Functions ¶
func DefaultSigVerificationGasConsumer ¶
func DefaultSigVerificationGasConsumer( meter sdk.GasMeter, sig signing.SignatureV2, params authtypes.Params, ) error
DefaultSigVerificationGasConsumer is the default 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.
func NewAnteHandler ¶
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 VerifySignature ¶
func VerifySignature( pubKey cryptotypes.PubKey, signerData authsigning.SignerData, sigData signing.SignatureData, _ authsigning.SignModeHandler, tx authsigning.Tx, chain string, wk wasmxkeeper.Keeper, ctx sdk.Context, verifyBtcSigPath string, ) error
VerifySignature verifies a transaction signature contained in SignatureData abstracting over different signing modes and single vs multi-signatures.
Types ¶
type Eip712SigVerificationDecorator ¶
type Eip712SigVerificationDecorator struct {
// contains filtered or unexported fields
}
Eip712SigVerificationDecorator Verify all signatures for a tx and return an error if any are invalid. Note, the Eip712SigVerificationDecorator decorator will not get executed on ReCheck.
CONTRACT: Pubkeys are set in context for all signers before this decorator runs CONTRACT: Tx must implement SigVerifiableTx interface
func NewEip712SigVerificationDecorator ¶
func NewEip712SigVerificationDecorator(ak ante.AccountKeeper, wk wasmxkeeper.Keeper, signModeHandler authsigning.SignModeHandler, chain string, verifyBtcSigPath string) Eip712SigVerificationDecorator
NewEip712SigVerificationDecorator creates a new Eip712SigVerificationDecorator
func (Eip712SigVerificationDecorator) AnteHandle ¶
func (svd Eip712SigVerificationDecorator) AnteHandle(ctx sdk.Context, tx sdk.Tx, simulate bool, next sdk.AnteHandler) (newCtx sdk.Context, err error)
AnteHandle handles validation of EIP712 signed cosmos txs. it is not run on RecheckTx
type HandlerOptions ¶
type HandlerOptions struct {
AccountKeeper ante.AccountKeeper
BankKeeper authtypes.BankKeeper
IBCKeeper *ibckeeper.Keeper
FeegrantKeeper ante.FeegrantKeeper
SignModeHandler authsigning.SignModeHandler
SigGasConsumer func(meter sdk.GasMeter, sig signing.SignatureV2, params authtypes.Params) error
TxFeeChecker ante.TxFeeChecker
WasmXKeeper wasmxkeeper.Keeper
VerifyBtcSigPath string
}
HandlerOptions extend the SDK's AnteHandler options by requiring the IBC channel keeper, EVM Keeper and Fee Market Keeper.
func (HandlerOptions) Validate ¶
func (options HandlerOptions) Validate() error
