type HandlerOptions ¶

type HandlerOptions struct {
	ante.HandlerOptions
	IBCKeeper                  *ibckeeper.Keeper
	BypassMinFeeMsgTypes       []string
	MaxBypassMinFeeMsgGasUsage string
}

HandlerOptions extend the SDK's AnteHandler options by requiring the IBC channel keeper.

func (h HandlerOptions) GetMaxBypassMinFeeMsgGasUsage() uint64

type MempoolFeeDecorator ¶

type MempoolFeeDecorator struct {
	BypassMinFeeMsgTypes       []string
	MaxBypassMinFeeMsgGasUsage uint64
}

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(bypassMsgTypes []string, MaxBypassMinFeeMsgGasUsage uint64) MempoolFeeDecorator

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