No events are recorded on Token page

Question

I created a token on polygon and transferred it several times, but these events don't appear on token page, while they appear on Contract page.

• https://polygonscan.com/token/0x18592e4271F3145453A2aaC7E1E139EB1A75a293

Why no events are recorded on Token page?

Answer 1

Notn100% sure but it might be related to your event definition.

In your Transfer event you are not marking the address fields as indexed.

According to the ERC-20 standard this is required. See:
