lender_supply(assets, min_shares_out)
Accrue. Measure what actually arrived in the liquidity vault (Token-2022 fees included). Mint vTokens at the current rate, at least min_shares_out. Respects supply_cap, the operating mode and the reserve status. The first deposit locks MIN_INITIAL_SHARES that nobody can redeem.
lender_redeem(shares, min_assets_out)
Accrue. Burn vTokens. Pay out at most available_cash (cash minus protocol fees). Require assets ≥ min_assets_out. Allowed in every reserve status except Frozen.
public_refresh_reserve
Permissionless accrual. Anyone can update a pool so its index isn’t stale before a quote.
Notes
- SOL is wrapped by the client before supply. The program sees wSOL.
- Unsolicited transfers into the liquidity vault do not change
accounted_liquidity_assets, so they can’t inflate the vToken rate. - The reserve counts its own lender shares (
total_supply_shares). vTokens burned outside Vanna don’t change anyone else’s claim.
