Rate transparency is actually the most underrated capability in on-chain perpetuals.

The biggest issue with most products is not the technology, but the uncertainty of fees: funding fees can fluctuate several times within a few hours, depth is thin, and the cost of holding positions directly outweighs market fluctuations. Long-term strategies can hardly run stably in such an environment.

Ostium anchors the fee rates to real financing costs, and the rolling range is visible and can be estimated in advance. At the moment you open a position, you can roughly know the future holding costs, which transforms the strategy from "betting on risk" to "calculating costs."

For professional traders, this level of certainty is infrastructure-level. If you really want to do on-chain perpetuals, this step will have to be made up sooner or later.

What is rare about Ostium is that it does not treat this as a selling point, but rather directly incorporates it into the product. This makes me feel that it is worth long-term observation.
