React Native TSS SDK

Access the API references for publicly exported classes and their respective methods.

The library exports three classes:

• The main class performs and manages all the TSS functionality. P1Tss

• The two helper classes are (P1PartyKeys and KeyshareP1) are input or output of P1Tss methods.

P1Tss methods

Key generation

static async keygen(
  base64SessionId: string,
  p1Keys: P1PartyKeys,
  apiUrl: string
): Promise<KeyshareP1>

• Performs key generation with TSS server node

• Accepts base64SessionId keygen session id in encode base64 string

• Accepts p1Keys key pair of the party

• Accepts apiUrl of the TSS server node

Signature

static async signParty(
  base64SessionId: string,
  keyshareP1: KeyshareP1,
  p1Keys: P1PartyKeys,
  base64MessageHash: string,
  chainPath: string = 'm',
  apiUrl: string
): Promise<string>;

• Generate signature

• Accepts base64SessionId sign session id in encode base64 string

• Accepts keyshareP1 key share of the party instance

• Accepts p1Keys key pair of the party instance

• Accepts base64MessageHash hash of the message to be signed in encode base64 string

• Accepts chainPath of the key to be used for signing

• Accepts apiUrl of the TSS server node

Key refresh

static async refreshKeygen(
  base64SessionId: string,
  p1Keys: P1PartyKeys,
  keyshare: KeyshareP1,
  apiUrl: string
): Promise<KeyshareP1>;

• Performs key refresh with TSS server node

• Accepts base64SessionId key-refresh session id in encode base64 string

• Accepts p1Keys key pair of the P1PartyKeys instance

• Accepts keyshare keyshare of the KeyshareP1 instance

• Accepts apiUrl of the TSS server node

P1PartyKeys methods

async extractPk(): Promise<string>;

Get

async messageSign(base64Message: string): Promise<string>;

• Message content in base64 encode string

KeyshareP1 methods

async getPublicKey(): Promise<string>;

Get key id of the key share

async getKeyId(): Promise<string>

Get base64 string representation of the key share

async toBase64String(): Promise<string>;

Create a key share from base64 string

static async fromBase64String(base64Keyshare: string): Promise<KeyshareP1>;

• Accepts base64Keyshare of the key share

Get the bytes representation of the key share

async toBytes(): Promise<Uint8Array>;

Create a key share from bytes

static async fromBytes(bytes: Uint8Array): Promise<KeyshareP1>;

• Accepts bytes of the key share
