minimal-slp-wallet

这是一款用于前端网络应用程序的极简主义比特币现金 (BCH) 钱包。 它是令牌感知的,与代码从以下分支的钱包不同:minimal-bch-wallet。 它旨在与 gatsby-ipfs-web-wallet 基于网络的钱包一起使用,以及 bch-js JavaScript 库fullstack.cash">FullStack.cash

钱包密钥对的默认推导路径是m/44'/245'/0'/0/0。 这是 SLP 令牌感知 BCH 钱包的 BIP44 标准。

Examples

examples 目录显示了如何编写使用此库的 node.js JavaScript 应用程序来与 BCH 一起工作:

How to use it?

Import

Add to your HTML scripts

<script src="https://unpkg.com/minimal-slp-wallet"></script>

Node module

npm install minimal-slp-wallet --save
// module import
import BchWallet from "minimal-slp-wallet";

// nodejs modules
const BchWallet = require("minimal-slp-wallet");

Create new wallets

const bchWallet = new BchWallet();
await bchWallet.walletInfoPromise // Wait for wallet to be created.

// 12 words seed phrase for the wallet
console.log(bchWallet.walletInfo.mnemonic);

// cash address derived from the seed (derivation path: m/44'/245'/0'/0/0)
console.log(bchWallet.walletInfo.cashAddress);

// legacy address derived from the seed (derivation path: m/44'/245'/0'/0/0)
console.log(bchWallet.walletInfo.legacyAddress);

// private key for the BCH address derived from the seed (derivation path: m/44'/245'/0'/0/0)
console.log(bchWallet.walletInfo.privateKey);

Mnemonic encryption

const bchWallet = new BchWallet(null, {
  password: "myStrongPassword"
});

// 12 words seed phrase for the wallet
console.log(bchWallet.walletInfo.mnemonic);

// encrypted mnemonic
console.log(bchWallet.walletInfo.mnemonicEncrypted);

const bchWallet2 = new BchWallet(bchWallet.walletInfo.mnemonicEncrypted, {
  password: "myStrongPassword"
});

// decrypted mnemonic
console.log(bchWallet2.walletInfo.mnemonic);

Initialize wallet with mnemonic

// initialize with 12 words seed phrase for the wallet
const bchWallet = new BchWallet("minor bench until split suffer shine series bag avoid cruel orient aunt");

// initialize for specific HD derivation path
const bchWallet2 = new BchWallet("minor bench until split suffer shine series bag avoid cruel orient aunt", {
    HdPath: "m/44'/245'/0'/1'"
});

Send transactions

您可以将资金发送到其他 BCH 钱包。 您可以通过简单地扩展接收器数组来将资金分配给 N 个用户。

const bchWallet = new BchWallet();

const receivers = [
    {
        address: "bitcoincash:qp2rmj8heytjrksxm2xrjs0hncnvl08xwgkweawu9h",
        // amount in satoshis, 1 satoshi = 0.00000001 Bitcoin
        amountSat: 100000
    }
];

const txid = await bchWallet.send(receivers);

// Transaction ID
// you can then see the transaction in one of the explorers
// example: `https://explorer.bitcoin.com/bch/tx/${tx.txid}`;
console.log(txid);

Send Tokens

您可以用类似的方式发送令牌:

const receiver = {
  address: "simpleledger:qpeq7xx5x3a2jfa0x0w8cjqp4v9cm842vgsjqwzvfk",
  tokenId: "a4fb5c2da1aa064e25018a43f9165040071d9e984ba190c222a7f59053af84b2",
  qty: 1.25
}

const txid = await bchWallet.sendTokens(receiver);

// Transaction ID
console.log(txid);

注意目前仅支持单个令牌发送。 即一种令牌类型 每个接收者每个交易。

Get Wallet Balance

获取 BCH 地址的余额(已确认 + 未确认)

// will get a balance for bchWallet.cashAddress
const myBalance = await bchWallet.getBalance();

// will get a balance for any address
const balanceOfOtherAddress = await bchWallet.getBalance("bitcoincash:qp2rmj8heytjrksxm2xrjs0hncnvl08xwgkweawu9h");

List Tokens

列出地址持有的 SLP 代币。

// will get token balance for bchWallet.cashAddress
const myBalance = await bchWallet.listTokens();

// will get a balance for any address
const balanceOfOtherAddress = await bchWallet.listTokens("simpleledger:qpeq7xx5x3a2jfa0x0w8cjqp4v9cm842vgsjqwzvfk");

Get Wallet Transaction History

获取涉及此钱包的交易的 TXID 数组。

// will get transaction history for bchWallet.cashAddress
const myTransactions = await bchWallet.getTransactions();

// will get transaction history for any address
const txHistoryOfOtherAddress = await bchWallet.getTransactions("bitcoincash:qp2rmj8heytjrksxm2xrjs0hncnvl08xwgkweawu9h");

Error Handling

try {
    tx = await bchWallet.send([
        { address: "bitcoincash:qrlhkg4d9z3y88j246a6482xzregxaxnfsagmd2kh3", amountSat: 1000 }
    ]);
} catch (err) {
    console.error(err);

    if (err.message && err.message.indexOf("Insufficient") > -1) {
        return alert("Insufficient balance on your BCH account.");
    }

    return alert("Error. Try again later.");
}

Save keys in the browser

在开发 BCH 应用程序时,请记住永远不要将私钥/助记词/助记词发送到您的服务器。

  1. Your servers can be hacked
  2. Depending on your jurisdiction you may not have the allowance to manage the funds of your users
const bchWallet1 = new BchWallet();

// save the mnemonic for later
localStorage.setItem("BCH_MNEMONIC", bchWallet1.walletInfo.mnemonic);

// retrieve mnemonic to initialize the wallet
const bchWallet2 = new BchWallet(localStorage.getItem("BCH_MNEMONIC"));

minimal-slp-wallet

This is a minimalist Bitcoin Cash (BCH) wallet for use with front end web apps. It's token aware, unlike the wallet the code is forked from: minimal-bch-wallet. It's intended to be used with the gatsby-ipfs-web-wallet web-based wallet, and the bch-js JavaScript library provided by FullStack.cash

The default derivation path for the wallet keypair is m/44'/245'/0'/0/0. This is the BIP44 standard for SLP token-aware BCH wallets.

