Every decentralised perpetual exchange to date sells the same product: delta. You are long the price or short it, and the venue is the counterparty to whichever side is crowded. In a trend, that is 90% of open interest pointing the same way and an LP vault carrying the whole opposite book.
That structure has one predictable failure mode. The crowded side is right until it is violently wrong, and the vault that was quietly collecting fees discovers it is the last bid in a cascade. No amount of insurance fund sizing changes the shape of the problem, because the imbalance is a property of what is being sold.
Selling a different risk
PrismPerp lists two instruments whose natural order flow is two-sided. Implied volatility has structural buyers (anyone hedging a catalyst) and structural sellers (anyone farming premium) at all times. Funding basis has structural payers and structural receivers by construction — it is a spread, and spreads have two ends.
- $C-VIX 30D — continuous 30-day implied volatility across the BTC and ETH surface.
- $FR-BASIS — the funding spread between Robinhood Chain and the mean of Binance and Hyperliquid.
