An MCR claim refers to the claims process within on-chain mutual insurance protocols.
This process is specific to decentralized mutual insurance platforms that adopt the Minimum Capital Requirement (MCR) model. After purchasing risk coverage, users can submit a claim if a covered event occurs. The MCR functions as the "safety threshold" of the capital pool, ensuring that even after claims are paid, the fund remains sufficiently robust. It determines whether a payout can occur, the payout amount, and whether limitations or delays are necessary.
Projects that utilize the MCR model typically display their MCR percentage (MCR%), which represents the fund’s capital adequacy ratio. When claims are processed, the capital pool balance decreases, affecting the MCR%. This, in turn, impacts new policy issuance and premium rates.
It directly affects your ability to receive payouts, the payout amount, and the expected settlement timeframe.
Understanding MCR claims helps you assess the real payout capacity of on-chain insurance. A higher MCR% provides a stronger safety buffer, enabling the fund to withstand multiple claims simultaneously. Conversely, when the MCR% approaches its threshold, projects may raise premiums, lower coverage limits, or temporarily suspend new policies.
For both investors and policyholders, monitoring the MCR% and claims policies allows for a more accurate risk and return assessment, helping you avoid focusing only on “annual yield” or “coverage amount” without considering actual payout feasibility.
The typical process involves several stages: purchasing coverage, event occurrence, claim submission, review, and payout.
To summarize: The MCR does not replace policy terms—it constrains fund sufficiency. Policy terms determine "whether a payout is owed," while the MCR dictates "how much can be paid and how quickly."
MCR claims are common in DeFi and cross-chain insurance products. Claims affect the pool’s MCR%, influencing premiums and coverage capacity.
For smart contract risk coverage: If a protocol is hacked, all users who purchased coverage submit claims. Approved cases receive payouts (lump-sum or in installments), reducing pool balances and lowering MCR%. Projects may raise premiums or pause new policies in response.
For cross-chain bridge risks: If bridge contracts or validators fail, resulting in asset losses, claims may involve complex evidence (e.g., cross-chain transaction records or price deviations of pegged assets). MCR pressure is higher due to potentially large losses from single incidents.
For account security risks: Some mutual insurance products cover personal wallet or centralized exchange account hacks. Note: Trading tokens related to such protocols (e.g., governance tokens) on Gate exposes you to price risk but does not equate to active coverage. Actual claims must be submitted and tracked via the protocol’s official DApp.
Key steps include reading terms beforehand, preserving evidence during incidents, and following claim procedures afterward.
In 2025, most claims concentrated on smart contract exploits, cross-chain bridge incidents, and account security breaches—with individual payouts typically ranging from hundreds of thousands to several million USD.
According to public dashboards (e.g., some mutual insurance [dashboards], Q3 2024 data), total claim events decreased compared to the previous year. However, a few large-scale incidents accounted for a higher share of payouts, causing temporary MCR% dips during those events. By 2025, most projects maintained MCR% in safe ranges; new policies were issued more cautiously and premiums for high-risk protocols were increased.
Drivers behind these trends include: wider adoption of DeFi audits and bug bounties reduced frequent small-scale incidents; however, systemic risks in cross-chain bridges and complex derivatives persist—when they occur, single-event losses are substantial, putting significant stress on MCR levels. Before purchasing coverage, check the latest project data for MCR%, pool balance, recent claim records, and rely on official updates (such as Q2/Q3 2025 reports).
The main difference lies in transparency over capital adequacy and decision-making—MCR constraints are more direct.
Traditional insurance relies on company balance sheets and internal risk management; claim decisions are made by the insurer and cannot be easily verified on-chain. With MCR claims, capital pool balances, MCR%, claim votes, and payments are all trackable on-chain—allowing the community to assess underwriting capacity in real time.
Also, traditional insurance capital requirements are set by regulators and payouts come from company cash flows. On-chain mutual insurance relies on protocol-managed capital pools; MCR acts as an endogenous constraint—batch limits or installment payments may be used during mass claims events. For users, submitting an on-chain claim requires providing blockchain-based evidence within specified block-time windows; once approved, payouts tend to be faster and more verifiable than with traditional insurers.
MCR claims are automated via smart contracts with no need for manual review—payouts often complete within hours. Traditional insurance requires paperwork submission, human review, and decision-making that can take weeks. Blockchain transparency makes every step of the MCR claim process auditable in real time, building greater trust.
Common reasons include failure to meet triggering conditions (such as protocol-defined thresholds), incomplete supporting documents, or abnormal/delayed on-chain data. Check the specific smart contract trigger mechanisms to ensure compliance with protocol rules; platforms like Gate provide detailed error logs for further troubleshooting.
Submitting an MCR claim itself usually incurs no extra fees; however, you must pay gas fees (network transaction costs) when filing on-chain. Gas fees fluctuate based on network congestion—submitting during off-peak times can reduce costs. Fee structures may vary by platform; consult Gate support for details.
Payout limits depend on both insurance fund size and protocol design—most set per-claim caps as well as annual aggregate limits. These limits vary by protocol; read contract terms carefully before participating. If your claim exceeds available funds, it may be queued for future payout.
Evaluate trustworthiness using three criteria: 1) Are audit reports and contract code open and transparent? 2) Is the insurance fund managed by independent custodians with traceable assets? 3) Does the platform have a track record of successful payouts? Choosing rigorously vetted protocols through reputable platforms like Gate reduces risk.
