0x Extensions: Enabling New Types Ofexchange

We designed the 0x protocol to be extensible exchange infrastructure for the entire crypto economy. With the release of 0x v2.0 , we added the ability to not only support all tokenized assets but also completely new modes of exchange. The 0x Core Team has developed three extension contracts that enable projects to offer new forms of crypto trading to their users. We have deployed a Forwarder Contract , Dutch Auction Contract , and have templates for a Whitelist Contract . We plan on creating additional extension contracts to meet developers exchange needs. Our goal is to provide complete exchange infrastructure so that relayers can focus on building a business and optimizing their products UI/UX. The core component of the 0x protocol is the Exchange Contract. The Exchange Contract handles all validation paths and settlement. With a series of AssetProxies, the Exchange Contract facilitates token transfers for Ethereum standards like ERC-20 and ERC-721. Supporting new AssetProxies can be done without having to change 0xs current smart contract pipeline, and therefore do not force developers and users to upgrade. However, adding new AssetProxies come with varying levels of risk, as they modify the running state of the protocol. This state includes substantial token allowances and can directly interact with address balances. Due to the security-critical nature of these proxy contracts, we have enacted a 0x Improvement Proposal (ZEIP) process that gives the 0x community the opportunity to approve or deny changes to the protocol by voting with ZRX . For example, ZRX token holders recently voted on ZEIP-23 , which adds the ability to trade arbitrary bundles of ERC-20 and ERC-721 tokens via the MultiAssetProxy Contract. ZEIPs must be approved for AssetProxy contracts to be dep Continue reading >>

What Is 0x? (zrx) Beginner's Guide, Information & Review

Twitter Facebook WhatsApp Google+ Buffer LinkedIn 0x is an open protocol that is designed to offer a decentralized exchange as part of the Ethereum blockchain. 0x is made using a protocol that involves Ethereum smart contacts that allow those around the world to run a decentralized exchange. The team behind 0x strongly believes that in the future, you will find thousands of tokens from Ethereum and that 0x can provide an efficient and trustworthy way to exchange them. 0x is designed to be different from both centralized and decentralized exchanges, providing the best possible combination of features. The co-founders of 0x are Will Warren and Amir Bandeali , the first of which is the CEO and the second of which is the CTO. Both are in smart contract research and development. Warren used to conduct applied physics research at the Los Alamos National Laboratory after studying mechanical engineering at UC San Diego. Bandeali used to be a fixed income trader with DRW after he studied finance at the University of Illinois, Urbana-Champaign. Among the other team members, you will find blockchain engineers, software engineers, graphic and product designers, end-to-end business strategists, and people with other skills. The advisors for the project founded or work at companies such as Polychain Capital, Coinbase, and Pantera Capital. The 0x project is being funded by Fintech Blockchain Group, Pantera, Polychain Capital, Jen Advisors, and Blockchain Capital, showing a diverse range of interests. When Warren and Bandeali co-founded the 0x Project in October of 2016, they did so in hopes of a world that allows for every assets representation as part of the Ethereum blockchain. Ideally, the included assets would have everything from digital game items to stocks to gold and fiat cur Continue reading >>

Accounts - Should I Always Put 0x At The Start Of Ethereum Addresses? - Ethereum Stack Exchange

Should I always put 0x at the start of Ethereum addresses? Should I always put 0x at the start of Ethereum addresses?Sending ether to addresses without 0x seem to work perfectly fine. when sending to an address, do you include the "0x" before the rest of the number? The address in my coinbase starts with 0x, then the rest of the receiving address. However my wallet file i created with geth doesn't have the 0x in the name. This question feels a bit engineered, to improve its quality can you give some more context in the question itself in what context this question occurs? Joris Bontje Jan 24 '16 at 21:23 But is it a zero or letter O ? Chipper Fawkes Mar 3 at 19:56 @ChipperFawkes It's a zero. eth Mar 4 at 20:22 Yes but the 0x should already be there. You should not be typing addresses in manually because they currently do not have checksums and mistakes can be costly: more details here specifically be "careful to always include the "0x" on the front of the raw ones (which you should be doing anyways)". When transferring any large amounts, don't forget to test with a small amount first. Similarly, if you are copying+pasting and the 0x isn't already there (maybe some blockchain explorers don't have the 0x), be careful if you add the "0x". With Ethereum ICAP addresses, the 0x should not be added. Continue reading >>

