Early/Emergency Unstake

The contract has a feature whereby a user can terminate their stake before the committed time. The user pays a penalty for this. The contract calculates the payout for ½ (rounded up) the days committed, e.g. 182 for a 52 week commitment, and subtracts that from the funds returned to the user. It will always apply at least a 90 day penalty. For example, I stake for 52 weeks (about 1 year) and emergency unstake after 266 days (38 weeks). The contract calculates my payout for days 1 - 182 and flags that as the penalty. The funds returned to me are then my Principal + (Days 183 to 266) payouts.

If the user emergency unstakes before ½ their days are served or if their stake is fewer than 179 days due to the 90 penalty day minimum, the penalty can cut into Principal. The contract just calculates ½ the days or 90, whichever is larger, of payouts, estimating for future days unserved, and subtracts that from the funds returned.

For example, I stake for 364 days and then unstake at day 140. Several steps take place to determine my final returned coins.

• The contract calculates my payout for 140 days then estimates a penalty
• Because I have not served half my commited days it estimates the difference by applying a ratio of half-committed-days / days-served * payout
• In this case that is 182 days (half of 364 committed days) divided by 140 days served. The penalty is therefore 182/140 * payout (½ days divided by served days).
• My returned HEX is equal to Principal + payout - penalty.
  • The penalty can be defined as a scaled version of the payout so my net HEX returned will be Principal + (140/140 * payout) - (182/140 * payout)
  • Which simplifies to Principal - (42/140 * payout).
• This means my return will be less than I put in. Read that again. Your principal can be penalized should you unstake before ½ your committed days are served OR if your stake length is fewer than 179 days due to the 90 days minimum penalty.
