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 Serializable.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 Serializable.bcsToHex
- Defined in src/bcs/serializer.ts:46

Implementation - Serialization

constructor

new Secp256k1PrivateKey(
hexInput: HexInput,
strict?: boolean,
): Secp256k1PrivateKey
Create a new PrivateKey instance from a Uint8Array or String.

Parameters
- hexInput: HexInput
  A HexInput (string or Uint8Array)
- Optionalstrict: boolean
  If true, private key must AIP-80 compliant.
Returns Secp256k1PrivateKey
Overrides Serializable.constructor
- Defined in src/core/crypto/secp256k1.ts:212

`Static` `Readonly`LENGTH

LENGTH: number = 32

Length of Secp256k1 ecdsa private key

publicKey

publicKey(): Secp256k1PublicKey
Derive the Secp256k1PublicKey from this private key.

Returns Secp256k1PublicKey
Secp256k1PublicKey The derived public key.
Implementation of PrivateKey.publicKey
- Defined in src/core/crypto/secp256k1.ts:303

sign

sign(message: HexInput): Secp256k1Signature
Sign the given message with the private key. This function generates a cryptographic signature for the provided message, ensuring the signature is canonical and non-malleable.
Parameters
- message: HexInput
  A message in HexInput format to be signed.
Returns Secp256k1Signature
Signature - The generated signature for the provided message.
Implementation of PrivateKey.sign
- Defined in src/core/crypto/secp256k1.ts:288

toString

toString(): string
Get the private key as a string representation.

Returns string
string representation of the private key
Overrides Serializable.toString
- Defined in src/core/crypto/secp256k1.ts:326

toUint8Array

toUint8Array(): Uint8Array
Get the private key in bytes (Uint8Array).

Returns Uint8Array
Implementation of PrivateKey.toUint8Array
- Defined in src/core/crypto/secp256k1.ts:315

`Static`fromDerivationPath

fromDerivationPath(path: string, mnemonics: string): Secp256k1PrivateKey
Derives a private key from a mnemonic seed phrase using a specified BIP44 path.
Parameters
- path: string
  The BIP44 path to derive the key from.
- mnemonics: string
  The mnemonic seed phrase used for key generation.
Returns Secp256k1PrivateKey
The generated private key.

Throws
Error if the provided path is not a valid BIP44 path.
- Defined in src/core/crypto/secp256k1.ts:247

`Static`generate

generate(): Secp256k1PrivateKey
Generate a new random private key.

Returns Secp256k1PrivateKey
Secp256k1PrivateKey - A newly generated Secp256k1 private key.
- Defined in src/core/crypto/secp256k1.ts:230

`Static`isPrivateKey

isPrivateKey(privateKey: PrivateKey): privateKey is Secp256k1PrivateKey
Determines if the provided private key is an instance of Secp256k1PrivateKey.
Parameters
- privateKey: PrivateKey
  The private key to be checked.
Returns privateKey is Secp256k1PrivateKey
Deprecated
use instanceof Secp256k1PrivateKey instead
- Defined in src/core/crypto/secp256k1.ts:374

Methods

serialize

serialize(serializer: Serializer): void
Parameters
- serializer: Serializer
Returns void
Overrides Serializable.serialize

toAIP80String

toAIP80String(): string
Get the private key as a AIP-80 compliant hex string.

Read about AIP-80

Returns string
AIP-80 compliant string representation of the private key.
- Defined in src/core/crypto/secp256k1.ts:346

toHexString

toHexString(): string
Get the private key as a hex string with the 0x prefix.

Returns string
string representation of the private key.
- Defined in src/core/crypto/secp256k1.ts:335

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 Serializable.toStringWithoutPrefix
- Defined in src/bcs/serializer.ts:55

`Static`deserialize

deserialize(deserializer: Deserializer): Secp256k1PrivateKey
Parameters
- deserializer: Deserializer
Returns Secp256k1PrivateKey
