MEV Burn is a cryptoeconomic mechanism designed to capture and permanently remove (or "burn") a significant portion of the profits generated by Maximal Extractable Value (MEV) activities on a blockchain. Instead of this value accruing entirely to validators or block proposers through transaction ordering, the protocol automatically redirects it to be destroyed, creating a deflationary pressure on the network's native token. This process is typically implemented by sending the proceeds from priority fees or specific MEV-related auctions to an unrecoverable address, effectively reducing the token's total supply.

What is MEV Burn?
MEV Burn is a protocol-level mechanism that destroys a portion of the value extracted by Maximal Extractable Value (MEV) searchers, redirecting it from network validators to the protocol's native token holders.
The primary objectives of MEV Burn are to enhance protocol sustainability and improve user fairness. By burning MEV revenue, the protocol captures value for the collective ecosystem rather than allowing it to be extracted by a specialized class of actors. This can help offset blockchain issuance (inflation), benefiting all token holders proportionally. Furthermore, it aims to disincentivize excessive and potentially harmful forms of MEV extraction, such as sandwich attacks, by reducing the economic reward for such strategies and aligning validator incentives with network health.
A canonical implementation is EIP-1559 on Ethereum, which burns the base fee portion of transaction fees. While not exclusively an MEV Burn, it captures a foundational component of transaction fee markets. A more direct example is the proposer-builder separation (PBS) design with an integrated burn mechanism, where builders bid for block space in an auction and a portion of their bid is sent to the burn address. This ensures the value from advanced block construction is partially returned to the ecosystem.
The economic impact of MEV Burn is twofold: it acts as a deflationary force on the native asset's supply and redistributes wealth from active extractors to passive holders. This can make the token more capital-efficient as a store of value. However, its effectiveness depends on the design's ability to capture a meaningful share of total MEV without compromising blockchain security; validators must still receive sufficient rewards to justify their staking and operational costs.
Implementing MEV Burn requires careful protocol design to avoid unintended consequences. If too much value is burned, it could undermine validator incentives and network security. Protocols must balance the burn rate with staking yields to ensure the Proof-of-Stake (PoS) system remains robust. Furthermore, the mechanism must be resistant to manipulation, ensuring searchers and builders cannot easily bypass the burn through off-chain agreements or other obfuscation techniques.
key-features
MECHANISM
Key Features of MEV Burn
MEV Burn is a protocol-level mechanism that redirects value extracted from transaction ordering back to the network's native asset holders, fundamentally altering the economics of block production.
01
Value Redirection
MEV Burn captures a portion of the Maximum Extractable Value (MEV) that would otherwise be claimed by validators or searchers and permanently destroys it. This is typically achieved by redirecting transaction priority fees or a share of the block's total MEV into a burn address, reducing the net supply of the native token (e.g., ETH).
02
Protocol-Enforced
The burn mechanism is enforced at the consensus layer or execution layer protocol rules, not by individual validators. This ensures compliance and makes the burn a predictable, non-optional part of the block validation process. It is often implemented via an EIP (Ethereum Improvement Proposal), such as EIP-1559's base fee burn, which was a precursor to broader MEV burn concepts.
03
Economic Security & Tokenomics
By burning MEV-derived value, the protocol increases the scarcity of the native token, creating a deflationary pressure that benefits all holders. This transforms MEV from a potential security risk (incentivizing chain reorgs or centralization) into a network benefit, aligning validator rewards more closely with the long-term health of the chain.
04
Post-Proposer-Builder Separation (PBS)
Full MEV Burn is designed to work in conjunction with Proposer-Builder Separation (PBS). In a PBS model, block builders compete to create the most profitable blocks, and proposers (validators) simply select the highest-paying header. MEV Burn can be applied to the builder's payment, ensuring the surplus value beyond the proposer's reward is returned to the protocol treasury or burned.
05
Contrast with MEV Redistribution
MEV Burn is distinct from MEV redistribution or MEV smoothing mechanisms. While redistribution aims to share MEV profits more evenly among validators (e.g., via a block reward auction), burning destroys the value entirely. The primary goal of burning is protocol-owned value and tokenomics, not fairness in validator payouts.
06
Example: Ethereum's EIP-1559 & Future PBS
- EIP-1559: Burns the base fee from every transaction, a form of predictable, non-MEV burn.
