Insurance in DeFi: Nexus Mutual and Beyond

 What Is DeFi Insurance?


DeFi insurance leverages blockchain technology—specifically, decentralized pools and smart contracts—to shield users from financial losses unique to the crypto space. Instead of relying on centralized insurers, users participate in peer-managed protocols. Smart contracts automatically manage premiums, claims, and payouts, all governed transparently by the community.

Nexus Mutual: A Pioneer in DeFi Insurance

What It Is:


Nexus Mutual is the most prominent protocol in the space—a decentralized mutual where members pool funds to underwrite risk collectively. Members contribute capital, become part-owners via NXM tokens, and govern the protocol.

How It Works:


Membership & Cover Purchase: Users complete KYC, buy NXM, and purchase coverage for specific smart contracts.

Staking & Risk Assessment: Members stake NXM on contracts they believe are secure. If an accepted claim occurs, staked tokens may be burned. 

Medium


Claims & Governance: Claims are evaluated and voted on by members—no automated payouts; it's discretionary mutual coverage.

If you're using Playwright for browser automation, knowing how to handle frames properly is crucial for interacting with elements inside them. In this blog, we’ll walk through how to identify, access, and interact with frames and iframes using Playwright with code examples in JavaScript and Python. 🧾 What Are Frames and Iframes? <frame>: Rarely used now; part of the outdated <frameset> HTML structure. <iframe> (inline frame): Embeds another HTML page inside the current one. Common for third-party content like ads, maps, or payment gateways. 🎯 Why Frames Matter in Automation Elements inside an iframe are not part of the main DOM, so trying to interact with them directly will result in errors unless you switch the context to the frame. 🔍 Locating an Iframe in Pla...
