# Managers ### Buy longZCB Managers can buy `longZCB` of an instrument if they are bullish on an instrument. They can simulate how much returns longZCB will generate, given how much the underlying instrument will generate. ### Redeem longZCB They can later redeem `longZCB`. For the creditline, they will redeem it at maturity. For the lending pool, they can redeem it whenever they want to realize profit or offload risk from the lending pool. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
