Major perpetual decentralized exchanges (DEXs) experienced weak trading volumes over the weekend, with none surpassing $4 billion in 24-hour volume as of December 22. Lighter led the pack with $3.84 billion, followed by Aster and EdgeX. Hyperliquid recorded $2.43 billion in volume, although it noted an increase in open interest due to a volume breakout strategy that favored leveraged positions. Data from DefiLlama confirmed the subdued trading activity across these platforms.
