RewardPool

Introduction

The RewardPool contract encapsulates the emission logic for MOR tokens across multiple reward buckets. It defines how MOR tokens are distributed over time using emission curves, serving as a shared utility that ensures controlled and sustainable token issuance within the protocol.

The contract supports multiple independent reward pools, each corresponding to a specific bucket — a category of protocol participants eligible to earn MOR rewards. These buckets include Capital, Provider, Builder, Compute, Code, and Protection.

It implements a linear interval-based emission decay model using the LinearDistributionIntervalDecrease library. The contract allows the protocol owner to register reward pools with distinct configurations and provides utilities to query reward amounts over time. Each reward pool has its own emission curve, with customizable payout start time, emission amount, and decay interval.

By isolating emission logic from staking and distribution, RewardPool enables independent upgrades and adjustments to token economics without affecting user balances or yield sources. This modular design helps ensure scalability, transparency, and long-term reward sustainability across the ecosystem.

rewardPools

The MOR reward pools data, where the pool #0 is a capital reward. pool. rewardPools[<rewardPool>]

RewardPool[] public rewardPools;

struct RewardPool {
  uint128 payoutStart;

decreaseInterval	The interval in seconds between reward decreases.
initialReward	The initial MOR reward for the bucket. Wei.
rewardDecrease	The MOR reward decrease per decreaseInterval. Wei.
isPublic	true - for Capital bucket, false for others.
