Unlike traditional products, Everlong does not rely on external capital to form liquidity. Instead, it creates the counter-asset internally, allowing users to remain fully long while earning yield. Everlong sits at the intersection of two structural problems in DeFi: * the lack of sustainable, asset-denominated yield for long holders * the expense of sourcing efficient stablecoin liquidity, which has historically capped CDP growth It solves both simultaneously by turning passive holdings into productive liquidity that scales with the position itself. ### **Why Everlong** Since 2021, liquidity-provisioning has stagnated because the yield has not out-performed holding the individual assets separately. LPs face both impermanent loss and losses versus re-balancing, making participation increasingly unattractive.

However, lending has continued to grow, demonstrating that there is demand for yield denominated in the deposit asset.

Everlong turns BTC into productive liquidity without sacrificing exposure to the underlying asset. It creates a new primitive for yield, offers composability for the depositor and productive liquidity wherever it is deployed.
