type FeeMeterContextDecorator added in v1.8.0 

type FeeMeterContextDecorator struct{}

FeeMeterContextDecorator is an AnteDecorator that wraps the current context gas meter with a msg based fee meter. Also, it merges functionality from GasTracerContextDecorator in previous versions which provided an AnteDecorator that wraps the current context gas meter with one that outputs debug logging and telemetry whenever gas is consumed on the meter.

func NewFeeMeterContextDecorator added in v1.8.0 

func NewFeeMeterContextDecorator() FeeMeterContextDecorator

NewFeeMeterContextDecorator creates a new FeeMeterContextDecorator

type MsgFeesDecorator added in v1.8.0 

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

MsgFeesDecorator will check if the transaction's fee is at least as large as tax + additional minimum gasFee (defined in msgfeeskeeper) and record additional fee proceeds to msgfees module to track additional fee proceeds. 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 MsgFeesDecorator

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

AnteHandle handles msg fee checking has two functions ensures, 1. has enough fees to add to Mempool (this involves CheckTx) 2. Makes sure enough fees are present for additional message fees Let z be the Total Fees to be paid Let x be the Base gas Fees to be paid Let y is the additional fees to be paid per MsgType then z = x + y This Fee Decorator makes sure that z is >= to x + y

type ProvenanceDeductFeeDecorator added in v1.8.0 

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

ProvenanceDeductFeeDecorator deducts fees from the first signer of the tx If the first signer does not have the funds to pay for the fees, return with InsufficientFunds error Call next AnteHandler if fees successfully deducted CONTRACT: Tx must implement FeeTx interface to use ProvenanceDeductFeeDecorator

func NewProvenanceDeductFeeDecorator added in v1.8.0 

func NewProvenanceDeductFeeDecorator(ak authante.AccountKeeper, bk types.BankKeeper, fk msgfeestypes.FeegrantKeeper, mbfk msgfeestypes.MsgFeesKeeper) ProvenanceDeductFeeDecorator

func (ProvenanceDeductFeeDecorator) AnteHandle added in v1.8.0 

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

type TxGasLimitDecorator added in v1.8.0 

type TxGasLimitDecorator struct{}

TxGasLimitDecorator will check if the transaction's gas amount is higher than 5% of the maximum gas allowed per block. If gas is too high, decorator returns error and tx is rejected from mempool. If gas is below the limit, then call next AnteHandler CONTRACT: Tx must implement FeeTx to use TxGasLimitDecorator

func NewTxGasLimitDecorator added in v1.8.0 

func NewTxGasLimitDecorator() TxGasLimitDecorator

func (TxGasLimitDecorator) AnteHandle added in v1.8.0 

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