Detailed Description

Invariant: Validates counts of NFTokens after all transaction types.

The following checks are made:

• The number of minted or burned NFTokens can only be changed by NFTokenMint or NFTokenBurn transactions.
• A successful NFTokenMint must increase the number of NFTokens.
• A failed NFTokenMint must not change the number of minted NFTokens.
• An NFTokenMint transaction cannot change the number of burned NFTokens.
• A successful NFTokenBurn must increase the number of burned NFTokens.
• A failed NFTokenBurn must not change the number of burned NFTokens.
• An NFTokenBurn transaction cannot change the number of minted NFTokens.
