Digital asset and Web3 insurance
Digital asset and Web3 insurance protects your startup during enterprise deals, exchange onboarding, and digital-asset incidents that threaten growth.
Enterprise buyers, custodians, and exchange partners now require insurance protection before approving a vendor or integration. A bridge exploit, wallet compromise, 51% attack, or vampire attack can stop a deal before signature. RiskCube secures crypto-native coverage through Web3-specialty carriers.
What a claim looks like
A Web3 infrastructure company suffers a 51% attack on a blockchain for which it operates a bridge for. Attackers double-spend approximately $1.2M during the attack window. Enterprise clients using the bridge file SLA reimbursement demands totaling $300K. Forensic investigation, restoration, and legal defense add another $400K.
Without insurance
The startup absorbs $1.9M+ in losses, fights client reimbursement demands alone, and rebuilds bridge infrastructure out of operating capital.
With RiskCube
The Web3 policy responds to 51% attack-related business income loss and restoration expenses, digital-asset theft from compromised settlement infrastructure, third-party SLA dispute defense, and forensic and incident-response. This minimizes the out-of-pocket expense for the Web3 startup.
Digital asset and Web3 risks
1. Regulatory, compliance, and governance risk
Crypto and Web3 companies often operate across payments, stablecoins, trading, custody, DeFi, tokenized assets, DAOs, and cross-border money movement. This places them close to financial-services regulation, particularly around securities, payments, AML/KYC obligations, custody requirements, and consumer protection rules. The consequence can include investigations, fines, operational halts, blocked banking relationships, investor disputes, or claims against directors and officers. RiskCube can help through D&O, regulatory defense, investigation-cost coverage, governance liability protection, and claims support where legally insurable.
2. Custody, wallet, private-key, and cyber theft risk
Many crypto companies touch wallets, wallet funding, self-custody, treasury, exchanges, payments, stablecoins, or digital-asset movement, making private keys and transaction authorization critical points of failure. The consequence of a wallet hack, private-key compromise, phishing attack, or fraudulent instruction can be immediate loss of assets, customer claims, business interruption, and reputational damage. RiskCube can help cover cybercrime, digital-wallet theft, electronic fraudulent instruction, forensic response, and recovery costs, and related claims where the policy responds.
3. Smart contract, protocol, tokenization, and Web3 E&O risk
Many Web3 companies depend on protocols, smart contracts, tokenization, staking, DApps, account abstraction, DeFi, blockchain data, or Web3 infrastructure. The consequence of a coding error, flawed protocol design, failed token minting process, insecure DApp configuration, or incorrect staking logic can be user loss, stalled transactions, legal disputes, and negligence claims. Insurance can help through Web3 E&O or professional-liability coverage for wrongful acts, errors, and omissions in Web3 services.
4. Stablecoin, liquidity, yield, market, and trading-loss risk
Many Web3 and crypto companies focus on stablecoin payments, global dollar accounts, FX liquidity, perps, memecoins, derivatives, automated investing, treasury, and yield products. The consequence can be customer losses from depegging, liquidity shortages, failed redemptions, inaccurate yield representations, trading disputes, margin losses, or market-stress events. Insurance can help cover certain professional liability claims, misrepresentation claims, defense costs, investigation expenses, and platform-failure liabilities where the policy responds.
5. Network, Layer-2, bridge, consensus, and business interruption risk
Many Web3 companies depend on blockchains, bridges, Layer-2s, sidechains, data availability, RPC/indexing infrastructure, validators, or consensus mechanisms outside their direct control. The consequences of a bridge exploit, Layer-2 vulnerability, chain halt, fork, 51% attack, or indexing/RPC outage can be stolen funds, downtime, failed transactions, revenue loss, and customer churn. RiskCube can help through business interruption, restoration costs, business continuity expenses, investigation costs, and blockchain-specific event coverage.
6. 51% attacks and consensus failures
A malicious party gains majority control of a blockchain's consensus power, enabling double-spending, transaction reversal, or network halts. Real cases include Ethereum Classic 2019 ($1M+ losses) and Bitcoin Gold 2018. Specialty Web3 policies reimburse business income loss and restoration expenses—a clause not found in standard cyber or Tech E&O.
