Documented, with gaps
GMX scores 8.2 out of 10 and ranks #7 of 8 in the best defi protocols table, strongest on security record (8.4) and weakest on real usage (8.0).
Pioneered pooled-liquidity perpetuals and still runs one of the most understandable risk models in DeFi, with fees genuinely distributed to liquidity providers. Its market share has fallen sharply to newer order-book venues.
4 axes, weighted as published in the table’s methodology. Each score below is read from the fact printed under it.
8.4/ 35% of the score
In production since 2021; the record includes a 2022 price-manipulation episode on a thin market and a July 2025 re-entrancy in the v1 GLP accounting path that took roughly $40m, returned in full by the attacker for a $5m bounty.
8.0/ 25% of the score
Trading and borrow fees are paid by users and distributed on-chain to liquidity providers, with emissions a smaller component.
8.2/ 20% of the score
Governance operates through token votes with a timelock, while oracle configuration is controlled by the team.
8.2/ 20% of the score
Fee income has persisted since 2021 but has fallen with market share.
GMX distributes trading and borrow fees on-chain to the liquidity providers who take the other side of trader profit and loss. Not emissions, not a governance promise: real income from users, paid to the capital at risk. In a sector where most yields are dilution wearing a percentage sign, that mechanism is worth understanding.
The counterparty is a pool whose composition is public, priced by an oracle rather than a book. Anyone can see what backs their position, which is more than most venues in any market can offer.
A 2022 price-manipulation episode on a thin market, and a July 2025 re-entrancy in the v1 GLP accounting path that took roughly $40m — returned in full by the attacker for a $5m bounty, after which v1 was wound down. Oracle-priced execution removes slippage and concentrates risk in the feed.
Order-book venues have taken most of the flow. Fee income has persisted since 2021 but declined with volume, and governance operates through timelocked token votes while oracle configuration stays with the team.
Liquidity providers who want fee income from a pool whose composition they can read, and traders who prefer a counterparty they can inspect over a tighter spread they cannot explain.
Traders pay open, close and borrow fees, which are distributed on-chain to liquidity providers who also take the other side of trader profit and loss.
Twice in effect: a 2022 price-manipulation episode on a thin market, and a July 2025 re-entrancy in the v1 GLP accounting path worth roughly $40m, which the attacker returned for a $5m bounty.
Its fee distribution and transparent counterparty model remain distinctive, but order-book perpetual venues have taken most of the trading volume it once had.
