A cryptocurrency exchange is a platform that allows people to trade cryptocurrencies for additional assets, such fiat or digital currencies. Different crypto exchanges might offer different features and options.
New users must register before they can trade on a centralized cryptocurrency exchange. There are different levels of verification. In some cases, just confirming your email address is enough. Others require you to upload a passport photo. This KYC (Know Your Customer) process is necessary to ensure that crypto-related businesses comply with anti-money laundering measures.
Although cryptocurrency exchanges can be compared to stock exchanges in many ways, the main difference is the way that traders make profits. Stock exchange traders trade assets to make money from changes in rates. Cryptocurrency exchange traders sell and buy assets, but they can also profit from volatile currency rates. Although stock exchanges may have fixed hours of operation, crypto exchanges are open 24 hours a day, seven days a week, and 365 days a calendar year.
To start cryptocurrency trading on an exchange, you will first need to fund your wallet. This means you will need to add fiat currency such as USD or EUR to your account through a bank transfer or using your credit or debit card. The exchange acts as a custodian. It issues IOUs to users for them to trade on the platform.
To trade crypto on an exchange, users can set orders. As with the stock exchange, the centralized or traditional cryptocurrency exchange platforms offer market orders, limit orders, and stop-limit orders.
Decentralized Exchanges (DEXs)
DEXs are decentralized applications (DApps) that allow users to trade directly between themselves without the need for a central intermediary such as Binance or Coinbase. They can provide access to more cryptocurrency tokens and financial services that you won’t find on centralized exchanges. Some unique options offered by DEXs include flash lending, yield farming, and token staking.
This infrastructure of a DEX is entirely different from centralized exchanges, where users hand over crypto assets to the exchange.
Initial conceptions of DEXs were to eliminate the need to have any central authority to approve or supervise trades within an exchange. DEXs can use smart contracts to operate automated order books or automated market makers and trades. They are truly peer-to-peer and follow the principle of a decentralized network, which stands at the core of cryptocurrency and blockchain technology.
Some early DEXs used the order book system, which means that a network node was keeping track of the orders. Then automated market maker (AMM) DEXs were introduced, which are now the most popular type of decentralized exchange. They use smart contracts to create liquidity pools which are then used to exchange the tokens. Some of the most popular AMM DEXs are sushiswap exchange, Uniswap, PancakeSwap, and more are launched every year.
What is Sushiswap Exchange?
sushiswap exchange is a decentralized exchange that uses the AMM protocol, and it is based on the Ethereum blockchain. Created in the summer of 2020, it is a forked version of Uniswap. While some core features are the same, it also offered new financial services. For instance, it does not have an order book, instead of using smart contracts to facilitate the selling and buying of crypto. An algorithm determines the price.
Initial plans for the project were made by an individual who went by the pseudonym Chef Nomi. Soon, another pseudonymous core contributor, 0xMaki, was added to the team.
The initial liquidity of the platform was obtained from Uniswap by using a novel, creative, and ethically questionable method called a vamp attack. This strategy is used to bootstrap automated market makers and source liquidity. The initial liquidity is not drawn organically but is instead sourced from another platform.
sushiswap exchange strongly incentivized liquidity suppliers on Uniswap to migrate by using additional rewards in SUSHI tokens (which represents supplied liquidity).
While sushiswap exchange used the code of Uniswap as its foundation, it introduced some key differences. Most notably, rewards in SUSHI tokens are distributed. sushiswap exchange native token, SUSHI (which is also a governance token), is awarded to liquidity providers. SUSHI holders, unlike Uniswap’s (UNI), can still earn rewards after they cease providing liquidity.
After $1 billion in liquidity pool tokens were staked on the platform, the sushiswap exchange team initiated the vampire attack. On September 9, 2020, $840 million of liquidity was migrated from Uniswap.
Some controversy related to sushiswap exchange
10% of the SUSHI tokens were intended for the development fund, which was in complete control of Chef Nomi. One interesting fact to mention is that Chef Nomi, the sole beneficiary of the project’s admin keys, decided to sell all their SUSHI, worth approximately $14 million. This crashed the token’s price by nearly half.
