tier_rewards module

Introduction

Manages tiered staking positions with bonus APY on top of base staking rewards. Introduced in v7.0.0, CRO holders can lock their stake for a defined exit commitment period (1/2/4 years) in exchange for bonus APY (up to +7%).

The module also maintains a base reward floor (~3% APY) by topping up shortfalls from the Tier Rewards Pool.
