📈Staking PassKashToken (PKT)

The PassKashStaking contract allows PKT holders to stake tokens and earn rewards based on predefined staking plans. Staking helps secure the PassCash ecosystem, incentivizes long-term holding, and rewards users proportional to their stake and chosen plan duration.

Staking Plans

Users can choose from three distinct staking plans, each offering different reward rates and lock-up periods:

Plan ID	Duration	Daily Reward Rate	Locked?	Description
1	30 days	5% (500 bps)	No	Flexible plan, withdraw anytime after 30 days without penalty
2	180 days	15% (1500 bps)	Yes	Locked plan with higher rewards
3	365 days	30% (3000 bps)	Yes	Long-term locked plan with highest rewards

Note: Reward rates are expressed in basis points (bps), where 100 bps = 1%.

Staking Requirements

• Minimum stake amount: 1,000 PKT

• Maximum stake amount: 500,000 PKT

• Token: PassKashToken (PKT) — ERC20 compliant

How Staking Works

1. Stake Tokens: Users deposit PKT tokens into the staking contract under their chosen plan. Tokens are transferred securely using OpenZeppelin’s SafeERC20 methods.

2. Lock-up Period:

   • Locked plans require tokens to remain staked for the full duration (180 or 365 days) before withdrawal.

   • The flexible plan allows withdrawal any time after 30 days.

3. Reward Calculation: Rewards accrue daily based on the staked amount and plan’s daily reward rate:

   Reward=Amount×RewardRate (bps)×Days Staked10,000\text{Reward} = \frac{\text{Amount} \times \text{RewardRate (bps)} \times \text{Days Staked}}{10,000}Reward=10,000Amount×RewardRate (bps)×Days Staked​

4. Withdrawal: After the minimum duration (and lock-up for locked plans), users can withdraw their initial stake plus rewards. Early withdrawal is restricted on locked plans.
