DeFi relies on trustless systems—but what happens when trust is misplaced?
The Alpaca Finance incident shows how critical oracles are for protocol safety and how cutting corners can lead to millions in losses. Let’s break down @RektHQ article:👇👇

Alpaca Finance used a manual price feed system: updating CoinGecko prices every 30 minutes by hand.😳

In a fast-moving market, this was a disaster waiting to happen—and it came crashing down 📉during Thena’s Binance listing, where prices jumped from $0.26 to $4 in minutes.

❓The result?❓

Under-collateralized trades: Users exploited the lagging price feed to withdraw tokens worth far more than they deposited.

Alpaca’s losses? Disputed, but reports suggest damages over $2.8M.
The protocol paused trading—but by then, it was too late.

How did Alpaca respond?

Critics raising concerns were banned from Discord.

A compensation fund of just $50k—scraps compared to user losses.💔

Defenses like “No oracle could have captured this price surge”—ignoring better solutions like TWAPs or Chainlink.

The irony? Alpaca’s docs promised a “sophisticated oracle system” with Chainlink integration. Yet they gambled user funds on a system that boiled down to a browser refresh.

This wasn’t just negligence—it was a breakdown in infrastructure and accountability.

This is a wake-up call for DeFi: ⏰

If your system can’t handle volatile markets, maybe it’s not ready for user funds.

Oracles are critical infrastructure, not an afterthought. Build them like lives (and funds) depend on it—because they do.

At Extropy, we believe security isn’t optional. From oracles to contract design, every component matters.

Incidents like Alpaca remind us why robust systems—and audits—are vital. Let’s raise the bar for DeFi together.⛰

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:
https://t.co/pWDAAFXHKW

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. 🌟
