Decentralized exchanges (DEXs) are increasingly challenging the early-stage financing dominance of centralized exchanges (CEXs). DEXs, operating on blockchain with smart contracts, offer trustless, transparent trading, reducing reliance on intermediaries. This appeals to projects seeking fairer token launches via Initial DEX Offerings (IDOs), which provide instant liquidity and community-driven funding. Unlike CEXs, where listings often involve high fees and gatekeeping, DEXs enable startups to raise capital more accessibly. Data shows IDO fundraising surged in 2024, with platforms like Uniswap and PancakeSwap facilitating millions in token sales. However, CEXs still hold sway for larger projects due to their user base, regulatory compliance, and market depth. While DEXs are gaining ground, they face challenges like scalability and user experience. The shift is evident, but CEXs remain relevant for now.
