# NFIL tokenomics
**What is NFIL?**
* NFIL is a token on the HashKing platform. When users stake FIL on HashKing, HashKing mints an NFIL certificate at a 1:1 ratio to record the staked FIL and the earned interest.
* NFIL can be exchanged for FIL through the SWAP feature. When there is sufficient liquidity in the staking pool, users can easily swap NFIL for FIL at a 1:1 ratio.
* Staking NFIL in the Staking pool allows users to earn rewards.
* When users pair NFIL with FIL to form the liquidity token pair FIL-NFL and stake it in the Farm, they can also earn rewards.
