How to Buy and Stake Opu Coins


Users of Opu analyze their health and skin image data and are rewarded for sharing and whenever the data is accessed for research purposes. By creating a balanced win-win relationship in which all parties benefit from access to health and wellness data, OPU will become a standard means of exchange for data within the healthcare industry.

To accomplish this, the OPU platform has its native cryptocurrency – OPU coin.

How to obtain OPU coins, you ask? Tag along. In this explainer post, we will discuss three ways to get OPU coins.

Let’s get started!

How To Buy OPU Coins Using QuickSwap?

QuickSwap exchange is built on layer 2 solution – Matic network. Thanks to this, the transactions are lightning-fast, and most importantly, you pay minimum transaction fees. In this section, we will buy some OPU coins against ETH using the QuickSwap exchange.

Step 1 – Connect Your Metamask Wallet to Matic Web Wallet

  1. Go to Matic web wallet.
  2. Click on the Metamask option and connect your Metamask wallet to the Matic web wallet. Once you have done that, the Matic wallet dashboard will be displayed on your screen.

Step 2 – Add Funds To Matic Web Wallet

  1. Click on the ‘Move funds to the Matic Mainnet’ dialogue box.
  2. Now choose the cryptocurrency you wish to send from Ethereum mainnet to Matic mainnet. For the sake of this tutorial, let’s select ETH.
  3. Above the ‘Transfer’ button, you will see the ‘Transfer Mode.’ Please select the ‘PoS Bridge’ by hitting the ‘Switch Bridge’ button. PoS bridge will allow you to transfer funds from Ethereum mainnet to Matic mainnet within 10 minutes. (The Plasma Bridge might take up to a few days.)
  4. Select the amount of ETH you wish to add to the Matic mainnet.
  5. Now hit the ‘Transfer’ button.
  6. A dialogue box will appear highlighting ‘What’s supported’ and ‘What’s not supported.’ In the ‘What’s supported’ section, you will see that moving funds from Ethereum to Matic will take around 7-8 minutes. Click on ‘Continue.’
  7. The ‘Transfer Overview’ prompt will open. You will see the total deposit amount after slashing a small gas fee. The gas fees here are much cheaper than Uniswap or 1inchExchange.  Hit ‘Continue.’
  8. The last dialogue box, ‘Confirm Transfer’ will pop up on your screen. Review your transaction. You will see the amount of ETH being transferred, the transfer mode – PoS Bridge, and the estimated transaction fee. After you have read these details, click ‘Continue.’
  9. Once you hit ‘Continue,’ the Metamask window will open up. Adjust the gas fees and hit save. Next, click ‘Confirm’ to process the transaction.
  10. The ‘Transfer in Progress’ window will show up on your screen. Wait for 8-10 minutes, and your transaction will be completed. You can check the status of the transaction on Etherscan by clicking the ‘View on Etherscan’ option at the bottom of the ‘Transfer in Progress’ window.
  11. Once the transaction is completed, go back to the Matic wallet, and you will see that your ETH balance is added to your Matic wallet.

Step 3 – Swap ETH for OPU Coin on QuickSwap

Before we start swapping ETH for OPU tokens, we will first add Matic Network to Metamask. Then we add the OPU coin to the Metamask wallet. Finally, we will swap ETH for OPU.

Let’s get started.

Adding Matic Network To Metamask

  1. On the top right corner of Metamask dashboard, click the Network Selection dropdown menu located on the left-hand side of the wallet icon.
  2. From there, select ‘Custom RPC’. A form will appear with two tabs – Settings and Info.
  3. Go to the ‘Settings’ tab.
  4. Now, add the relevant details in the input section – a) In the ‘Network Name’ box fill Matic Mainnet. b) Now, paste in the ‘New RPC URL’ field.
  5. You can also fill the optional fields – a) In the ‘ChainID’ field type 137, b) In the ‘Block Explorer’ input section add, c) To avoid confusion while switching networks, enter ‘MATIC’ in the ‘Symbol’ section
  6. Now scroll down, hit ‘Save’, and that’s it. You have successfully added Matic Network to Metamask.

Adding OPU Coin to Metamask

  1. On the Metamask window change network settings to ‘Matic Mainnet’. For this, select ‘Matic Mainnet’ from the network selection dropdown menu.
  2. On the main Metmask account page, click the ‘Assets’ tab. At the bottom of the Assets window you will find the ‘Add Token’ button.
  3. Select ‘Add Token’. A window will appear with two tabs – Search and Custom Token.
  4. Hit the ‘Custom Token’ tab. Once you select Custom Token, an input dialogue box will show up.
  5. Go to and search for OPU coin. You will find OPU Coin’s contract address and other relevant details. From there, copy the contract address of the OPU token.
  6. Now, come back to the Metmask window. Paste the copy contract address in the ‘Token Contract Address’ field. If you’ve pasted the correct address the ‘Token Symbol’ field will automatically show up.
  7. Hit ‘Next’ and then select ‘Add Token’. And that’s it- you have successfully added the OPU token to Metamask.

