Shareclass

The x/shareclass module enables users to delegate their RISE tokens without voting rights and earn staking rewards. This allows participation in staking using RISE tokens even without holding vRISE (non-transferable staking tokens).

Key Features

1. Non-Voting Delegation with RISE:
   • Users can delegate their RISE tokens to validators.
   • Delegation does not grant voting rights, separating staking rewards from governance participation.
2. Earning Staking Rewards:
   • Delegators earn staking rewards based on their delegated RISE amount.
   • Provides an alternative way to earn rewards for RISE token holders.
3. Validator Creation:
   • Supports the creation of new validators within the network.

Core Concepts

Non-Voting Delegation

Users can delegate their RISE tokens to a chosen validator. The module handles the calculation of shares and rewards. This mechanism allows users to benefit from staking rewards without needing to manage vRISE tokens or participate in governance directly.

Reward Calculation

Staking rewards are calculated based on the amount of RISE delegated and the reward parameters of the module. Users can claim their accumulated rewards.

Workflow

1. Delegate RISE (Non-Voting)

• User sends a MsgNonVotingDelegate transaction, specifying the validator and the amount of RISE to delegate.
• The module records the delegation and calculates the corresponding shares.

2. Claim Rewards

• User sends a MsgClaimRewards transaction to claim their accumulated staking rewards for a specific validator.
• The module transfers the rewards to the user’s account.

3. Undelegate RISE (Non-Voting)

• User sends a MsgNonVotingUndelegate transaction to withdraw their delegated RISE.
• The module processes the undelegation request, and the tokens become available after an unbonding period.

4. Create Validator (Optional)

• A user can send a MsgCreateValidator transaction to register a new validator node on the network.
