Hope you are all doing well. We are in week 5 of season 4 . Today i am writing homework task for professor @kouba01 which is about **JistSwap**.
# Present the Just Swap platform in your own way, demonstrating its importance within the Tron ecosystem blockchain.
With the boom in DeFi and success of UNISWAP (ETH based DEX) , gas fee on Etherium blockchain was skyrocketing. To influence DeFi, Tron blockchain launched its first DeFI token exchange in the form of JustSwap.
JustSwap is a decentralised cryptocurrency exchange based on TRON blockchain. Justswap facilitates automated transactions via smart contracts. It allows trading between TRC -20 tokens and TRX.
As it facilitate automated transactiions via smart contracts and no order matching is required, transactions are performed instantaneously. So it is better than most of other centralised platforms that have better liquidity on their own.
In addition to simple interface and low transaction fee of JustSwap, users are benefitted from share of transaction fee because the trading fee generated goes to liquidity providers directly. This ensures security and decentralised nature of the platform. Success of platform is determined by liquidity to a great extent and JustSwap is known to provide unlimited liquidity to scores of projects and traders.
Being a decentralised and open source platform, there are no intermediaries involved and that has bearing on trading fee that is as low as 0.3% . Morever, for listing any trading pair , no listing fee is required. Therefore, there is frictionless entry for all.
JustSwap marked a foundation stone of Tron blockchain into DeFi because launch of JustSwap by Just foundation paved way for many other DeFi projects such as Carrot.finance, Pearl.finance, and Salmon.finance.

### Token price determination
***
Token price on traditional or centralised trading platforms is determined by supply/demand ratio. More the demand, more is price and vice versa. Justswap uses mathematical algorithm to compute token price so that the multiplicative price of pair remains constant. Suppose we have to deposit two assets A & B.
* **AxB = constant**
Where A and B are the amount of the asset and not the price of A and B. So the liquidity provider can add liquidity as per above equation.

<sup> Above graph shows how token price varies to maintain balance</sup>
The good thing about markets that follow above model is that they are provably resistant to money pumping. No matter how much and what sort of trade is being carried out, market dynamics cannot be altered as A*B has to remain constant.
### How do I connect my wallet to JustSwap.io? Is there a mobile app? (Screenshots needed)
* Connecting TronLink to JustSwap can be achieved directly from TronLink App or from web browser like Chrome. Of these two methods , I find it simpler to connect via TronLink App. So I'll be demonstrating it with that method in a stepwise manner .
* Open TronLink App and from the bottom panel of the main page of the app, click on "Discover".
* On the next page, click on JustSwap and it will take you directly to justSwap and you are done.
* To check your connectivity , click on top right corner , a drop down menu will appear where your TronLink collection address will be seen.
* Click on this address and you got to see a notification poping up showing "Account connected to TronLink".

There is no app available for justswap. However, important Dapp links with icons are available within TronLink wallet where we can justswap easily.
#### Include a real example of your interaction with Just Swap, demonstrate how you can trade on the platform. (screenshots required)
