How OBOL rates perpetual DEXs
A perpetuals venue is a risk engine first and an exchange second. When markets gap, what matters is whether the oracle keeps up, whether the insurance fund absorbs bad debt, and whether the protocol claws back from profitable traders when it does not. That is why the risk engine carries the most weight here.
Funding is scored as a cost, not a feature. A venue with cheap taker fees and structurally expensive funding is not cheap for anyone holding longer than a session, so we mark the all-in cost of a multi-day position alongside the headline rate.
Decentralisation claims get checked
Most perp DEXs run at least one centralised component: a sequencer, an off-chain order book, a permissioned oracle set, an upgrade multisig. We do not penalise that by itself — we penalise pretending otherwise. Venues that publish their trust assumptions plainly score higher than those that hide them behind the word trustless.
What we cannot see
Open interest and volume on a perp DEX can be inflated by wash trading and points farming, and incentive programmes distort both. Where a venue's activity is visibly incentive-driven, we discount it and say so in the review.
