# Integrate Lending

> Supply and redeem from another client.

1. Derive `reserve`, `asset_config`, `share_mint`, user ATAs (underlying + shares).
2. Wrap SOL if the mint is WSOL.
3. Call `lender_supply` with `min_shares_out` from a quoted exchange rate minus slippage.
4. For redeem, pass shares and `min_assets_out`. Check `accounted_liquidity_assets` first.

Refresh the reserve if `last_update_timestamp` is old so the quote matches accrual.

vTokens are **not** accepted as margin collateral. Redeem first.
