Functions

func ConsumeMultisignatureVerificationGas

func ConsumeMultisignatureVerificationGas(
	meter sdk.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)

func Recover

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

func SigVerificationGasConsumer

func SigVerificationGasConsumer(
	meter sdk.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 {
	AccountKeeper   evmtypes.AccountKeeper
	BankKeeper      evmtypes.BankKeeper
	IBCKeeper       *ibckeeper.Keeper
	FeegrantKeeper  authante.FeegrantKeeper
	SignModeHandler authsigning.SignModeHandler
	SigGasConsumer  authante.SignatureVerificationGasConsumer

	BypassMinFeeMsgTypes []string
	TxCounterStoreKey    sdk.StoreKey
	WasmConfig           wasmTypes.WasmConfig
}

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

type MempoolFeeDecorator

type MempoolFeeDecorator struct {
	BypassMinFeeMsgTypes []string
}

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(bypassMsgTypes []string) MempoolFeeDecorator

func (MempoolFeeDecorator) AnteHandle

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