What Is The 0x Project? The Most Comprehensive Guide Ever Written

What is The 0x Project? The Most Comprehensive Guide Ever Written 0x Project: The Future of Cryptocurrency Exchanges. C ryptocurrencies are all the rage right now and as FOMO spreads far and wide more and more people want to be a part of this economic revolution. However, this is where we hit a snag. In order to join this revolution, people need to go through centralized exchanges which have immense problems of their own. 0x Project: The Future of Cryptocurrency Exchanges This is why decentralized exchanges and the 0x Project in particular, are so important. In this guide, we will explore how the 0x Project works. However, before that, lets look at what exchanges, in general, are. The exchange serves one of the most critical functions in the crypto ecosystem. It basically acts as a portal between the Fiat world and the crypto world. There are usually two types of exchanges: Fiat to Crypto exchanges helps you buy Cryptocurrencies in exchange for Fiat money. Coinbase is a perfect example of this kind of exchange. Coinbase helps you buy BTC , BCH , LTC , and ETH in exchange for Fiat currency. Then we have the Crypto to Crypto exchanges. These exchanges help you exchange certain cryptos like BTC, ETH, BCH etc. for other cryptocurrencies. Binance is a fine example of a crypto-to-crypto exchange. While they do offer pretty valuable services, the problem is that they are all centralized , which makes them vulnerable. This is an extremely risky proposition when you consider the sheer amount of money that these exchanges deal with each and every single day. Lets look at the 24-hour volume of the top 5 exchanges in the world: Thats nearly 10 billion USD! And thats how much money they are processing every single day! Thats just absolutely ridiculous. Now, keeping in mind that cen Continue reading >>

Sendwyre On-chain Kyc Integration For 0x Based Exchanges In 4steps

Sendwyre On-chain Kyc Integration For 0x Based Exchanges In 4steps

SendWyre On-Chain KYC Integration for 0x based Exchanges in 4Steps KYC (Know Your Customer) is essential for mass adoption in the crypto space. With increasing SEC scrutiny and institutional involvement, the movers and shakers in global finance want to know with whom they are doing business. This is especially true of exchanges. Recently, Ive had the pleasure of helping Altcoin.io build their exchange on 0x. They are white-labelling their decentralized trading engine, so to win those important partnerships, KYC integration is a must. KYC is now a much easier process thanks to SendWyre combined with built-in filter contract functionality that is part of the 0x protocol . I am going to cover how to add your own whitelist of SendWyre KYC verified users to a 0x (ZRX) based exchange. There are a few nuances to integration which I am going to go over here. Note: This guide does not cover how to setup a 0x based relayer or the basics of Truffle setup. 0x released LaunchKit which makes it super simple to setup a 0x Relayer. This integration is based on the v2 specification of 0x protocol. When making a new order, point the senderAddress to a smart contract whitelist of SendWyre KYC verified users, and if both maker and taker are whitelisted, the trade is good to go. 0x provides an example whitelist contract in their mono repo . So how do you deploy this example? Since you dont need the rest of the repo, you can use a library called truffle-flattener. This compiles the whitelist and any of the sol file dependencies into a single compiled sol file to deploy. However, if you try to do this in the monorepo example, you will get errors. Instead, use the Altcoin.io repo to save you time finding all the dependency Solidity files yourself. Use flattener to compile the whitelist with a Continue reading >>

Hundreds Of Millions Of Dollars Locked At Ethereum 0x0 Address And Smart Contracts Addresseshow, Why And What Todo?

LinkedIn: www.linkedin.com/in/MuhammadAltabba, Github: www.github.com/Muhammad-Altabba Hundreds of Millions of Dollars Locked at Ethereum 0x0 Address and Smart Contracts Addresses How, Why and What todo? Some numbers about locked money at the time of this article: Tokens with a value of $164,817,747 is locked at 0x0 address . Ether with a value of $9,587,230.24 ($1,327.04/ETH) is locked at 0x0 address . EOS tokens with value of $1,040,773 are locked at EOS Token Smart Contract! Enigma tokens with value of $1,255,279 are locked at ENG Smart Contract! ZeroX tokens with value of $1,167,192 are locked at ZRX Smart Contract ! Augur (Rep) tokens with value of $63,343 are locked at REP Smart Contract ! Golem tokens with value of $317,200 are locked at GNT Smart Contract ! BAT tokens with value of $128,353 are locked at BAT Smart Contract ! Those are just some of the locked tokens. There more and more and more to count when we include other smart contracts and other addresses that people transfer to them by mistake. Before indulging, I would like to highlight the importance of solving the issue of Locked Money. Actually, it challenges the question: Is it a good idea to store and transfer digital money (Ether) and digital assets (Tokens) inside a programmable environment (Ethereum Platform)?. And in different words: Is Ethereum platform and its Smart Contracts, even those written by trusted parties, practically safe for all people to use to store and transfer money?. If the answer is No, then people might go for anther platform that does not have this issue (EOS, for example, will have a mechanism to overcome such situations). How can Locked Money happen, continuously? You can use your wallet, or write a code in solidity or Web3, and simply transfer Ether or tokens (many tokens Continue reading >>

