:dart:Project Goal:

To create a secure decentralized app that introduces a new level of trust and transparency in the DeFi and gaming spaces on the TRON ecosystem through reliable price data from oracles and verifiable randomness.

By leveraging ChainLink VRF and ChainLink Price Oracle, we aim to establish a platform where users can engage in a Prediction Market and a variety of exciting games & modes, all using real-time price data (DeFi) and providing provably fair outcomes ā€” an innovation currently lacking in the TRON space.

This project will empower users to participate with confidence, knowing that:

  • all outcomes of the Prediction Market are reliable & the price data is real and trustworthy;
  • all game results are generated in a trustless manner.

All of this fosters a vibrant community centered around fairness and transparency in both DeFi and gaming.

:link:Project Value:

This project utilizes cutting-edge blockchain technologies to create a transparent, secure, and trustless environment for users to engage in a Prediction Market (DeFi) and a variety of games where they can try their luck.

Integrations:

  • Chainlink Data (Oracle):
    This integration enables accesing real-time data directly from multiple trusted sources. By utilizing Chainlinkā€™s decentralized oracles, we can ensure that users receive the most up-to-date and trustworthy critical information ā€” such as prices, statistics, etc. This creates a robust environment for delivering fair and engaging experiences.

  • ChainLink VRF:
    This integration provides verifiable randomness, ensuring that game outcomes are fair and trustworthy. By utilizing ChainLinkā€™s VRF, we can guarantee that results are generated in a secure and tamper-proof manner.

  • LayerZero:
    A protocol designed to facilitate communication between different blockchains, aiming to enhance interoperability. Its main purpose is to enable seamless cross-chain transactions and interactions, allowing decentralized applications (dApps) to operate across multiple networks without friction.
    In this project, LayerZero is used to bring Oracle Prices & VRF responses to the TRON chain from the chains where the ChainLink Oracle & VRF coordinator are deployed.
    By utilizing LayerZero, the project demonstrates the valuable cross-chain interoperability between EVM-compatible networks and TRON, creating numerous opportunities for innovation within the TRON ecosystem.

  • TronGrid API:
    This powerful API is utilized to access blockchain data from the TRON network, including both mainnet and testnets. It facilitates the retrieval of smart contract historical data and real-time event listening, ensuring access to the most accurate and up-to-date information available from the blockchain for project development.

Through these strategic integrations, the project aims to create a robust and engaging environment for users in the TRON network, setting a new standard for trust and transparency in DeFi and gaming.

:orange_book:Project Test Instructions:

  • Open the website.

  • Connect your TronLink wallet

  • Switch to Shasta Testnet Chain

  • Go to the Faucet page to claim some $LUCKY tokens, which are used for participating in prediction market and games. On this page you can also find a link to obtain TRX coins on the TRON Shasta Testnet, which are necessary for paying transaction fees.

  • Bull or Bear: :ox: / :bear:

    1. Navigate to the DeFi page and select ā€œBull or Bearā€;
    2. Select a market from the available list [BTC, ETH, etc] to specify which asset you want to bet on;
    3. The round page will show a progress timeline, allowing you to see the current stage of the round and the steps that have been completed;
    4. You can bet only during the prediction window (after the round has started and the initial price has been set). During this time, youā€™ll see a countdown timer and the settlement time, which indicates when the final price will be fetched. You will be presented with a question asking where the price will be at the settlement date compared to the initial price. You need to input your bet amount and make a prediction of either ā€œBullā€ or ā€œBear.ā€
    5. Once the prediction window closes, the round enters the phase of awaiting settlement. During this period, you cannot make any further predictions. When the settlement time arrives, the final price will be determined. At this point, you will be able to see the outcome of your prediction and check if you were correct.
    6. If your prediction was right, you can claim your rewards.
    7. Additionally, there is a ā€œRounds Historyā€ page that contains all past rounds, where users can open and view round details.
    8. An FAQ section is also included, providing helpful information about the game and its mechanics.

  • Ticket Lottery Game: :ticket:

    1. Navigate to the Games page and select ā€œTicket Lotteryā€;
    2. When you open the Ticket Lottery page, it will load the details of the last round, which may be active (running) or in another status, such as ended and waiting for the VRF response.
    3. The round page will also show a progress timeline, allowing you to see the current stage of the round and the steps that have been completed;
    4. You can only buy tickets for an active round, and a countdown timer will indicate how much time is left to participate.
    5. Select the number of tickets you wish to purchase (note that a maximum number of tickets allowed for each round will be specified on the page) and complete your purchase using $LUCKY tokens.
    6. After buying your tickets, wait for the timer to expire.
    7. Once the timer expires, the round will move to the next stage. If no one joined the round, it will simply close, and a new round will start. If you are the only participant, the round will finalize, and you will automatically receive your funds back in $LUCKY tokens. However, if there are multiple participants, the round will enter the VRF requesting phase, which may take some time. After the random number is obtained, the winner will be chosen, and they will receive 100% of the round pool automatically. Rest assured that if there is a significant delay in receiving the VRF response, participants will be able to claim back their funds.
    8. Additionally, there is a ā€œRounds Historyā€ page that contains all past rounds, where users can open and view round details.

Here are two questions about the ā€œBull or Bearā€ betting process on the DeFi page:

  1. What factors should a user consider when deciding whether to predict ā€œBullā€ or ā€œBearā€ for a specific asset during the betting window?

