In Q3 2023 Friktion, then Solana's largest options vault protocol, wound down. Its Volts — weekly SOL calls, cash-secured puts, and delta-neutral basis — held over $60M in TVL at peak. The wind-down left a structural gap: Zeta Markets still runs the options venue, but the standard framework for automated theta harvesting on Solana disappeared.
STRYK is that framework. It rebuilds Ribbon Finance's Theta Vault pattern from first principles for Anchor and Pyth — deterministic pricing, deterministic settlement, and no floating-point on-chain.
Prior vaults settled with off-chain price snapshots. STRYK computes premium, delta, gamma, theta, vega, and rho directly on-chain using Q64.64 fixed-point arithmetic. Determinism is a settlement guarantee, not a hope.
Market makers used off-chain RFQs, which fragmented liquidity and hid clearing prices. STRYK ships a Gnosis EasyAuction-derived Dutch auction. Every clearing price is on-chain, every bidder is $STRYK-staked, every default is slashable.
Weekly rollover was manual on legacy vaults. STRYK vaults are triggered by Clockwork threads. When expiry hits, the settlement, next-strike selection, auction start, and premium distribution all execute in a single tick.
STRYK ships five reference reservoirs — covered call, cash-secured put, and a delta-neutral perpetual-hedged pool — plus an SDK for teams to publish their own vault templates against the same executor.
