fToken Functions

Mint: Equivalent amount of fTokens are issued directly to your wallets when your funds are successfully supplied to Wing lending pools. You can view fToken balance on OKT Explorer by looking up your OKT addresses.

Redeem: You are able to redeem all or partial of their fTokens at any time by withdrawing funds you supplied to Flash Pool (OKC).

Transfer: Similar to the process of transfering other OKC based assets, you can transfer fTokens using a crypto wallet supporting OKC, for example Onto wallet. Transferring fTokens equals to changing the ownership of the underlying asset.

Earn interest: Assets supplied to Wing lending pools generate interest based on an Annual Percentage Rate (APR). The interest is reflected on fTokens exchange rate. I.e., fTokes balance remains unchanged, but fTokens appreciate over time. The longer you hold fTokens, the higher amount of underlying assets you can redeem from fTokens.
