jiminy-staking

MasterChef-style staking math. Global reward-per-token accumulator, per-user pending rewards, reward debt snapshots, emission rates.

jiminy-staking = "0.12"

• update_reward_per_token - advance the global accumulator
• pending_rewards - unclaimed rewards for a user
• update_reward_debt - snapshot after claim or stake change
• emission_rate - per-second rate from total rewards and duration
• rewards_earned - total emitted over elapsed period

Precision: REWARD_PRECISION = 1_000_000_000_000 (10^12)

use jiminy_staking::*;

let new_rpt = update_reward_per_token(
    current_rpt, last_update, now, rate_per_second, total_staked,
)?;
let pending = pending_rewards(user_staked, new_rpt, user_reward_debt)?;
