Technical Update—The Cycle of Building, Deploying, and Refining

Software development involves an iterative cycle of building, deploying, and refining. Drawing upon the valuable feedback we gathered during Testnet, we were able to review what we had built and therefore set enhancing trading stability as our primary objective in order to deliver an optimized and secure experience.

Trading Stability Enhancement and UI/UX Update

Refinements in the smart contract and the offer aggregator took place during this stage, so were those improvements in the user interface and the user experience design. You may not be aware of these changes in the first place, but they are the paved cornerstones that hugely contribute to the trading stability of HashgreenSwap.


Drop us a message to our Twitter or Discord and let us know how’s your experience using HashgreenSwap. And if you are interested in the technical insights of HashgreenSwap, drop a message too! We may take this chance and shed some light on the topics of the smart contract or the offer aggregator.

Liquidity Pools Now Open!

Providing initial liquidity requires you to abide by the following rules:

Singleton Aggregation Optimization: Enhancing Trading Stability for a Seamless Experience

Trading stability is of paramount importance to provide a smooth and reliable platform, and HashgreenSwap continuously strives to build a better trading environment for all green walkers within the Chia ecosystem. With this in mind, we are excited to introduce the implementation and optimization of Singleton Aggregation, a significant enhancement designed to further enhance trading stability.

Introducing Price Slippage

In this release, you now have more control over your transactions, ensuring successful execution even in volatile market conditions with the presence of Price Slippage options.


When using HashgreenSwap, you can now select a slippage tolerance that aligns with your preferences, ranging from 0.1% to 5%. This feature empowers you to define the acceptable price difference between the time of your transaction initiation and its actual execution. By choosing an appropriate slippage tolerance, you can minimize the risk of unexpected price changes impacting your trade outcomes.

What’s Slippage Tolerance?

Slippage tolerance refers to the maximum percentage price difference that you are willing to tolerate before your order stops filling or gets canceled. You can also learn more about slippage via this article written by Adam Hayes from


Please choose a slippage tolerance by clicking the setting button at the upper right corner of both the Swap and Liquidity pages. Once you have entered the desired amount you would like to trade, HashgreenSwap will display and confirm that the minimum (amount) received is guaranteed when you submit your transaction.

Select Token

With this update, navigating and trading in HashgreenSwap has never been easier. The Select Token feature allows you to effortlessly choose and search for the specific token you want to trade by simply typing its name or asset ID in the search bar. Finding your desired token is now just a few keystrokes away.


How do I search and where can I select the token?

  • Navigate to the transaction page (either Swap or Liquidity) in HashgreenSwap.
  • Hover the mouse over and click the token card (each has an arrow pointing downward).
  • A modal with a search bar will pop up with a list of tokens displayed right below.
  • Type the name or asset ID in the search bar. Once you find the token, click it to proceed!
  • If it shows “No results found”, please check your spelling and try again.

Welcome back to another update from HashgreenSwap. In today’s blog, we will introduce the latest release of HashgreenSwap v0.2 on Testnet. We warmly invite you to join us and participate in testing the newly implemented features in HashgreenSwap v0.2. Without further ado, let’s jump right in.

Click here to visit our page and start testing!

HashgreenSwap v0.2 Release

This update introduces two significant features: Overview and Dynamic Fee. We are excited to bring these additions to HashgreenSwap, alongside various smaller updates and bug fixes that have been implemented based on your invaluable feedback.

Introducing the Analytics Page—Overview


Overview is a brand new segment in HashgreenSwap v0.2 designed to provide a comprehensive overview of trading information and transaction records. With this addition, you can easily access the general trading information in HashgreenSwap, as well as delve into the details of transactions sorted by tokens and pools. Additionally, you can apply filters to explore transactions based on the type of operations performed within the AMM.



Did you know...

The total transactions conducted in HashgreenSwap on Testnet have recently exceeded 10,000!

At the top section within the Overview page, you can find the trading analytics, displaying HashgreenSwap's TVL (total value locked), total trading volume, and the overall number of transactions. As you scroll down, you can explore information regarding tokens, pools, and transactions. Alternatively, you can click on the “Pools” or “Tokens” tab to access a separate page dedicated to pools or tokens, respectively.


Within Overview, you will have access to a display of transaction records. You will be able to check each transaction’s transaction type, total value (XCH), token amount, transaction address, and the timestamp. You can also utilize the filter options to selectively display all, swap, add, or remove transactions.

Each transaction will have a transaction address. By hovering over the address, you can click on it to access additional information through



The Tokens chart presents fundamental information about each token. By hovering over a specific token and clicking on it, you will be redirected to a separate page for extra information.


Take TXCH as an example. Once you are redirected, you will be presented with information about the token, including its TVL, total trading volume, total transactions, pool information, and all the relevant transaction records. You can, conveniently, click Add Liquidity or Trade to be redirected to the respective pages.



Pools will show you the current pools available in HashgreenSwap, including pertinent details such as total volume, TVL, and APY (annual percentage yield) of each pair. By hovering over and clicking on a specific pool, it will redirect you to a separate page with further information related to the pool.


Each pool will have its own overview page where details are presented as shown in the image.

Updates on Fee

Dynamic Fee

In order to prevent transactions from failing to go through due to insufficient fees, we developed Dynamic Fee to calculate the minimum required fee for your transaction, allowing you to choose enough fee to complete your transaction. Whenever you are swapping, adding liquidity, or removing liquidity, you can choose between different amounts of network fees that are calculated and the approximated speed will be shown beneath each fee option to give you a better understanding.

You can now directly choose the network fee in HashgreenSwap. Powered by dynamic fee aggregation, the system will estimate and recommend up to three fee options with different amounts and speeds.


The aggregation process calculates the minimum required fee and provides up to three network fee options. By default, the slow option on Testnet is set to 0.005 TXCH to ensure successful transaction completion (However, the default network fee on Mainnet will be 0 XCH). For the other two options, if the calculations have minimal or negligible differences, the system will display a total of two network fee options, including the slow one.

Bug Fixes and Minor Adjustments

Based on your valuable feedback, we have made several minor adjustments in response to issues identified in the previous release. Some of the fixes implemented based on your feedback include, but are not limited to:

  • Strengthening and optimizing the user interface.
  • Ensuring that the wallet remains connected even when the page is refreshed.
  • Resolving the issue of continuous pop-up windows appearing.
  • Adding buttons to conveniently copy IDs for LP tokens in HashgreenSwap.

Our Message

We are pleased to have you join us for another update from HashgreenSwap. We would like to invite you again to participate in testing HashgreenSwap on Testnet! Your feedback and support are invaluable to us as we strive to provide the smoothest experience on the Chia blockchain.
