The WISE contract allows users to stake their WISE, locking it up for a period of days, in order to earn interest. This is the primary function of the contract during the Circulation Epoch.
Users may open as many stakes as they like. After a stake reaches full maturity, the user may close it at any time to receive their full principal, plus interest, without penalty.
Unlike some other stakeable tokens, WISE never penalizes a mature stake, no matter how late it is eventually closed. This allows users much more flexibility, especially for taxable income purposes. Also, should a user pass away before being able to close their stakes in a timely fashion, the WISE contract thus remains in compliance with estate laws of various jurisdictions that make it illegal to penalize the assets of a deceased person.
