- How can you understand that a Transfer event is an ERC721 transfer?Sasha Shpota– Sasha Shpota2022-02-09 18:40:43 +00:00Commented Feb 9, 2022 at 18:40
- @SashaShpota In order to decode the logs associated with a certain transaction, which will also include the emitted Transfer event, you will need to use an ABI. That ABI specifies the expected structure for the Transfer event you are looking for, which differs for ERC20, ERC1155, and ERC721 transfer events. What seems to work, if you are just looking for ERC721 transfer events, is to only provide your decoder with that ABI. As such, it won't be able to read the transfers for the other types of tokens, and you'll know they aren't ERC721. Hope that helps!Valentijn van den Hout– Valentijn van den Hout2022-02-14 07:21:39 +00:00Commented Feb 14, 2022 at 7:21
- But some NFT is missing when I use the API by moralis.io. I tried to sync the NFT contract for indexing, but sill several NFT are missing for some EOA. Very hard to figure out what is wrong with it. No support at all for free plan user.Kronos– Kronos2022-03-22 12:03:39 +00:00Commented Mar 22, 2022 at 12:03
- You can get help in the Moralis discord or forum. Usually when NFTs are missing it either doesn't adhere to any common ERC standard, or the metadata wasn't available to be fetched. But I'm sure the Moralis team can help you debug.Filip– Filip2022-03-23 13:04:15 +00:00Commented Mar 23, 2022 at 13:04

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. go-ethereum), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
