Could you elaborate on the concept of Salesforce Apex Crypto? I'm particularly interested in understanding how it integrates
cryptocurrency capabilities into the Salesforce platform. Is it a new service offering, or does it involve the integration of existing crypto solutions? Additionally, what are some of the key features and benefits that Apex Crypto provides to Salesforce users? I'm also curious about the security measures Salesforce has implemented to ensure the safety of crypto transactions and data within its platform.
