What is the total supply of XDB chain?

Excuse me, I was wondering if you could provide some clarification on a specific aspect of the XDB chain. Specifically, I'm interested in knowing what the total supply of XDB tokens is. Is there a fixed cap on the number of tokens that will ever be in circulation, or is the supply dynamic and subject to change over time? Understanding the total supply is crucial for evaluating the potential for growth and scarcity of the token, so I'd appreciate it if you could enlighten me on this matter. Thank you.
