isMerkleTreeType

▸ isMerkleTreeType(type): type is StarknetMerkleType

Checks if the given Starknet type is a Merkle tree type.

Parameters

Name	Type	Description
type	StarknetType	The StarkNet type to check.

getDependencies

▸ getDependencies(types, type, dependencies?, contains?, revision?): string[]

Get the dependencies of a struct type. If a struct has the same dependency multiple times, it's only included once in the resulting array.

Parameters

Name	Type	Default value
types	Record<string, StarknetType[]>	undefined
type	string	undefined
dependencies	string[]	[]
contains	string	''
revision	TypedDataRevision	Revision.LEGACY

Returns

string[]

src/utils/typedData.ts:131

---

encodeType

▸ encodeType(types, type, revision?): string

Encode a type to a string. All dependent types are alphabetically sorted.

Parameters

Name	Type	Default value
types	Record<string, StarknetType[]>	undefined
type	string	undefined
revision	TypedDataRevision	Revision.LEGACY

Returns

string

Defined in

src/utils/typedData.ts:189

getTypeHash

▸ getTypeHash(types, type, revision?): string

Get a type string as hash.

Parameters

Name	Type	Default value
types	Record<string, StarknetType[]>	undefined
type	string	undefined
revision	TypedDataRevision	Revision.LEGACY

Returns

string

Defined in

src/utils/typedData.ts:234

encodeValue

▸ encodeValue(types, type, data, ctx?, revision?): [string, string]

Encodes a single value to an ABI serialisable string, number or Buffer. Returns the data as tuple, which consists of an array of ABI compatible types, and an array of corresponding values.

Parameters

types	Record<string, StarknetType[]>	undefined
type	string	undefined
data	unknown	undefined
ctx	Context	{}
revision	TypedDataRevision	Revision.LEGACY

Returns

[string, string]

Defined in

src/utils/typedData.ts:246

encodeData

▸ encodeData<T>(types, type, data, revision?): string[][]

Encode the data to an ABI encoded Buffer. The data should be a key -> value object with all the required values. All dependent types are automatically encoded.

Type parameters

Name	Type
T	extends TypedData

Parameters

Name	Type	Default value
types	T["types"]	undefined
type	string	undefined
data	T["message"]	undefined
revision	TypedDataRevision	Revision.LEGACY

Returns

string[][]

getStructHash

▸ getStructHash<T>(types, type, data, revision?): string

Get encoded data as a hash. The data should be a key -> value object with all the required values. All dependent types are automatically encoded.

Type parameters

Name	Type
T	extends TypedData

Parameters

Name	Type	Default value
types	T["types"]	undefined
type	string	undefined
data	T["message"]	undefined
revision	TypedDataRevision	Revision.LEGACY

Returns

string

Defined in

getMessageHash

▸ getMessageHash(typedData, account): string

Get the SNIP-12 encoded message to sign, from the typedData object.

Parameters

Name	Type
typedData	TypedData
account	BigNumberish

Returns

string
