Thanks for your comment!
Yield from apxETH is purely from ETH staking. Boosted yield is offered via Dinero’s two token model, as some users will choose to hold pxETH. Therefore each apxETH benefits from staking rewards from more than one staked ETH, amplifying the yield for apxETH users.
Redacted is able to scale yield by providing incentives in the form of it’s native token $BTRFLY and utilising large treasury of DeFi bluechips.
It’s difficult to know how long the rates will be multiples higher than market average as it depends on TVL and the ratio of pxETH to apxETH. I expect the yield to come down over the coming year as TVL grows but it should always be above average Ethereum LST market rate given the two-token model.
