Functions

func CalculateDecreasingFactor

func CalculateDecreasingFactor(coinInfo types.Coin, amountInCollector sdkmath.Int, amountToBurn sdkmath.Int) sdk.Dec

Helper function for slashing in validator module CalculateDecreasingFactor checks future parameters for coin burn

func EndBlocker

Types

type Keeper

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

Keeper maintains the link to data storage and exposes getter/setter methods for the various parts of the state machine.

func NewKeeper

func NewKeeper(
	cdc codec.BinaryCodec,
	storeKey store.StoreKey,
	ps paramtypes.Subspace,
	ac auth.AccountKeeperI,
	fk feeTypes.FeeMarketKeeper,
	bk bank.Keeper,
) *Keeper

NewKeeper creates new Keeper instance.

func (Keeper) BurnCoin

func (k Keeper) BurnCoin(goCtx context.Context, msg *types.MsgBurnCoin) (*types.MsgBurnCoinResponse, error)

func (*Keeper) BurnPoolCoins

func (k *Keeper) BurnPoolCoins(ctx sdk.Context, poolName string, coins sdk.Coins) error

Special burn mainly for slashing in validator module It decrease both volume and reserve pool must be exists and must have burning right

func (Keeper) BuyCoin

func (k Keeper) BuyCoin(goCtx context.Context, msg *types.MsgBuyCoin) (*types.MsgBuyCoinResponse, error)

func (Keeper) Check

func (k Keeper) Check(c context.Context, req *types.QueryCheckRequest) (*types.QueryCheckResponse, error)

func (*Keeper) CheckFutureChanges

func (k *Keeper) CheckFutureChanges(ctx sdk.Context, coinInfo types.Coin, amount sdkmath.Int) error

Check than buy/sell/fee deduct operations will not violate coin constants: minimal volume, limit volume, minimal reserve It includes check balance of auth.FeeCollectorName Positive amount = buy = increase volume and reserve Negative amount = sell/deduct = decrease volume and reserve

func (*Keeper) CheckFutureVolumeChanges

func (k *Keeper) CheckFutureVolumeChanges(ctx sdk.Context, coinInfo types.Coin, amount sdkmath.Int) error

same as above, but check only volume need for burn operation, because this doest not change reserve
