so my question here is, does every meta data load resolve into a metadata_onchain type message? Wondering if there is a different struct for off-chain metadata?

In case of offchain metadata:

  • extension is empty onchain Metadata (with None values for each prop like image and attributes)
  • token_uri is used for offchain data, e.g. refers to an IPFS link with offchain metadata. Here JSON file on IPFS is exactly the same type for Metadata (as defined by ERC721).

So SG NFT mint is done by this:

        let msg = cw721_metadata_onchain::msg::ExecuteMsg::Mint {
            token_id,
            token_uri, // holds off-chain metadata
            owner,
            extension, // holds on-chain metadata
        };

Just wondering here, if off chain metadata is minted in this way, shouldn't we not use an execute message from cw721_onchain such as to not confuse the developer? I think the data is fine just coming from the cw721_metadata_onchain directory might be a bit misleading.

Oh my bad (wrong example given above). This is an sg-implementation, proper code is using this:

        let msg = sg721_metadata_onchain::ExecuteMsg::Mint {
            token_id,
            token_uri, // holds off-chain metadata
            owner,
            extension, // holds on-chain metadata
        };
        to_json_binary(&msg)

Please note that mint_msg() returns StdResult<Binary> for ics721 and sg-ics721.

Resolved in discord, name is coming from external repo

token_id,
token_uri, // holds off-chain metadata
owner,
extension, // holds on-chain metadata
};
to_json_binary(&msg)
}
}
