Eth Pool

Simple contract to stake eth to a pool and get rewards for staking.

Assumptions

• Rewards are deposited only once per cycle.
• Users can't withdraw partial amount (this wasn't clear in the requirement either if they are allowed to withdraw partial)

Algorithm

• Users are allocated an accounting token when they stake eth.
• The accounting token is ERC20Snapshot
• At every deposit of rewards, the snapshot is recorded.
• This snapshot record is then used to calculate the rewards of the user once the user withdraws
