fUSDC is an Ethereum based token that can be minted when users deposit USDC on Flux Finance. Each asset supported by the Flux Finance Protocol is integrated through a fToken contract, which is a representation of balances supplied to the protocol. fTokens, such as fUSDC, are a fork of Compound V2's cTokens, with additional functionality to support permissioned assets.
By depositing USDC on Flux Finance, the user's USDC will become available to borrowers, and the user will earn the USDC supply rate. fUSDC increases in value relative to the underlying USDC, meaning users can redeem more assets over time as interest is earned. The interest rate earned by lenders fluctuates and depends on the market's utilization (i.e. the percentage of deposited assets that have been borrowed).
By minting fUSDC, users earn interest and gain the ability to use fUSDC as collateral. fUSDC can be transferred to effect change in ownership. Transferring fUSDC means transferring your balance of the underlying USDC inside the Flux Finance protocol. Transfers that would result in negative account liquidity for borrowers on Flux Finance will fail.
