Good morning Chia 🌱, Chia's holders and Hashgreen's readers! We are back again for another weekly update. We are excited to share with you some updates for Hashgreen DEX, including the live market trading chart and the language support that comes back. Without further ado, let's get started!

What's Been Done​

• Live market trading chart is now officially released in Hashgreen DEX! Open your trading page and try it out for yourself! Over the past weeks, our team has dedicated to the work of visualization and the facelift of the user interface according to this new feature update.

• With the live market trading chart, you are able to click through different market pairs to view the real time changes and the history of the difference in price laid out for each market pair. You can decide on your own to select the range of time or the price scale at different intervals, and the chart will change its display correspondently to your adjustments.

• The chart will also track your mouse movements and show you the price at a certain point of time when you hover your mouse within the market chart.

• Language switch option is now back at Hashgreen DEX! It's now located at the right of the navigation bar and changed into a 🌐 button in which a drop down menu will come up and show the languages we support. Currently we have the support for English, Spanish (Latin America), Traditional Chinese, and Simplified Chinese. We will continue to add more languages in the future.

What's Rolling​

• Although we've already had four languages supported now at Hashgreen DEX, we still would like to support as many languages as possible. We posted an announcement at our Discord two weeks ago, asking for volunteer translators to help us. Up to now, we've had a few volunteers who are willing to help! And we still need more people to help! We are now looking for volunteer translators and proofreaders. If you're interested and would like to help, please visit our Discord!

We are always grateful for the help and support you provided to us, and thank you again for the love and support!

Welcome back to another Hashgreen's weekly update! Previously on Weekly Update #11 we talked about the design features that began to take shape for the AMM, hankering for the best outcome to our users and to the ecosystem. We also announced a few updates and a call for volunteer translators. If you are willing to help with the translation, please visit our Discord.

This week we will be taking you through two topics: the AMA we attended earlier this June and our thought and expectation for offer2 according to the feedback from the community.

Hashgreen at Chia in China's AMA​

What Chia is trying to solve with its NFT standards​

In the AMA held by Chia in China, we introduced our products and talked about offer features and Chia's NFT standards. Below are three factors we mentioned about Chia's NFT during the AMA, namely what Chia is trying to solve and realize with its NFT standards.

• Autonomous offer trading: to trade without authorization from a third-party platform.

  Chia does not need you to authorize a third-party platform to operate for you. This could fundamentally prevent users from getting scammed.

• Decentralized Identifier (DID): to verify the authenticity and to prove the ownership.

  Has it ever happened to you when you bought an NFT and later discovered that it was an impersonation scam? This is what Chia wants to solve with its NFT1 standard. DID is like a digital identification that confirms the authenticity. With such method, creators or project owners can have their NFTs connected with their DIDs, proving the ownership with the digital identity.

• Royalty: to pay profit-sharing to the author of an NFT.

  How many percent of royalty payment should be given to the author of an NFT is what Chia's figuring out and this is going to be one of the core ideas for NFT1.

Chia's NFT is definitely a worthy path to take and a pull factor that attracts developers, investors, and users to come, especially when there's a variety of paths such as DEX, NFT, and DeFi that people have embarked on to develop or build Chia's infrastructure.

Regardless of which path you are going to take or have taken, we, Hashgreen, are always pouring ourselves into helping these projects, including NFTs. Most importantly, providing a steady and strong base for Chia's community is what we expect and choose to do to allow all tokens in Chia to be able to trade.

Committed and Uncommitted Offers​

What we think offer2 can hold for us​

Offer files (”offers”, “offer1 standard”) have been one of the biggest drivers for the community activities in Chia, as it provides a p2p way for people to trade trustlessly and securely. As one of the first adopters of offer1, we love it so much that we start to think what we ultimately want it to evolve into based on the feedback of many DEX users. We heard these feedback:

• Why does my attempt to fulfill the offer fail?

  Ok, so this relates to how current offers are structured: they are not commitments on the chain to indicate token swap intentions, but merely a memorandum of understanding. The offer makers can withdraw their offers any second by spending the recorded coins in the offer, while you, the offer taker, have to check if the coin still exists beforehand.

  Can we make this process better? Yes! In fact, the offers should be on chain with two possible exit paths: either via settled swaps or clawback after some timeout. You can be assured that the offer is still 100% valid as long as you peek into the coins and you know for how much longer they will continue to remain valid.

• Is there a limit price I can put? Partial fill?

  No limit price. No partial fills. Ouch.

