Why Decentralized Exchanges Are Important in the Crypto Economy

Jackson Wood is simply a fiscal advisor astatine Freedom Day Solutions.

Back successful 2012, arsenic an excited economics undergrad, I decided I wanted to put immoderate of the wealth I had into bitcoin (BTC). It was a analyzable process that progressive driving to Walmart (WMT) and sending a MoneyGram wealth bid to a institution called ZipZap, which would past nonstop my wealth to a institution called BitInstant. After a fewer weeks, BitInstant would deposit my bitcoin into my wallet connected the Japanese bitcoin speech Mt. Gox. The full process took implicit 3 weeks, and I ever wondered however this innovative integer currency would ever regenerate its contention if this was the process.

Shortly aft my archetypal bitcoin experience, centralized companies specified arsenic Coinbase (COIN), QuadrigaCX and Bitstamp appeared connected the scene. These companies had slope accounts, which meant they were fundamentally plugged into the modern fiscal strategy and made it importantly easier to acquisition cryptocurrencies.

These centralized crypto exchanges seemed to enactment perfectly – until they didn’t. Mt. Gox was attacked successful 2014 and implicit 850,000 bitcoins were stolen. Bitstamp was hacked successful 2015, BTC-e was unopen down successful 2017 and the infamous QuadrigaCX was hacked – by its proprietor and CEO – successful 2018 and yet unopen down, having mislaid each its clients’ coins, successful 2019.

Not each centralized exchanges person had issues. There are galore presently operating that person had years of palmy concern operations and galore blessed customers. Centralized exchanges person their ain negatives, however. They’re forced to obey know-your-consumer (KYC) regulations of the state successful which they reside, they person limits successful presumption of bid publication size and they necessitate the idiosyncratic to spot the solvency of the business, thing often seen arsenic a antagonistic by autochthonal crypto users.

A operation of these issues, on with the development of astute contracts, yet led to an elegant solution: an speech level built wholly connected crypto, successful a wholly trustless and decentralized mode – a decentralized exchange. For the 2nd portion of this bid connected decentralized finance (DeFi), we’ll research wherefore decentralized exchanges, oregon DEXs, are truthful important successful the crypto economy.

DEXs are precise analyzable astute contracts but they person elemental goals: to supply liquidity to anyone who wishes to commercialized cryptocurrencies. The astir fashionable DEX is Uniswap, which is built wholly connected the Ethereum blockchain. Uniswap provides a decentralized trading platform for immoderate crypto idiosyncratic who wishes to commercialized Ethereum-based tokens.

DEXs person a fewer important benefits implicit centralized exchanges. They bash not necessitate KYC and they run 24/7. They besides supply investors with output farming opportunities, which are opportunities to assistance facilitate decentralized swapping – oregon trading – of integer assets successful speech for a tiny fee. And the astute declaration codification (Uniswap is written successful Solidity) is unfastened and transparent, allowing crypto natives to simply verify the codification alternatively of trusting a centralized concern to beryllium solvent.

DEXs do, however, person immoderate drawbacks. Transactions are irrevocable, they lone let you to commercialized a azygous chain’s plus – Uniswap is lone connected Ethereum, for illustration – and there’s rug propulsion hazard and impermanent hazard (topics we’ll sermon successful greater item successful the adjacent nonfiction successful this series).

Unlike centralized exchanges (in some crypto and accepted finance, oregon TradFi) that usage bid books, a strategy that has worked good for implicit 2 centuries, DEXs usage 2 innovations to supply services to their users: liquidity pools and automated marketplace shaper services.

Essentially, DEXs supply liquidity – pools of paired assets – that traders tin usage to swap 1 token for another. Liquidity pools are astute contracts that traders utilize to determination successful and retired of definite tokens based upon their goals. Automated marketplace shaper services are analyzable astute contracts wrong the liquidity excavation astute contracts that power the terms of definite crypto trading pairs successful liquidity pools and summation oregon alteration terms based connected proviso and request successful the market.

The astute declaration that governs liquidity pools relies connected a circumstantial look for determining the terms of each token. The look is X * Y = k. X and Y are represented by tokens, and k represents the constant. This look fundamentally governs the liquidity pool. (We’ll bash a heavy dive into liquidity pools and automated marketplace shaper systems successful my adjacent article.)

Not lone bash liquidity pools connection traders entree to decentralized liquidity, they besides connection concern opportunities to those wishing to involvement assets successful the liquidity pool. When a idiosyncratic swaps assets done a liquidity pool, a precise tiny interest is paid to the individuals who are providing the liquidity. To enactment this successful communal TradFi terms, those who lend superior to the liquidity pools fundamentally gain a interest akin to that of a marketplace maker. Liquidity pools, particularly caller ones, connection precise precocious yields to investors. This conception is called output farming, and provides income opportunities for those who recognize the concept.

In Q4 2021, for instance, Uniswap processed $238.4 cardinal worthy of trades, an summation of 61% from Q3. A full of $681.1 cardinal was traded done Uniswap liquidity pools successful 2021.

The main takeaway is that DEXs supply each the aforesaid services arsenic centralized exchanges, yet they bash it successful an anonymous and trustless manner. Technology present allows for this to beryllium extracurricular of immoderate regulated manufacture and increases entree to these fiscal services for everyone.

Prior to the instauration of Ethereum, traders were forced to usage a centralized strategy to speech and commercialized immoderate asset. Smart contracts person opened the doors to a trustless and wholly unfastened fiscal strategy that, if utilized correctly, has the accidental to bring economical benefits to each participants.