- PBS with Burn: Proposed designs (like ePBS) include a burn address as a bid recipient. Builders submit bids to this address, and the highest bid is burned, with the proposer receiving a standardized reward. This captures volatile MEV for the network.

MECHANISM
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) activities, redirecting it from validators and searchers back to the network's economic security.
MEV Burn is a cryptoeconomic mechanism implemented in a blockchain's protocol to capture and destroy a portion of the value generated by Maximal Extractable Value (MEV) activities. Instead of this value being captured entirely by validators and searchers, it is redirected to a burn address, permanently removing it from circulation. This process is analogous to a network-wide transaction fee burn, but it specifically targets the often-opaque profits from MEV strategies like arbitrage, liquidations, and sandwich attacks. The primary goals are to redistribute the economic benefits of MEV, reduce the incentive for excessive and potentially destabilizing MEV extraction, and enhance the overall security and fairness of the network.
The technical implementation typically involves modifying the block proposer and fee market logic. When a validator includes transactions in a block that generate MEV—such as profitable arbitrage trades—a predefined percentage of that extracted value is automatically calculated by the protocol. This value, often derived from priority fees or direct profit measurement, is then sent to an unspendable address (e.g., 0x000...), effectively burning it. This reduces the net profit for the block proposer and the searchers whose transactions created the opportunity. Protocols like Ethereum implement MEV Burn through upgrades like EIP-1559 extensions, where a portion of the priority fee from MEV-heavy blocks is burned.
The economic effects of MEV Burn are multifaceted. By burning MEV-derived value, the mechanism acts as a deflationary pressure on the native token's supply, potentially benefiting all token holders through scarcity. It also disincentivizes the most aggressive and network-congesting forms of MEV extraction by lowering their profitability, which can lead to a more stable base fee and improved user experience. Furthermore, it addresses the centralization risks associated with MEV, where large, sophisticated players could dominate extraction, by reducing the absolute rewards available and making validator rewards more uniform.
MEV Burn is often discussed in conjunction with MEV Smoothing or MEV Redistribution proposals. While MEV Burn destroys the value, smoothing mechanisms aim to redistribute MEV profits more evenly among all validators over time, not just the proposer of a specific lucrative block. A hybrid approach is possible, where some MEV is burned and the remainder is smoothed. The specific design choices—what percentage to burn, how to measure the MEV profit accurately, and how to integrate with existing consensus and execution layers—are active areas of protocol research and development within ecosystems like Ethereum.
primary-motivations
CORE RATIONALE
Primary Motivations for MEV Burn
MEV Burn is a proposed protocol-level mechanism designed to address systemic issues in blockchain transaction ordering. Its implementation is driven by several key economic and security objectives.
01
Redistribute Extracted Value
The primary goal is to recapture value that would otherwise be extracted by searchers and validators/proposers through MEV (Maximal Extractable Value). By burning a portion of this value (e.g., via a portion of priority fees), the protocol redirects it to benefit all network participants through deflationary pressure on the native token, rather than concentrating it among a few sophisticated actors.
02
Improve Network Security
MEV Burn aims to strengthen consensus security by reducing the financial incentive for proposer centralization. High MEV rewards can lead to the formation of dominant validator pools or cartels. By burning this excess value, the protocol diminishes the profit motive for such centralization, promoting a more decentralized and resilient validator set. This aligns long-term security with the protocol's health.
03
Enhance User Experience
By reducing the profitability of certain adversarial MEV strategies (like time-bandit attacks or excessive sandwich attacks), MEV Burn can lead to a fairer and more predictable transaction environment for end users. This results in:
- More consistent transaction inclusion times.
- Reduced gas price volatility caused by bidding wars.
- A lower likelihood of users being negatively impacted by predatory trading bots.
04
Create Predictable Tokenomics
MEV Burn introduces a deflationary mechanism tied directly to network usage. As transaction activity and MEV opportunities increase, so does the burn rate. This creates a sustainable, usage-driven economic model that:
- Provides a counterbalance to token issuance (staking rewards).
- Offers a verifiable value accrual mechanism for the native asset.
- Aligns the token's scarcity with the economic activity it secures.
