Steemit Crypto Academy Season 5 [Advanced Course] Week 1 - Sunswap, Integrated stablecoin swap, Staking, Mining, veSUN, etc.

in SteemitCryptoAcademylast year (edited)



DeFi is a strong & enduring force in the crypto segment. It does solve the major problem interface of traditional finance. "Banking the unbanked" is now a reality with DeFi.

The intermediaries are completely replaced by Smart-contract in DeFi. The utilitarian value of crypto in DeFi combined with stable coin caused people to rally en masse around DeFi in 2020. The expansion of financial and business use-case together with ever-rising total locked value in DeFi is a testimony to that.

The DEX once plagued with fragmented liquidity issues for a long time got solved with the introduction of the AMM mechanism.

DeFi has been catering to the use-cases of Lending, Borrowing, Supplying assets to the Liquidity pool & earning APY, exchange, etc.

Today we will discuss as a comprehensive DeFi niche in the Tron ecosystem with a sustainable economy and decentralized Governance, Liquidity Pool, integrated stablecoin swap, stake, and mining.


AMM-DEX, Justswap is now Sunswap

The SUN.IO recently acquired Justswap, the new official domain name of Justswap with this acquisition is now The latest version of Sunswap is Sunswap V1.5.

With all other conditions remaining the same, a portion of the transaction fee is now being used to buy back & burn SUN for sustainable economy and governance of SUN.

The transaction fee in AMM-based Sunswap is 0.3%. Of this 0.3% fee, 5/6 of it is distributed among the liquidity providers and the remaining 1/6 fee is used to buy back and burn SUN.

This economic model will continue to play a vital role in the supply/demand dynamics of SUN and its platform.

Automated Market Maker Decentralized Exchange(AMM-DEX) proliferates a new era of decentralized finance mitigating the fragmented liquidity issues of traditional DEX by introducing a constant product market-making mechanism(xy=k), as a result, Liquidity Pool(LP) is created in which x and y represent the two sides of the pool.

The product of x and y at any given time is a constant.


So the equilibrium condition is XY=K.

If XY is not equal to K, the price of the asset will adjust itself to bring it to the equilibrium condition-- XY=K. That adjustment of the asset is known as the exchange rate. This is the underlying principle of AMM-based DEX.

Justswap(now Sunswap) relies on this principle to create a liquidity pool for each pair where the users are free to contribute to the pool and based on their contribution ratio w.r.t the total pool size, they earn their share.

When you contribute to a pool you have to contribute equivalent value to both sides (x & y).


AMM-DEX Sunswap creates an opportunity for the investors to pool their tokens and earn exchange fees from each trade. The exchange fee is 0.3%. In a decentralized exchange like Sunswap, the liquidity providers earn 5/6th of the transaction fees. At any given time, the fund is in absolute control of the owner.


Sun Scan

Go to On the left-hand side, you can notice a number of options-- Swap, LP Pools, Scan, SUN Swap, Burn SUN, WTRX, WBTT, etc. Click on Scan to scan the different LP pairs, their 7D and 24Hr trading volumes, fees generated, etc. Please note that V1.5 is the latest version.

From this interface, you can directly trade a pair and add liquidity. You can also track all the transactions in Sunswap from this interface.

In a liquidity pool, when you contribute to both sides of the pool, you are issued LP tokens and share 5/6th of the trading fee in proportion to your liquidity size wrt total pool size.





LiquidityVolume (24hrs)Volume (7d)Fees (24hrs)

In the last 24 Hrs, SUN-TRX Pair has generated fees of $57.4585. 5/6th of this fee is distributed among the liquidity providers, remaining 1/6th is used to buy back and burn SUN.

So (1/6)x57.4585= $9.5764 will be used to buy back and burn SUN.

Click on the vertical tab Burn SUN, located on the left of the Sunswap interface to see the entire burn history of SUN through the buyback and Burn mechanism.



LP Pools

Click on the vertical tab LP Pools, located on the left of the Sunswap interface. It will redirect you to Sunswap mining where you can find the list of LP tokens, if you have contributed liquidity to any of the LP tokens pairs, you can further stake your LP token here and start mining TRX and other Tron based coins. The mining rewards in LP stake mining vary from one pair to the other.


In Sunswap, every time an exchange happens, the trader pays 0.3% fee, 5/6th of the fee is distributed proportionally among the LP providers. The remaining 1/6th is utilized for buy-back and burn SUN.

So when you supply coins(both sides) to a Liquidity Pool, you are entitled to a Liquidity provider fee, in proportion to your liquidity contribution.

But it does not stop here. You can further galvanize your position as a Liquidity Provider and earn extra rewards on top of the Liquidity Provider Fee should you stake your LP token in Sunswap Mining.

