Summary:
Kill emissions for Stax Frax/Temple xLP + LP pool by calling
set_killed().
Motivation:
On October 11, 2022, STAX Finance was hacked for $2.3m. The attacker managed to steal a total of 321,154 xLP. Following this, STAX removed access to its front end.
Looking into the Curve.fi xFraxTplLP-f Gauge Deposit contract reveals very few interactions with this gauge. Since the hack, there have been 1 deposit/withdraw, which looks to be yearn transferring to a new vault strategy. The gauge is supplied >99% by the TempleDAO farming wallet via Yearn vault strategy and <1% by a gnosis safe that appears to be connected with TempleDAO.
Since the exploit, the STAX Frax/ Temple LP has had basically no activity. This pool does not have any possibility to accept LPs, and has been used by TempleDAO to farm CRV behind a walled garden.
It has continued to bribe for CRV emission. In the latest Votium round, it bribed almost $100k, making this gauge inexplicably in the top 10 highest weighted gauge at 3.2%. Furthermore, Yearn has an agreement with TempleDAO to provide gauge weighting to the pool in exchange for a portion of CRV emissions earned by the pool, codified by this contract.
As one might expect, this pool creates negligible value for Curve, producing extremely low volume and fees.
This is the definition of a freeloader gauge, it has no business being incentivized by Curve.
