Functions ¶

func FlattenPayloadMessages ¶ added in v0.22.0

func FlattenPayloadMessages(payload gjson.Result) (gjson.Result, int, error)

FlattenPayloadMessages flattens the input payload's messages, representing them as key-value pairs of "msg{i}": {Msg}, rather than as an array of Msgs. We do this to support messages with different schemas.

func GetEIP712BytesForMsg ¶ added in v0.20.0

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

GetEIP712BytesForMsg returns the EIP-712 object bytes for the given SignDoc bytes by decoding the bytes into an EIP-712 object, then converting via WrapTxToTypedData. See https://eips.ethereum.org/EIPS/eip-712 for more.

func GetEIP712TypedDataForMsg ¶ added in v0.20.0

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

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

func LegacyGetEIP712BytesForMsg ¶ added in v0.22.0

func LegacyGetEIP712BytesForMsg(signDocBytes []byte) ([]byte, error)

LegacyGetEIP712BytesForMsg returns the EIP-712 object bytes for the given SignDoc bytes by decoding the bytes into an EIP-712 object, then converting via LegacyWrapTxToTypedData. See https://eips.ethereum.org/EIPS/eip-712 for more.

func LegacyGetEIP712TypedDataForMsg ¶ added in v0.22.0

func LegacyGetEIP712TypedDataForMsg(signDocBytes []byte) (apitypes.TypedData, error)

LegacyGetEIP712TypedDataForMsg returns the EIP-712 TypedData representation for either Amino or Protobuf encoded signature doc bytes.

func LegacyWrapTxToTypedData ¶ added in v0.22.0

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

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

func SetEncodingConfig ¶ added in v0.20.0

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(
	chainID uint64,
	data []byte,
) (apitypes.TypedData, error)

WrapTxToTypedData wraps an Amino-encoded Cosmos Tx JSON SignDoc bytestream into an EIP712-compatible TypedData request.

Types ¶

type FeeDelegationOptions ¶

type FeeDelegationOptions struct {
	FeePayer sdk.AccAddress
}