For example, if you are a liquidity provider in the NFT-TRX LP Pool of Sunswap, you can further stake your NFT-TRX LP tokens in Sunswap mining to earn an APY of 36.91%, with TRX and NFT mining rewards.

So you earn 5/6th of the 0.3% Liquidity Provider fee in NFT-TRX Lp Pool+36.91% APY should you stake your NFT-TRX LP Token in Sunswap mining.

Please note that there may be more than 120 LP token pairs in Sunswap, but in Sunswap LP mining only a few popular LP tokens are available for Sunswap mining.

Stablecoin swap

Go to You can notice the Stablecoin swap interface. There are four TRC20 stadrd stablecoins USDT, USDC, USDJ, and TUSD. You can swap one stablecoin for any of the other three. Just select the input and output, enter the quantity, and hit the Sell button. Please note that min amount to swap is 0.01 USD, that's the beauty of Tron DeFi. It lowers the barrier to entry.


SUN Pools

Go to Click on the horizontal tab Stake. Alternatively, visit this link- has three different staking options to further earn more rewards:-

  • 3 Pool LP

3 Pool LP is a pool of 3 stablecoins USDJ, TUSD, USDT. The user needs to add liquidity in equal proportion to all three to obtain 3 Pool LP tokens.

USDC LP is pool of USDC+3 SUN. To obtain 3SUN token you can make use of the USDC pool swap facility where USDC and 3SUN can be swapped for each other. 1 USDC is equivalent to 3SUN.

SUN-TRX LP token can be obtained from Sunswap, by adding liquidity in the SUN-TRX Liquidity pool. That token can be staked here.


veSUN= Vote Escrowed SUN

The phase 2 governance mining in has already begun on 15th September 2021 and will end on 6th June 2026.

veSUN, the vote escrowed token gives users the voting rights for a specified period, and veSUN plays a vital role in the governance of Sun mining.

With veSUN, the users can boost their mining speed up to a max of 2.5x, they also earn extra rewards, as 50% of stablecoin swap fees are distributed among the veSUN holders. Furthermore, the weight of the liquidity pools in is decided through veSUN community voting. The voting snapshot is taken every Thursday at 8:00(SGT) and accordingly, the weight of Liquidity pools are adjusted.


The locking period for veSUN is from 6 months to 4 years. Once locked for a specified period, the user can not unlock veSUN until the locking period ends.

Calculation of veSUN by taking SUN

Quantity of veSUN = Quantity of locked SUN * (Expiry date - Current date)/4 years.

=> Quantity of veSUN = Quantity of locked SUN * (Expiry date - Current date)/1460 days

1 year= 365 days; 4 years= 365*4= 1460 days

Period of locking- 6 months to 4 years= 6 months to 48 months.

Quantity of veSUN= SUN(6/48) to SUN(48/48)= 0.125 SUN to 1SUN

If a user chooses a period of 4 years then he will get the veSUN same as the quantity of SUN locked. If a user locks his SUN for a period of 6 months then he will get 12.5% of the quantity of SUN locked.


3-in-1 benefits of veSUN

  • Earn TUSD(50% fee of the stablecoin swap pool)
  • Boost mining speed as high as 2.5x
  • Voting rights to decide the weight of Liquidity pools

The users who chose to stake for a period of 6 months(lower threshold) reap the least benefits whereas the user who stake their SUN for 4 years, (to obtain veSUN) maximize their benefits in terms of 3-in1 benefits.

Use Boost calculator to know how much veSUN needed to boost the mining speed:-

  • Go to
  • Select particular pool-- 3 Pool LP, or USDC LP, or SUN-TRX LP
  • Click on Boost Calculator; a pop-up will appear, enter the quantity of the LP token you want to deposit/stake, then see at the bottom how much veSUN is required to maximize the mining speed. Please note that the max mining speed that can be achieved is 2.5x.

screenshot (3).png

For instance, if I am to deposit 10 "3 Pool LP tokens", to maximize the mining speed(2.5x) I need at least 4.82 veSUN

If I stake 4.82 SUN for a period of 4 years I will get 4.82 veSUN
If I stake 9.64 SUN for a period of 2 years I will get 4.82 veSUN
If I stake 38.56 SUN for a period of 6 months I will get 4.82 veSUN


How do I swap USDC for 3SUN token using USDC Pool swap?

  • Go to
  • Select swap 3SUN, check the box
  • Enter the quantities; INPUT(From), e.g. 1 USDC, The output(To) will automatically display the approx amount.
  • Select max slippage, by default it is 0.5%. You can also customize your slippage anywhere between 0.5 to 50%.
  • Hit the Sell button.
  • Approve the transaction, sign the transaction.
