Implementation - BCS

bcsToBytes

bcsToBytes(): Uint8Array
Serializes a Serializable value to its BCS representation. This function is the TypeScript SDK equivalent of bcs::to_bytes in Move.

Returns Uint8Array
the BCS representation of the Serializable instance as a byte buffer.
Inherited from Signature.bcsToBytes
- Defined in src/bcs/serializer.ts:33

bcsToHex

bcsToHex(): Hex
Converts the BCS-serialized bytes of a value into a Hex instance. This function provides a Hex representation of the BCS-serialized data for easier handling and manipulation.

Returns Hex
A Hex instance with the BCS-serialized bytes loaded into its underlying Uint8Array.
Inherited from Signature.bcsToHex
- Defined in src/bcs/serializer.ts:46

Implementation - Serialization

constructor

new Secp256k1Signature(hexInput): Secp256k1Signature
Create a new Signature instance from a Uint8Array or String.
Parameters
- hexInput: HexInput
  A HexInput (string or Uint8Array)
Returns Secp256k1Signature
Overrides Signature.constructor
- Defined in src/core/crypto/secp256k1.ts:387

`Static` `Readonly`LENGTH

LENGTH = 64

Secp256k1 ecdsa signatures are 256-bit.

toString

toString(): string
Get the signature as a hex string with a 0x prefix e.g. 0x123456...

Returns string
The hex string representation of the signature.
Inherited from Signature.toString
- Defined in src/core/crypto/signature.ts:29

toUint8Array

toUint8Array(): Uint8Array
Get the raw signature bytes

Returns Uint8Array
Overrides Signature.toUint8Array
- Defined in src/core/crypto/secp256k1.ts:402

Methods

serialize

serialize(serializer): void
Parameters
- serializer: Serializer
Returns void
Overrides Signature.serialize
- Defined in src/core/crypto/secp256k1.ts:410

toStringWithoutPrefix

toStringWithoutPrefix(): string
Returns the hex string representation of the Serializable value without the 0x prefix.

Returns string
the hex format as a string without 0x prefix.
Inherited from Signature.toStringWithoutPrefix
- Defined in src/bcs/serializer.ts:55

`Static`deserialize

deserialize(deserializer): Secp256k1Signature
Parameters
- deserializer: Deserializer
Returns Secp256k1Signature
