# Core Concepts

> Lending, cross-margin accounts, vTokens, health, oracles, and Kamino on Solana.

Vanna on Solana is one Anchor program (`vanna_lending`) plus a Next.js app. Lenders supply reserves. Traders borrow from those reserves through a per-wallet margin PDA and deploy into Jupiter and Kamino.
