Functions

func ConsumeMultisignatureVerificationGas

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

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

func NewAnteHandler

func NewAnteHandler(app *baseapp.BaseApp, options AnteDecorators) cosmos.AnteHandler

NewAnteHandler returns an ante handler responsible for attempting to route an Ethereum or SDK transaction to an internal ante handler for performing transaction-level processing (e.g. fee payment, signature verification) before being passed onto it's respective handler.

func SigVerificationGasConsumer

func SigVerificationGasConsumer(
	meter cosmos.GasMeter, sig signing.SignatureV2, params authmodule.Params,
) error

SigVerificationGasConsumer is the Artela implementation of SignatureVerificationGasConsumer. It 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)

- multisig (Cosmos SDK multisigs)

Types

AnteDecorators defines the list of module keepers required to run the Artela AnteHandler decorators.

func (AnteDecorators) Validate

func (options AnteDecorators) Validate() error

Validate checks if the keepers are defined
