### xKAYEN Redeems

During <mark style="color:yellow;">**xKAYEN**</mark> -> <mark style="color:red;">**KAYEN**</mark> redemptions, if the vesting duration isn't the maximum, the <mark style="color:yellow;">**xKAYEN**</mark>:<mark style="color:red;">**KAYEN**</mark> ratio <mark style="color:red;">will be lower than 1:1, down to a minimum of 1:0.5</mark>.

Example:&#x20;

*If Alex redeems 1000 <mark style="color:yellow;">**xKAYEN**</mark> with the minimal 15-day vesting period, he will obtain a 1:0.5 ratio, and receive 500 <mark style="color:red;">**KAYEN**</mark> in the end. A total of 1000 - 500 = 500 <mark style="color:red;">**KAYEN**</mark> are burned during the early redemption.*
