CryptoStars on Binance Feed: Decentralized Exchange Development A Glimpse

Every DEX crypto is intended to bring the benefits of decentralization to crypto buying, selling, and portfolio management. On the other hand, even though smart contracts are rules-based, the lack of an intermediary third party means that the user is left to their own, so DEXs are meant for sophisticated investors. CEXs operate using an order book system, which means that buy and sell orders are listed and sorted by the intended buy or sell price. The matching engine of the exchange then matches buyers and sellers based on the best executable price given the desired lot size. Hence, a digital asset’s price will depend on the supply and demand of that asset versus another, whether it be fiat currency or cryptocurrency.

These exchanges are decentralized, so there is no need for a middleman or other third party to authorize and authenticate transactions. For instance, in the case of the bitcoin network, network users individually approve transactions before transmitting authentication information to all network nodes. Investors are incentivized to contribute assets into the pool to provide liquidity and are thus referred to as liquidity providers . As a reward for their participation, they get a share of the fees traders pay to access or ‘draw’ from the pool.

What Are the Benefits of Decentralized Exchanges?

Other than the above features, DEXs also have inherent advantages such as reduced fees, simple interfaces, and quick transaction processing times. By cutting out the intermediaries present within the CEX model, it is possible to realize most of these benefits. At their heart, KYC regulations are meant to prevent cases of money laundering, identity theft, and other financial crimes. In 2021, cryptocurrency exchange Coinbase went public and achieved a market capitalization of more than $86 billion. This system can be achieved by creating proxy tokens or assets or through a decentralized multi-signature escrow system, among other solutions that are currently being developed. By removing the need for a trusted third party to hold user funds or execute trades, DEXs reduce counterparty risk.

This also significantly reduces the risk of data breaches and protects users’ privacy. Programming code that enables applications to self-execute agreements, otherwise known as a smart contract, automatically ensures the BTC trader obtains ETH and the ETH trader obtains BTC. Moreover, some wallets like TrustWallet are DEXs themselves with the function built-in, so one can simply perform the swaps directly inside the wallet instead of connecting to a platform. Centralised exchanges, as the authority validating transactions on their platform, can support various native cryptocurrencies, making it easy to trade cross currencies. Thanks to market makers, and fast execution of trades, centralised exchanges have more liquid markets and offer institutions an attractive setting for their trades.

Decentralized vs. Centralized

Recording transactions directly on the blockchain and not on the exchange platform is a cornerstone of decentralized exchanges. Centralized exchanges are much more susceptible to hacks and data breaches than decentralized exchanges. To infiltrate the system, a hacker need only bypass the defenses of the company running the exchange to access users’ holdings, financial information, and other potentially damaging data. Centralised and decentralised exchanges both exist to enable users to trade digital assets. They do so in very different ways, one by handling and verifying all transactions through centralised servers, while the other running as a permissionless smart contract.

  • The company in charge is responsible for holding a ledger, executing transactions, securing user data, and the other responsibilities that come with managing a financial system.
  • It’s essential for users to be aware of potential risks and concerns when using DEXs and to thoroughly research their options before selecting a platform.
  • The processes for using decentralised exchanges can be less intuitive than those people are used to from TradFi.
  • It is both resource-intensive and time-consuming, due to requiring extensive backend development.
  • DEX aggregators connect to various DEXs liquidity pools to offer a fluid trading experience at low costs and minimal slippage.

These exchanges are considered centralized because one company oversees all the transactions and sets the exchange’s rules and fees. For example, Coinbase and create and run popular CEXes for a profit. The companies offer browser-based platforms and mobile apps, and they can make money when you use their exchanges to buy or sell cryptos. You can think of liquidity pools as the massive cash reserves which banks use for offering financial services to their customers. The liquidity pools can give crypto traders adequate crypto assets for purchasing, selling, or borrowing. Therefore, they don’t have to wait for another party to match their transaction request for completing the transaction.

Public blockchains have the potential to act as a potent equalizing force for the world by equal access to financial services in the same way that the internet has democratized access to information. Decentralized exchange technology will play a key role in accelerating our transition to a financial system where people can transact directly, on a peer-to-peer basis, with no middlemen required. In compliance with Anti Money Laundering and other global/local regulations, most centralized exchanges have KYC-based onboarding procedures.

Some 99% of crypto transactions are facilitated by centralized exchanges, which suggests that they are accountable for the majority of the trading volume. Due to the lack of volume, decentralized exchanges often lack liquidity, and it can be difficult to find buyers and sellers when trading volumes are low. Due to their nature of allowing for the peer-to-peer exchange of cryptocurrencies, decentralized exchanges prevent market manipulation, protecting users from fake trading and wash trading.

How does a DEX platform make money?

