Restaking.risk

1. Overview

A41’s Approach to Secure Restaking-Based Security Services

Restaking.risk is a platform developed by A41 to evaluate slashing risks and incentive structures within Restaking-Secured Services(RSS). It provides stakers, researchers, and protocol developers with a standardized methodology to assess the reliability and sustainability of Actively Validated Services(AVSs).

Restaking introduces new forms of shared security in Ethereum through protocols like EigenLayer, but with this innovation comes increased complexity and variability—especially in how slashing is enforced and incentives are structured. While ELIP-002 (Slashing via Unique Stake-Operator Sets) attempts to localize slashing events and prevent cascading failures, its implementation remains optional and inconsistent across AVSs.

We believe that transparent and reliable slashing and incentive mechanisms are fundamental to building a sustainable restaking ecosystem. In this proposal, we focus specifically on proposing a standardized approach to slashing design and risk classification.

2. Classifications of Slashing Mechanism Frameworks

To provide clarity in this fragmented landscape, A41 categorizes AVS slashing mechanisms into three levels, — Deterministic, Challenge-Period, and Committee-Based with simplified decision trees — ordered by their differing reliance on automated proofs versus subjective decision-making. Each represents a different approach to penalizing misbehavior:

2.1 Deterministic Slashing

• Rules are hard-coded into the protocol or smart contract, triggering automatic penalties when specific conditions are met. This is the most trustless and immediate mechanism. There is no appeal; cryptographic evidence of a violation (such as equivocation) directly results in loss of funds and expulsion. Deterministic systems provide strong security guarantees since all validators know misbehavior will be punished swiftly and predictably. They minimize human involvement, reducing uncertainty and the potential for bias or error.

2.2 Challenge-Period Slashing

• Committee-based approaches may be used when the misbehavior is hard to detect on-chain because of the computation code or when rely on off-chain data. This mechanism balances automation with a safety valve: it’s mostly protocol-driven but acknowledges that false positives or unforeseen issues can occur, providing a remedy. The trade-off is a delay in finality and reliance on an honest reviewing party (community governance or a designated arbiter) to act if needed.

2.3 Committee-Based Slashing

• Committee-based(or governance) approaches may be used when the misbehavior is complex to detect on-chain or when social context is required. Rather than purely algorithmic triggers, human judgment or off-chain processes play a significant role. However, they introduce dependency on trust and expertise of committee members, and can become bottlenecks. Decisions might be slower and subject to politics or errors.
• To be clear, each mechanism has valid use cases. Early or experimental AVSs might start with a committee-based or ad-hoc slashing process if their failure modes are not fully understood. Some disputes truly require human judgment. Challenge-period mechanisms are common in optimistic systems (e.g. optimistic rollups or bridges) where a time window for fraud proofs is essential. Deterministic slashing works best when misbehavior can be unambiguously proven on-chain. Our framework doesn’t declare one approach universally “better” for all situations, but it does provide a yardstick for reliability: The more a slashing mechanism leans on automated, objective triggers, the more robust and predictable it is considered.

3. Problem

Restaking, enabled by protocols like EigenLayer, has introduced a new paradigm of shared security within the Ethereum ecosystem. Built on this foundation, Restaking-Secured Services (RSS)—commonly referred to as Actively Validated Services(AVSs)—operate independently while leveraging Ethereum’s security assets to perform specialized functions.

However, the expansion of this new security layer has also brought increased complexity and uncertainty. In particular, the lack of standardized information and comparison frameworks for the slashing mechanisms adopted by each AVS presents a significant risk for stakers, infrastructure providers, researchers, and protocol developers alike.

3.1 Lack of Standardization and Structural Uncertainty in Slashing Mechanisms

• In the current RSS landscape, each AVS independently designs its slashing logic. However, these designs vary widely in technical reliability and consistency, and the criteria and enforcement methods for slashing are not standardized. This structural inconsistency makes it difficult to objectively compare the risk levels between AVSs.

3.2 Poor Documentation and Limited Transparency of Slashing Policies

• Many AVSs do not provide formal documentation for their slashing policies or fail to disclose them clearly to the public. As a result, key stakeholders—including stakers, operators, and researchers—face challenges in analyzing potential risks or preparing mitigation strategies due to limited access to critical information

3.3 Reduced Interpretability Due to Diverse Slashing Models

• AVSs adopt a range of slashing mechanisms—including deterministic, challenge-period, and committee-based approaches—each differing in terms of security guarantees, automation, and decision-making authority. This diversity makes it difficult to quantitatively or qualitatively assess and compare risk across AVSs, undermining informed decision-making by stakers.

3.4 Ambiguity and Complexity in Defining Slashing Conditions

• The criteria for when and how slashing occurs vary significantly across AVSs. These conditions are often vague, overly complex, or reliant on off-chain data, subjective judgment, or committee-based decisions. Such ambiguity reduces the predictability of slashing and increases uncertainty for participants.

3.5 Absence of a Unified Framework for Slashing Risk Evaluation

• There is currently no standardized or open framework to systematically categorize slashing mechanisms and compare risk levels across AVSs. This absence of a unified evaluation structure makes it difficult for restaking participants to develop a clear and structured understanding of the security posture of each AVS, ultimately hindering transparency and trust across the ecosystem.

