Rush Earn

The Rush Games Vault is a staking mechanism that allows users to earn rewards by staking their RUSH tokens. This section explains how the Vault works and how you can participate to earn passive income.

Overview

The Vault contract enables users to:

• Stake RUSH tokens and receive xRUSH tokens in return

• Earn rewards based on tiered APY rates

• Claim rewards at any time

• Withdraw staked tokens (after meeting the minimum staking period)

Key Features

Tiered Rewards System

The Vault implements a three-tier reward structure based on the amount of RUSH tokens staked:

• Tier 1: For balances below the tier 1 threshold

  • Current APY: ${tier1_APY/100}%

• Tier 2: For balances between tier 1 and tier 2 thresholds

  • Current APY: ${tier2_APY/100}%

• Tier 3: For balances above the tier 2 threshold

  • Current APY: ${tier3_APY/100}%

xRUSH Tokens

When you stake RUSH tokens, you receive an equivalent amount of xRUSH tokens (minus the deposit fee). These tokens represent your stake in the Vault and can be used in other parts of the Rush Games ecosystem.

Reward Calculation

Rewards are calculated hourly based on:

• Your staked balance

• Your applicable APY tier

• The duration since your last claim or deposit

The formula used is:

Annual Reward = (Staked Balance * APY Rate) / 10000
Hourly Reward = Annual Reward / (52 weeks * 7 days * 24 hours)
Total Reward = Hours Staked * Hourly Reward