  This is most of our experience with the current DEX on Chia, and we understand it so much more. We would call it lack of feature rather than a bug for offer1, as the logic for limit price and partial fills are very custom to fungible tokens. The logic for offer1 is perfect, for example, for NFTs as they need to be exchanged in whole. We think a good offer2 design should leave rooms to house some custom logic, including things like “allowing transactions to go through as long as prices are above this price” and “self re-instantiation if certain conditions are met”.

From an AMM building perspective, we think having an offer2 that satisfies the above criteria would allow an easier exchange of funds, thus increasing liquidity and capital efficiency in the Chia Blockchain. So, rest assured folks, while Hashgreen Labs continues to build on Chia!

What's Been Done​

AMM's Design Features Explained​

Hi Chia holders! We at Hashgreen have some updates on the long awaited AMM! Over the past weeks, while we have implemented basic building blocks for the smart schemes, more importantly we are composing these blocks to ensure users have great experience trading and participating in our ecosystem.

• A sustainable token and distribution scheme for the Hashgreen ecosystem:

  We want to bake our tokenomics directly into our AMM by highly incentivizing the first batch of supporters for their rapid adoption. On the other hand, we are considering allowing not only liquidity providers to earn (liquidity mining), but also protocol owners — each and every one who owns the Hashgreen token — to earn.

• Fair pricing of token pairs:

  We all know there are huge Miner Extracted Values (MEVs) in the Ethereum ecosystem, and especially when it comes to trading, miners can easily manipulate the orders of contract interaction in their favor. Chia Blockchain does not have this problem, and we enforce a rule of single price per block to prevent market manipulation. Everyone who interacts with the AMM gets the same price and does not get front-run.

• Name your slippage tolerance and commitment period:

  When you put orders in to buy from/sell to the AMM, on top of the assured fair prices, you can additionally specify a maximum slippage tolerance you are willing to accept, and until when the order is valid. These fully adjustable parameters will make interactions with AMM a very familiar experience compared to existing ones you have used before.

There are many more design features we are currently working out! If you have questions, feel free to shoot message at our Twitter or Discord!

What's Rolling​

• Language switch option is about to be released again in the near future! As we would like to support as many languages as possible, we are looking for volunteer translators! If you are interested in providing help, please head to our Discord server and write a message in #translators or DM @HG | Daisy and @HG | James to let us know.

• Lately we've noticed that there's some impersonation scams in Chia's community and people have been affected by it. Thanks to the community's effort and your report, we were able to identify it and withdrew it from circulation in our DEX. Please be extra careful when you make any transaction, and make sure you have a full understanding of the background of the tokens you're going to trade. The effort in identifying and terminating scams is also attributed to the token listing mechanism in our DEX, where the data is reviewed after being imported from TAIL database API. We are currently working on adding warning messages in the DEX to help you and please keep careful watch for potential scams whenever you trade.

What's Been Done​

Over the past week, we've had Goby successfully integrated into Hashgreen DEX and we've also shared an interesting discovery made possible via a tool we developed that analyzes and reifies blockchain activities on Chia. If you'd like to see more of the cool graph analysis, please visit our tweet here and join the discussion.

Transaction Fee and Chia's Coin Set Model​

• We received some feedback from you related to the mechanism of transaction fee and the coin set model that Chia uses. Chia released in Chia Blockchain 1.3.4 the function of allowing makers to create an offer with a fee in order to help get the transaction onto the blockchain. According to the release, now when you want to make an offer in Hashgreen DEX, you can always add a transaction fee via Chia wallet or Goby wallet to ensure the priority of your offer in the queue. (See Best Chia Projects Bootstrapped on Hashgreen DEX for more.)

• Sometimes problems such as amount higher than spendable balance would occur when you try to make an offer. This is likely due to the characteristics of Chia's coin set model:

According to an article written by Bram Cohen, he explains in the second paragraph:

• The only persistent data is the current set of unspent coins, which have sizes and rules about how they can be spent.
• When a coin is spent it can make new coins using its value but the original coin is gone forever.

• Take the following scenario as an example: You have 20 USDS in your wallet and you'd like to create an offer to buy 1 XCH for 10 USDS.

  • Due to Chia's coin set model, your 10 USDS may consist of different coins in one package. Possibilities of the actual allocation could be: (A) one coin sized 20 USDS, (B) two coins sized 18 USDS and 2 USDS, or (C) whichever amount of coins that sums up as 20 USDS, depending on how the original transaction looks like or how many coins that are originally in your wallet. As you make the transaction, it sends the entire amount (or the highest amount of coin that you have) to the blockchain, then the change will be sent back to you.

