Welcome back to the #PolygonDeFiEducation series.

Today, we're taking a closer look at the engine powering Decentralized Finance - Smart Contracts.

Let's dive in 💦 From facilitating token trades in a decentralized exchange, lending & borrowing, minting NFTs, to governing a DAO, SCs enable many of the innovative features we see in the #DeFi landscape. SCs can interact with each other, forming building blocks for complex decentralized applications (dApps).

That’s called composability.

This is how most #DeFi applications are built. SCs run on the blockchain, meaning they're decentralized and immutable - once deployed, they can't be modified.

However, some can be modified by a governance vote or admin key.

This helps ensure trust and transparency as no party can alter the terms after deployment. A smart contract (SC) is a self-executing contract with the terms of the agreement directly written into lines of code.

It's "smart" because it executes or controls the agreement automatically. This highlights the importance of rigorous contract testing, auditing, and formal verification.

In the blockchain world, code is law, and flawed code can have significant consequences. However, SCs carry their share of risks.

If a contract has a bug or vulnerability, it can lead to loss of funds or other undesirable outcomes.

Notable examples include the DAO hack in 2016 and the Parity wallet issues. Ethereum has played a crucial role in popularizing smart contracts, with its Turing-complete programming language, Solidity, allowing developers to create complex contracts.

But SCs can exist on other blockchains too, like Polygon, Cosmos, and more. For example, a SC might release funds to a party upon a certain condition, like a specific date or the fulfillment of a certain task.

This is done without needing a middleman or a trusted third party.

SCs are a game-changing technology and the backbone of #DeFi.

They bring unprecedented transparency, efficiency, and automation to financial transactions.

Thanks for joining our #DeFiEducation series, stay tuned for more 🌐
