Types

type Keeper 

type Keeper struct {
	// contains filtered or unexported fields
}

Keeper of the liquidstaking store

func NewKeeper

	accountKeeper types.AccountKeeper, bankKeeper types.BankKeeper, stakingKeeper types.StakingKeeper,
	distrKeeper types.DistrKeeper, slashingKeeper types.SlashingKeeper,
) Keeper

NewKeeper returns a liquidstaking keeper. It handles: - creating new ModuleAccounts for each pool ReserveAccount - sending to and from ModuleAccounts - minting, burning PoolCoins

func (Keeper) CheckDelegationStates 

func (k Keeper) CheckDelegationStates(ctx sdk.Context, proxyAcc sdk.AccAddress) (sdk.Dec, sdk.Dec, math.Int)

CheckDelegationStates returns total remaining rewards, delshares, liquid tokens of delegations by proxy account

func (Keeper) ExportGenesis 

func (k Keeper) ExportGenesis(ctx sdk.Context) *types.GenesisState

ExportGenesis returns the liquidstaking module's genesis state.

func (Keeper) GetActiveLiquidValidators 

func (k Keeper) GetActiveLiquidValidators(ctx sdk.Context, whitelistedValsMap types.WhitelistedValsMap) (vals types.ActiveLiquidValidators)

GetActiveLiquidValidators get the set of active liquid validators.

func (Keeper) GetAllLiquidValidatorStates 

func (k Keeper) GetAllLiquidValidatorStates(ctx sdk.Context) (liquidValidatorStates []types.LiquidValidatorState)

func (Keeper) GetAllLiquidValidators 

func (k Keeper) GetAllLiquidValidators(ctx sdk.Context) (vals types.LiquidValidators)

GetAllLiquidValidators get the set of all liquid validators with no limits, used during genesis dump

func (Keeper) GetCodec 

func (k Keeper) GetCodec() codec.BinaryCodec

GetCodec return codec.Codec object used by the keeper

func (Keeper) GetLiquidValidator 

func (k Keeper) GetLiquidValidator(ctx sdk.Context, addr sdk.ValAddress) (val types.LiquidValidator, found bool)

GetLiquidValidator get a single liquid validator

func (Keeper) GetLiquidValidatorState 

func (k Keeper) GetLiquidValidatorState(ctx sdk.Context, addr sdk.ValAddress) (liquidValidatorState types.LiquidValidatorState, found bool)

func (Keeper) GetNetAmountState 

func (k Keeper) GetNetAmountState(ctx sdk.Context) (nas types.NetAmountState)

GetNetAmountState calculates the sum of bondedDenom balance, total delegation tokens(slash applied LiquidTokens), total remaining reward of types.LiquidStakingProxyAcc During liquid unstaking, btoken immediately burns and the unbonding queue belongs to the requester, so the liquid staker's unbonding values are excluded on netAmount It is used only for calculation and query and is not stored in kv.

func (Keeper) GetParams 

func (k Keeper) GetParams(ctx sdk.Context) (params types.Params)

GetParams gets the parameters for the liquidstaking module.

func (Keeper) GetProxyAccBalance 

func (k Keeper) GetProxyAccBalance(ctx sdk.Context, proxyAcc sdk.AccAddress) (balance sdk.Coin)

func (Keeper) GetWeightMap 

func (k Keeper) GetWeightMap(ctx sdk.Context, liquidVals types.LiquidValidators, whitelistedValsMap types.WhitelistedValsMap) (map[string]math.Int, math.Int)

func (Keeper) InitGenesis 

func (k Keeper) InitGenesis(ctx sdk.Context, genState types.GenesisState)

InitGenesis initializes the liquidstaking module's state from a given genesis state.

func (Keeper) IsActiveLiquidValidator 

func (k Keeper) IsActiveLiquidValidator(ctx sdk.Context, lv types.LiquidValidator, whitelistedValsMap types.WhitelistedValsMap) bool

func (Keeper) IsTombstoned 

func (k Keeper) IsTombstoned(ctx sdk.Context, val stakingtypes.Validator) bool