Currently, your OPU balance in your Metamask ‘Assets’ section will be zero as you haven’t purchased any OPU tokens. So let’s now buy some OPU coins using QuickSwap.

Swapping ETH for OPU tokens On QuickSwap

  1. Go to the QuickSwap Exchange.
  2. Go to your Metamask wallet and change the network settings to ‘Matic Mainnet.’ For this, open the Network Selection dropdown menu. From there, select the ‘Matic Mainnet’ option (or whatever you named the Matic network while adding it to Metamask).
  3. Now go to the QuickSwap dashboard, and you will see your Metamask wallet is automatically connected. If not, click the ‘Connect to a wallet’ option on the top right of your dashboard. Now connect your Metamask wallet manually.
  4. Now back to the QuickSwap window. In the ‘From’ section, select ETH, and from the ‘To’ section, select OPU.
  5. For the sake of this tutorial, let’s buy 0.01 ETH worth of OPU coins. Enter 0.01 in the ‘From’ section, and the transfer amount will be automatically displayed. At the time of this writing, 0.01 ETH will give you 3156 OPU coins.
  6. Click ‘Approve ETH.’
  7. Metamask will open up. Hit ‘Confirm.’
  8. The QuickSwap user interface will change within a few seconds to ‘Approved.’ Click ‘Swap.’ The Metamask will open the ‘Confirm Swap’ window. There hit ‘Confirm Swap.’ Again ‘Confirm’ on the Metamask pop-up, and that’s it. Your transaction will be completed within a few seconds.
  9. Once the transaction is completed, you can check the OPU balance under the ‘Assets’ section of your Metamask wallet.

How To Buy OPU Coin On ChainX?

ChainX is a centralized exchange located in Korea. ChainX supports KRW fiat pairs and few crypto-to-crypto pairs. In the case of OPU coins, there are two trading pairs on ChainX – OPU/ETH and OPU/KRW. For the sake of this post, let’s buy OPU coins against ETH.

  1. Go to the ChainX website. Sign up with ChainX by entering your details.
  2. Now log in to your account.
  3. To purchase OPU coins with OPU/ETH pair, you need to sell OPU/ETH to KRW.
  4. Enter the sell section. You will see the token price on the left. Select the right sale price and enter the value. Now hit the ‘Sell’ button. Now you can go ahead and buy OPU coins. It is the same as ‘Sell.’

OPU Coin Native Staking Program

If you have some OPU tokens, you can earn passive income in OPU coins by staking them in the OPU native staking program. You can earn up to 30% on your OPU holdings. You can earn staking rewards by locking your OPU coins directly using your OPU wallet.

Here’s how it works –

  1. Open your OPU wallet and go to the staking window.
  2. Enter how many OPU coins you wish to stake.
  3. Now, choose the staking duration from the dropdown menu.
  4. Select the type of staking – Locked or Unlocked.
  5. Verify your account password and hit ‘Stake.’ That’s it. You have successfully staked your OPU coins.

Now let’s take a look at the staking rewards rates. It is based on the type and duration of staking.

Recent AMAs Recap

The Opu Labs team recently participated in a number of AMAs. Here is a recap of the discussions.

Healthcare is one of the most well funded sectors in the developed world. There are estimates that most governments channel a minimum of 30% of their GDP to healthcare. Opportunities in the healthcare system are also on the rise. Despite the ravages of the pandemic on the global economy, healthcare investments are increasing at unprecedented levels.

Data shows that in 2020, equity funding in this sector hit the $80.6 billion mark in Europe, North America, and Asia. However, while healthcare receives a massive amount of funding and support, it has many inefficiencies. Its complexity and intricacies have left some of its processes in the stone age, as other areas embrace innovation.

As an illustration, the medical field has had excellent progress in developing vaccines, diagnostic technology, and drugs. In sharp contrast, facets such as data analysis, patient data, supply chain, and drug traceability management are in the dumps.

Additionally, threat actors are also bringing the medical cybersecurity sector to its knees as phishing attacks, and fraud schemes escalate. These malicious actors prey and extort medical enterprises after succeeding in their data exfiltration schemes.

To illustrate this point, in the Blackbaud ransomware case, hackers stole the personal data of over 10 million patients from the third-party cloud computing business. This vendor has affiliations with Inova Health Systems, MultiCare Foundation, and Northern Light Health Foundation.

Why Opu Labs is Building a Healthcare Blockchain Project

Blockchain technology can revolutionize the healthcare industry and eliminate the inefficiencies and risks that accompany medical data handling. Industry respected proponents of the technology, such as Opu Labs, look to blockchain technology not just as a problem solver but as a value addition development.

To this end, Opu Labs is building secure and scalable blockchain infrastructure for the health sector. Opu Lab’s apps and services will empower manufacturers, patients, researchers, and medical personnel with tools that seamlessly manage, monetize, control, and monitor the usage of medical data.

