# Account Layout

> ProtocolConfig, AssetConfig, Reserve, MarginAccount, Debt, Lite.

## ProtocolConfig `["protocol"]`

`admin`, `pending_admin`, `treasury`, `operating_mode`, `max_assets_per_margin`, `next_asset_index`.

Modes: `Normal = 0`, `BorrowPaused = 1`, `WithdrawOnly = 2`, `Halted = 3`.

## AssetConfig `["asset", mint]`

Mint, token program, reserve, Pyth feed id, `ltv_bps`, `liquidation_threshold_bps`, `liquidation_bonus_bps`, decimals, `max_confidence_bps`, `max_price_age_secs`, `collateral_enabled`, `borrow_enabled`, `max_collateral_per_margin`.

## Reserve `["reserve", mint]`

Accounted cash, borrow assets/shares, index, fees, kink coefficients, caps, status, last timestamp. Liquidity vault is an ATA owned by the reserve PDA. Share mint is `["share_mint", mint]` (classic SPL even when the underlying is Token-2022).

## MarginAccount `["margin", authority]`

Authority, status, counts, `collateral_asset_indexes[24]`, `debt_asset_indexes[24]`, event sequence, reserved Lite registry.

## DebtPosition `["debt", margin, reserve]`

`borrow_shares` only. Token debt is derived.

## LiteStrategyConfig `["lite_strategy", underlying_mint]`

Kamino program, market, authority, reserve, liquidity vault, collateral mint, token programs.

## LitePosition

Per-margin receipt + cost basis for one Lite asset index. Seeded under `lite_position` — see `lib/solana/lite-pdas.ts` for the exact client derivation used by the app.
