Auto-Compounding Elemental Particles EP deposited in this vault is staked in the EP contract to generate rewards from new FBX emissions. The contract regularly claims FBX rewards, burn them for new EP and reinvests in the vault, compounding the interests.
The contract takes a 3.0% fee on FBX rewards to mint and permanently lock new fireEP, thus reducing FBX's maximum supply over time. Depositors receive fireEP tokens representing the value of the deposit. They are required to withdraw and can be used in other DeFi protocols.