Coinbase-backed Compound Launches, Users Can Short Ethereum (eth), 0x (zrx), Augur (rep)

Coinbase-Backed Compound Launches, Users Can Short Ethereum (ETH), 0x (ZRX), Augur (REP) Crypto Meet The Coinbase-Backed Compound Platform Per an official Medium blog post , Compound, an up and coming cryptocurrency platform and investment platform, has finally launched after multiple months in development. For those who are unaware, San Francisco-based Compound is a startup that intends to revolutionize how money moves in crypto by creating liquid cryptocurrency markets through algorithms, which will initially allow users to borrow and short-sell Ethereum-based tokens. As a result of the firms unique vision and sky-high ambitions, it quickly gathered over $8 million worth of financial support from juggernauts in this budding industry, including Coinbase , Andreessen Horowitzs a16z crypto fund, Polychain Capital and Bain Capital Ventures, which are all based in California interestingly enough. Compounds initial goal was to launch its platform in October, but as we can now see, the startup is a tad ahead of its schedule, launching on September 27, 2018, to the surprise of some investors. Now, users will be able to short sell four cryptocurrencies, which include Ethereum (ETH), 0x (ZRX), Basic Attention Token (BAT) and Augur (REP) via its easy-to-use, minimalistic website (seen below) that utilizes Web3 and MetaMask (or similar DApp browsers Coinbase Wallet) to complete functions and operations. Along with offering short selling, users who do not wish to bet against a crypto asset can lend any amount of the aforementioned tokens to earn interest, which is a great way for investors to gain a passive reward over time. Speaking with TechCrunch reporters, the startups CEO noted that if/when Compound scales, his will lead to some really interesting improvements in market stru Continue reading >>

Researchers Find Issues With 0x, An Ethereum-based Project Aiming To Raise Millions In An Ico

Researchers Find Issues With 0x, An Ethereum-based Project Aiming To Raise Millions In An Ico

Researchers Find Issues With 0x, An Ethereum-Based Project Aiming To Raise Millions In An ICO 0x (pronounced zero-x), an Ethereum-based project looking to raise $24 million in an initial coin offering (ICO) today, has some missing elements, according to agroupof computer scientists who recently examinedthe project under a microscope. The 0x ICO comes in the midst of a string of ICOs that have raised a total of $1.3 billion in funds this year for fledglingprojects built on blockchain platforms such as Ethereum, according to the news site CoinDesk. After reviewingthe project's publicly available Github code and white paper ,researchers atCornell Techs Initiative for Cryptocurrencies and Contracts (IC3),summarized their findings in a blog post on Sunday. According to their report, the 0x code is incomplete. 0x, however, claimed in an earlier blog post that it planned to distribute its tokens during the ICO using "fully functional" and "audited" smart contracts, a statement that couldhave led some to believe the protocol was at least nearly complete. Specifically, IC3 researchers say the 0x project does not fully specify how itplans to use its ZRXdigital tokenin a proposed governance scheme to upgrade the protocol, a missing linkthatbrings into question the potential for security risks. After this story went live, I wrote 0x for comment. In response, Will Warren, co-founder of 0x, sent an email explaining that 0x intentionally built a modular, upgradeable system so that a governance system could be "plugged in" at a later date. Referencing a previous Ethereum project where a code weakness resulted in a $50 million theft, he added that it does not pay to push out a complex system of smart contracts for governance too hastily. "The DAO clearly demonstrated the catastrophic d Continue reading >>

