Description

Parses NFToken and URIToken (referred as NFT) Transactions (NFTokenMint, URITokenMint, NFTokenBurn, URITokenBurn, NFTokenAcceptOffer, URITokenBuy, NFTokenCancelOffer, URITokenCancelSellOffer, NFTokenCreateOffer, URITokenCreateSellOffer, Remit) with account context and returns affected NFT, direction that NFT was transferred, minted or destroyed, and outputs roles referencing account has in specific transaction.

With this parser you can find out what has happened with referencing account after transaction was executed. For example when token is minted - parser will output token ID and direction IN, this means referenced account was minter and new token is added to reference account ownership.

Remit (XLS-55)
Remit Transaction Type can mint a single URIToken which is present in this transaction like any other NFT. Additionally Remit can transfer none, one or more existing URIToken-s from Account to Destination, those tokens are present in nfts and ref.nfts array key, sending Account has role 'SELLER' and receiver Destination has role 'OWNER'.

What is checked:

• Token id - affected token ID in question
• Token direction - minted - IN, burned, OUT, sold - OUT, bought - IN
• Roles - role of referencing account in this transaction, is it minter, burner, seller, buyer, broker, or issuer
• Remitted URITokens - list of tokens transferred in Remit transaction type

Note about NFToken (XLS-20) issuer:
Issuer can only happen in NFTokenAcceptOffer transaction type, it is extracted from modified AccountRoot node by checking if balance has been changed. If yes then this account gained percentage of sale, and it is issuer of NFToken.
