Exploring Decentralized Exchanges (DEX): Advantages and Challenges

[cyrilmorris]

Hello, fellow crypto enthusiasts!

I wanted to start a discussion about decentralized exchanges (DEX) and explore their advantages and challenges. Decentralized exchanges have gained traction in crypto due to their unique characteristics and potential benefits.

Let's dive in and explore the key aspects of DEXs:

Advantages of Decentralized Exchanges (DEX):

Enhanced Security and Control: DEXs prioritize the security and control of your funds. Unlike centralized exchanges where you have to deposit your assets, DEXs allow you to retain control of your private keys, reducing the risk of hacks or theft.

Privacy and Anonymity: DEXs offer increased privacy as they don't require users to disclose personal information or go through identity verification processes. This feature attracts users who prioritize anonymity in their crypto transactions.

Resilience and Transparency: DEXs operate on decentralized networks, which means they don't have a single point of failure. This decentralized nature enhances the resilience and transparency of the trading process, reducing the reliance on intermediaries.

Access to a Diverse Range of Tokens: DEXs often support a wide range of tokens, including those not listed on centralized exchanges. This opens up opportunities for users to explore and invest in a diverse set of projects and assets.

Global Accessibility: DEXs provide access to global markets without restrictions or geographical boundaries. Anyone with an internet connection can participate in trading, empowering users from various regions to engage in the crypto economy.

Challenges of Decentralized Exchanges (DEX):

Liquidity: One of the primary challenges for DEXs is liquidity. As trading volumes are fragmented across different platforms, achieving the same liquidity levels as centralized exchanges can be difficult. However, innovative solutions like liquidity pools and automated market makers (AMMs) are addressing this challenge.

User Experience: Some DEX platforms may have a steeper learning curve and less intuitive interfaces compared to centralized exchanges. However, user feedback and ongoing development efforts are improving the user experience and making DEXs more user-friendly.

Smart Contract Risks: DEXs rely on smart contracts for executing trades, and vulnerabilities in smart contracts can be exploited by attackers. DEX platforms must conduct rigorous audits and implement robust security measures to mitigate these risks.

Transaction Speed and Scalability: Depending on the underlying blockchain network, DEX transactions may face scalability limitations and slower execution times compared to centralized exchanges. However, advancements in layer 2 solutions and blockchain technologies are addressing these issues.

What are your thoughts on decentralized exchanges?

Have you had any experiences with DEX platforms? What advantages and challenges have you come across? Feel free to share your insights, opinions, or any interesting stories related to DEXs. Let's engage in a constructive discussion and learn from each other's experiences in the exciting world of decentralized exchanges!

What you are referring to are those smart contract exchanges which some people are called decentralized exchanges. The decentralized exchanges known for me are those like Bisq.

On smart contract exchanges, they are specific to a particular blockchain. Example is Ethereum blockchain which you can only trade ether and ERC20 tokens. Another example is BSC and Binance Beacon Chain which you can only trade BNB, BEP2 and BEP20 tokens only. Is that not centralized? You can not trade other coins and tokens that are not existing on the specific blockchain, which makes them not to be decentralized.

Enhanced Security and Control: DEXs prioritize the security and control of your funds. Unlike centralized exchanges where you have to deposit your assets, DEXs allow you to retain control of your private keys, reducing the risk of hacks or theft.

It only enhance control, not security.

Also know that the smart contract exchanges are more susceptible to hack even than centralized exchanges. Smart contract exchanges are often hacked than centralized exchanges. But centralized exchanges is also not good because they are not your keys on the exchanges.

If you're a crypto dude (outside of bitcoin-only), then these 'DEXs' are a godsend. The fact that you don't need to deposit your funds to a centralized exchange/custodian to be able to trade/swap assets is simply excellent.

Obviously the liquidity isn't as good as the likes of Binance, but I'll take it.

I'm not a big fan of altcoins, I've only had a few experiences with this after getting the token airdrop, luckily it's BSC20 based which doesn't charge a lot of swap fee.

But to interact with this kind of DEX it is necessary to grant access permission to the wallet, a certain level of permission allows the DEX to do anything including emptying the balances. I will still take it very carefully to trade large amounts.

Yes — unless you can read smart contract code, you can't really know for sure if a 'DEX' has malicious code or not. Fortunately this is easily circumvented by simply using a different wallet for your cold storage, and a different wallet for your swaps(or smart contract usage in general).

Smart Contract Risks: DEXs rely on smart contracts for executing trades, and vulnerabilities in smart contracts can be exploited by attackers. DEX platforms must conduct rigorous audits and implement robust security measures to mitigate these risks.

I think you are talking about bridges here, as bridges use smart contracts to exchange between cryptocurrencies on different blockchains, which is different from decentralized platforms.

Liquidity: One of the primary challenges for DEXs is liquidity. As trading volumes are fragmented across different platforms, achieving the same liquidity levels as centralized exchanges can be difficult. However, innovative solutions like liquidity pools and automated market makers (AMMs) are addressing this challenge

I do not like solutions to provide liquidity such as pools or automated market makers (AMMs) because they are all based on making a profit from user deposits.The best is to give them profits such as transaction fees and focus on promoting to attract many new users.

