Decentralized Ad Exchange in 2025: The Ultimate Guide for Crypto Startups
Introduction

The rise of decentralized ad exchange platforms is transforming the way crypto projects market themselves. Traditional ad networks like Google and Facebook have become less effective due to high costs, lack of transparency, and restrictive policies. In contrast, Web3 ad exchanges offer a trustless, transparent, and efficient way to reach targeted audiences.
