Crypto Insurance Explained
What is crypto insurance, what does it cover, what it costs and how insurance alternatives like Nexus Mutual can cover/protect your crypto
Last updated: April 2026
TL;DR
"Crypto insurance" is a generic term covering protection against non-economic crypto losses, such as theft or inability to withdraw from a custodian or exchange, smart contract exploits, staking slashing, or digital asset depegs. It encompasses two distinct types of protection: traditional regulated insurance (underwritten by licensed insurers), and discretionary mutuals (such as Nexus Mutual*), which operate onchain and are not regulated. Coverage, cost and claims processes vary depending on how assets are held and who provides the protection. Protection is available from traditional insurers (custodial risk), onchain discretionary mutual providers like Nexus Mutual (protocol, depeg, and staking risk), and embedded at the protocol level (transaction risk). Costs start from ~0.12% per year for onchain cover.
"Crypto insurance" is a generic term for a broad range of financial protection designed to cover crypto losses from specific loss events. The term encompasses both traditional regulated insurance products and discretionary mutuals, which are not regulated in the same way and operate on a fundamentally different basis. Crypto insurance does not directly protect against market volatility, trading losses, or economic risk. Instead, it protects against defined risks where digital assets are lost or rendered inaccessible through no fault of the holder. What is covered, and what is excluded, depends on the provider, the product structure and how you hold your digital assets.
The crypto insurance landscape spans both traditional insurers and blockchain-native (onchain) insurance alternative providers. For example, traditional insurers such as Evertas, RELM, and Munich Re underwrite custodial and cold storage risks using conventional policy structures. Onchain providers like Nexus Mutual* use transparent mechanisms to cover smart contract and protocol-level risks that traditional insurers often can't or won't address.

Crypto insurance risk is broken down into six main risk categories (Source: Onchain Risk Map 2026). Understanding which categories apply to your assets is the first step toward evaluating whether protection makes sense and deciding which companies can provide it.
Risk categories above are sourced from The Onchain Risk Map, which is an open standard and an institutional framework to understand, categorise and navigate crypto risk. Explore the full map at onchainriskmap.com.
Custody Risk
Custody risk covers the loss of digital assets whether they are self-custodied or held by a third-party custodian.
For self-custody, the primary risks are private key theft and private key loss. Theft can happen through phishing attacks, social engineering, malware, physical theft of devices, kidnapping and ransom, or data breaches that expose stored credentials. Products like Crypto Kidnap & Ransom Cover address the physical security risks.
For third-party custody, the risks shift to the custodian. Users can lose access to assets through credential theft (phishing, SIM swaps, malware), or through custodian failure. The collapse of FTX in 2022 and the $1.5 billion Bybit exchange hack in 2025 are among the most prominent examples of custodian failures.
Dedicated insurers like Evertas and RELM underwrite custodial risk using conventional policy structures. Some custodians offer limited self-insurance or reserve funds, though these typically cover only a fraction of total deposits. Nexus Mutual also offers Custody Cover for select specific providers.
Who Custody Cover is for
DeFi users or investors using custodial solutions or exchanges.
Physical Risk
Crypto Kidnap & Ransom Cover
As crypto wealth becomes more visible, high-net-worth holders face a growing physical threat: targeted kidnapping, coercion, and forced asset transfers. These threats can bypass any technical security measure.
Nexus Mutual offers Crypto Kidnap & Ransom Cover, the first onchain product designed to address physical security risks for crypto holders. It provides a safety net for DeFi users and investors in the event that they or their loved ones are targeted.

Protocol Risk
Protocol risk is the broadest and most technically complex risk category. It entails financial losses caused by failures in the blockchain-based protocols in Decentralized Finance (DeFi).
Smart contract exploits are the most common form of protocol risk. Governance attacks exploit decentralized decision-making. Exploiting centralization weak spots, including rug pulls by operators with privileged access, are among other protocol risks.
Protocol economic risk refers to loss events stemming from misconfigured, manipulated or failed oracles as well as liquidation failures. Nexus Mutual has been the leading smart contract cover provider for protocol risk since 2019, with a wide range of products that protect against it and a verifiable history of over $18.5 million in claims paid.
Who Protocol Cover is for
DeFi users and investors with onchain allocations.
Available as Single Protocol Cover, Multi Protocol Cover, or Nexus Mutual Cover
Transaction Risk
Transaction risk is the risk of financial loss while executing a blockchain transaction. The loss occurs because the transaction doesn't reflect the user's intended action.
