All projects on Solana matching “mark”

When to use: you already have model inputs (S or forward mark, K, T, r, σ) and need fair value + hedge ratios — not market-premium IV. European BSM price + analytic Greeks (delta, gamma, vega, theta, rho). Works for equity spots and power/commodity forwards (use the maturity mark as spot). USDC exact on Solana/Base. Free fixed sample: GET /v1/demo/option-price.

Use this before you buy, swap, or recommend a Solana memecoin: trending tokens with a rug-check on each one. Every token gets a riskScore (0 to 100), a riskLevel, and a one-line verdict backed by top-10 holder share, mint and freeze authority, LP lock, and sniper or bundle share of early supply, plus liquidity, market cap, 5m/1h/24h price and volume, and pump.fun status. Unreadable checks are mark
