Functions

func GetEIP712BytesForMsg

func GetEIP712BytesForMsg(signDocBytes []byte) ([]byte, error)

Get the EIP-712 object bytes for the given SignDoc bytes by first decoding the bytes into an EIP-712 object, then hashing the EIP-712 object to create the bytes to be signed. See https://eips.ethereum.org/EIPS/eip-712 for more.

func GetEIP712TypedDataForMsg

func GetEIP712TypedDataForMsg(signDocBytes []byte) (apitypes.TypedData, error)

GetEIP712TypedDataForMsg returns the EIP-712 TypedData representation for either Amino or Protobuf encoded signature doc bytes.

func SetEncodingConfig

func SetEncodingConfig(cfg params.EncodingConfig)

SetEncodingConfig set the encoding config to the singleton codecs (Amino and Protobuf). The process of unmarshaling SignDoc bytes into a SignDoc object requires having a codec populated with all relevant message types. As a result, we must call this method on app initialization with the app's encoding config.

func WrapTxToTypedData

func WrapTxToTypedData(
	cdc codectypes.AnyUnpacker,
	chainID uint64,
	msg sdk.Msg,
	data []byte,
	feeDelegation *FeeDelegationOptions,
) (apitypes.TypedData, error)

WrapTxToTypedData is an ultimate method that wraps Amino-encoded Cosmos Tx JSON data into an EIP712-compatible TypedData request.

Types

type FeeDelegationOptions

type FeeDelegationOptions struct {
	FeePayer sdk.AccAddress
