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 ¶ added in v0.5.0
func NewAnteHandler(options HandlerOptions) sdk.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 storetypes.GasMeter, sig signing.SignatureV2, params authtypes.Params, ) error
SigVerificationGasConsumer is the Cosmos EVM 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)
- secp256k1 (Cosmos keys)
- ed25519 (Validators)
- multisig (Cosmos SDK multisigs)
Types ¶
type HandlerOptions ¶ added in v0.4.0
type HandlerOptions struct {
Cdc codec.BinaryCodec
AccountKeeper anteinterfaces.AccountKeeper
BankKeeper anteinterfaces.BankKeeper
IBCKeeper *ibckeeper.Keeper
FeeMarketKeeper anteinterfaces.FeeMarketKeeper
EvmKeeper anteinterfaces.EVMKeeper
FeegrantKeeper ante.FeegrantKeeper
ExtensionOptionChecker ante.ExtensionOptionChecker
SignModeHandler *txsigning.HandlerMap
SigGasConsumer func(meter storetypes.GasMeter, sig signing.SignatureV2, params authtypes.Params) error
MaxTxGasWanted uint64
// use dynamic fee checker or the cosmos-sdk default one for native transactions
DynamicFeeChecker bool
PendingTxListener PendingTxListener
}
HandlerOptions defines the list of module keepers required to run the Cosmos EVM AnteHandler decorators.
func (HandlerOptions) Validate ¶ added in v0.4.0
func (options HandlerOptions) Validate() error
Validate checks if the keepers are defined
type PendingTxListener ¶ added in v0.4.0
type TxListenerDecorator ¶ added in v0.4.0
type TxListenerDecorator struct {
// contains filtered or unexported fields
}
func NewTxListenerDecorator ¶ added in v0.4.0
func NewTxListenerDecorator(pendingTxListener PendingTxListener) TxListenerDecorator
NewTxListenerDecorator creates a new TxListenerDecorator with the provided PendingTxListener. CONTRACT: must be put at the last of the chained decorators
