# Staker

#### Introduction

The Staker receives protocol fees and rewards long-term $NEBY stakers. Stakers are rewarded based on their staking power, calculated as the amount of $NEBY staked multiplied by the stake duration.

Each staking position has an unlock time. Users may choose to receive rewards in $USDT or $wROSE, which applies to all their positions.

#### Roles

User:

* Stakers lock $NEBY for up to three years to receive staking power, determining their share of protocol fees.

Owner:

* Can set a StakerV2 contract for future upgrades, allowing users to migrate their positions.

#### Interactions

* Stakers can deposit yield without specific privileges for the ProtocolFeeManager.
