Typescript library with support for the integration of Bitcoin for third party application, include the functionalities of generation of addresses and signed transactions.

Install

npm i @coolwallet/doge

Usage

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

const doge = new DOGE();

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 doge.getAddress(transport, appPrivateKey, appId, scriptType, 0);

const signTxData = {
    transport,
    appPrivateKey,
    appId,
    scriptType: 1,
    inputs: [{
        preTxHash: "735153f57da91462a01c17937a397aa67f7b5faf9ab74ebcdd4c8f485aba26f5",
        preIndex: 1,
        preValue: "87302",
        sequence: 0xFFFFFFFF,
        addressIndex: 0,
        pubkeyBuf: Uint8Array(33)
    }],
    output: {
        value: "10000",
        address: "3442qW39131y5Q8qR963ehjmxXPAXUWn7Q",
    },
    change: {
        value: "77301.99983500001",
        addressIndex: 0,
        pubkeyBuf: Uint8Array(33)
    }
}

const normalTx = await doge.signTransaction(signTxData)

Methods

getAddress

Description

Get address by address index.

The DOGE address generated is compatible to BIP141 (SegWit Proposal) and BIP44 with account and change set to 0, which means calling getAddress with addressIndex = i will get the address of folllowing path:

m/44'/3'/0'/0/{i}

In the design of current hardware, we only support path m/44'/3'/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.
