# Mint and Redeem USP at the Contract Level

The Funding Manager is the core smart contract responsible for managing USP minting and redemption flows. It enables direct interaction with the protocol at the contract level, primarily intended for larger or institutional-sized operations. 

The Funding Manager handles token minting and redemption based on oracle price feeds. While minting is processed instantly, redemption requests are queued for delayed execution to ensure orderly liquidation of underlying strategy assets.