New Ethereum Dev Tools From0x

New Ethereum Dev Tools From0x

Today were releasing four new tools to help Ethereum developers working on smart contracts. Were excited to finally release these tools publicly, as we have been using them for a while internally at 0x and have shared them with a few other projects in the community. Check out sol-compiler , sol-trace , sol-coverage , and sol-profiler to get started! At 0x, we embrace the UNIX tools philosophy: each tool should only do one thing, and one thing well. When we started building 0x protocol, Truffle was the de-facto framework for projects. It worked reasonably well and were glad that it helped us get started. However, as we grew, our requirements evolved and we kept pushing the boundaries of what was possible with the framework. Truffle is the Ruby-on-rails of Solidity development and we found it hard to extend it in unintended ways. Thats why we decided to build a set of modular tools that can be combined together and used by others. None of the tools we are releasing today are 0x-specific. You can start using them in your project independently of your current stack (even with Truffle projects!). By evaluating the existing toolset and breaking up our workflow into logical pieces, weve realized that Ethereum development consists of two main stages. Compiling contracts into artifacts and then doing stuff with those artifacts (e.g running tests, debugging, verifying or analyzing metrics, etc). Unfortunately, there is no single artifact format used by all tools. Some that have reasonable adoption are Truffles artifacts and Soliditys standard JSON output (SSJO from now on). Truffle artifacts include a lot of compiler metadata that we never used and were missing other pertinent pieces of data. Unfortunately, there is no way to customize what compiler metadata is included by Truff Continue reading >>

0x is an open protocol that facilitates peer-to-peer exchange of digital assets on the Ethereum blockchain. 0x is open source, free to use, and provides a drop-in exchange solution for developers to build on top of. Developers use 0x protocol to build decentralized exchanges (DEXs), marketplaces for digital collectibles, and to integrate exchange functionality into wallets. - Description from ethhub.io This article originally appeared in the 0x developer portal A relayer is any party or entity which hosts an off-chain orderbook. They provide a way for users to add, remove and update this orderbook through an API, GUI or both. In doing so, relayers help traders discover counter-parties and ferry cryptographically signed orders between them. Once two parties agree on the terms of an order, the order is settled directly on the Ethereum blockchain via the 0x protocol smart contracts. There are many advantages to a decentralized exchange over centralized exchange. One of the largest problems with centralized Exchanges is that they must hold and secure the funds of all the traders on their platform. This causes there to be a single point of failure that if hacked or mismanaged, means that all these traders could lose their funds. Hundreds of millions have already been stolen in this way. With a decentralized exchange, traders do not need to deposit funds with a centralized entity, but instead can trade directly from their individual wallets (including hardware wallets!). This means the user is in control of their funds at all times, eliminating this single point of failure from the equation. In 0x protocol, orders are transported off-chain over any arbitrary medium, massively reducing gas costs and reducing blockchain bloat. Relayers help broadcast orders and can choose to c Continue reading >>

5 Reasons To Keep An Eye On 0x Protocol

5 Reasons To Keep An Eye On 0x Protocol

Centralized exchanges have 3 basic problems: hacks, downtime, and fees. The issue of hacks is well-known in the blockchain world. We have seen massive hacks like that of Mt. Gox, Bitfinex, and, very recently, Coincheck. These constitute a growing concern for users. Many do not want to take on the risks associated with centralized exchanges. In fact, many of the top names in the crypto ecosystem have echoed time and time again: do not leave your funds on an exchange. You do not have the private keys to the wallet account on an exchange, hence your funds could potentially be accessed by hackers. On the 0x protocol, there is no fear of this. This is because, until you exchange them with another currency, your funds stay in your wallet to which you own the private keys. This makes 0x more secure for users. The downtime suffered by centralized exchanges do not apply to the 0x protocol. Exchanges like Coinbase, Poloniex, and GDAX have suffered significant downtime that has affected traders. On-chain decentralized exchanges also grind to a halt or charge high fees when the Ethereum network is congested. The 0x protocol, however, is off the blockchain until the order is set to be filled. Congestion on the Ethereum network will not stop orders from being made, it will only affect the rate at which transaction happens. And finally, as stated above, the 0x protocol does not charge a fee. The relayers can charge a fee (in ZRX) for their service, and the user also pays gas for the transaction on the Ethereum blockchain when the transaction is executed. These make 0x a better option to centralized exchanges. 4. Possibility of Integration to Other Chains in the Future At the moment, the 0x protocol is restricted only to ERC-20 tokens. However, based on the current state of the Ethere Continue reading >>

