractable Value (MEV) generated from transaction ordering and redirects it to be burned via the network's base fee. Instead of this value being captured entirely by validators or searchers, it is sent to the block.basefee address, where the native token (e.g., ETH) is permanently destroyed. This process reduces the net issuance of the cryptocurrency, creating a deflationary pressure that benefits all token holders by increasing scarcity.
The flow begins with searchers identifying and bidding for profitable transaction orderings through a block builder. A critical component is the integration with a proposer-builder separation (PBS) framework. In this system, the winning block builder's payload is delivered to the validator (proposer). The MEV-Burn mechanism is enforced within the consensus layer: the validator must attest that the block's execution payload includes the correct amount of value to be burned, as dictated by the protocol rules.
The specific value to be burned is calculated from the priority fees and other MEV-related revenue contained in the block. This calculation is transparent and rule-based, removing discretion from individual participants. By burning this value, the protocol effectively socializes a portion of MEV profits, converting what was a private extractive rent into a public good that enhances the network's monetary policy and security budget without increasing inflation.
examples
MEV-BURN
Examples & Implementations
MEV-Burn is implemented through protocol-level mechanisms that redirect value from validators to the network itself. These examples show how it functions in practice.
01
EIP-1559 Base Fee Burn
The foundational example of value burn in Ethereum. The base fee for each transaction is algorithmically determined and permanently destroyed (burned). This mechanism:
- Removes the base fee from the block reward, reducing the extractable value for validators.
- Creates a deflationary pressure on ETH's supply.
- Is distinct from, but complementary to, the priority fee (tip) paid to validators.
02
EIP-4844 Blob Fee Burn
Extends the burn mechanism to data availability for Layer 2 rollups. Fees for posting blob-carrying transactions are burned, not paid to validators. This:
- Aligns the cost of data storage with network demand, burning value instead of paying it out.
- Reduces the proposer boost from rollup activity, a form of MEV.
- Ensures that the economic cost of blockchain bloat is borne by the network treasury (via burn) rather than becoming validator profit.
03
PBS (Proposer-Builder Separation) Integration
MEV-Burn is designed to work with Proposer-Builder Separation. In a PBS framework:
- Block builders compete to create the most valuable blocks, including MEV opportunities.
- A portion of this value is bid to the block proposer (validator).
- MEV-Burn mechanisms can be applied to this bid stream, burning a percentage of the builder's payment before it reaches the proposer, further reducing extractable value.
04
Burn as a Consensus Parameter
The burn rate is not static; it's a governable protocol parameter. This allows the network to adjust the economic policy:
- The community can vote to increase the burn percentage to further reduce validator extractable value and increase network security funding.
- It can be decreased if economic conditions require different incentives.
- This makes MEV-Burn a flexible tool for cryptoeconomic policy, directly controlled by token holders.
05
Contrast with MEV Redistribution
MEV-Burn is a specific alternative to other MEV mitigation strategies:
- Redistribution (e.g., MEV smoothing) aims to distribute extracted value among all validators.
- Burn permanently removes the value from circulation, benefiting all holders through deflationary supply and funding protocol security.
- The key difference is the destination of value: the validator set vs. the network's common treasury (destroyed supply).

security-considerations
MEV-BURN
Security & Economic Considerations
MEV-Burn is a protocol-level mechanism that destroys a portion of the value extracted by Maximal Extractable Value (MEV) searchers, redistributing it to validators and token holders.
01
Core Mechanism
MEV-Burn redirects a portion of the transaction priority fees (tips) and MEV revenue from block proposers into a burn mechanism. This is typically implemented via a proposer-builder separation (PBS) auction where builders bid for the right to construct a block. The winning bid is split: the net bid is burned, while the proposer payment goes to the validator. This transforms extracted MEV from a pure rent into a deflationary force for the native token.
02
Economic Redistribution
The system fundamentally reshapes MEV economics:
- Value Burn: The burned portion (net bid) is permanently removed from the token supply, creating deflationary pressure.
- Validator Reward: The proposer payment rewards validators for honest participation, aligning economic incentives with network security.
- Searcher Dynamics: Searchers must factor the burn cost into their bid calculations, potentially reducing the profitability of low-value or predatory MEV strategies.
03
Security & Incentive Alignment
By burning MEV, the protocol mitigates centralization risks and security threats:
- Reduces Proposer Extractable Value (PEV): Limits the outsized rewards a single validator can earn from MEV, reducing the incentive for validator centralization.
- Discourages Time-Bandit Attacks: Makes chain reorganizations less profitable by burning a key source of their potential reward.
- Protocol-Captured Value: Converts a public good problem (MEV) into a public good benefit (token deflation and security subsidization).
