Smart contracts are programs on a blockchain that execute agreements automatically when specific conditions are met, eliminating the need for human middlemen. They function like digital vending machines, relying on code to handle assets, transactions, and complex financial operations. While they offer transparency and 24/7 availability, they are limited by their code's security and their inability to independently verify external data, which is why oracles are essential. Today, they underpin massive sectors like DeFi, stablecoins, and tokenized real-world assets.

If you've ever held a stable coin, swapped one token for another, bought an NFT, or touched a DeFi app, you've almost certainly interacted with one. Stable coins alone are a $300 billion sector and the biggest of them rely on smart contracts to function. Yet most people using them every day couldn't tell you what a smart contract is actually doing behind the scenes. So how did a few lines of code become responsible for moving and managing hundreds of billions of dollars? And why can they do things that once required banks, lawyers, and other middlemen? Well, that's exactly what we're going to be breaking down f…
