# Lending Instructions

> lender_supply, lender_redeem, public_refresh_reserve.

## `lender_supply(assets, min_shares_out)`

Measure the transfer into the vault. Accrue. Mint shares ≥ `min_shares_out`. First deposit enforces `MIN_INITIAL_SHARES`.

## `lender_redeem(shares, min_assets_out)`

Accrue. Burn shares. Pay `available_cash`. Require assets ≥ `min_assets_out`.

## `public_refresh_reserve`

Permissionless accrual. Anyone can poke a pool so indexes are not hours stale before a borrow.

SOL is wrapped by the client before supply. The program sees WSOL.
