How do I know if I have ERC-20 tokens?
Excuse me, I'm trying to figure out if I have any ERC-20 tokens. Could you please tell me how I can check? I've heard about these tokens but I'm not quite sure how to verify if I have any in my possession. Is there a specific platform or tool that I can use to view my ERC-20 holdings? Also, could you explain what ERC-20 tokens are, just in case I'm not fully informed? I'd really appreciate your help in clarifying this matter.
