"""
CONCEPT HODLJENNER.COM
A community-driven staking project for the Etherum token $JENNER designed to encourage and reward the community by
holding onto the token.
Dedicated $JENNER HODLERS (not holders) can stake some of their $JENNER to the pool. When doing so, 3% of the total
staked amount will be shared amongst the stakers already in the pool.
A staker can exit the pool at any time they wish. They will be given back their INITIAL STAKE (minus fees) plus
their share of the Fee rewards.