05
Mitigate Consensus Risks
Large, unpredictable MEV rewards can introduce consensus instability. Validators may be incentivized to perform reorgs or deviate from honest protocol behavior to capture outsized rewards. Burning MEV reduces the size of these irregular, lottery-like payouts, making validator rewards more consistent and predictable. This lowers the risk of attacks that could compromise the finality and liveness of the chain.
06
Align with Protocol Sustainability
MEV Burn is viewed as a long-term solution for protocol-owned value. Instead of value leaking to external extractors, it is programmatically removed from circulation, benefiting all token holders proportionally. This approach is seen as more sustainable and equitable than alternative designs that might attempt to redistribute MEV through complex social consensus or treasury mechanisms, which can be difficult to govern.

MEV BURN
Ecosystem Usage & Implementations
MEV Burn is a protocol-level mechanism that redirects value extracted by Maximal Extractable Value (MEV) activities back to the network's base layer, typically by destroying (burning) it. This section details its key implementations and ecosystem impact.
01
EIP-1559 Integration
The primary implementation of MEV Burn is through EIP-1559, where a portion of transaction fees (the base fee) is burned. Validators and block builders can still earn priority fees (tips), but the core network value from congestion is permanently removed from circulation. This mechanism directly ties network usage to deflationary pressure on the native token's supply.
02
Proposer-Builder Separation (PBS)
MEV Burn is often discussed in the context of Proposer-Builder Separation (PBS). In a PBS design, specialized block builders compete to create the most profitable block, paying the block proposer (validator) for inclusion. MEV Burn protocols can be designed to capture a portion of this builder revenue and burn it, rather than letting it accrue solely to the proposer, thereby socializing a share of the MEV.
03
Burn Auctions (e.g., Ethereum)
Some designs propose a burn auction mechanism. Here, block builders bid for the right to build a block by committing to burn a certain amount of the native token. The highest burn bid wins, directly converting MEV profits into a deflationary force. This creates a competitive market where MEV revenue is efficiently transferred to benefit all token holders via supply reduction.
04
MEV Redistribution & Social Welfare
Beyond simple burning, MEV Burn is a form of MEV redistribution. It addresses the negative externalities of MEV by capturing value that would otherwise be extracted by searchers and validators and returning it to the collective stakeholder base. This can improve network security (by reducing the incentive for validator centralization around MEV) and enhance user experience by disincentivizing predatory transaction ordering.
05
Implementation Challenges
Key challenges in implementing MEV Burn include:
- Enforceability: Ensuring builders comply with burn rules in a trustless manner, often requiring cryptographic commitments.
- MEV Leakage: Preventing value from being extracted via off-chain, non-burnable channels (e.g., off-chain agreements).
- Complexity: Adding another layer to the already complex block production market, potentially requiring consensus-level changes.
06
Ethereum's Path (PBS with MEV Burn)
Ethereum's roadmap, post-The Merge, includes enshrined PBS with integrated MEV Burn as a potential future upgrade. The goal is to create a credibly neutral, protocol-native solution that mitigates MEV's centralizing risks and captures its value for the ecosystem. This represents a major evolution from the current mev-boost middleware model used by Ethereum validators.
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 instead of solely to block producers.
01
Core Mechanism
MEV Burn redirects transaction priority fees (tips) from MEV searchers' bundles into the network's fee market. A portion of these fees is permanently destroyed (burned) rather than being paid to the block proposer. This is often implemented by modifying the block builder and proposer-builder separation (PBS) dynamics to capture this value at the protocol level.
02
Primary Economic Goal
The main objective is to recapture economic value for the native token and its holders. By burning MEV-derived fees, the mechanism:
- Creates a deflationary pressure on the token supply.
- Reduces the validator/MEV cartel problem by limiting outsized profits to a few entities.
- Aligns network security incentives by making the base token more valuable, which benefits all stakers.
03
Security Implications
MEV Burn aims to improve network security by mitigating centralization risks:
- Reduces Proposer Extractable Value (PEV): By burning a share of MEV, it decreases the financial incentive for validators to collude or manipulate the block auction process.
- Deters Time-Bandit Attacks: Lower potential rewards make reorganizing the chain for MEV less profitable.
- Promotes Fairer Sequencing: While not eliminating MEV, it reduces the economic power of dominant block builders.
