We’ve been working with @pwndao for a while, and they’re doing something truly impactful in DeFi. Today we want to take a moment to break down why we think PWN is a game-changer for peer-to-peer lending. PWN is all about trustless P2P lending. Instead of relying on intermediaries or centralized platforms, borrowers and lenders connect directly. It’s DeFi as it was meant to be: decentralized and permissionless. 💡 🔎Here’s how it works: 👉Borrowers lock up NFTs, tokens, or other assets as collateral. 👉Lenders provide loans directly based on that collateral. The terms are fully customizable—interest rates, duration, and repayment. Smart contracts ensure everything runs smoothly and securely. 🔒 ❓What makes PWN special? ✅Accessibility: Any asset can be used as collateral, from DeFi tokens to NFTs. ✅Flexibility: Borrowers and lenders set their own terms. ✅Trustless: No middlemen. Just code securing the deal. It’s a DeFi-first approach to lending. In a world where many DeFi platforms feel like traditional finance with extra steps, PWN is bringing back true decentralization—and solving real problems like: Unlocking liquidity from underused assets (like NFTs). Giving lenders more control over their risk. What could you do if your NFTs, tokens, or other assets didn’t just sit idle? PWN unlocks their potential, turning them into collateral for trustless loans. If you haven’t explored PWN yet, now’s the time. They’re pushing DeFi lending forward. 🚀

🎆 2024 in review: Read the full story here: extropy-io.medium.com/2024-in-review… This year, Extropy was on the move, bringing blockchain security and ZK knowledge to the world. 23 events in 18 cities across the globe, from Bangkok to Berlin, Lisbon to London. We spoke, hacked, and collaborated at summits, hackathons, and meetups. 🌍 15+ courses taught, from Cairo security to MEV bots, zkML, Solana, Solidity and more—helping hundreds of developers level up their skills. 📚 Wherever there was a stage, a classroom, or a hackathon floor, we showed up to help make Web3 safer and more accessible. To all the people and communities we met along the way: thank you. Let’s do it all again in 2025. 🌟

🎆 Goodbye 2024, hello 2025! This past year, we’ve seen incredible strides in #ZeroKnowledge and blockchain security. But there’s still work to do. Our 2025 motto is: Zero Knowledge, Infinite Trust This year, we’re doubling down on: 🔒 Auditing the next wave of ZK projects 🤝 Collaborating to build trust in #Web3 🚀 Supporting innovation in a safer ecosystem Let’s make 2025 the year we secure the future of blockchain—together. Happy New Year! 🥂 #ZeroKnowledgeinfinitetrust

ZK systems are incredible but complex. Auditing them isn’t just about catching bugs, it’s about ensuring the math, cryptography, and integrations hold up under pressure. It’s what we love working on at @Extropy. Get in touch: security.extropy.io
