LineHub

LineHub is a one-stop DeFi venue on Linea that bundles spot swaps, perpetuals, V2 and V3 liquidity pools, automated liquidity management, bridging and an AI assistant into a single interface. Users trade across a dozen or so chains without switching networks.

Its core is a perpetual aggregator with chain abstraction: orders are split toward the deepest venue on each chain while settlement still occurs on the asset's native chain. Every chain and every collateral asset gets its own pool, an isolation design that limits contagion from one volatile asset. Pricing pulls from Pyth, Chainlink and API3 in parallel for cross-checking, and profit and loss is denominated in the collateral the trader picked. V3 pools include a single-sided entry tool to cut leftover tokens, leverage reaches 100x, and listed instruments span crypto, metals, FX and indices, with cross-chain state synced by a messaging middleware.
