Excuse me, could you please elaborate on how exactly one goes about using Ston Fi? I'm somewhat familiar with cryptocurrencies and DeFi protocols, but Ston Fi seems to be a unique platform or service. Are there any specific steps or prerequisites that need to be met before starting to utilize Ston Fi? Perhaps you could provide a brief overview of the user experience, from setting up an account to actually engaging with the platform's offerings. Thank you in advance for your clarification.