  • In such a case where you have one single coin sized 20 USDS, your coin will be sent to the blockchain, destroyed, and split into two coins of 10 USDS, one of which will be spent, while the other will be given back to you. Before the transaction is sent to the full nodes (mempool, actually) and waiting to be included in the blockchain, you may not be able to make another offer since technically you don't have any coins available to be spent in your wallet.

  • Therefore, whenever you try to create another offer, you won't be able to do so, and that alert message amount higher than spendable balance will show up to remind you.

User ID​

• If you are transitioning from one device browser to another, you can use user ID to migrate your order and trade records. Previously on Weekly Update #6, we mentioned the function of user ID and how to use it. We would like to elaborate on this function, explaining more about the use and things for you to notice.

• Users can import trade records from one device or browser to another. Please note that user ID is bound to the browser you're using. In other words, it will vary depending on the browser or device that you use. When the data migration is done, the original user ID will become invalid, which means you can no longer see the trade records in the original one.

• Data migration will not be affected by the status of your wallet connection.

What's Rolling​

Two weeks ago we had a Twitter poll asking for your feedback about the integration of Goby wallet, and we received a handful of your feedback for the update. We would like to invite you to tell us about your thought of using Hashgreen DEX.

Feedback wanted​

• Now we are looking for users to share with us your feedback. If you're interested in helping us improving our product, drop a message in our Discord channel #ideas-and-feedback or tag @HG | Daisy and @HG | James in #general to let us know! Or you can just tell us about your feeling of using Hashgreen DEX and what can we improve directly at #ideas-and-feedback. Feedback is always wanted and appreciated!

• Example feedback questions:

  • Your experience using our DEX
  • Opinions of the functions or design we've had
  • Any idea of tools or functions that can be integrated into our product

What's Been Done​

• Goby wallet has officially been integrated into Hashgreen DEX! 🤩 You can now make or take offers for Chia Asset Tokens (CATs) directly in the browser. Enter the amount you wish to trade in Hashgreen DEX to match offers!

• We've received many valuable feedback, especially those from our Twitter poll since the release of Goby wallet integration on the testnet last week. It seems like the majority of you are all hyped up about the integration of Goby wallet into Hashgreen DEX, so am I! Our team has begun modifying and adjusting details of the integration since last week, and we will keep on making sure that Hashgreen DEX and Goby are well-coordinated.

  • We modified the notification message of wallet connection's status to give users a more definite indication.
  • We fixed the bug in which the displayed address of the wallet was not synced with Goby.

3 Steps to Trade with Goby Wallet in Hashgreen DEX​

1. Connect to Goby

2. Check wallet information

3. Start trading

• Hit the offer in Order Book to trade
  

• Make Offer directly in Hashgreen DEX
  

What's Rolling​

• Our development team is working on syncing data between different devices. We discovered the demand and benefit of syncing data across different devices, and it would be natural and more convenient for users to track their orders (i.e. My Orders in DEX), granting the fact that transactions are conducted via different devices of the same user.

What's Been Done​

• Our team has finally released an official update for the light/dark scheme in Hashgreen DEX after fixing some bugs that occurred when switching between schemes. We've also made small adjustments to the color composition of the page in different schemes to increase readability. You can set up dark mode by clicking the switch button at the navigation bar.

• We've also worked through a few bugs of the frontend interface, making sure that your feedback is received and dealt with at all times.

What's Rolling​

• Wallet integration for Goby is coming! 😍 The development team has been devoting to finalizing wallet integration into our DEX, and now we are one step away from the one-click trading experience that you've all been waiting for. Before the launch of Goby integration, which will soon be announced, we would like to invite you to help us test the wallet integration on the testnet and give us some feedback. (Instructions are given below.)

• We have also started a poll at our Twitter, inquiring your feedback of which part of the integration that you love the most and which part of it can be improved. After you've tried it out at the testnet, please visit the page, vote, and leave us a comment. You can also visit #ideas-and-feedback channel at our Discord to share with us what's your thought about it.

Follow the Steps to Test Goby Wallet Integration​

1. Make sure you have installed Goby wallet in your PC.
2. Enter Hashgreen DEX's testnet.
3. Connect your Goby wallet with Hashgreen DEX.

4. Switch from Mainnet to Tesetnet10 in your Goby wallet.
   • Open your Goby wallet web extension.
   • Go to Setting.
   • Hit Advanced Options.
   • Hit Networks.
   • Change from Mainnet to Testnet10.

5. Visit this page and paste your address (It will be a long string beginning with "txch") to collect TXCH. You may wait several minutes until TXCH is received.
6. Go back to the trading page to make offers with TFRIES/TXCH.
7. Give us your feedback at our Twitter or Discord.