7. Vampire attacks and liquidity migration
A rival project incentivizes users or liquidity away from your platform via token rewards, airdrops, or forked features (SushiSwap vs. Uniswap, 2020; LooksRare vs. OpenSea, 2022). Specialty Web3 policies reimburse legal and investigative costs from vampire attack events—coverage that doesn't exist in any generic cyber or Tech E&O policy.
The exclusion problem for Web3 startups
Traditional insurance is written for conventional software companies. You manage digital assets, custody exposure, validator infrastructure, and smart-contract risk.
The specific exclusions to watch for in generic Tech E&O and cyber policies:
- Smart-contract exploits excluded from standard Tech E&O.
- Digital-asset theft excluded, sublimited, or not recognized as money or securities.
- 51% attacks, vampire attacks, consensus failures unnamed and therefore unaddressed.
- Tokens and digital assets not recognized as "money" or "securities" in generic definitions.
- Cryptojacking typically excluded as "unauthorized use of resources".
Who needs it?
Crypto infrastructure providers
RPC providers, indexers, validators, oracle services, MEV infrastructure.
Stablecoin issuers and payment rails
On/off-ramps, payment infrastructure, custody.
DeFi protocols
Liquidity pools, smart contracts, treasury management, staking infrastructure. Post-exploit decisions about pausing, forking, or socializing losses create personal fiduciary exposure for founders.
AI × crypto teams
Agent-based trading, on-chain agents, AI-driven compliance tools.
Crypto custodians and exchanges
Wallet infrastructure, institutional asset custody.
Token issuers and DAOs
Stablecoin issuers, security token platforms, governance tokens. Securities-classification disputes and DAO-promoter liability expose founders personally—D&O is investor-required at Seed or Series A.
If your business runs on-chain, holds digital assets in any meaningful way, or sells into an enterprise customer that asks about custody—RiskCube can place coverage for you.

FAQs About Web3 Startup Insurance
Is Web3 insurance different from traditional insurance?
Yes. Traditional insurance was written for conventional software companies and corporate networks. It doesn't address smart-contract exploits, private-key compromise, DAO governance exposure, validator failures, 51% attacks, vampire attacks, or evolving crypto regulation. Web3 insurance solutions, sometimes called digital asset insurance, do. RiskCube helps Web3 companies access crypto-native coverage through Web3-specialty carriers who write these risks affirmatively into the policy.
Does Web3 insurance cover smart-contract hacks?
Sometimes. Smart-contract exposure is covered by specialty Web3 carriers if your contracts are audited and your architecture meets underwriting criteria. Generic tech and cyber policies almost always exclude smart-contract exploits, unaudited contracts, protocol failures, and token-related events. Web3 policies through RiskCube, for example, include affirmative coverage for smart-contract wrongful acts as a standard insuring clause.
What is a 51% attack and is it covered?
A 51% attack occurs when a malicious party controls more than 50% of a blockchain network's consensus power, enabling double-spending, transaction reversal, or network halts. Specialty Web3 policies (through RiskCube) reimburse business income loss and restoration expenses during the restoration period. Generic policies don't name this peril and typically won't cover it.
What is a vampire attack and is it covered?
A vampire attack is when a rival project incentivizes users or liquidity away from your platform via token rewards or forked features (SushiSwap vs. Uniswap, 2020; LooksRare vs. OpenSea, 2022). Specialty Web3 policies reimburse legal and investigative costs from vampire attack events. No generic policy covers this.
Can I insure cross-chain bridge risks?
Yes, though underwriting scrutiny is higher. Carriers review bridge architecture, audit history, transaction controls, validator design, liquidity exposure, and past exploit history before quoting.
What happens if a DeFi protocol is hacked?
A DeFi exploit can result in liquidity loss, frozen withdrawals, investor allegations, emergency forensic costs, and regulatory scrutiny. Specialty cyber, crime, and Tech E&O policies can respond, but coverage depends on custody structure, wallet controls, smart-contract audits, and policy wording. Generic policies typically exclude smart-contract exploits entirely.
Who decides if a claim is valid in decentralized insurance?
Web3 insurance solutions from RiskCube are regulated and top-rated insurance—meaning the carrier's claims team, forensic investigators, and policy wording determine whether a claim is covered. This is different from on-chain "decentralized insurance" protocols where token-holder voting can adjudicate. Both models exist. RiskCube places regulated coverage.
How fast can I get covered?
Most Web3 startups get quotes within 24 hours of completing the intake form. After binding, you receive your COI. RiskCube helps reduce the delays common with traditional brokers.
