Treehouse community has introduced TIP 4, a proposal to allocate 50% of market efficiency yield (MEY) fees from tETH for open market buybacks of TREE tokens. The repurchased tokens will be stored in a DAO-managed address and may be used for ecosystem incentives or growth plans as per governance decisions. Buybacks will occur at least weekly. The proposal is currently under community discussion and will be put to a Snapshot vote soon.