Protection against transaction risk is currently limited and typically embedded at the protocol level. For select protocols, transactions can be protected against technical, economic, and security risks through integrated coverage. For example, Nexus Mutual and OpenCover provide this type of embedded transaction coverage for protocols like Request Finance.
Who Transaction Cover is for
DeFi protocols that want to offer embedded coverage to their users
against transaction risk.
Digital Asset Risk
Digital asset risk covers the intrinsic risks of holding cryptocurrencies, stablecoins, and other blockchain tokens. This includes the risk of a pegged asset losing its peg or an asset having its liquidity drained.
By definition, all stablecoins are subject to depeg risks. Fiat-backed stablecoins can depeg when the underlying reserves or banking relationships are disrupted, as happened when USDC briefly depegged during the Silicon Valley Bank crisis in March 2023. Crypto-collateralized stablecoins can depeg when collateral prices swing sharply, as DAI experienced in March 2020. Algorithmic stablecoins can fail catastrophically when their stabilization mechanisms break down, as the TerraUSD collapse demonstrated in 2022.
Wrapped assets carry similar risk. When the backing or bridge infrastructure behind a wrapped token is compromised, the token can trade at a discount to its underlying asset.
Liquidity risk affects all digital assets: the risk that a token cannot be converted into cash or another asset without a significant loss in value, due to insufficient market depth or available counterparties.
Nexus Mutual provides Depeg Cover for stablecoin and wrapped asset risk, and Leveraged Liquidation Cover for investors with leveraged positions that are exposed to depeg events. Designed for institutional DeFi investors, the Leveraged Liquidation Cover covers the risk of a depeg for a leveraged position.
Who Depeg Cover is for
DeFi users and investors with exposure to stablecoins, wrapped assets, or leveraged positions vulnerable to depegs.
Staking Risk
Staking risk covers the loss of staked assets due to validator penalties, slashing events, or risks introduced by intermediary staking infrastructure.
Slashing in proof-of-stake networks (including Ethereum) penalizes validators for malicious or negligent behavior. Slashable offenses include double signing (proposing two different blocks for the same slot), surround voting (attesting to overlapping checkpoints), and double voting (voting for conflicting blocks in the same epoch). Slashing in protocol-level mechanics can impose additional penalties depending on the staking system's design.
Beyond slashing, validators face penalties for failing to perform their duties correctly, such as having downtime or missed attestations.
Liquid staking introduces intermediary risk: using protocols like Lido to stake assets means exposure to the staking protocol's own smart contract and liquidity risks on top of the underlying validator risk. During a period of market stress in 2022, stETH traded at a 6% discount to ETH.
Nexus Mutual provides slashing protection and has also expanded into related risks including depeg events for liquid staking tokens and leveraged liquidation scenarios.
Who ETH Slashing Cover is for
Institutions and investors that run ETH validators.
Systemic Risk
Systemic risk refers to the intrinsic risks of using public blockchain infrastructure itself. These are the risks that affect all participants in a network regardless of their individual security practices or coverage.
These include 51% attacks, where a group controlling the majority of a network's hash power or stake can block or reverse transactions. This category also includes consensus failures, where validator nodes fail to reach agreement and the network stalls or degrades, as well as chain forks and reorganizations, where a network permanently or temporarily splits (forks) into different versions. One famous chain fork occurred when Ethereum split into Ethereum and Ethereum Classic following the DAO hack in 2016.
Systemic risk is not currently insurable by any provider. It represents the baseline infrastructure risk that all blockchain participants accept. Understanding this risk matters because it defines the boundary of what protection products can and cannot cover. Because systemic risk is not coverable, it is not reflected in any Nexus Mutual pricing or product.
Yes, there are a variety of cryptocurrency insurance and cover options. Choosing the right option depends on the type of asset, where it's held, and the risks you're looking to cover.
If the assets are held on a regulated exchange or with a qualified custodian, some protection may already be in place. Major exchanges often maintain insurance funds or reserves to cover losses from security breaches, though these protections typically cover only a portion of total deposits and may not apply to all asset types or loss scenarios.
If the assets are self-custodied, traditional insurance generally does not cover it. Standard homeowner's or property insurance policies almost never cover digital asset losses. Specialty cold storage insurance exists, but it requires formal security assessments and is primarily available to high-net-worth individuals and institutions.
If the assets are deployed in DeFi (in lending markets, liquidity pools, vaults, or staking protocols) onchain cover is the primary form of protection. In addition to Custody, Transaction, Depeg and ETH Slashing Cover, insurance alternatives like Nexus Mutual also provide cover for protocol risks such as smart contract exploits, oracle failures, and liquidation failures. This protection is purchased, managed, and settled entirely onchain.