Examples

The examples directory shows how to write node.js JavaScript apps that use this library to work with BCH:

How to use it?

Import

Add to your HTML scripts

<script src="https://unpkg.com/minimal-slp-wallet"></script>

Node module

npm install minimal-slp-wallet --save
// module import
import BchWallet from "minimal-slp-wallet";

// nodejs modules
const BchWallet = require("minimal-slp-wallet");

Create new wallets

const bchWallet = new BchWallet();
await bchWallet.walletInfoPromise // Wait for wallet to be created.

// 12 words seed phrase for the wallet
console.log(bchWallet.walletInfo.mnemonic);

// cash address derived from the seed (derivation path: m/44'/245'/0'/0/0)
console.log(bchWallet.walletInfo.cashAddress);

// legacy address derived from the seed (derivation path: m/44'/245'/0'/0/0)
console.log(bchWallet.walletInfo.legacyAddress);

// private key for the BCH address derived from the seed (derivation path: m/44'/245'/0'/0/0)
console.log(bchWallet.walletInfo.privateKey);

Mnemonic encryption

const bchWallet = new BchWallet(null, {
  password: "myStrongPassword"
});

// 12 words seed phrase for the wallet
console.log(bchWallet.walletInfo.mnemonic);

// encrypted mnemonic
console.log(bchWallet.walletInfo.mnemonicEncrypted);

const bchWallet2 = new BchWallet(bchWallet.walletInfo.mnemonicEncrypted, {
  password: "myStrongPassword"
});

// decrypted mnemonic
console.log(bchWallet2.walletInfo.mnemonic);

Initialize wallet with mnemonic

// initialize with 12 words seed phrase for the wallet
const bchWallet = new BchWallet("minor bench until split suffer shine series bag avoid cruel orient aunt");

// initialize for specific HD derivation path
const bchWallet2 = new BchWallet("minor bench until split suffer shine series bag avoid cruel orient aunt", {
    HdPath: "m/44'/245'/0'/1'"
});

Send transactions

You can send funds to other BCH wallets. You can distribute funds to N users by simply extending the receiver array.

const bchWallet = new BchWallet();

const receivers = [
    {
        address: "bitcoincash:qp2rmj8heytjrksxm2xrjs0hncnvl08xwgkweawu9h",
        // amount in satoshis, 1 satoshi = 0.00000001 Bitcoin
        amountSat: 100000
    }
];

const txid = await bchWallet.send(receivers);

// Transaction ID
// you can then see the transaction in one of the explorers
// example: `https://explorer.bitcoin.com/bch/tx/${tx.txid}`;
console.log(txid);

Send Tokens

You can send tokens in a similar way:

const receiver = {
  address: "simpleledger:qpeq7xx5x3a2jfa0x0w8cjqp4v9cm842vgsjqwzvfk",
  tokenId: "a4fb5c2da1aa064e25018a43f9165040071d9e984ba190c222a7f59053af84b2",
  qty: 1.25
}

const txid = await bchWallet.sendTokens(receiver);

// Transaction ID
console.log(txid);

Note: Only single token sends are supported at the moment. i.e. One token type per receiver per transaction.

Get Wallet Balance

Gets balance (confirmed + unconfirmed) for an BCH address

// will get a balance for bchWallet.cashAddress
const myBalance = await bchWallet.getBalance();

// will get a balance for any address
const balanceOfOtherAddress = await bchWallet.getBalance("bitcoincash:qp2rmj8heytjrksxm2xrjs0hncnvl08xwgkweawu9h");

List Tokens

List the SLP tokens held by an address.

// will get token balance for bchWallet.cashAddress
const myBalance = await bchWallet.listTokens();

// will get a balance for any address
const balanceOfOtherAddress = await bchWallet.listTokens("simpleledger:qpeq7xx5x3a2jfa0x0w8cjqp4v9cm842vgsjqwzvfk");

Get Wallet Transaction History

Get an array of TXIDs of the transactions involving this wallet.

// will get transaction history for bchWallet.cashAddress
const myTransactions = await bchWallet.getTransactions();

// will get transaction history for any address
const txHistoryOfOtherAddress = await bchWallet.getTransactions("bitcoincash:qp2rmj8heytjrksxm2xrjs0hncnvl08xwgkweawu9h");

Error Handling

try {
    tx = await bchWallet.send([
        { address: "bitcoincash:qrlhkg4d9z3y88j246a6482xzregxaxnfsagmd2kh3", amountSat: 1000 }
    ]);
} catch (err) {
    console.error(err);

    if (err.message && err.message.indexOf("Insufficient") > -1) {
        return alert("Insufficient balance on your BCH account.");
    }

    return alert("Error. Try again later.");
}

Save keys in the browser

While developing BCH apps, remember to never send the private keys / mnemonic / seed phrase to your servers.

  1. Your servers can be hacked
  2. Depending on your jurisdiction you may not have the allowance to manage the funds of your users
const bchWallet1 = new BchWallet();

// save the mnemonic for later
localStorage.setItem("BCH_MNEMONIC", bchWallet1.walletInfo.mnemonic);

// retrieve mnemonic to initialize the wallet
const bchWallet2 = new BchWallet(localStorage.getItem("BCH_MNEMONIC"));
