How much does IDO cost?

Excuse me, could you please elaborate on the cost associated with an Initial Dex Offering, or IDO? I understand that it's a fundraising method specific to decentralized exchanges, but I'm curious about the financial aspects involved. Are there any standard fees or costs that participants or project owners typically have to bear? Additionally, are there any potential hidden costs or factors that could affect the overall expense of an IDO? It would be greatly appreciated if you could provide a comprehensive breakdown of the expenses associated with this process.