This is where you’ll finally learn how to implement the above-outlined snippets of code. Centralized exchanges offer beginner investors a familiar, friendly way of trading and investing in cryptocurrencies. Centralized cryptocurrency exchanges act as an intermediary between a buyer and a seller and make money through commissions and transaction fees. You can imagine a CEX to be similar to a stock exchange but for digital assets. A decentralized exchange enables users to trade crypto assets through blockchain transactions without the need for a custodian or centralized intermediary.

Moreover, with this model, users provide liquidity to a pool of crypto and assets are priced by specialized algorithms. An automated market maker is a digital tool or protocol used to facilitate trustless crypto transactions, that is, without a third-party. One of the most apparent benefits of a decentralized exchange is cutting out the middlemen and executing peer-to-peer transactions without central authorities. They are pieces of code written on top of blockchain networks like Ethereum that trigger various outputs when given certain inputs. DEXes often support a wide variety of cryptos, including brand-new offerings you might not find on a CEX. However, many DEXes don’t support dollar-to-crypto trades, meaning you need to add funds to your crypto wallet before using a DEX.

You might also see them described as self-executing smart contracts, referring to pieces of code written on top of blockchains like Ethereum and that are triggered when predetermined conditions are met. When using a decentralized cryptocurrency exchange, users need to connect their Web3 wallets, such as MetaMask. Once connected, users can exchange their assets, invest in liquidity pools, and perform other DeFi actions. The actual options vary; however, the simplest options are DEXs with token swaps, just like the one you had a chance to build in the above tutorial. One of the main benefits of DEXs is the high degree of determinism achieved by using blockchain technology and immutable smart contracts. Whereas in centralized exchanges , such as Coinbase or Binance, the platform facilitates trading using the internal matching engine of the exchange, DEXs execute trades through smart contracts and on-chain transactions.

One of the other benefits of certain CEXs is the option to leverage your investments using borrowed money from the exchange, called margin trading. It allows investors to reap higher returns, but losses can also be amplified. An order book—a real-time collection of open buy and sell orders in a market—is a foundational pillar of electronic exchanges. Order books allow an exchange’s internal systems to match buy and sell orders. The vision behind many DEXs is to have permissionlessly accessible, end-to-end on-chain infrastructure with no central points of failure and decentralized ownership across a community of distributed stakeholders.

Build a Decentralized Cryptocurrency Exchange

Before a user can trade on a CEX, they must sign up and verify their account. If they own crypto, they can deposit to an exchange wallet which credits their account, ready for trading. If not, prospective traders can use fiat on-ramps to purchase crypto with credit cards, bank transfers, and more.

How does a DEX work?

They maintain their liquidity by keeping the funds of their users on the platform, which makes them susceptible to large-scale theft. It also allows them to conduct an “exit scam,” where they claim an event has caused them to lose control of the private keys and the connected funds. Thanks to the crazy returns of investment on altcoins during the 2017 bull run and the 2020 DeFi boom, more and more users have been drawn to cryptocurrency trading in recent years. As a result, we’ve seen the development of innovative exchange platforms that are marketed as complete solutions to everyone’s crypto trading needs. Centralized exchanges offer an extra layer of security and reliability when it comes to transactions and trading.

That said, with continual innovations bringing the blockchain ecosystem forward, DEXs are expected to play a central role and offer greater scalability, security, transparency and use cases. However, given the wide variety of coins featured on a DEX, including so-called ‘shit coins’, it can lead to extreme volatility conditions. As we’ve discussed earlier, DEX participants are rewarded for providing liquidity to an exchange, enabling passive income opportunities for all users. In crypto, users are also looking for the best trading rates across a wide number of sources and DEX aggregators act as a search engine. This way, users can access cheaper, quicker and more efficient financial tools.

However, just like we need browsers to access the internet, we need some gateway to access blockchain ecosystems. This role is currently played by cryptocurrency exchanges and some specific crypto wallets with exchange features. Decentralized exchanges don’t have a single point of failure, neither in terms of asset storage nor in terms of the overall network. While funds remain in the user’s secured wallet, the network is secured using the underlying blockchain’s protocol and also by the virtue of being decentralized. Blockchains are known for being highly secure platforms for engaging in financial transactions. However, the truth is that a crypto exchange will only be as secure and reliable as the smart contracts it uses since there isn’t a central authority overseeing its functioning.

The two most common types are order book DEXs and automated market makers . DEX aggregators, which parse through multiple DEXs on-chain to find the best price or lowest gas cost for the user’s desired transaction, are also a widely used category. In addition, as user funds don’t pass through a third party’s cryptocurrency wallet during trading, DEXs reduce counterparty risk and can decrease systemic centralization risks in the cryptocurrency ecosystem.