The cost of crypto insurance will vary depending on what you're protecting, how much coverage you need, and who is providing it.
Cost drivers
The main factors that affect pricing across all crypto protection types are: the coverage type (what risks or protocols are covered), duration (how long does the coverage apply), coverage limits (what amount is covered), security infrastructure and risk controls of the covered party, available underwriting capacity, and any special conditions attached to the cover.
Illustrative pricing scenarios
The examples below are for general information only. Actual pricing depends on individual assessment, capital availability, and other factors.
The safest way to protect your crypto is through a multi-layered approach.
The first step is to secure your keys (as they say - not your keys, not your crypto). Then ensure your wallet is only connecting to secure protocols, reduce your transaction exposure, and consider risk transfer for the residual risks you can't eliminate.
Insurance or cover is a critical layer in a broader security model, but the self-custodial nature of crypto means security starts with the individual.
Multi-layered security setup for crypto assets
Layer 1: Secure your keys
Use cold storage or multi-signature wallets for long-term holdings. Separate hot wallets (for active use) from cold wallets (for storage). Use hardware wallets from reputable manufacturers and keep firmware updated. Store recovery phrases offline in safe physical locations.
Layer 2: Harden your operations
For individuals: enable two-factor authentication on all accounts. Hardware keys are stronger than SMS or app-based 2FA. Use dedicated devices for high-value transactions.
For teams: train all team members on phishing identification and social engineering tactics. Audit third-party access to accounts regularly.
Layer 3: Reduce transaction risk
Review and revoke unnecessary token approvals. Use allowance management tools to limit smart contract permissions. Separate wallets by function (ie DeFi vs long-term storage). Simulate transactions before signing, especially for large amounts.
Layer 4: Transfer residual risk
Even after securing your keys, hardening your operations, and reducing transaction risk, there are still other risks to consider. If assets are held with custodians, verify the insurance coverage and limits. Some investors require more extensive options and look to Nexus Mutual Custody Cover.
Being on the cutting edge of DeFi means taking on some risk, so many investors consider Nexus Mutual Protocol Cover for smart contract, oracle, and liquidation risks, or Nexus Mutual Depeg Cover for stablecoin risks.

Nexus Mutual provides discretionary cover which is fundamentally different from insurance.
As the original onchain insurance alternative, Nexus Mutual wrote the whitepaper on decentralizing insurance and was the first to cover digital assets against new risks such as smart contract hacks. At the time, insurance regulators were not familiar enough with DeFi and the associated risks to issue licenses for companies to provide the necessary protection.
Instead of waiting for regulators to catch up, Nexus Mutual set out to find a solution, coalescing around one of the oldest forms of risk sharing - a discretionary mutual. This well-established structure allowed for people to pool capital and underwrite risk without needing a regulator's approval and was a perfect fit for the decentralized ethos of Ethereum.
What could have been a roadblock turned into a structural advantage for Nexus Mutual. By providing cover instead of insurance, Nexus Mutual was able to not only underwrite risks that traditional insurers wouldn't touch, it also opened a pathway for anyone to join the mutual as a capital provider or risk manager. This openness was engrained in Nexus Mutual's DNA, with the capital pool, claims history, and covers all fully transparent onchain, something no traditional insurer even comes close to.
At their core, discretionary mutuals are built on trust, which is why Nexus Mutual is proud to have a track record of paying out 100% of valid claims.
Institutional allocators who are evaluating crypto protection options need to consider several factors beyond headline coverage terms. Unlike traditional insurers where capital reserves and claims history are private, Nexus Mutual is fully transparent, displaying the capital pool size, claims history, and staking allocations verifiably onchain.
Exclusions and limitations
Every provider (traditional or onchain) maintains exclusions. Common exclusions across the market include economic losses from market movements and losses due to user error.
Counterparty and structural risk
Evaluate the financial backing of the provider. For onchain cover, review the capital pool, staking pool allocations, and claims history. Unlike traditional insurers where capital reserves and claims history are private, Nexus Mutual is fully transparent, displaying the capital pool size, claims history, and staking allocations verifiably onchain.
Claims payout and track record
How are claims assessed? How long does the payout take? What is the historical approval or litigation rate? Nexus Mutual has an expert-led claims assessment model, with known assessors and claims support. Nexus Mutual paid claims across major loss events including FTX, Euler Finance, and Stream Finance.
Composability and integration
Can the cover be embedded into existing products and workflows? Nexus Mutual's SDK enables external teams to integrate cover directly into their own products. The covered vault with Edge Capital and Kelp is an example of protection embedded at the product level.
