Is SAND an ERC-20?

I'm quite curious about the nature of SAND tokens. Could you please clarify for me if SAND is indeed an ERC-20 token? I've heard a lot about ERC-20 tokens and their compatibility with the Ethereum blockchain, but I'm not entirely sure how to identify one. Would SAND's ERC-20 status mean it follows a standard set of rules and procedures, enabling seamless interoperability within the Ethereum ecosystem? Also, if SAND is ERC-20, does that mean it can be stored and managed on various wallets that support ERC-20 tokens? It would be helpful if you could break this down for me.
