When a user opens a new stake, they choose an amount of SWAPP to stake, and a stake length in days. The minimum stake amount is 0.000000000001 SWAPP (1000000 TESLA). The minimum stake length is one day, and the maximum stake length is 15,330 days (just under 42 years).
Once a stake is opened, it is in “Pending” status. This means that the stake won’t technically begin until the following day. A user may close a stake in Pending status, receiving back the stake’s principal, without penalty or interest.
Pending stakes become “Active” status once the next day begins. At this point, closing the stake before it reaches “Mature” status will incur a penalty.
When a stake is opened, the SWAPP tokens staked are actually burned by the contract and converted into "INTR$T" These shares exist for the life of the stake. Once the stake is closed, the INTR$T is destroyed, and SWAPP is minted back to the user (along with any interest added and penalties deducted).
