I got tired of smart contract errors talking to me like I’m a computer. So I Built Unscrambled. Spoiler: I am not a computer. So why and how made this app. So it can be accessible to every developer on the planet. So first things first, what is a smart contract? A smart contract is a program stored and executed on a blockchain that automatically enforces rules and agreements between parties without needing a central authority. Every Solidity developer has a moment. A humbling, chair-spinning, why did I c...

Create a transparent, tamper-proof voting smart contract — perfect for polls, DAOs, and community decisions. Ever wondered how to build a voting system where results can’t be manipulated? Where every vote is transparent and verifiable? That’s exactly what we’re building today using blockchain technology. In this tutorial, you’ll create and deploy a decentralized voting smart contract on BNB Chain testnet. By the end, you’ll have a working voting system that anyone can use and verify. What you’ll learn: ...

Introduction Managing shared expenses with roommates or groups can get messy. To solve this, I built Roomiesplit, a decentralized expense-splitting app on Solana. With Roomiesplit, users can record shared costs, track balances, and settle up transparently — all on-chain. In this blog, I’ll share not just the app, but also my experience developing on Solana using Anchor and Rust, and how it compares to building on Ethereum’s EVM. Why Solana? Ethereum and its EVM ecosystem are the most familiar starting po...
