# System Components

* kUSD stable token — SPL on Solana; ERC‑4626 on EVM and BNB Chain.
* Controller Router — entry point that orchestrates mint, burn, lock, unlock, redeem, and Safety Buffer actions.
* Perp Yield Vault (Drift‑style Solana program) — manages strategy sleeves, positions, NAV, exchange rate, and cooldown queues.
* BEP/ERC‑4626 Vault (EVM contract) — deposit asset is kUSD with NAV per share driven by proof-of-reserve oracle marks.
* Oracle Layer — asset prices and NAV feeds with freshness and deviation controls. Powered by Pyth / Chainlink.
