An Initial DEX Offering (IDO) is a fundraising method used by cryptocurrency projects to launch their tokens directly on decentralized exchanges (DEXs). It allows projects to raise capital by offering their tokens to investors through decentralized platforms, bypassing traditional fundraising methods and intermediaries. IDOs typically involve the sale of tokens at predetermined prices, often accompanied by liquidity pools and yield farming incentives. While IDOs offer increased accessibility and decentralization compared to traditional initial coin offerings (ICOs) or initial exchange offerings (IEOs), they also come with risks such as volatility and potential for manipulation.
