Infrastructure

The dam is engineered from ten primitives.

STRYK is a monorepo of nine on-chain and off-chain packages plus the web app you are reading. Each primitive is auditable in isolation; together they compose the reservoir.

pricingRust · Q64.64

Pricing engine

Black-Scholes-Merton call/put + full first-order Greeks. No floating-point on-chain. Range-reduced exp, Newton sqrt, and A&S 26.2.17 CDF are all deterministic.

· packages/pricing-engine
· IV surface with bilinear interpolation
· Verified with property tests

runtimeRust

Vault runtime

The scheduler that impounds deposits, opens auctions, records clearing prices, settles at expiry, and self-seals into the next week without operator intervention.

· packages/vault-runtime
· Clockwork thread hooks
· Deterministic Friday rollover

on-chainAnchor 0.31

Vault executor program

The Solana program that owns the vault PDA, holds LP shares as SPL tokens, and CPI-invokes Zeta / Drift adapters. IDL published on GitHub.

· packages/anchor-program
· PDA seeds: [vault, kind, epoch]
· Emergency pause + upgrade authority

auctionRust

Dutch auction layer

Gnosis EasyAuction pattern adapted for Solana. Prices decay linearly from 1.1x fair value to 0.9x over 15 minutes. Market maker whitelist gated by staked STRYK; default is slashable.

· packages/auction-layer
· On-chain clearing price
· Whitelist governance

adaptersRust + TS

Zeta + Drift adapters

CPI adapters into Zeta Markets for option minting and Drift Perpetual for delta-neutral hedging. Position sizing bounded to 0.98–1.02 delta band.

· packages/zeta-adapter
· packages/drift-adapter
· Bounded delta band

developerTypeScript

SDK + CLI + Mobile

One StrykClient shared across web, dashboard, mobile (React Native), and the `stryk` npm CLI. Read-only mode works without a wallet.

· packages/sdk-ts
· packages/cli — `npm i -g stryk-cli`
· packages/mobile-app

Reconstructed from Pyth SOL/USD hourly prices between 2026-05-30 and 2026-06-29. The vault ran a 15-delta OTM call each Friday against the deterministic pricing engine. Historic dataset served by /vaults/{pda}/backtest?days=30.
