Crypto Academy / S4W5 - Homework Post for [Crypto Professor @kouba01] JustSwap

Present the Just Swap platform in your own way, demonstrating its importance within the Tron ecosystem blockchain.

Just Swap platform is a decentralized exchange that gives its users the opportunities to trade TRC-20 tokens on the Tron blockchain. It has the feature to move Tron from one user to the other and support Tronlink Wallets. On the JustSwap platform, you can swap, lend and pool tokens. This platform serves all TRON users as it supports TRON tokens. As of this moment of this post, the total value locked is $ 1,428,788,197.

What is JustSwap?

JustSwap is a decentralized system that uses USDJ stable coin, this platform can be accessed anywhere on the globe by its users. JustSwap offers security in its conversion and trading as it is an exchange protocol. The exchange method is done between TRC20 tokens, and any changes are based on the system price.

With JustSwap, you don't need to create or get verifications as login is via a decentralized wallet (TronLink Wallet). TronLink is a decentralized wallet that is supported by the JustSwap platform, and that is how you can log in. JustSwap works in a way that everything is decentralized and no intervention between transactions.

JustSwap maintains the function to ensure that all transactions are fast, secure, and safe. JustSwap supports tokens between two TRC 20 and TRX and a TRC30 token for Swap. For every submitted and successful swap, details can be viewed on Tronscan which will show as confirmed.

Its importance within the Tron ecosystem blockchain.

• Trading Service

JustSwap's underlying blockchain framework is the Tron blockchain, so the platform offers trading services like swapping tokens, Tracking tokens, Lending tokens, and Pooling in tokens. It gives the platform multi-service advantages.

• JustSwap Fees

JustSwap charges about 0.3% trading fee, which is paid as token liquidity. This fee is the same for all the tokens exchanged on the platform. Compared with some other trading platforms, JustSwap fees are low.

• Withdrawal and Deposit Fees

JustSwap has a feature called external arbitrage, where users are trading and looking at a pool for a price set. It is a situation where the user has no plans to trade but is looking for unreasonable fees which are set by the initial collection price by the first person who creates the pool. When the initial price set is unreasonable, the external arbitrage will connect to the price.

• JustSwap API

You can have access to the API for all trading pairs on the JustSap platform as the applications have parameters and the format of the return value. A request to the API is granted per person and per user for a second as the application interface has an intelligent contract API and a backend API.

Intelligent contract API has the factory and exchange contract, factory contract builds and manages the trading pairs. Meanwhile, exchange contact makes sure that there is an exchange contract for the trading pair.

The JustSwap API eases the purchase of token, swap token, transfer input by liquidity or remove liquidity, etc via the application interface contracts. Such applications can be games, financial projects, etc.

Note I mention the backend application programming interface (API), which consists of parameters that include the size and number of each page. This backend API has the return values such as quote name, base quote, base id, base symbol, base volume, price volume, base decimal, quote decimal, and error messages to be used to confirm a transaction.

• JustSwap Limits and Liquidity

Users on the JustSwap platform get updated mining schedules and are rewarded from the liquidity mining pool depending on the shares held by the different wallets. The mining rewards left over after claims have been done are shared once in 24 weeks.

A user on the JustSwap doesn't have any limit to whatever they want to Skate in, Lend, Pool or Swap.

What tokens does JustSwap support trading? How is the price of a JustSwap token determined (how it works)? Use an illustration to explain it. (screenshot required)

JustSwap supports tokens such as SUN token, TRX, USDC, SUN, SUNOLD, NFT, BTC, WBTC, ETH, WETH, WBTT, WTRX, and many more. As I mentioned above the transaction here is safe, fast with a low fee charge.

How is the price of a JustSwap token determined

JustSwap determined the price of supported tokens by using the function.

X*Y =K

X: first token
Y: second token
K: constant

From the equation, no matter the difference between the first and second token. It must be equal to K, which is a constant. It means that at any point in time, a change in one token will be auto substituted with other to have the constant result K

• Illustration

=> 20*3 = 60

=> 15*4 = 60

60 is the constant and must be equal to (203) or (154) at any point.