What's Been Done​

• Our team has released a brand new landing page of Hashgreen DEX. Over the past week, We've renovated the look of our landing page, including a few navigation components. We've also added a live market status menu in the landing page, allowing you to instantly check upon the trade information at the landing page.

• You can browse the trading pairs or you can type in the search bar to search for the markets. Once you've identified the trading pair, you can hit the Trade button at the right end of the live status, and you will be directed to the exact trading page in Hashgreen DEX without having to select the market pair again.

What's Rolling​

• The development team has been striving to release major updates that we planned to integrate into Hashgreen DEX. In light of the situation that we decided to prioritize and focus on the major updates, the release for an optimal internationalization will be postponed. The language switch will therefore be temporarily taken down for maintenance in the near future.

• The team has been working on an update for the light/dark scheme. We will optimize the switch and release it soon.

Hello to all the readers, who have stayed with Hashgreen along the way!

My name is James, the newly hired community lead of Hashgreen. I will take charge of the Weekly Update series and carry on providing information for future product updates. Harry will still publish tech blogs from time to time, leading you through finer details of Blockchain technology related to Chia and Hashgreen.

Over the month, the Chia community seems to have been less active than before, yet with the recent release of Chia Blockchain 1.3.4. As for us, we have made a few updates on Hashgreen DEX.

What's Been Done​

• Over the past few weeks, our DEX development team has implemented multi-offer upload into the web interface to make the process of transactions quicker and easier! Users can now upload multiple offer files simply by clicking the upload button or dragging and dropping offer files directly into the page.

• A new design of open orders and order history (now called my orders) is released. It's easier now for you to check the status of your orders and even make adjustments to it with a few clicks. Details of the trade information will be shown in the display board. The two dropdown menus at the top allow you to filter certain types of offers that you wish to see. You can also cancel your offer using the cancel button in the action column. Or you can cancel multiple offers by selecting them at once.

• Our team has updated a new interface for the order book, in which we re-oriented the menu of the offers. Offers asking or bidding a certain coin will be aligned with each other. You are able to expand or close the panels, to either compare the asking and bidding price or leave the order book with only one of the offers presented.

• We have released an update for the header! We add a control button where old headers are put together with the user ID button that was temporarily removed. Light/dark scheme switch and language options are moved to the header as well.

• We've continued to iterate with new features in the DEX, some of which are dedicated to the feedback from our Discord community.

What's Rolling​

• AMM is still under slow but steady development. Enabling AMMs on the Chia Blockchain turns out to be a really hard problem! If you'd ask us when you will have HashgreenSwap to test out on the testnet, we expect it to be here in another two quarters! In the meantime, we are starting to think about the tokenomics for the Hashgreen Token, to not only allow the profits to circulate back to the community but also create an active and healthy scheme that lasts long.

• In order to ameliorate the user experience, the UI/UX team will continue to remodel the web interface. We are working hard on the new landing page besides a few more integrations!

Over the months, since the release of Chia Asset Tokens (CATs) and Offer Files, we have seen a whole herd of CATs. At the time of writing, there are 289 CATs listed on TAIL Database, 580 CATs tracked on spacescan.io, and 72 CATs traded on Hashgreen DEX.

In the past two weeks, we have implemented automatic tokens importing from TAIL Database, and starting this week, we will synchronize our CAT markets with them on a weekly basis. Original (OG) tokens that are already listed with us will receive a blue checkmark to signify that we know what party is behind the token and where to contact the issuers.

To allow users to browse over CATs more efficiently, we categorize CAT markets into several types - stablecoin, NFT-like, meme tokens, platform tokens, and Chia official tokens. You can also search for and star your favorite tokens directly in the menu, saving you time and hassle to search up the CAT.

As a DEX development team, we have seen various project teams during the period trying to engage their community in very creative ways. Specifically, there are a few different ways that we think are exciting that involve the Hashgreen DEX team in the loop, and we would like to share their experiences with you, in hopes of inspiring the future development of the Chia community.

Airdrop​

Airdropping your tokens is the best way to get traction from the community. After all, who doesn't love free tokens? There are a few project founders who have worked with us in the past to utilize our soon-to-be-released™ airdrop tools.

Niocoin (NIOC), Nine (NINE), Fund My Laptop (FML), and Zomb Studio (ZOMB) are the projects that worked with us to airdrop their tokens, under the condition that token receivers have followed their social media accounts and Hashgreen's Twitter and Discord.

