The 4 vulnerabilities behind most DeFi hacks 👇 - Lack of input validation (≈32% of incidents, ~$1B lost) - Reentrancy (18% of hacks, still a classic) - Faulty proof verification in bridges (rare, but $912M lost) - Logic/math errors (costly in 2023: 62% of losses) Billions lost. Most preventable. That’s why I’m focused on smart contract security. Source: Halborn, Top 100 DeFi Hacks Report 2025

For paythos, I’ve been building a wallet setup that doesn't require users to download any app or hassle with getting into web3, by using passkeys. My goal is to make web3 as simple as possible while keeping the challenges in mind. I’ve looked into other projects and talked with others in the Algorand ecosystem. For mainstream adoption, it has to be as easy as using the application without blockchain. The benefits need to outweigh the drawbacks, and our solutions should address those drawbacks directly. I’ve started with something, and while it definitely needs more work and thought, every journey starts with a first step

Why smart contract security? In 2024 alone, billions were lost to preventable hacks. Most projects can’t afford a $20k+ audit, but can’t afford a hack either That’s the gap I’m working on closing Still early, still a blank canvas → if you’ve got an immediate pain, let’s talk