How do I connect my wallet to JustSwap.io? Is there a mobile app?

Before going ahead to demonstrate how to connect my wallet to JustSwap, I will state that as of the date of this post. There is no mobile application for JustSwap. I will be demonstrating using a web application for desktop.

Lunch JustSwap on a web broswer

Screenshot JustSwap

Click Connect (to initiate wallet connection), the landing page has the connect button at the top left angle of your screen and the center of your screen.

Screenshot JustSwap

Click on the wallet to select TronLink is the only option I have. To ease the process, I log in to the TronLink Wallet chrome extension.

Screenshot JustSwap

The pop window appears for the connection to be approved. I click Connect to connect my Tronlink to JusrSwap.

Screenshot JustSwap

Now we can see my Tron wallet and balance in my TronLink. It shows that my TronLink is properly connected to Just Swap and ready to perform a transaction.

Screenshot JustSwap

Include a real example of your interaction with Just Swap, demonstrating how you can trade on the platform.

One of the services on the JustSwap platform is trading, so I will demonstrate how to swap Tron to the SUN.

Note my TronLink is connected already, so I will have to select my desired tokens to swap. By default, we have Tron as my first token. The images below are failed transactions, due to a lack of Energy which is an aside from this homework task.

Screenshot Tronscan

After two failed transactions, I checked on Tronscan and did more research, and discovered the reason for the failed transaction was due to no energy. From research, I learned I needed more funds(Tron) in my TronLink Wallet. So I transfer 100 TRX.

So let move LOL

we have the first token, by default (tron) click to select the second token

Screenshot JustSwap

Screenshot JustSwap

Enter the amount, (10Tron) and Click Swap

Screenshot JustSwap

Click to confirm swap.

Screenshot JustSwap

A pop-up window is a lunch (i click Sign) to sign the transaction and approve it.

Screenshot JustSwap

Done, I finally swap 10 Tron

Screenshot JustSwap

Now I have the Sun token list among my assets in my Tronlink wallet.

Screenshot JustSwap

Include a real example of your interaction with Just Swap, explain How to add liquidity to JustSwap

Liquidity is another service offered on the JustSwap platform, which I mentioned above. After figuring out why the previous demonstration failed, I had a cool head to move on to demonstrate how to add liquidity.

Click on Pool to have the option to select the add liquidity button.

Screenshot JustSwap

Click to add liquidity.

Screenshot JustSwap

Select the token pair, my first token is tron by default which you can change if you want to use some other token. Click to select the second token to pair with the first.

Screenshot JustSwap

Screenshot JustSwap

I enter the 5 TRX, and the equivalent is generated based on the current market price. Click Supply

Screenshot JustSwap

My TronLink pops a small window to approve the transaction. Click Sign to approve.

Screenshot JustSwap

Click to confirm supply.

Screenshot JustSwap

Now, sign the transaction to approve from the small pop-up window from my TronLink Wallet.

Screenshot JustSwap

Done, I have to my liquidity pool the TRX/SUN pair,

Screenshot JustSwap

On the Pool page below the add liquidity button, my liquidity is listed below.

Screenshot JustSwap

In my Tronlink wallet, my liquidity pair is listed under the asset.

Conclusion

Well, this is not the first time I'm coming across this platform. Before saying how much I learn from the weekly courses. I will thank prof @kouba01 for this particular course on JustSwap. After two swap transactions failing, I had to do a little research to understand I needed more funds (about 100 Tron) to have a successful swap since I did not have Energy. I will have to keep burning my tron token without realizing the real problem was lack of Energy.

JustSwap can be accessed anywhere in the world by its users. Like I mentioned, you don't need an account or verification to use the platform. All you need is a decentralized wallet that is supported by JustSwap (Tronlink) to Trade, Swap, Stake, Pool, and Lend. Note, always make sure to have sufficient Energy and Bandwidth so your exchange doesn't fail.
