5. Reward System

Base Rewards

Source: 0.1% of all trading volume

Distribution: Proportional to stake amount

Formula:

User Reward = (User Stake / Total Stake) × Unclaimed Fees

Lock-Based Multipliers

Lock multipliers are applied to base rewards:

Lock Type	Multiplier	Total Commitment
Flexible	1.0x	0 days
ShortFixed	1.15x	30 days
ShortLinear	1.1x	30 days
MediumFixed	1.3x	90 days
MediumLinear	1.25x	90 days
LongFixed	1.6x	180 days
LongLinear	1.5x	180 days
VeryLongFixed	2.2x	365 days
VeryLongLinear	2.0x	365 days
TwoYearFixed	2.5x	730 days
TwoYearLinear	2.3x	730 days
ThreeYearFixed	2.8x	1,095 days
ThreeYearLinear	2.6x	1,095 days
Platform	1.0x	1,825 days (5 years)

Reward Calculation

// Calculate total reward multiplier
fn calculate_total_reward_multiplier(
    lock_multiplier_bps: u16,
    voter_bonus_bps: u16,
) -> u16 {
    // Additive: base multiplier + voter bonus
    lock_multiplier_bps + voter_bonus_bps
}

// Apply multipliers to rewards
fn accrue_rewards(
    staking_pool: &StakingPool,
    staker_account: &mut StakerAccount,
) -> Result<()> {
    let base_rewards = calculate_base_rewards(staking_pool, staker_account)?;
    
    let total_multiplier = calculate_total_reward_multiplier(
        staker_account.reward_multiplier_bps,
        staker_account.voter_bonus_multiplier_bps,
    );
    
    let final_rewards = (base_rewards as u128 * total_multiplier as u128)
        .checked_div(10000u128)
        .ok_or(ErrorCode::MathOverflow)?;
    
    staker_account.unclaimed_rewards += final_rewards as u64;
    Ok(())
}
