# State
|
|
|
|
## Parameters and Genesis State
|
|
|
|
`Parameters` define the types of incentives that are available and the rewards that are available for each incentive.
|
|
|
|
```go
|
|
// Params governance parameters for the incentive module
|
|
type Params struct {
|
|
USDXMintingRewardPeriods RewardPeriods `json:"usdx_minting_reward_periods" yaml:"usdx_minting_reward_periods"` // rewards for minting USDX
|
|
HardSupplyRewardPeriods MultiRewardPeriods `json:"hard_supply_reward_periods" yaml:"hard_supply_reward_periods"` // rewards for hard supply
|
|
HardBorrowRewardPeriods MultiRewardPeriods `json:"hard_borrow_reward_periods" yaml:"hard_borrow_reward_periods"` // rewards for hard borrow
|
|
HardDelegatorRewardPeriods RewardPeriods `json:"hard_delegator_reward_periods" yaml:"hard_delegator_reward_periods"` // rewards for kava delegators
|
|
ClaimMultipliers Multipliers `json:"claim_multipliers" yaml:"claim_multipliers"` // the available claim multipliers that determine who much rewards are paid out and how long rewards are locked for
|
|
ClaimEnd time.Time `json:"claim_end" yaml:"claim_end"` // the time at which claims expire
|
|
}
|
|
|
|
```
|
|
|
|
Each `RewardPeriod` defines a particular collateral for which rewards are eligible and the amount of rewards available.
|
|
|
|
```go
|
|
|
|
// RewardPeriod stores the state of an ongoing reward
|
|
type RewardPeriod struct {
|
|
Active bool `json:"active" yaml:"active"` // if the reward is active
|
|
CollateralType string `json:"collateral_type" yaml:"collateral_type"` // the collateral type for which rewards apply
|
|
Start time.Time `json:"start" yaml:"start"` // when the rewards start
|
|
End time.Time `json:"end" yaml:"end"` // when the rewards end
|
|
RewardsPerSecond sdk.Coin `json:"rewards_per_second" yaml:"rewards_per_second"` // per second reward payouts
|
|
}
|
|
```
|
|
|
|
Each `MultiRewardPeriod` defines a particular collateral for which one or more reward tokens are eligible and the amount of rewards available
|
|
|
|
```go
|
|
// MultiRewardPeriod supports multiple reward types
|
|
type MultiRewardPeriod struct {
|
|
Active bool `json:"active" yaml:"active"`
|
|
CollateralType string `json:"collateral_type" yaml:"collateral_type"`
|
|
Start time.Time `json:"start" yaml:"start"`
|
|
End time.Time `json:"end" yaml:"end"`
|
|
RewardsPerSecond sdk.Coins `json:"rewards_per_second" yaml:"rewards_per_second"` // per second reward payouts
|
|
}
|
|
```
|
|
|
|
`GenesisState` defines the state that must be persisted when the blockchain stops/restarts in order for normal function of the incentive module to resume.
|
|
|
|
```go
|
|
// GenesisState is the state that must be provided at genesis.
|
|
type GenesisState struct {
|
|
Params Params `json:"params" yaml:"params"` // governance parameters
|
|
USDXAccumulationTimes GenesisAccumulationTimes `json:"usdx_accumulation_times" yaml:"usdx_accumulation_times"` // when USDX rewards were last accumulated
|
|
HardSupplyAccumulationTimes GenesisAccumulationTimes `json:"hard_supply_accumulation_times" yaml:"hard_supply_accumulation_times"` // when hard supply rewards were last accumulated
|
|
HardBorrowAccumulationTimes GenesisAccumulationTimes `json:"hard_borrow_accumulation_times" yaml:"hard_borrow_accumulation_times"` // when hard borrow rewards were last accumulated
|
|
HardDelegatorAccumulationTimes GenesisAccumulationTimes `json:"hard_delegator_accumulation_times" yaml:"hard_delegator_accumulation_times"` // when hard delegator rewards were last accumulated
|
|
USDXMintingClaims USDXMintingClaims `json:"usdx_minting_claims" yaml:"usdx_minting_claims"` // USDX minting claims at genesis, if any
|
|
HardLiquidityProviderClaims HardLiquidityProviderClaims `json:"hard_liquidity_provider_claims" yaml:"hard_liquidity_provider_claims"` // Hard liquidity provider claims at genesis, if any
|
|
}
|
|
```
|
|
|
|
## Store

### Claim Creation
|
|
|
|
When users take incentivized actions, the `incentive` module will create or update a `Claim` object in the store, which represents the amount of rewards that the user is eligible to claim. The two defined claim objects are `USDXMintingClaims` and `HardLiquidityProviderClaims`:
|
|
|
|
```go
|
|
|
|
// BaseClaim is a common type shared by all Claims
|
|
type BaseClaim struct {
|
|
Owner sdk.AccAddress `json:"owner" yaml:"owner"`
|
|
Reward sdk.Coin `json:"reward" yaml:"reward"`
|
|
}
|
|
|
|
// BaseMultiClaim is a common type shared by all Claims with multiple reward denoms
|
|
type BaseMultiClaim struct {
|
|
Owner sdk.AccAddress `json:"owner" yaml:"owner"`
|
|
Reward sdk.Coins `json:"reward" yaml:"reward"`
|
|
}
|
|
|
|
// USDXMintingClaim is for USDX minting rewards
|
|
type USDXMintingClaim struct {
|
|
BaseClaim `json:"base_claim" yaml:"base_claim"` // Base claim object
|
|
RewardIndexes RewardIndexes `json:"reward_indexes" yaml:"reward_indexes"` // indexes which are used to calculate the amount of rewards a user can claim
|
|
}
|
|
|
|
// HardLiquidityProviderClaim stores the hard liquidity provider rewards that can be claimed by owner
|
|
type HardLiquidityProviderClaim struct {
|
|
BaseMultiClaim `json:"base_claim" yaml:"base_claim"` // base claim object
|
|
SupplyRewardIndexes MultiRewardIndexes `json:"supply_reward_indexes" yaml:"supply_reward_indexes"` // indexes which are used to calculate the amount of hard supply rewards a user can claim
|
|
BorrowRewardIndexes MultiRewardIndexes `json:"borrow_reward_indexes" yaml:"borrow_reward_indexes"` // indexes which are used to calculate the amount of hard borrow rewards a user can claim
|
|
DelegatorRewardIndexes RewardIndexes `json:"delegator_reward_indexes" yaml:"delegator_reward_indexes"` // indexes which are used to calculate the amount of hard delegator rewards a user can claim
|
|
}
|
|
```