All the advantages that you mentioned require that decentralized be real it has to be open source and you need to manage it yourself and not a central site that claims to be a decentralized platform just because it does not require users to KYC.

Enhanced Security and Control

Privacy and Anonymity

Access to a Diverse Range of Tokens

Global Accessibility

You've mentioned there's a smart contract risk, it ruin the security because there's no complete secure. If you have a key you can control your token, but altcoins are centralized and the owner can control all of his coins including in non custodial wallet.

There's no privacy and anonymity if you not able not use via Tor and there's a mixer can mix the token.

Those swap platforms let everyone add their own token and there's a chance to buy a fake token.

There's no global accessibility since the site has their own rules.

You further represent that you are not (a) the subject of economic or trade sanctions administered or enforced by any governmental authority or otherwise designated on any list of prohibited or restricted parties (including but not limited to the list maintained by the Office of Foreign Assets Control of the U.S. Department of the Treasury) or (b) a citizen, resident, or organized in a jurisdiction or territory that is the subject of comprehensive country-wide, territory-wide, or regional economic sanctions by the United States. Finally, you represent that your access and use of any of our Products will fully comply with all applicable laws and regulations, and that you will not access or use any of our Products to conduct, promote, or otherwise facilitate any illegal activity.

The only one decentralized exchange is Bisq.

Another example is BSC and Binance Beacon Chain which you can only trade BNB, BEP2 and BEP20 tokens only. Is that not centralized? You can not trade other coins and tokens that are not existing on the specific blockchain, which makes them not to be decentralized.

Decentralized means that there is no custodial party involved - In the case of decentralized exchanges, it means that no third party holds your coins at any point in time during the trade/Your orders are matched with other people without a third party being an intermediary for the trade.

Bridge services allow you to move your assets across chains. Some bridges also enable Bitcoin. So being a part of a chain like Ethereum and using DEXes there does not mean that it's technically centralized just because you can only trade ETH and ERC20s. I do agree that Binance Smart Chain is somewhat centralized because of its essential ownership and extensive tracking by Binance, though I would not agree that DEXes on Ethereum is not decentralized.

Decentralized exchanges lack the simplicity that centralized ones have. And people generally opt in for that which is easier to use. If you compare a popular CEX to a popular DEX, the trading environment is completely different. One requires a button press and coin A gets exchanged to coin B. The other requires being online to make the trade and find a matching offer yourself. Then the other party also has to agree. The whole process takes longer.

DEXs have many advantages but they need to be dumbed down for the average Joe to learn how to use them without spending time reading FAQs and different documentation.

I cannot lump smart contract risks cause there are different exchanges out there, but this presents little threat compared to the risk of your coins being hacked and stolen off a centralized exchange hot wallet or being stolen by the exchange themselves.

Transaction speed is dependent on the network and not the exchange. If anything decentralized exchanges gives you the liberty to determine thee you pay since you are making the trade from your personal wallet while with a CEX you will likely overpay for every transaction and cannot control it through RBF.

Uniswap or those DEX that's orderbook type are good as long as they don't need KYC, I think this KYC is among he criteria in considering a exchange a DEX. Same problem til today with liquidity on them and even the tokens that you wish to invest are not in these DEXes.

There are wallets today that you can swap or trade already I think Electrum, Mycelium or even the Trust wallet already has this feature which you can consider it a DEX inside a wallet.

You started this thread on 12/6 and then you wrote the same topic one day later 13/6 in the exchanges section but you only changed the title With some modifications (but same ideas):
Centralized vs. Decentralized Exchanges: Which is Right for You?
https://bitcointalk.org/index.php?topic=5456185

This is against the forum rules, If you feel this is not the right section for the topic you should have moved the thread there instead of writing a new one.

Some newbies or thinks engaging in doing things like this will fast track their learning and ranking up on the forum as a means of getting more merits, just as you've said, i don't also see anything different in the two, another mistake some do is that they have that mindset of till they created a topic before they can earn merits, just a single reply that will be on point will also generate you some merits.

What are your thoughts on decentralized exchanges?

I have never faced any transaction speed limitation in DEXs. But you still mentioned that factor in the limitation list so i thought, you might have faced any. One limitation i found in DEXs such as decentralized swaps, like, sushi swaps and Pancake swaps that they do not provide better graphs to analyze the token past movement which i prefer them to include. Plus, there are many fake decentralized exchanges in the market that can scam you so i only prefer to use those which are old enough to be trusted. One limitation is that if we made a trade like future trade and by any chance, if your liquidation price of BTC is 25000$ and they liquidate you on 25001$ and you have proof of that whom to contact for that because that's what decentralization means If you lost something it's your problem exchange is not going to help you.

But i had an experience back in like 2020 or 2021 when i was involved in future trading on Binance (CEX) with my friend and when i made a profit or loss i always share it with him and he does the same by taking a screenshots and one day he liquidated on the wrong price but when he contacted on the support they returned his money which i was not expecting them to return if they were decentralized exchange.

People with traditional mindsets always prefer exchange which is old and there is some entity behind it whom you could contact or at least blame when anything happens.

Are there any dex'es that allow trading bitcoin or altcoins against a stablecoin with leverage or derivatives?

What are the latency and spread?
