Why this stack

HyperEVM gives programmable custody. A contract can own a HyperCore account, so every vault is its own account owned by its trader.
HyperCore gives the markets. One engine for perps, equities, commodities and outcome markets.
Plain Node services. Node 22 runs the TypeScript directly, with no build step to drift from what runs in production.
