For the 1st mainnet version, Optimus will return reward token (BALN) directly to users' wallet. FIN token reward will be added for 2nd version release in tandem with OMM integration. Details of FIN reward calculation will be updated here soon.
Note: we believe BALN, OMM and FIN will grow in value together. Therefore, our strategies will not sell BALN / OMM into ICX for farming more; rather stake those tokens for a higher return.
