Introduction

The SSOL staking contract is a Solana program that enables users to stake SSOL tokens and earn rewards. It was developed as a conversion from the original SSOL token program, with a focus on security, efficiency, and user experience.

Key Components

1. State Management

   • StakeAccount: Stores user staking information
   • StakePool: Manages global staking pool state
   • StakeConfig: Contains staking parameters

2. Instructions

   • Initialize: Sets up the staking program
   • Stake: Allows users to stake tokens
   • Unstake: Enables users to withdraw staked tokens
   • ClaimRewards: Distributes staking rewards
   • UpdateConfig: Modifies staking parameters

Features

1. Staking

• Users can stake SSOL tokens
• Minimum stake amount: 1 SSOL
• Staking period: 7 days minimum
• Rewards accrue daily

2. Rewards

• Daily reward rate: 0.1% (configurable)
• Rewards are distributed proportionally
• Automatic reward calculation
• Claimable at any time

3. Unstaking

• 7-day cooldown period
• Partial unstaking supported
• Automatic reward distribution on unstake

4. Administration

• Configurable parameters
• Emergency pause functionality
• Reward rate adjustments
• Pool size management

Implementation Details

State Management

pub struct StakeAccount {
    pub owner: Pubkey,
    pub amount: u64,
    pub start_time: i64,
    pub last_claim_time: i64,
    pub rewards_claimed: u64,
}

pub struct StakePool {
    pub total_staked: u64,
    pub total_rewards: u64,
    pub reward_rate: u64,
    pub last_update_time: i64,
    pub is_paused: bool,
}

Key Functions

1. Staking

   • Validates stake amount
   • Creates stake account
   • Transfers tokens
   • Updates pool state

2. Reward Calculation

   • Time-based accrual
   • Proportional distribution
   • Automatic updates

3. Unstaking

   • Cooldown validation
   • Partial withdrawal support
   • Reward distribution

Optimizations
