Usage

import KAS from '@coolwallet/kas';
import { crypto } from '@coolwallet/core';
import { createTransport } from '@coolwallet/transport-web-ble';

const kas = new KAS();

const transport = await createTransport();

const { privateKey: appPrivateKey } = crypto.key.generateKeyPair();

const appId = 'appId that had been registered by wallet';

const addressIndex = 0;

const address = await kas.getAddress(transport, appPrivateKey, appId, scriptType, 0);

// TODO implement

Methods

getAddress

Description

Get address by address index.

The KAS address generated is compatible to BIP44 and Base32 with account and change set to 0, which means calling getAddress with addressIndex = i will get the address of folllowing path:

m/44'/111111'/0'/0/{i}

In the design of current hardware, we only support path m/44'/111111'/0'/0/{i} for speed optimization. This might change in the future and we will then open a more general interface to deal with custom path.

async getAddress(
    transport: Transport, 
    appPrivateKey: string, 
    appId: string, 
    scriptType: ScriptType, 
    addressIndex: number
): Promise<string>
