Developing a DeFi Protocol Risk Assessment System
We specialize in integrating smart contract insurance for DeFi protocols. When a protocol suffers an exploit and users lose funds—audits reduce risk but don't eliminate it. Nexus Mutual, Sherlock, InsurAce, UnoRe—leading providers that cover this tail risk. Our DeFi protocol risk assessment system automates the selection and connection of such solutions, saving your team time and resources.
For a protocol, insurance integration means either built-in protection for users (the protocol buys coverage on behalf of its TVL) or allowing users to purchase individual coverage through the UI. Both options are feasible, each with different mechanics. In-built cover simplifies user experience but costs treasury; individual coverage offers flexibility but requires UI integration.
Our team has over 5 years of DeFi development experience and has successfully integrated insurance for 10+ protocols, including major projects with TVL exceeding $100M. We deliver turnkey projects—from risk analysis to launch and coverage monitoring. Contact us for a free preliminary assessment.
Why Insurance Integration Matters for Your DeFi Protocol
Without insurance, users bear the full risk of losing funds in a hack. This reduces TVL and slows growth. Integrating coverage builds trust and attracts conservative capital. Our risk assessment system evaluates your current situation and proposes the optimal insurance model.
How the Risk Assessment System Works
The system analyzes your protocol's smart contracts, incident history, TVL, and liquidity. Based on this, it selects the best coverage provider and model—embedded cover or protocol-level coverage. We automate the selection and configuration process to minimize costs and ensure uninterrupted protection.
Choosing a Coverage Provider
Nexus Mutual
Nexus Mutual is an on-chain mutual insurance company covering losses from smart contract bugs and hacks. Requires KYC for cover purchase. Cover is denominated in ETH or DAI, with a maximum size limited by pool capacity (up to 3M ETH). The claim process is governance-based: other Nexus Mutual members vote on whether the exploit was real. Subjectively, claims for real hacks (Yearn, bZx) have been paid.
Sherlock
Sherlock uses a staking model: insurers earn yield in exchange for risk. On a hack, a portion of staker capital covers losses. Sherlock performs its own audit before providing coverage, creating alignment. Claims are automatic upon confirmed exploit, payout without voting. Coverage is purchased at the TVL level, premium 2-5% TVL per year.
InsAce and UnoRe
InsurAce offers multi-chain coverage for contracts, stablecoin depegs, and bridge hacks. Premiums are lower, capacity smaller. UnoRe is a B2B reinsurance protocol.
| Provider | Coverage Type | Claim Process | Premium (% TVL/year) | Pool Capacity |
|---|---|---|---|---|
| Nexus Mutual | Mutual insurance | Governance vote | 1-3% | ~3M ETH |
| Sherlock | Staking model | Automatic | 2-5% | $50M |
| InsurAce | Multi-chain | Hybrid | 0.5-2% | $10M |
| UnoRe | Reinsurance | B2B | Individual | Dependent on partners |
Sherlock processes claims on average 3x faster than Nexus Mutual. The choice of provider depends on TVL size, transaction frequency, and acceptable premium level.
Technical Integration
Embedded Cover Purchase
We add a UI option to buy cover at deposit. The user sees: "Want to insure your deposit? Cover for 1 ETH costs 0.02 ETH/year (2% premium)."
For Nexus Mutual, we use the CoverProducts contract. The API returns available capacity and price:
const { capacity, premium } = await nexusMutual.getCoverQuote({ productId: PROTOCOL_COVER_ID, coverAmount: ethers.parseEther("1.0"), coverPeriod: 365, coverAsset: USDC_ADDRESS, }); After the quote, a buyCover transaction is sent. A Cover NFT is minted to the user's wallet.
Protocol-Level Coverage
The protocol buys cover for the entire TVL from the treasury. On a hack, the protocol files a claim, and payouts go to the treasury, then to users. This simplifies UX but requires ongoing costs (premium ~2-5% TVL/year) and a governance decision. Implementation: a multisig purchases cover via Sherlock/Nexus API. Updates when TVL grows are automated via a monitoring bot.
On-Chain Parametric Insurance
Parametric insurance pays out automatically on an on-chain event, no claim voting needed. For example: TVL drops more than 50% in one block triggers a payout. Implemented via Chainlink Automation. Downside: parameters may not match a real exploit (TVL can drop due to market moves). But savings on claim processing can reach 80%.
