Functions

func ConsumeMultisignatureVerificationGas

func ConsumeMultisignatureVerificationGas(
	meter storetypes.GasMeter, sig *signing.MultiSignatureData, pubkey multisig.PubKey,
	params authtypes.Params, accSeq uint64,
) error

ConsumeMultisignatureVerificationGas consumes gas from a GasMeter for verifying a multisig pubkey signature

func NewAnteHandler

func NewAnteHandler(opts HandlerOptions) (sdk.AnteHandler, error)

NewAnteHandler returns an 'AnteHandler' that will run actions before a tx is sent to a module's handler.

func Recover

func Recover(logger tmlog.Logger, err *error)

func SigVerificationGasConsumer

func SigVerificationGasConsumer(
	meter storetypes.GasMeter, sig signing.SignatureV2, params authtypes.Params,
) error

SigVerificationGasConsumer consumes gas for signature verification based upon the public key type. The cost is fetched from the given params and is matched by the concrete type. The types of keys supported are:

- ethsecp256k1 (Ethereum keys)

- ed25519 (Validators)

- secp256k1, secp256r1 (default Cosmos SDK keys)

- multisig (Cosmos SDK multisigs)

Types

type HandlerOptions

type HandlerOptions struct {
	ExtensionOptionChecker authante.ExtensionOptionChecker
	FeegrantKeeper         authante.FeegrantKeeper
	SignModeHandler        *txsigning.HandlerMap
	SigGasConsumer         authante.SignatureVerificationGasConsumer

	AccountKeeper         evmtypes.AccountKeeper
	BankKeeper            evmtypes.BankKeeper
	Codec                 codec.BinaryCodec

	TXCounterStoreService corestoretypes.KVStoreService
	WasmConfig            *wasmtypes.WasmConfig
}

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

type MinGasPriceDecorator

type MinGasPriceDecorator struct {
	BypassMinFeeMsgTypes []string
	// contains filtered or unexported fields
}

MinGasPriceDecorator will check if the transaction's fee is at least as large as the MinGasPrices param. If fee is too low, decorator returns error and tx is rejected. This applies for both CheckTx and DeliverTx If fee is high enough, then call next AnteHandler CONTRACT: Tx must implement FeeTx to use MinGasPriceDecorator

func NewMinGasPriceDecorator

func NewMinGasPriceDecorator(fk ethermintante.FeeMarketKeeper, ek ethermintante.EVMKeeper, bypassMsgTypes []string) MinGasPriceDecorator

func (MinGasPriceDecorator) AnteHandle

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