WEB3 Wallet

npm i web3t

• Web3t is open source free covered by test library available for everyone and can be used to build an exchange, wallet and other crypto systems.
• Opened Standard. Everyone can contribute to add his coin.
• Used by WEB3 Wallet
• Partially Compatible with WEB3 Wallet
• Compatible with MetaMask Web3 Standard for Ethereum

• BTC (Bitcoin)
• LTC (Litecoin)
• ETH (Ethereum)
• DASH
• XEM (NEM)
• XRP (Ripple)
• [ANY_COIN]

var buildWeb3t = require('web3t');

Just pass the testnet word into constructor.

function testnet(err, web3t) {
    ... 

}

buildWeb3t("testnet", testnet);

There are other advanced possible ways to build the web3 object for case when you need to define a special testnet. It is useful for case when you have a lot of faucets of special testnet and write unit tests.

function testnet(err, web3t) {
    ... 

}

buildWeb3t("testnet, ropsten for eth", testnet);

function mainnet(err, web3t) {
    ... 
}

buildWeb3t("mainnet", mainnet);

function mainnet(err, web3t) {
    ... 
}

var config = {
   mode: "mainnet"
   plugins: {},
   providers: {}
}

buildWeb3t(config, mainnet);

web3t.eth.sendTransaction({ to, amount }, cb);

web3t.btc.sendTransaction({ to, amount }, cb);

web3t.zec.sendTransaction({ to, amount }, cb);

web3t.[ANY_COIN].sendTransaction({ to, amount }, cb);
  

Simplified Method to Send All Funds. Wrapper on sendTransaction

var cb => (err, tx) {
  
}

web3t.[ANY_COIN].sendAllFunds({ to, data }, cb);
  

You can create a lot of addresses by providing different index

var cb => (err, { address, privateKey, publicKey }) {
  
}

web3t.[ANY_COIN].createAccount({ mnemonic, index }, cb);
  

Get Balance by account object ({ address, privateKey }) Usually it does not need the private key but coins like monero needs decrypt data to read the balance

  var cb => (err, balance) {
  
  }

  web3t.[ANY_COIN].getBalance({ account }, cb);
  

List of all transactions. Same result structure for all coins

  
  var cb => (err, transactions) {
  
  }
  
  web3t.[ANY_COIN].getHistory({ account }, cb);
  

You need to define the default fee in plugin but for NEM, Monero and other coins you need to calculate the fee

  
  var cb => (err, amountFee) {
  
  }
  
  web3t.[ANY_COIN].calcFee({ account, to, amount, data}, cb); // => fee
  

This transaction consists of create, sign, push transaction

  var cb => (err, receipt) {
  
  }

  web3t.[ANY_COIN].createTransaction({ account, to, amount, data}, cb); // => tx

In some cases you need to have the hex of transaction before for some reason before you push it

  var cb => (err, rawtx) {
  
  }

  web3t.[ANY_COIN].signTransaction({ account, to, amount, data}, cb); // => rawtx

Push the signed transaction (hex) into blockchain

  var cb => (err, receipt) {
  
  }

  web3t.[ANY_COIN].pushTransaction(rawtx, cb); // => rawtx

sendTransaction and getBalance are compatible with WEB3 Wallet

You can find issues but we improve it daily. Please do not judge but help.

1. Please modify only plugins, providers, package.json
2. plugin should consists only network information and implements Interfaces/coin-interface.ts
3. provider should implements Interfaces/protocol-interface.ts
4. Send a pull request
5. Any question [email protected]

The management of different coins should be similar, so that there is no need for each to develop a new infrastructure, and connect it to the existing one

Web 3.0 is an inclusive set of protocols to provide building blocks for application makers. These building blocks take the place of traditional web technologies like HTTP, AJAX and MySQL, but present a whole new way of creating applications. These technologies give the user strong and verifiable guarantees about the information they are receiving, what information they are giving away, and what they are paying and what they are receiving in return. By empowering users to act for themselves within low-barrier markets, we can ensure censorship and monopolization have fewer places to hide. Consider Web 3.0 to be an executable Magna Carta — “the foundation of the freedom of the individual against the arbitrary authority of the despot.”

There was already implemented solution Web 3.0 in Metamask Wallet and used by dozen of dapps. It is great. But it is available only for ETH. We would like to extend the same protocol for other coins It will help to

• connect different coins to existent web 2.0
• quickly create a list of supported crypto currency for exchanges, multicurrency wallets and help new projects get the existing infrastructure instantly and effortlessly
• develop the cross-chain interface