0x Teams With Starkware To Bring Speed To Decentralized Exchanges

0x Teams With Starkware To Bring Speed To Decentralized Exchanges

0x Teams With StarkWare to Bring Speed to Decentralized Exchanges A cryptographic solution called zero-knowledge proofs (ZKP) could help notoriously slow decentralized exchanges (DEXs) reach speeds comparable to more traditional platforms. San Francisco-based DEX startup 0x is partnering with the Israeli software-as-service company StarkWare to test a ZKP solution called StarkDEX, which can process roughly 500 transactions per second. StarkWare CEO Uri Kolodny told CoinDesk the goal is clear: Non-custodial trading at scale. Speaking to how ZKPs could be implemented in the 0x DEX ecosystem, 0x marketing lead Matt Taylor told CoinDesk: Our goal is that by the end of this year well have this in production, on mainnet, so that people can actually use this technology. We intend to have this be a core part of the 0x DEX stack. Taylor said the 0x system has facilitated 713,000 trades for a volume of about $1 billion since it was founded in 2017. DEXs using 0x currently process between a few hundred and roughly 3,100 trades a day, according to 0xtracker.com , but scaling continues to be a challenge. A marketplace where only three trades per second can be settled is a very illiquid market, Kolodny said of some networks current limitations. Still, Kolodny told CoinDesk it will take months before this alpha test leads to a professional service for 0x relayers and other blockchain companies. Stepping back, StarkWare attracted investment from ConsenSys Ventures, ethereum creator Vitalik Buterin and the Zcash company, to name a few. This startups ZKP expertise and solutions are so sought after that the Technion University , where StarkWare co-founder Eli Ben-Sasson also works as a professor, filed a lawsuit claiming Ben-Sasson is getting rich from the universitys intellectual proper Continue reading >>

Where & How To Buy Zrx(0x)

Where & How To Buy Zrx(0x)

I think its important to understand at least the very basics of what youre purchasing, so this and all future articles will include a short introduction to get you started. ZRX(0x) is an open protocol that is designed to offer a decentralized exchange as part of the Ethereum blockchain. At its core, 0x is a system of smart contracts that can be used by anyone it is open-source and completely free to use. To begin with, we need to buy either Bitcoin or Ethereum to buy any Cryptocurrency on exchanges. So follow the link below to buy Ethereum on Coinbase and then follow the next steps to buy ZRX on Binance . If you already have Ethereum with you you can skip this step and go on to Binance registration. Binance is a cryptocurrency exchange with relatively less transaction fees and been faring good so far without any issues and good support response. There are two options for trading platforms on Binance : Basic and Advanced. Ill be primarily covering the Basic trading option in this article, but you can check out the Advanced view below. There are not many differences between the two views with the exception of being able to do more detailed technical analysis in the Advanced view. Once youve registered on Binance and logged in, you can see few menu items on top right corner. One of the is Funds which has a sub menu item named Deposits Withdrawals. This is the place where you can see all your coins(purchased on Binance and received from other addresses). So in order to send Ethereum which we bought on Coinbase or Gemini to Binance , we need to have an Ethereum address we can find this on this page. Check out the following screenshots to learn how to deposit Ethereum to Binance from Coinbase Copy the address and send your ether from Coinbase / Gemini to this address. Once y Continue reading >>

What Is 0x? 2019 Beginner's Guide On Zrx Cryptocurrency

Future of ZRX Cryptocurrency and know how to buy ZRX 0x is an open protocol that facilitates low friction peer-to-peer exchange on the Ethereum blockchain, founded byWill Warren(CEO) andAmir Bandeali (CTO), According to the official website, 0x is the prefix for hexadecimal numeric constants including Ethereum addresses. In a more abstract context, as the first open protocol for exchange 0x represents the beginning of the end for the exchange industrys rent-seeking oligopoly: zero exchange. 0x is not an application like other coins. It is a protocol, essentially a set of smart contracts, founded by a team with a rich experience in Smart Contract research and blockchain engineering, led by CEO Will Warren. The difference between a protocol and application is a protocol a standard path to transfer data or information. 0z is primarily focused on transferring tokens issued on the Ethereum blockchain from one person to another, without racking up high fees or time delays. 0x facilitates trustless low friction exchange of Ethereum based assets. Ethereumis the popular open-source, public, blockchain-based distributed computing platform. Basically, 0x is trying to make it simpler to go from one token to the next on the blockchain. It does this by making transactions from one token to another much faster. Exchanges involve high costs, which 0x is trying to break down. But decentralised exchanges (the ones that run with smart contracts) have their own issues - gas fees can still add up quickly, and transactions can get slow. 0x intends to fix this by moving most of its transactions offchain, or outside the blockchain. 0x uses relayers, which are smart contracts that broadcast the orders they have to the 0x blockchain, functioning like mini exchanges of sorts. A trade is executed Continue reading >>