After an initial attempt to justify his actions, the community lost trust in Chef Nomi’s abilities and was forced by the community to leave the project. Chef Nomi transferred control to Sam Bankman Fried, the CEO of cryptocurrency exchange FTX and quant fund Alameda Research. Thereafter, Sam transferred the admin key’s control from the exchange to a multi-signature wallet that was managed by nine people chosen by the community.
A few days after, Chef Nomi came back to apologize to the community and buy back the amount of SUSHI tokens that he had sold and then put them all back into the devfund.
The sushiswap exchange AMM
So, how to use sushiswap exchange? Let’s first understand how this application works.
sushiswap exchange is built on an AMM, which uses smart contracts to execute transactions. This model uses liquidity pools, which allow users to deposit tokens and become liquidity providers (LPs). Other sushiswap exchange can use the funds in the liquidity pools to swap their tokens. These LP users receive a small percentage from the fees generated by trades, which is how you can earn a passive income through yield farming.
Other features of the sushiswap exchange Dex include SUSHI token staking, lending, and purchasing newly launched tokens through the MISO service.
sushiswap exchange offers multichain support and includes the most popular networks, such as Ethereum, Polygon, BSC, but also newer chains like Harmony and Fantom.
Each swap needs to pay a 0.30% transaction fee. This fee is distributed among liquidity providers (0.25%) as a reward for contributing to the liquidity pool, and 0.05% goes to SUSHI token holders who staked in SushiBar (farm xSUSHI).
Note that on all DEX, traders need to set a slippage fee, which is set in percentage and is needed to cover a potential price difference between the time of your trade and the actual time the trade gets executed.
Liquidity pools
Liquidity pools are a core element of any AMM-based DEX. In order to enable cryptocurrency trading, the application needs to have those tokens available in a liquidity pool. Anyone can become a liquidity provider and earn rewards (0.25% of the transaction fee). This fee is proportional to how much liquidity they add to the pool. This is a great way to get extra yields from tokens sitting in your wallet.
Each liquidity provider receives LP tokens to represent the share of the liquidity pool. In some cases, these LP tokens can be further deposited in Farms, and this process is called yield farming.
Note that liquidity providers are exposed to the risk of impermanent loss.
SUSHI token
In the beginning, sushiswap exchange implemented a decentralized system for community governance, instead of the system used by Uniswap. The community governs the protocol. Major structural changes are made through forum discussions, official proposals, and community voting.
A sushiswap exchange developer called 0xMaki, along with a core team supporting developers, make smaller operational decisions. The community also voted on the platform’s structure and core team.
sushiswap exchange’s native SUSHI token is the foundation of its community governance. It allows holders to vote on platform proposals. SUSHI is an ERC-20 token created on the Ethereum network and has a maximum supply limit of 250 million. All 250 million tokens will be minted by Nov. 2023.
You can stake SUSHI in SushiBar to earn a proportion of the platform’s profits. These earnings are distributed as xSUSHI tokens. This is essentially SUSHI tokens purchased on the open market with the profits from the exchange.
This open market operation generates passive revenue for SUSHI stakers and also provides constant buy pressure for tokens. sushiswap exchange trades approximately $0.5 billion daily. This means that the profits from the 0.05% fees across all pools amount to around $250,000 per day.
However, 2/3rds of SUSHI tokens earned go into a lockup address and are later distributed to the LPs who earned it from the farm. As of Mar. 2022, a SUSHI token trades at around $2.9, and the market capitalization stands at $388 million, as there are only about 51% tokens in circulation (~ 127 million SUSHI), according to CoinMarketCap. You can buy SUSHI tokens using many popular exchanges, including Binance, Kraken, Coinbase, FTX, etc.
How do cryptocurrency swaps work?
Cryptocurrency swaps are very effective if you want to exchange one crypto for another without going through the time-consuming and costly process of first converting your crypto to fiat. Furthermore, by swapping cryptocurrencies directly, investors are able to access tokens with a low market cap, which may be unavailable on larger exchanges.
For instance, if you’d wish to exchange SAND for SUSHI, you would need to execute a few trades before completing this trade, as there might be no exchange that offers this specific trading pair. Investors would need to carefully plan their trades and probably use an intermediary token such as USDT to successfully execute their desired trade. However, this trade would also require the trader to pay multiple transaction fees (at least twice if your trade is SAND > USDT > SUSHI), and the value of the outcome tokens could be less due to the sudden volatility of the assets.