  2. How does the countdown timer and settlement time affect the userā€™s betting strategy and decision-making process?

Hi @Nweke-nature1.com.

Itā€™s important to clarify that LuckyDapp is not a betting or gambling platform.
Actually, LuckyDapp is designed specifically within the DeFi space and currently features a Prediction Market called ā€œBull or Bearā€, where users can predict price movements of crypto assets like BTC, ETH, TRX, MATIC, etc. (with plans to expand to fiat currencies, stock markets, and more).

It also includes various VRF games with outcomes determined by verifiable randomness.

This unique combination emphasizes trust, transparency, and community engagement within the decentralized finance ecosystem, positively impacting the TRON ecosystem.

Hi @ines_valerie .

Thank you for this question. In future plans, several strategies are outlined to enhance ecosystem partnerships and expand user reach. Here are some specific initiatives being considered:

  • Collaborations with existing projects on TRON:
    To enhance user reach and create valuable partnerships, there are several potential collaboration opportunities. [If any project wants to collaborate, letā€™s talk].
    Here are a few examples:

    • Listing on JustMoney Explorer: Collaborating with JustMoney Explorer - the best dApp explorer found in the TRON ecosystem, could significantly increase visibility. Kudos to the team for their great job!
      There may also be opportunities to integrate their token, $JM, as an option for participation in LuckyDapp future features;

    • Partnerships with TRON Energy markets / Tools: Analyzing the forum revealed several awesome projects that could be potential collaboration partners to reduce transaction costs for users;

  • Social media engagement: Actively participating in AMAs and Twitter Spaces will help highlight the project and its unique features. Showcasing integration with the LayerZero team will demonstrate the smooth cross-chain interoperability between EVM chains and TRON, positioning the project as a pioneer in this area and boosting social media presence;

  • Highlighting ChainLink integrations: With the integration of ChainLinkā€™s Price Feeds and VRF, seeking listings on ecosystem dApps directories will enhance credibility and attract users interested in reliable and innovative DeFi solutions.

Implementing these strategies aims to create a strong user base and establish LuckyDapp as a significant player in the TRON ecosystem.

Hi @manfred_jr .

Yes, you understand totally correctly the goal of LuckyDapp.
Iā€™ll briefly discuss the security protocols to safeguard user funds and data for both the DeFi Prediction Market and the gaming features to give you a comprehensive overview:

  • DeFi Prediction Market:

    In the Prediction Market, users can make ā€œBull or Bearā€ predictions based on real-time data. The platform leverages ChainLink Data Feeds, which are trusted oracles ensuring that all price data is accurate and tamper-proof. The outcomes of predictions are fully verifiable on-chain, allowing users to confirm the results independently. This integration provides transparency and reliability.

  • VRF Games features:

    Regarding the gaming aspect, LuckyDapp utilizes ChainLinkā€™s Verifiable Random Function (VRF), a leading provider of verifiable randomness in Web3. This means that winners in games, such as the Ticket Lottery, are selected in a completely random manner, which users can also verify on-chain. This guarantees fairness and ensures that all outcomes are determined without bias.

  • Cross-Chain security & User protection:

    In both cases, ChainLink features are integrated into TRON using LayerZero, a cross-chain messaging protocol. This not only enhances interoperability but also ensures security. Users can be assured that if there are any issues with the delivery of cross-messages to or from TRON, or if there is a timeout in response, the smart contract logic is designed to refund their funds, thereby safeguarding their investments.

Overall, these security measures aim to create a robust and trustworthy environment for all users on the LuckyDapp platform.

Hi @Chukseucharia .

Thank you for your question. At the time you wrote this, the project details were still being finalized, but now all the information is available.
For a better understanding, you can read the "Project Test Instructions" section or watch the video demo: https://www.youtube.com/watch?v=2ztfrP1ZVBc

In simpler terms:

LuckyDapp is a decentralized platform within the TRON ecosystem that combines elements of DeFi and gaming.

  • DeFi (Prediction Market): Users can predict the price movements (Bullish or Bearish) of cryptocurrencies like BTC, ETH, TRX, MATIC, etc. If their predictions are correct, they can claim the reward based on their stakes.

  • VRF Games: The platform also includes games, where outcomes are determined through verifiable randomness, ensuring fair play.
    For example, thereā€™s a Ticket lottery game where participants buy tickets during the buying period. At the end of the round, one winner is selected in a random manner, generated with VRF, and receives the entire prize pool.

If you try it, feedback would be appreciated. :pray:

More updates coming soon.

Hi @Smart1 .

  1. Deciding between ā€œBullā€ or ā€œBearā€ is ultimately up to the user. One important factor to consider is market trends: understanding whether the market is bullish or bearish overall can guide their decision.
    Additionally, personal risk tolerance is crucial: users should consider their own risk appetite and investment strategy when making their predictions.

  2. Iā€™m not quite sure what you meant by this question. The countdown timer simply shows how much time is left until the prediction period closes or the settlement time arrives.
    I donā€™t know if you checked the website, but below, Iā€™ve attached an image of how the countdown timer looks on the platform.

Hi @Relate101

LuckyDapp is fully responsive, allowing access from any device, including mobile devices. Users can enjoy the platform seamlessly on their smartphones or tablets.

If youā€™re asking about a native mobile application for Android or iOS, there are currently no plans for that, but it could be considered in the future. At this stage, the responsive web app is believed to provide the necessary functionality and user experience without the need for a separate native app.

Iā€™ve attached few images of how the web app looks on a mobile device for your reference.
