Additional feature request

[Yvesil]

Thank you for the great work! Would it be possible to collaborate with you to add some extra features? I was thinking of:

1. Making the staking contract token emission have an exponential function
2. Making it so that both tokens have restricted transferability
   • where the ETB token can only be staked in the contract and swapped in a single specific swap contract
     ++ where the CakeLP token can only be swapped in a single specified swap contract

Hope we can get in touch!
