Technical updates As a temporary solution until the new and improved KYC-procedures are implemented, we have lifted the daily trading limits to 100k for both available KYC-levels. Several node issues have been fixed after the GETH update as a preparation for the Ethereum Fork. These updates caused a few challenges with WAVES and VRS, which have been resolved by now and are working as usual. QTUM deposits have been disabled in order to be moved to the main net and to be swapped from ERC20. You will receive further updates from us about this soon. We'd like to bring to your awareness the fact that the current Devs team is working almost 24/7 to address customers' and the system issues. We are hiring more team members in order to improve the whole process and are carefully selecting the qualified personnel here in Singapore which is not so easy to find these days. Additionally, we now have a separate team handling the UI that we aim to improve over the coming weeks and months. We are currently narrowing down our focus to address the issues at hand and to make the necessary improvements. We believe that this is the most optimal approach to a project as vast as COSS that will inevitably become a one-stop solution platform for crypto. For now, our major goal is to enhance the Exchange that will serve as a foundation for improving the Payment gateway / POS system. Once these two are solidified we will be able to add as many layers as necessary to increase the functionality of the platform. Our sincere thanks go to all for you who are patient enough to allow the required time for these changes to happen. User Interface (UI) We are totally aware, and fully understand the urgent need for the UI improvements. The necessary steps to make upgrades in this area are being made. A local team from Singapore have been assigned to work both on the brand-new UI design including both the normal and the advanced modes covering both the needs of the new traders and the more experienced ones who require the professional tools. This process has our highest priority at the moment, and sadly, cannot be done overnight.

ERC20 DAO is live The first DAO went live for distribution of ether (ETH). The conversion of non-ERC tokens has also been deployed. Please take notice of the following conditions for using it below: • To call the DAO you need to have ETH in your COSS wallet; • The fee for calling the DAO is 0,002 ETH; • The minimum withdrawal amount from the DAO is 0,01 ETH; • The non-ERC tokens (e.g. BTC, ARK, LSK, NEM, etc.) are converted into ETH; • There is a separate DAO for each of the ERC20 tokens. Matching addresses for Token-Based Fee Split Allocation Many COSS customers have deposited the tokens to the wrong wallet addresses: e.g. ETH to COSS wallet, SUB to ETH wallet, BTC to BCH. Many of these issues have now been resolved, however, there is still a list that has to be completed. The matching between the tokens and the wallet addresses is done manually and is therefore time-consuming. Please rest assured that the matching will be fixed in the due time. Please note that COSS or other tokens sent to the CONTRACT address cannot be retrieved. All the other cases have been included in a spreadsheet and are being solved one by one. We expect them to be sorted out completely within the next week. If your case has not been solved within the next week, you will need to re-submit your query by emailing support@coss.io. We will then check your case in the spreadsheet ensuring that it is not missing. We also encourage you to read the following article on how to track your COSS Token-Based Fee Split Allocation on Medium: https://techburst.io/how-to-track-coss-io-fee-split-allocations-with-cointracking-801e477cfecd To get ready for the next COSS Token-Based Fee Allocation Split please study the tutorial here. Exchange The challenges with the WAVES and VRS tokens have been resolved successfully and should be working normally by now. Over the weekend we have passed 23,000 trading accounts on coss.io and numbered over 2600 users on our Slack community. Trading of the following pairs is now available on www.coss.io:

ENJ/BTC

ENJ/ETH

KIN/BTC

KIN/ETH

LINK/BTC

LINK/ETH

VEN/BTC

VEN/ETH We will also be looking into NEO including GAS distribution. Security measures Lately, there's been lots of malicious screening for weak passwords. We have received lots of emails reporting that there have been attempted logins with IP's from multiple locations which did not match the locations of the users. Please note that one of the IP's should always be from Cloudflare and the other one should always match yours. If it doesn't happen, be suspicious and undertake the necessary security measures. Check the IP address here: https://www.iplocation.net/. Report on the IP that doesn't match so we can block it. We encourage you to enable the two-factor authentication (2FA) in order to secure your COSS account login process

Please note that there are many hackers who screen for weak passwords these days. Stay safe! Best, Your COSS Team
