DefiLlama daily open interest. Missing days are left as gaps. The scale starts at zero.
Open interest and fees: DefiLlama, captured 08 Oct 2026 · 14:43 UTC. 24h volume: CoinGecko derivatives exchange data (rolling 24 hours, converted from BTC), captured 08 Oct 2026 · 14:43 UTC. Token prices and 30-day price change: CoinGecko, at the time shown on each venue page; a parent-project or chain token is labelled and is not evidence of a claim on exchange revenue. Changes compare the last 30 days with the previous 30 days (OI as a daily average, fees as a total) and need at least 95% daily coverage. A trend label needs the 30-day move to pass a threshold (OI ±25%, fees ±30%) on a minimum base (OI ≥ $5M, fees ≥ $100K per 30 days); with 90 days of history both horizons must agree. Venue-reported volume is not audited; ⚑ marks volume above 25× open interest. “—” means unavailable, never zero. Full method ↗
