Functions

func DeductFees 

func DeductFees(txFeesKeeper types.TxFeesKeeper, bankKeeper types.BankKeeper, ctx sdk.Context, acc authtypes.AccountI, fees sdk.Coins) error

DeductFees deducts fees from the given account and transfers them to the set module account.

Types

type DeductFeeDecorator 

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

DeductFeeDecorator deducts fees from the first signer of the tx. If the first signer does not have the funds to pay for the fees, we return an InsufficientFunds error. We call next AnteHandler if fees successfully deducted.

CONTRACT: Tx must implement FeeTx interface to use DeductFeeDecorator

func NewDeductFeeDecorator 

func NewDeductFeeDecorator(tk Keeper, ak types.AccountKeeper, bk types.BankKeeper, fk types.FeegrantKeeper) DeductFeeDecorator

func (DeductFeeDecorator) AnteHandle 

func (dfd DeductFeeDecorator) AnteHandle(ctx sdk.Context, tx sdk.Tx, simulate bool, next sdk.AnteHandler) (newCtx sdk.Context, err error)

type Hooks 

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

Hooks wrapper struct for incentives keeper

func (Hooks) AfterEpochEnd 

func (h Hooks) AfterEpochEnd(ctx sdk.Context, epochIdentifier string, epochNumber int64) error

func (Hooks) BeforeEpochStart 

func (h Hooks) BeforeEpochStart(ctx sdk.Context, epochIdentifier string, epochNumber int64) error

type Keeper 

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

func NewKeeper 

func NewKeeper(
	accountKeeper types.AccountKeeper,
	bankKeeper types.BankKeeper,
	storeKey sdk.StoreKey,
	poolManager types.PoolManager,
	spotPriceCalculator types.SpotPriceCalculator,
	protorevKeeper types.ProtorevKeeper,
	distributionKeeper types.DistributionKeeper,
	dataDir string,
) Keeper

func (Keeper) AfterEpochEnd 

func (k Keeper) AfterEpochEnd(ctx sdk.Context, epochIdentifier string, epochNumber int64) error

at the end of each epoch, swap all non-OSMO fees into the desired denom and send either to fee collector or community pool. Staking fee collector for staking rewards. - All non-native rewards that have a pool with liquidity and a link set in protorev get swapped to native denom - All resulting native tokens get sent to the fee collector. - Any non-native tokens that did not have associated pool stay in the balance of staking fee collector. Community pool fee collector. - All non-native rewards that have a pool with liquidity and a link set in protorev get swapped to a denom configured by parameter. - All resulting parameter denom tokens get sent to the community pool. - Any non-native tokens that did not have associated pool stay in the balance of community pool fee collector.

func (Keeper) BeforeEpochStart 

func (k Keeper) BeforeEpochStart(ctx sdk.Context, epochIdentifier string, epochNumber int64) error

func (Keeper) CalcFeeSpotPrice 

func (k Keeper) CalcFeeSpotPrice(ctx sdk.Context, inputDenom string) (osmomath.BigDec, error)

CalcFeeSpotPrice converts the provided tx fees into their equivalent value in the base denomination. Spot Price Calculation: spotPrice / (1 - spreadFactor), where spotPrice is defined as: (tokenBalanceIn / tokenWeightIn) / (tokenBalanceOut / tokenWeightOut)

func (Keeper) ConvertToBaseToken 

func (k Keeper) ConvertToBaseToken(ctx sdk.Context, inputFee sdk.Coin) (sdk.Coin, error)

ConvertToBaseToken converts a fee amount in a whitelisted fee token to the base fee token amount.

func (Keeper) ExportGenesis 

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

ExportGenesis returns the txfees module's exported genesis.

func (Keeper) GetBaseDenom 

func (k Keeper) GetBaseDenom(ctx sdk.Context) (denom string, err error)

GetFeeToken returns the fee token record for a specific denom, In our case the baseDenom is uosmo.

func (Keeper) GetFeeToken 

func (k Keeper) GetFeeToken(ctx sdk.Context, denom string) (types.FeeToken, error)

GetFeeToken returns a unique fee token record for a specific denom. If the denom doesn't exist, returns an error.

func (Keeper) GetFeeTokens 

func (k Keeper) GetFeeTokens(ctx sdk.Context) (feetokens []types.FeeToken)

func (Keeper) GetFeeTokensStore 

func (k Keeper) GetFeeTokensStore(ctx sdk.Context) sdk.KVStore

func (Keeper) HandleUpdateFeeTokenProposal 

func (k Keeper) HandleUpdateFeeTokenProposal(ctx sdk.Context, p *types.UpdateFeeTokenProposal) error

func (Keeper) Hooks 

func (k Keeper) Hooks() Hooks

Return the wrapper struct

func (Keeper) InitGenesis 

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

InitGenesis initializes the txfees module's state from a provided genesis state.

func (Keeper) IsSufficientFee 

func (k Keeper) IsSufficientFee(ctx sdk.Context, minBaseGasPrice osmomath.Dec, gasRequested uint64, feeCoin sdk.Coin) error

IsSufficientFee checks if the feeCoin provided (in any asset), is worth enough osmo at current spot prices to pay the gas cost of this tx.

func (Keeper) Logger 

func (k Keeper) Logger(ctx sdk.Context) log.Logger

func (Keeper) SetBaseDenom 

func (k Keeper) SetBaseDenom(ctx sdk.Context, denom string) error

SetBaseDenom sets the base fee denom for the chain. Should only be used once.

func (Keeper) SetFeeTokens 

func (k Keeper) SetFeeTokens(ctx sdk.Context, feetokens []types.FeeToken) error

func (Keeper) ValidateFeeToken 

func (k Keeper) ValidateFeeToken(ctx sdk.Context, feeToken types.FeeToken) error

ValidateFeeToken validates that a fee token record is valid It checks: - The denom exists - The denom is not the base denom - The gamm pool exists - The gamm pool includes the base token and fee token.

type MempoolFeeDecorator 

type MempoolFeeDecorator struct {
	TxFeesKeeper Keeper
	Opts         types.MempoolFeeOptions
}

MempoolFeeDecorator will check if the transaction's fee is at least as large as the local validator's minimum gasFee (defined in validator config). If fee is too low, decorator returns error and tx is rejected from mempool. Note this only applies when ctx.CheckTx = true If fee is high enough or not CheckTx, then call next AnteHandler CONTRACT: Tx must implement FeeTx to use MempoolFeeDecorator.

func NewMempoolFeeDecorator 

func NewMempoolFeeDecorator(txFeesKeeper Keeper, opts types.MempoolFeeOptions) MempoolFeeDecorator

func (MempoolFeeDecorator) AnteHandle 

func (mfd MempoolFeeDecorator) AnteHandle(ctx sdk.Context, tx sdk.Tx, simulate bool, next sdk.AnteHandler) (newCtx sdk.Context, err error)

func (MempoolFeeDecorator) GetMinBaseGasPriceForTx 

func (mfd MempoolFeeDecorator) GetMinBaseGasPriceForTx(ctx sdk.Context, baseDenom string, tx sdk.FeeTx) osmomath.Dec
