Core Concepts

Vanna connects liquidity providers with margin accounts that can use borrowed funds in approved external protocols.

Margin Accounts: token custody and account-level debt.
Lending Pools and vTokens: supply, borrowing, and receipt value.
Health Factor and Liquidation: collateral valuation and debt resolution.
Interest Rate Model and Oracle System: rates and prices.
Registry: permitted assets, contracts, and controllers.
Composable Leverage: deploying borrowed capital into Blend and AMMs.

These pages describe the Stellar testnet code, with XLM and three distinct USDC test assets. They do not establish that configured contracts match the deployed WASM or that every external pool is available.