04
Implementation Example: EIP-1559 & PBS
On Ethereum, MEV-Burn is enabled by the combination of EIP-1559 (which burns base fees) and a Proposer-Builder Separation (PBS) design. In PBS, block builders (specialized searchers) create full blocks with MEV and submit bids to block proposers (validators). The validator selects the highest bid, and the protocol automatically burns the net bid. This design is a core component of Ethereum's roadmap post-The Merge, with the burn mechanism implemented through ePBS (enshrined PBS).
05
Impact on Tokenomics
MEV-Burn introduces a new, variable deflationary mechanism tied directly to network usage and congestion:
- Supply Shock: Burns token supply during periods of high MEV activity, acting as a counter-cyclical force.
- Fee Market Integration: Links the token's monetary policy to the fee market, making burn rate a function of demand for block space.
- Staker Yield: While burning reduces overall issuance, the proposer payments can increase staking yields for validators, potentially improving the security budget.
ecosystem-usage
MEV-BURN
Ecosystem Usage & Proposals
MEV-Burn is a proposed mechanism to redirect the value extracted by Maximal Extractable Value (MEV) from validators back to the protocol's economic security, primarily by destroying it.
01
Core Mechanism
The MEV-Burn proposal, notably for Ethereum, suggests redirecting a portion of the transaction priority fees (tips) that currently go to block proposers into a burn mechanism. This is achieved by having validators send these fees to a verifiably unspendable address or smart contract, permanently removing the ETH from circulation. The goal is to decouple validator revenue from volatile MEV, making staking yields more predictable and sustainable.
02
Economic Rationale & Benefits
Burning MEV-derived fees aims to improve Ethereum's long-term economic security and stability.
- Reduces Issuance Pressure: By burning ETH, it acts as a deflationary counterbalance to new ETH issuance to stakers.
- Decouples Security from MEV: Makes validator rewards less dependent on the opaque and potentially harmful MEV market.
- Enhances Censorship Resistance: Reduces the financial incentive for validators to adopt proposer-builder separation (PBS) schemes that could lead to centralized, censoring block-building entities.
03
EIP-1559 Synergy
MEV-Burn is a natural extension of EIP-1559, which already burns the base fee portion of transaction fees. MEV-Burn would target the remaining priority fee (tip). Together, they create a more comprehensive fee-burning mechanism where:
- Base Fee Burn: Adjusts for network congestion.
- Priority Fee Burn (MEV-Burn): Captures and neutralizes extracted MEV value. This synergy strengthens Ethereum's ultrasound money thesis by increasing the net burn rate.
04
Implementation Proposals (e.g., EIP-7266)
Concrete proposals like EIP-7266: Dev Gas and Burnable Tips outline a technical path. Key design considerations include:
- Burn Address: Using a designated, unspendable contract (e.g.,
0x00...dead). - Execution Layer vs. Consensus Layer: Determining whether the burn happens in the execution payload or is managed by the consensus layer.
- Smooth Transition: Ensuring compatibility with existing proposer-builder separation (PBS) infrastructure like mev-boost.
05
Impact on Validators & Stakers
While MEV-Burn reduces a potential revenue stream for validators, the proposal is often coupled with mechanisms to maintain staking yields.
- Consensus Layer Rewards: Staking issuance rewards would remain unchanged.
- Net Economic Benefit: The deflationary pressure from burning could increase the value of the remaining ETH, potentially offsetting lost tip revenue.
- Reduced Complexity: Validators face less operational risk from relying on volatile MEV markets.
06
Related Concepts & Context
MEV-Burn exists within a broader ecosystem of MEV mitigation and protocol economics.
- Proposer-Builder Separation (PBS): A prerequisite design that separates block building from proposing, making MEV-Burn easier to implement fairly.
- MEV-Share / MEV-Smoothing: Alternative proposals that aim to redistribute, rather than burn, MEV rewards among all stakers.
- Total Value Burned (TVB): A potential new metric, alongside Total Value Locked (TVL), to measure the deflationary effect of fee burning mechanisms.
MEV-BURN
Common Misconceptions
MEV-Burn is a mechanism to mitigate the negative externalities of Maximal Extractable Value by redirecting a portion of transaction fees to be destroyed. This section clarifies frequent misunderstandings about its purpose, mechanics, and impact.
MEV-Burn is a protocol-level mechanism that destroys a portion of the transaction fees that would otherwise be paid to validators, thereby reducing the economic incentive for harmful Maximal Extractable Value (MEV) extraction. It works by redirecting a variable base fee from each transaction into a burn address, permanently removing that ETH from circulation. This process is automated within the protocol's fee market logic, typically adjusting the burn rate based on network congestion. The primary goal is not to eliminate MEV entirely but to reduce the profitability of network-congesting, user-harming MEV strategies like time-bandit attacks or aggressive frontrunning by making the base cost of such operations more expensive and less predictable.
