Amidst the launch of the new XRPL-native NFT standard, The Sologenic Development Foundation has devised a tool to verify the authenticity of XLS-20 NFTs that have been upgraded from the previous standard. This tool aims to detect forged NFTs by validating the signed and encoded JSON Web Token (JWT) on each NFTokenMint transaction considering Sologenicâs Private key signature cannot be forged.
The user-end tool will be available on sologenic-migration verification as soon as the amendment goes live on the XRP Ledger; moreover, the following article will elaborate on how to verify such signature and NFT data manually.
In addition to this guide, the Sologenic team will be providing anso npm library to facilitate the manual verification process outlined in the following steps:
Installing path for the npb library: npm i nft-conversion-verifier
6. In the payload object, you will be able to find the âtoken_idâ property. This âtoken_idâ should be compared to the NFTokenID of the actual NFT on the ledger, and they should match. If they donât match, the NFT might be a forge. As well, you will be able to find the XLS14 data of the NFT; currency code as âinternal_token_idâ and issuer as âcollection_idâ
7. After verifying the data, head to the section below âVerify Signatureâ and paste the provided Sologenic Public Key.
8. Lastly, after completing the previous step successfully, you should see the âValid Signatureâ message on the bottom left of the screen. If the information displayed on this section is anything else other than this, the NFT is invalid and might be a forge or it wasnât migrated through Sologenic.
This verification path is forgery-proof, as even if the same MemoData is pasted in another NFTokenMint transaction, that MemoData contains the NFTokenID of the correct NFT and should always match. There is no possibility of forging the NFTokenID as it is encoded with a Transaction Initiator Address.
