Ok, so tried out @hylo_so today. It is a very interesting protocol and the @colosseum investment intrigued me (I am an LP in Colosseum fund). I am suuuuper wary of algo stables, even if overcollateralized, so approached this with caution. Mechanism is new and interesting with 2 token model - xSOL, a leveraged SOL and hyUSD, a pegged stable - backed by jitoSOL collateral. This is made FOR bull markets. My concerns here are 2 fold - cost and existential risk. 1. Cost - For anyone that use stables to generate yields, starting with USDC or other stables means you incur 0.1% fee + slippage to buy jitoSOL (that's the only collateral) in normal mode. Redemption costs 0.1% to redeem sHyUSD and 0.3% to redeem hySOL back to collateral. This is almost half a month of yield at current 16% top of the line yields on the stability pool. So know what you get into and be prepared. 2. Existential risks - a) SIMD228 or similar: sHyUSD basically generates its exorbitant yield using jitoSOL that is the underlying collateral. As staked SOL yields go down, this will struggle to provide market competing rates on top of the other risks it has. b) Prolonged bear: When SOL prices grind down for prolonged periods as they do in a bear, sHySOL keeps getting auto-converted to xSOL which is leveraged SOL. This is good for holders in bull markets as deep dips give you auto exposure to leveraged SOL for even better results. The result is the inverse in a bear. You will end up with nothing. c) Again, in a bear, as SOL prices grind down and collateral dips and sHyUSD keeps getting converted to xSOL which will be worthless, or users redeem to avoid this (redemption fee goes to 0.1% before it gets here) the entire pool keeps getting shrunk slowly, and the protocol shall enter cockroach mode. So, know what you are getting into before you do. The yields are great without need to loop or monitor leverage BUT the cost you incur needs at least a month to be in the pool to be on par with base yield. And if you are afraid of a looming bear, the risks amplify. One last thing is I wish the protocol chose INF instead of jitoSOL as collateral, for a plethora of reasons which I don't wish to get into here.
