DeFi applications are built on open-source protocols, allowing anyone to inspect the code, contribute to its development, or even fork the codebase to create new applications.

This transparency fosters innovation, encourages collaboration, and builds trust within the community.

Smart Contracts

Smart contracts are self-executing contracts with the terms of the agreement directly written into code.

In DeFi, smart contracts govern various financial operations, such as lending, borrowing, trading, and asset management.

These smart contracts automatically execute transactions when predefined conditions are met, without the need for intermediaries.

DeFi applications represent a transformative force in the financial industry, offering greater accessibility, transparency, and efficiency compared to traditional financial systems.

However, they also present unique challenges, such as security vulnerabilities, regulatory uncertainty, and scalability limitations, which require ongoing innovation and collaboration within the DeFi community to address.

Oracle Services: An Overview
