Professional Liability Insurance
Professional liability (errors & omissions) covers claims that your professional services were negligent, late, or failed to deliver — the failure-to-perform exposure for web3 dev shops, advisors, and consultancies.
Professional Liability for Web3 Services
If you build, advise, or consult for other crypto projects, professional liability protects you when a client alleges your work was negligent, incomplete, or failed to deliver the promised result. For a web3 development shop that's a protocol delivered late or off-spec; for an advisory or tokenomics consultancy it's guidance a client claims led to a loss.
These are economic-loss claims — financial harm rather than bodily injury or property damage — which is exactly why general liability won't respond. Even a baseless claim can cost significant sums to defend, and a single disputed engagement can generate a claim far larger than the fee. Professional liability funds the defense and pays covered damages.
Often Combined with Tech E&O
For firms that both build software and provide services, professional liability is usually delivered as part of a technology E&O policy. Pure advisory and consulting firms may carry it standalone (miscellaneous professional liability). We structure it to match how your firm actually earns revenue and to satisfy the insurance and indemnification clauses in your client contracts.
What's Covered
Frequently Asked Questions
Professional liability covers claims that your services were negligent or failed to deliver — a client-relationship dispute. Smart-contract liability covers on-chain exploits and code failures that cause fund loss. A web3 dev shop building for clients often needs both.
Yes — independent advisors and developers face the same failure-to-deliver and negligence claims as larger firms, and clients increasingly require proof of E&O before signing. A single disputed engagement can produce a claim that dwarfs the fee.
