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 — 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.
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 Chainlink’s decentralized oracles, we can ensure that users receive the most up-to-date and trustworthy critical information — 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 ChainLink’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.

Project Website: soon
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:
- Navigate to the DeFi page and select “Bull or Bear”;
- Select a market from the available list [BTC, ETH, etc] to specify which asset you want to bet on;
- 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;
- TBD
- TBD
- Additionally, there is a “Rounds History” page that contains all past rounds, where users can open and view round details.
- An FAQ section is also included, providing helpful information about the game and its mechanics.
-
Ticket Lottery Game:
- Navigate to the Games page and select “Ticket Lottery”;
- 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.
- 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;
- You can only buy tickets for an active round, and a countdown timer will indicate how much time is left to participate.
- 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.
- After buying your tickets, wait for the timer to expire.
- 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.
- Additionally, there is a “Rounds History” page that contains all past rounds, where users can open and view round details.
- An FAQ section is also included, providing helpful information about the game and its mechanics.
