Types

type Minter

type Minter struct {
	RemainedTokens sdk.Coins `json:"remained_tokens" yaml:"remained_tokens"`
}

Minter represents the minting state.

func DefaultInitialMinter

func DefaultInitialMinter() Minter

DefaultInitialMinter returns a default initial Minter object for a new chain which uses an inflation rate of 13%.

func InitialMinter

func InitialMinter(inflation sdk.Dec) Minter

InitialMinter returns an initial Minter object with a given inflation value.

func NewMinter

func NewMinter(inflation, annualProvisions sdk.Dec) Minter

NewMinter returns a new Minter object with the given inflation and annual provisions values.

type Params

type Params struct {
	MintDenom              string `json:"mint_denom" yaml:"mint_denom"`
	UnfreezeAmountPerBlock int64  `json:"unfreeze_amount_per_block" yaml:"unfreeze_amount_per_block"`
}

mint parameters

func DefaultParams

func DefaultParams() Params

default minting module parameters

func NewParams

func NewParams(mintDenom string, unfreezeAmountPerBlock int64) Params

func (*Params) ParamSetPairs

func (p *Params) ParamSetPairs() params.ParamSetPairs

Implements params.ParamSet

func (Params) String

func (p Params) String() string

type SupplyKeeper

type SupplyKeeper interface {
	GetModuleAddress(name string) sdk.AccAddress

	// TODO remove with genesis 2-phases refactor https://github.com/cosmos/cosmos-sdk/issues/2862
	SetModuleAccount(sdk.Context, exported.ModuleAccountI)

	SendCoinsFromModuleToAccount(ctx sdk.Context, senderModule string, recipientAddr sdk.AccAddress, amt sdk.Coins) sdk.Error
	SendCoinsFromModuleToModule(ctx sdk.Context, senderModule, recipientModule string, amt sdk.Coins) sdk.Error
	MintCoins(ctx sdk.Context, name string, amt sdk.Coins) sdk.Error
}

SupplyKeeper defines the expected supply keeper
