Decentralized Finance (DeFi) has emerged as a transformative force in a sector that had been playing by the same rules for decades. Challenging traditional banking and financial services, DeFi offers a more open, accessible, and efficient way of doing things through blockchain technology. At the heart of it lie smart contracts – self-executing programs that automate and enforce the terms of an agreement under certain conditions defined in their code, ensuring transparency and trust without the need for intermediaries.

Smart contracts have evolved from simple scripts to sophisticated programs that facilitate complex transactions within the DeFi ecosystem. The introduction of Ethereum smart contracts marked a significant milestone, opening up the creation of decentralized applications (dApps) that, while imitating all manner of services, can run faster, offer reduced costs and give more control to the user compared to their traditional counterparts.

However, the limitations of first-generation smart contracts soon became apparent, giving rise to Smart Contracts 2.0. These address previous shortcomings by incorporating advanced technologies like oracles, IoT, and AI. The Hedera Hashgraph platform has been at the forefront of implementation, aiming to scale the Ethereum Virtual Machine (EVM) to improve transaction volume management and speed. In turn, AI's role in Smart Contracts 2.0 enables the analysis of vast amounts of data to predict market trends, enhance fraud detection, automate intricate transactions, and provide customized services.

Companies leverage smart contracts to upgrade their operations, including asset management, decentralized exchanges (DEXs), lending and borrowing, stablecoins, and decentralized banking. For example, protocols like Compound use smart contracts to automate the matching of borrowers and lenders, calculating interest rates based on supply and demand. This system can provide instant loans without traditional paperwork, which contrasts sharply with the lengthy processes and fees in conventional banking​.

Being the backbone of cheaper, faster and more transparent alternatives, smart contracts also make financial systems more inclusive, especially for underserved communities. Although most governments lag behind in addressing the necessary legal and regulatory issues that prevent a greater integration of decentralized digital solutions, blockchain-based financial tools are increasingly becoming part of everyday life.
