The yyAVAX liquid staking product hasn’t managed to find product market fit since its launch, and subsequently runs at a loss to the Treasury (liquidity incentives > revenue). The product also requires development resources to upkeep that could be better focused on Yield Yak's more successful products.
Additionally, from a competitive landscape POV, YAK tokenomics haven't proved to be well suited to fuel yyAVAX growth compared to competitors.
Sunsetting procedure: Users would be able to convert yyAVAX for AVAX at a fixed rate, once the AVAX staked on the P-Chain is unstaked and made available on the C-Chain.
Timeline: As this will require coordination across Eden (validators), Geode Finance (liquid staking infrastructure) and Yield Yak, timeline is TBD. Updates will be shared on relevant Discord and Telegram Announcement Channels.