Opu Lab’s blockchain applications will eliminate the shortcomings of the centralized electronic health data system. In research, for instance, out decentralized data storage systems will free patient data from the clutches of private networks or organization servers.

By eliminating personally identifiable markers on data through encryption, researchers can retrieve valuable data from millions of patients without breaking any confidentiality laws. This feature will lead to more remarkable advancements in research, public health management, and adverse event identification.

Through Opu Lab’s robust blockchain systems, patients can share their private keys with health care providers at will. An interoperable patient data management system ensures accurate, rapid, cheaper, and superior patient care.

The use of smart contracts can create data access authorization protocols, keeping health records away from malicious actors. The OPU blockchain platform will leverage its mobile applications to enhance patient self-monitoring.

The Opu Coin (OPU) Unique Selling Proposition

Most blockchain startups kick off their operations with nothing more than a white paper and a determined project team. Opu Labs has all these aspects and the benefit of years of experience in the health and personal care sector.

Opu Labs has seen success in the skincare industry via its artificial intelligence-powered facial technology platform. Utilizing the Opu AI system, the business has forged meaningful partnerships with companies and healthcare professionals.

The project has a data analysis, capture, and comparison system in place. As an illustration, we have a collection of over 25,000 images from users and 50,000 skin profiles. Using this system, the Opu AI can successfully evaluate a user’s levels of acne, wrinkles, redness, and hyperactive pigmentation.

Opu Labs’ partnership with Acnoc, for instance, built a body of evidence from users proving that Acnoc ‘s ALL HYBRID ESSENCE could reduce acne. In their 14 Day Acne Free Challenge, the award-winning brand used Opu User tests to establish an 82% reduction in acne amongst their product’s users.

Kosé India used the Opu Challenges tools, powered by Opu AI, to test their Spawake Pimple Solution Purifying Serum. Results collected using Opu AI showed that the product had a 90% success in improving acne and the condition of the skin.

The Opu Labs Future

Opu Labs is now refining the project’s AI  technology for other  purposes. The Covid-19 pandemic had a lot of influence on Opu Labs’ decision to launch our viral skin analysis program.  The Opu Viral Skin Scanner AI  showed a 75% accuracy in diagnosing virus-related skin conditions. The initiative is still running and for all images collected, the company will donate a certain number of OPU to research in COVID-19.

Opu Labs’ primary focus is on data analysis rather than medical diagnosis in order to assist users to manage and monitor their wellness. The company observes privacy and financial regulations in the jurisdictions where it operates.

The OPU Network

The value-driven Opu Coin (OPU) network focus is on the healthcare industry. Through Opu Coin (OPU), stakeholders in the health field can share their data and earn OPU tokens in return. Therefore, the token will help build a data-sharing economy that will incentivize all users and become a key healthcare sector data exchange resource.

Opu Labs first launched their project on the Ethereum network. The Opu Coin is, therefore, an ERC-20 token. However, following the dismal network performance of the Ethereum network and consequent high transaction charges, Opu has moved its blockchain operations to the faster Matic network.

Matic is a scalability platform that powers Ethereum based projects giving them speed and cost-effective transactions. The Matic network can confirm transactions in 2 seconds or less and only has nominal charges. The Opu ecosystem can now build its health care data sharing, payments, and data privacy network on the lightning-fast Matic network.

The near-zero gas fees of the Matic network will also help onboard more health care professionals, patients, manufacturers, and researchers into the Opu network. The Opu project is currently focusing on completing the development of its core components.

Currently we have a functional web platform with liquidity and staking features. The OpuCoin $OPU is on QuickSwap, offering an excellent price opportunity for early adopters. The Opu App is currently available on Google Play. The iOS version is under review and will hopefully launch soon. The Opu Platform also has APIs for 3rd party developers to use. The Opu Coin project has therefore progressed well beyond the whitepaper stage.

To create a more extensive user base and build a vibrant community, the team is creating a robust social media presence. We have over 150,000 users signed up on the site. The user base holds close to 100 million OPU coins.

Why You Should Hold OPU Tokens

OPU coin works as a utility token on the blockchain, rewarding  users and other ecosystem players.  The OPU Marketplace has choice rewards and discounts for Opu Coin holders. In the future, the Opu Coin will work as a data sharing and access incentivization token.

The Opu Labs project has a solid use case and working products. It is a project with proven progress in its roadmap.  Opu Labs blockchain dapps and services will help to decentralize healthcare data access. Running estimates are that blockchain technology can save the healthcare sector close to $150 billion in IT operations, data breaches, and support annually.

For this reason, the use of blockchain technology in the healthcare sector will grow at a 67.1% rate by 2023, from $44.6 million in 2017. Many healthcare-related blockchain projects rarely see the light of day. Opu Coin (OPU) is outdoing this grim statistic as it is already operating based on the support of our community, partners and investors.

You can purchase OPU on these supported exchanges.
