Which of the following items are included in a TA's transaction log?

• A. Issued Tokens
• B. Recovered or tokens that are turned in
• C. Lost Tokens
• D. All of the above

Answer: (D)

Complete visibility of token movements is what the TA transaction log aims to provide. A robust log should capture issued tokens to show what has entered circulation, recovered or tokens that are turned in to return tokens to the system or remove them from active use, and lost tokens to flag discrepancies and prevent fraud or double counting. Each of these events affects the overall token inventory and accountability in different ways, so including all of them gives the most accurate, auditable record. If any one category were omitted, gaps could emerge where issues, recoveries, or losses aren’t tracked, undermining reconciliation and security. Therefore, the most comprehensive choice is to include all of the above.
