Refresh and quote
Read the
Reserve. If last_update_timestamp is old, include public_refresh_reserve or project accrual off-chain so the quote matches.4
Supply
Call
lender_supply(assets, min_shares_out) with min_shares_out from the quoted rate minus slippage.5
Redeem
Call
lender_redeem(shares, min_assets_out). Payouts are limited to accounted_liquidity_assets − accrued_protocol_fees, so check available cash first.supply_cap, the operating mode, and the reserve status.
vTokens are not margin collateral. To use supplied funds as collateral, redeem first and deposit the underlying.