04
Implementation Example: EIP-1559 & Beyond
Ethereum's EIP-1559 introduced a base fee that is burned, capturing some MEV from simple transactions. Proposer-Builder Separation (PBS) with an in-protocol MEV burn is a proposed extension. In this design, builders bid for block space in an auction, and a portion of their winning bid is burned, directly capturing complex MEV.
05
Criticisms & Trade-offs
MEV Burn involves key design trade-offs:
- Builder Incentives: If too much value is burned, it may disincentivize sophisticated builders, reducing block efficiency.
- Complexity: Requires careful protocol design (like enforced PBS) to avoid manipulation.
- Incomplete Solution: It addresses the distribution of MEV profits but does not eliminate the underlying MEV opportunities themselves, which can still cause user harm.
06
Related Concepts
Understanding MEV Burn requires familiarity with:
- Maximal Extractable Value (MEV): The total value that can be extracted from block production beyond standard block rewards.
- Proposer-Builder Separation (PBS): A design that separates the roles of block building and proposing to mitigate centralization.
- EIP-1559: Ethereum's fee market change that burns a base fee, a precursor to more direct MEV burn mechanisms.

MECHANICAL SYNERGY
Relationship with EIP-1559 and Base Fee Burn
MEV Burn is a proposed mechanism that builds upon the foundational fee market reforms introduced by EIP-1559, aiming to capture and destroy the value extracted by Maximal Extractable Value (MEV).
The MEV Burn proposal is a direct conceptual and mechanical extension of EIP-1559. While EIP-1559 introduced the base fee—a dynamically adjusting, network-burned fee for basic block space—it did not address the value from transaction ordering, known as MEV. MEV Burn seeks to apply a similar "burn" principle to this separate economic layer. It proposes to capture a portion of the profits that validators earn from MEV activities, such as arbitrage and liquidations, and permanently remove them from circulation, similar to how the base fee is destroyed.
Mechanically, EIP-1559's base fee burn and MEV Burn target different revenue streams for validators. The base fee is paid by all users for inclusion and is burned automatically. MEV revenue, however, comes from sophisticated strategies within the block. Proposals like PBS (Proposer-Builder Separation) are often seen as prerequisites for MEV Burn, as they create a clear market where builders bid for block space. MEV Burn would then tax these bids or the resulting profits, with the proceeds sent to the burn address. This creates a dual-burn system: one for generic congestion (EIP-1559) and one for economic ordering rents (MEV Burn).
The combined effect aims to enhance Ethereum's economic security and fairness. By burning both the base fee and a significant portion of MEV, the overall ETH issuance is reduced more aggressively, increasing the deflationary pressure on the network's native asset. Furthermore, it democratizes the value of MEV by redistributing it to all ETH holders through supply reduction, rather than concentrating it solely with block proposers. This addresses a key criticism of MEV—that it represents a form of value extraction that undermines the network's credibly neutral ethos.
FAQ
Common Misconceptions About MEV Burn
MEV Burn is a core mechanism in Ethereum's post-merge economics, but its function and impact are often misunderstood. This section clarifies the most frequent points of confusion.
No, MEV Burn does not eliminate MEV; it only burns the portion of MEV revenue that validators capture as priority fees. MEV, or Maximal Extractable Value, arises from the ability to reorder, include, or censor transactions within a block. The MEV Burn mechanism, introduced in EIP-1559 and enhanced by proposer-builder separation (PBS), specifically targets the priority fee (tip) that block proposers receive. The underlying arbitrage, liquidations, and other value extraction opportunities that create MEV still exist and are captured by searchers and builders. The burn simply redirects a significant portion of the proceeds that would have gone to the validator to the network itself, reducing the net profitability of MEV extraction without removing its source.
MEV BURN
Frequently Asked Questions (FAQ)
Answers to common technical questions about MEV Burn, its implementation, and its impact on blockchain economics.
MEV Burn is a protocol-level mechanism that destroys, or 'burns,' a portion of the value extracted by Maximal Extractable Value (MEV) transactions, permanently removing it from the token supply. It works by redirecting a percentage of the profits from activities like arbitrage and liquidations—typically captured by searchers and validators—into a burn address instead. For example, on Ethereum, a portion of the priority fees from MEV-related blocks proposed via mev-boost is automatically burned. This process reduces net issuance, creates deflationary pressure, and aims to return a share of the MEV value to all token holders rather than a select few.
