The IDO model stands out for its decentralization, liquidity, and transparency. Unlike ICOs that rely on centralized websites or IEOs that depend on exchange approval, IDOs operate on decentralized exchanges. Smart contracts handle token sales, ensuring instant delivery and liquidity pool creation. IDOs remove the dependency on centralized authorities, lowering launch costs and increasing accessibility. They also prevent manipulation since prices are determined by market dynamics through liquidity pools. Moreover, investors maintain full custody of funds via wallet connections, reducing risks of fund mismanagement. In essence, IDOs combine the benefits of automation, transparency, and instant market presence, making them the preferred model for Web3 projects.