4. Key Features

Restaking.risk is designed to provide a structured and transparent understanding of slashing risks within the emerging landscape of Restaking-Secured Services(RSS). Its core functionality is organized around three key pillars:

4.1 Standardized Classification of Slashing Mechanisms

• Restaking.risk offers a standardized framework for categorizing the diverse slashing models adopted by Actively Validated Services(AVSs). These models—including deterministic, challenge-period, and committee-based approaches—differ significantly in automation, enforcement logic, and risk propagation potential.
• By mapping each AVS into a unified classification system, Restaking.risk enables stakeholders such as stakers and infrastructure providers to intuitively assess the suitability and maturity of the slashing mechanism in relation to each AVS’s validation model.

4.2 Refined Slashing Risk Evaluation Based on Structured Criteria

• Building on the enhanced classification of slashing mechanisms, Restaking.risk introduces a refined and evidence-based model for evaluating slashing risk. Each AVS is evaluated based on the disclosure and technical implementation of its reward and slashing policies. In particular, the slashing policy is assessed using four standardized criteria derived from metadata fields: (Detailed information about these evaluation criteria can be found on each AVS page in the restaking.risk)
• Slashing Mechanism Type
  • Whether the mechanism (deterministic, challenge-period, or committee-based) is well-aligned with the nature of the AVS’s validation task. Proper alignment is considered Low Risk (🟢), misalignment is High Risk(🔴).
• Slashing Conditions & Enforcement
  • Assesses how clearly slashing conditions are defined (e.g., on-chain, automatic, verifiable) versus how much they rely on off-chain or discretionary logic. Clearly defined, automated conditions score(🟢), ambiguous or subjective enforcement is scored(🔴).
• Verification Participation & Accessibility
  • Measures whether the verification process is open to the public or restricted to a small group. Permissionless participation is considered Low Risk(🟢), while restricted access is classified as High Risk(🔴).
• Incentive Alignment for External Verification
  • Evaluates whether the AVS incentivizes participants (e.g., challengers or committees) to engage in the verification process in challenge-period or committee-based models. Incentivized participation is (🟢), absence of incentives is (🔴).
• Using these criteria, we will assign each AVS’s task a composite Risk Level represented with the color code. To ensure consistency, we define what each level means using the following color-coded system:

Rating	Risk Level
Green (Low Risk)	Satisfies at least three out of four criteria
Yellow (Moderate Risk)	Satisfies two out of four criteria
Red (High Risk)	Satisfies one or fewer of the criteria
Grey (Not Available)	Slashing-related information has not been disclosed or is currently unavailable.

4.3 ELIP-002 Adoption Tracking and Unified Risk Dashboard

• Restaking.risk evaluates whether AVSs adopt ELIP-002 or other mechanisms that enforce slashing locality—critical for preventing cascading failures. Adoption status is visually represented to highlight systemic risk containment. Additionally, a unified risk dashboard consolidates insights from across the platform—covering slashing mechanism types, transparency scores, enforcement locality, and composite risk levels—offering restakers and ecosystem participants a holistic view of risk throughout the RSS ecosystem.

5. Reliable Data Collection and Verification Process

Evaluating the slashing systems of AVSs can be sensitive and potentially controversial. To ensure fairness and trustworthiness, it is critical to establish a transparent and collaborative rating process. We propose a GitHub-based workflow for decentralized metadata coordination and management.

5.1 AVS Metadata Repository Strategy

• Restaking.risk will implement a public GitHub repository, where each AVS maintains a structured JSON file containing key metadata fields, including:
• AVS name and description / Category (e.g., oracle, rollup, etc.) / Slashing mechanism type (deterministic, challenge, or committee) / Detailed slashing conditions and enforcement logic / Challenge period length (if applicable) / Committee composition (if applicable) / Links to documentation or code related to slashing logic / Contact information / Additional metrics (e.g., number of stakers, number of operators, etc)
• AVS teams can submit PRs to update their metadata (e.g., after deploying a new slashing contract or adjusting parameters). A small group of AVSbeat maintainers will review these PRs for accuracy and consistency, following principles of decentralized governance inspired by Cosmos. This ensures that metadata is not unilaterally controlled, but instead managed via a version-controlled and collaborative process.

5.2 Automated Validation and Manual Review

• Each metadata update PR will go through a two-layer review process
• Automated CI Checks
• Validate conformance to a predefined JSON schema
• Ensure all required fields are present and properly formatted
• Example: slashing mechanism must be one of the allowed values — “deterministic”, “challenge”, or “committee”
• Manual Maintainer Review
• Check the logical consistency and integrity of the submitted information
• Ensure alignment with Restaking.risk’s evaluation criteria

By adopting this GitHub-based data pipeline, Restaking.risk ensures that AVS metadata remains accurate, auditable, and systematically updated, thereby strengthening the credibility and reliability of its risk evaluation framework.

6. Conclusion

Restaking.risk brings clarity to the restaking ecosystem by transforming complex slashing data into structured tables and visual comparisons. It highlights critical factors such as ELIP-002 adoption, slashing mechanism types, and verification transparency, all evaluated through a standardized, color-coded framework.

By making slashing risk easier to understand and compare, Restaking.risk empowers stakers, protocols, and investors to make smarter, data-driven decisions.

In the long term, Restaking.risk contributes to the development of a more secure, transparent, and resilient restaking infrastructure, where risk visibility is no longer optional, but essential.
