Searching for Sustainable Tokenomics in DeFi

It feels like every new protocol promises revolutionary tokenomics, but after a few months, the emission schedule kicks in and the price tanks. I’m genuinely curious are there any projects out there that have built a model you’d consider truly sustainable? I spend a lot of time in the yield farming trenches, and it’s getting harder to tell what’s a solid economic design versus just clever marketing for a token that’s destined to bleed out. What mechanisms have you seen that actually create real, lasting demand for a token, beyond just farming rewards? I’d love to hear which protocols you think are getting it right, or if the whole space is still figuring this out.
