Crypto Projects: “Smart Contract Bug Drained the Wallet: Is There Insurance for This?”

I audited a DeFi protocol’s smart contract. I missed a subtle re-entrancy vulnerability. Two days after launch, a hacker drained the liquidity pool of $2 million. The DAO (Decentralized Autonomous Organization) is voting to sue me.

Key Takeaways

  • Standard E&O is Useless: 99% of standard policies (Hiscox, Hartford, etc.) explicitly EXCLUDE “Cryptocurrency,” “Blockchain,” “NFTs,” and “Virtual Currency.” You have ZERO coverage with a normal policy.
  • Specialty Lines Required: You need “Digital Asset” or “Web3” specific insurance.
  • Audit Defense: These policies cover the defense costs if you are sued for a negligent audit.
  • Jurisdiction: Who sues you? A DAO isn’t a legal entity in many places, but the individual token holders can file a class action.

The “Why”: The Virtual Currency Exclusion

The Trap: Search your policy for “Virtual Currency.”
It usually says: “This policy does not apply to any claim arising out of the actual or alleged value of any virtual currency…”
Since the loss is $2M in ETH, the claim is excluded.
You need a surplus lines carrier.

The Investigation: I Quoted 3 Niche Carriers

1. Relm Insurance

  • My Analysis: Relm is the leader here. They write specific policies for Crypto Audits and Devs. They accept payment in crypto. They understand what a re-entrancy bug is.
  • The Cons: High premiums. Minimum 10k−10k− 20k per year.

2. Evertas

  • My Analysis: Focused purely on crypto risk. They inspect your GitHub repo before quoting. If your code quality is low, they won’t insure you.

3. Nexus Mutual (DeFi Cover)

  • My Analysis: This is “on-chain” insurance. You buy cover for the protocol. It pays out if there is a hack. It’s not liability insurance for you, but it protects the project.

Step-by-Step Action Plan

  1. Do Not Admit Fault Publicly: The blockchain is public, but your intent isn’t.
  2. Hire a Crypto Lawyer: Regular lawyers don’t understand DAOs.
  3. Notify Your Specialty Carrier: If you bought Relm, call them. If you have Hiscox, call them anyway (for the denial letter), then hire a lawyer.
  4. Check “Limitation of Liability”: Did your audit report say “No guarantees”?

FAQ
