Coverage for Internal Fraud (Custodial) vs Coverage for External Hacks (Non-Custodial)

Focus on Fidelity Bonds & Employee Theft: Protects against internal malfeasance, such as a rogue employee at Coinbase or Binance misappropriating funds. This is critical for regulated entities (MSBs, Trusts) that must insure client assets held in their custody. Policies often require rigorous internal audits and SOC 2 compliance.

Mandatory for Licensed Operations: Jurisdictions like New York (BitLicense) often require proof of insurance for custodial services. This model integrates with traditional financial crime insurance frameworks, covering risks like internal fraud, physical theft, and business interruption. Essential for institutions serving TradFi clients.

Smart Contract & Bridge Hack Protection: Covers users of protocols like Aave, Uniswap, or LayerZero when bugs or economic attacks drain funds. Providers like Nexus Mutual or InsurAce offer coverage for specific smart contract risks. This is vital for DeFi power users, DAO treasuries, and protocols self-insuring their contracts.

Peer-to-Pool Capital & On-Chain Claims: Coverage is backed by staked capital (e.g., NXM tokens) and claims are adjudicated via decentralized voting (e.g., Nexus Mutual's Claims Assessment). Eliminates traditional insurer counterparty risk but introduces capital efficiency and scalability challenges. Best for technically-savvy users comfortable with crypto-native processes.

Direct, predictable claims process: Coverage is triggered by a proven internal act (e.g., theft by an employee). Insurers like Lloyd's of London underwrite these policies with clear forensic requirements, leading to faster payouts for qualifying events compared to ambiguous hack investigations.

High cost & stringent requirements: Premiums for fidelity bonds can exceed 1-5% of coverage limit annually. Insurers mandate rigorous internal controls (SOC 2 audits, multi-sig policies, employee background checks), increasing operational overhead for firms like Coinbase Custody or Anchorage.

Protects against systemic external threats: Covers exploits like smart contract vulnerabilities (e.g., Nomad Bridge hack), oracle failures, or protocol logic errors. This is critical for DeFi protocols (Aave, Compound) and cross-chain bridges (LayerZero, Wormhole) holding user funds in smart contracts.

Complex attribution & coverage gaps: Determining if a loss is a 'covered hack' vs. 'market risk' is legally fraught. Most policies (e.g., from Nexus Mutual or traditional insurers) exclude governance attacks, depegs, and frontend hacks, leaving significant exposure for protocols like Curve or Balancer.

Targets insider threats: Protects against loss from rogue employees, mismanagement of private keys, or governance attacks. This matters for DAO treasuries (e.g., managing $100M+ via Safe multisigs) and institutional custodians where human/process failure is the primary risk.

Specific advantage: Risk is bounded to known entities and internal controls (e.g., multi-signature schemes like Safe, governance frameworks). Insurers like Nexus Mutual or Uno Re can audit specific processes, leading to potentially lower premiums for well-structured organizations.

Specific disadvantage: The pool of providers is small, as underwriting requires deep due diligence on each organization's internal policies. This often results in bespoke, expensive policies rather than scalable, on-demand coverage, making it less accessible for smaller protocols.

Targets protocol-layer exploits: Protects users from smart contract bugs, oracle failures, and economic attacks (e.g., flash loan exploits). This is critical for DeFi users on platforms like Aave, Compound, and liquidity providers on DEXs like Uniswap.

Specific advantage: Policies can be written for specific smart contract addresses and purchased on-demand via protocols like InsurAce or Etherisc. This creates a liquid market for risk (e.g., cover for a Curve pool) that scales with TVL, which has exceeded $1B in historical coverage written.

Specific disadvantage: Determining a "valid" hack and triggering payouts can be contentious (see the $80M Euler Finance hack and subsequent negotiations). Parametric triggers are simpler but may not cover all losses, leaving basis risk where the event occurs but the policy doesn't pay.
