Perpetual Protocol pioneered the Uniswap-V3-liquidity perp model on Optimism. Cross-margin trading, long operating record since 2020. Volume trailed newer competitors; still functional with development pace slowed.
What Perpetual Protocol is
Perpetual Protocol was one of the first on-chain perp DEXs with a novel design using Uniswap V3 concentrated liquidity as the underlying market maker. Deployed on Optimism.
Current positioning
Perp Protocol remains functional but has largely lost ground to Hyperliquid, dYdX, and Vertex on volume. Development pace slowed.
Verdict
Perpetual Protocol pioneered the concentrated-liquidity perp model. Still functional but momentum has shifted to newer venues.
