Wicket
Wicket gives you shares in exchange for DUSK. You can turn the shares back into DUSK, with a floor you set so you never get less than you expect.
Deposit
Deposit moves DUSK out of the vault and gives you shares. It waits first. If the price moves so that you would get fewer shares than your floor, the deposit is refused.
Redeem
Redeem turns shares back into DUSK. One redeem can be open at a time. If the price moves so that you would get less than your floor, the redeem is refused.
Claim
DUSK that reaches the vault without being tied to a row waits as a credit. You can claim it onto this row. Claiming waits.
