# The Evolution of DeFi

Since the inception of Bitcoin in 2008, the world has witnessed the emergence of decentralized finance (DeFi) as a transformative force. While Bitcoin proved that a censorship-resistant and borderless financial system was possible, the DeFi movement has expanded that vision — enabling smart contracts, decentralized exchanges, and automated yield generation.

Yieltra enters this space not to reinvent DeFi, but to **refine it** — offering a system that is simple, sustainable, and truly automated.