Over the airdrop campaigns, we have tested several aspects of our code, including blockchain reorgs, duststorms, and our smart batch execution of airdrops. Resilience to these network conditions, and having a framework to minimize the impact of the UTXO (or coin set) model on the transaction execution are crucial for all the development teams on the Chia Blockchain.

What is a re-org (re-organization)?​

Re-orgs happen when there are temporary blockchain forks, and subsequent farmers ultimately choose one to continue, leaving the rest re-org'ed. What the users will experience is, that the supposedly settled transaction will revert from its temporarily confirmed status, and this feature of the blockchain is exactly why on Hashgreen DEX we employed a 16-block confirmation to allow you to track how sure the fund settlements are.

What is the dust storm?​

Reddit explains it better than we do, but essentially some parties are spamming useless transactions on the blockchain, creating congestion and fee market at the same time. To note, this is perfectly normal - there is nothing shady with creating a dust storm, as blockchains are built to withstand these transaction requests. The dust storm transformed the Chia Blockchain into a place where all project developers and users are required to be aware of fees, which is healthy and sustainable.

To summarize, here are some catches with airdrops:

Peer-to-Peer Token Offering​

There is a load of exciting NFT projects going on on the Chia Blockchain! While the NFT standards are still under development, a few token communities are already offering fungible tokens that are promised minting rights, and some of them bootstrapped their NFT projects on Hashgreen DEX!

Space Marmots Premium (SM1) and Ultimate Farmer Club (UFCG) worked with us to utilize our market and order book API to automatically provide peer-to-peer offerings to the users. They combined have more than 100 successful token sales on Hashgreen DEX, and these events were very successful due to the project development teams' swift actions and a diverse set of capabilities that our trading API provides.

Catmosphere (CATMOS) employed a cool strategy where they not only were selling their token at a price of 0.0010 XCH, but also offering a buy-back at 0.0011 XCH. All of these were done programmatically, and users can buy/sell the CATMOS token at will. The offerings provided an anchor to the price of CATMOS, and brought interest into the Catmosphere community and Hashgreen DEX. Over the period, CATMOS was even the most traded asset on Hashgreen DEX!

What can Hashgreen DEX API do?​

We offer a variety of functionalities from market exploration and public order book information, to private order management. The market statistics endpoint which provides real-time token price information and capitalization, is now being used by TAIL Database and XCH Universe (Let us highlight you by reaching out to [email protected] if you are also using them!).

Trivia​

As many project devs have found out, community members love to accept challenges to pick their brains!

Space Marmots Premium (SM1) and Easter Egg (EGG) ran their exciting trivia events respectively on Groundhog Day and March 9th. Their formats are not exactly the same, but both involve a series of meticulously designed questions that lead to some web pages, further pointing to more carefully hidden links with steganography. In these links, community members can find their offer files for the CAT as a sweet reward.

We at Hashgreen had much fun co-hosting and spreading these events, and were more than happy to work with any project devs!

Summary​

We talked about three different ways to kick start your Chia Asset Token (CAT) project: airdropping, peer-to-peer offering, and trivia games. There are a lot more CATs we are trading now on Hashgreen DEX, and we conveniently categorized them for you: stablecoins, NFT-like tokens, meme tokens, platform tokens, and official Chia tokens. We believe it is an exciting exploration scrolling through the different categories, and maybe you can find another cool project to follow in the long run!

What's Been Done​

• Over the past weeks, fees on the Chia Blockchain seems to be here to stay. To allow our users get their transactions on chain quicker, we now provide users with the ability to supply fee by adding to the supplied Chia amount or removing from the requested Chia amount in their offers. The suggested fee is hinted on the pop-up window for order book items, and is currently 0.0001 XCH. We chose this number since it not only suffices to be on top of the mempool, but is miniscule (7 cents USD at the time of writing) for users. In the future, we plan to implement more accurate fee estimators to give better fee hints and save you some bucks.

• We made it easier for users to submit your orders! Simply copy the amounts provided in the pop-up panel when you hover on the offers you want to match against with the copy button. You can also paste your offer file string directly on the web interface.

• Many partners are starting to integrate our Market Statistics API into their platforms. The previous generation were slow and bulky, taking nearly 30 seconds to complete a call. We have optimized it to return the results in under half a second.

• New market selection menu is now available at UAT interface. If you want the UAT interface to connect with mainnet, head to UAT settings and toggle on PROD.

• We fixed many bugs on the frontend interface, including incorrect display of order status (sometimes it shows "Confirming undefined"), and user token retrieval errors.

What's Rolling​

• The smart coin team is coding up the first version of AMM coin driver for an MVP AMM protocol. As time goes on, we will gradually implement more standard functionalities in current AMMs!
