Updating metadata

The provider needs to know the collection metadata to be able to create the offers. This includes collecting all the traits, and which NFTs have which traits. To do so, we use the Alchemy API.

The example repository already contains a traitsList.json file containing the metadata of several collections. If you want to provide offers for these collections, you don't need to update this file.

If you want to provide offers for collections that are not in this list, you'll need to update the traitsList.json file. To do so, you'll need to:

1. add ALCHEMY_KEY to your .env file
2. edit src/populateTraitsList.json and replace the addresses in the array by the addresses of the collections you want to provide offers for (they must all be on the same network)
3. check that the correct network is selected right after the array of addresses
4. run yarn populateTraitsList to populate the traitsList.json file
