TL:DR

The 1st batch of Kusama SALP corresponding vsBond is about to be expired, Bifrost had repurchased 75% unredeemed KSM to vsKSM, and trasnfered remaining 25% to Bifrost treasury. This proposal is aiming to burn those repurchased vsKSM.

(Learn about why expire time for vsBond) Bifrost uses unredeemed underlying KSM to repurchase vsKSM and burn, to maintain a long-term healthy price of vsKSM-KSM. The repurchasing and burning stracture as follow:

• Repurchase 75% unredeemed KSM to vsKSM;

• Remaining 25% KSM goes to Bifrost treasury;

For the first batch of unredeemed KSM, this proposal is to burn repurchased 755.55 vsKSM.
