How does Klever work?

Excuse me, could you please elaborate on how Klever, the cryptocurrency platform, functions? I'm particularly interested in understanding its unique features and how they contribute to its functionality. How does Klever facilitate seamless transactions across multiple blockchains? Does it provide users with a user-friendly interface and advanced security measures? I'm also curious about its integration with wallets and exchanges, and how this benefits its users. I'd appreciate a detailed explanation of its inner workings.
