Sponsor Bounties

Bounty: $1,000.
Description: Develop a dice-based poker game in which each player has five dice instead of cards. Players place bets with tokens, roll their dice, adjust their bets, reroll selected dice once, and then determine the winner. The game follows poker-like rules (e.g., four of a kind, straight, etc.) and uses API3’s QRNG to determine the winner.
Requirements:
•The game should be a progressive web app with an integrated custodial wallet for depositing tokens. This serves as a proof-of-concept for serious web3 games with a user-friendly UX on L2. Utilize Moon for this purpose.
•Use QPI3’s QRNG to determine the winner.
•Abstract reference: The Witcher dice poker
Bounty: $1,000.
Description: When you activate the savings feature, the wallet creates a separate savings contract. Whenever you send tokens from the wallet, swap, purchase NFTs, or perform other transactions, the wallet rounds up the dollar amount and sends the change to your savings. For example, if you swap for $47.83, the wallet rounds it up to $50 and sends the $2.17 difference to your savings.
Requirements:
•The basic version is simply a savings accumulation that can be withdrawn after a period, like a month. Each week, the wallet generates an NFT reflecting your accumulated savings.
•The advanced version involves partnerships with liquid staking, exchanges, etc., enabling the tokens in your savings to be automatically staked in pools and start generating passive income immediately.

Bounty: $1,000
1 winner: $1,000
Description: Add unpredictable dynamics to your application with random numbers by using API3 QRNG in your smart contract.
Project ideas:
•Randomised Airdrops
•Loot boxes
•Randomised NFT Mints
•Light strategy games

Bounty: $1,000
2 winners: $500 each
Description: Hackers are to build a dApp template with a real-world use-case that will be published to the Forward Marketplace for easy understanding, customization, and deployment.
Challenge requirements:
•Participants must sign up for Forward.
•The expectation is a full-stack dApp with guidance/notes for the deploying user, proper labels, and a use case that solves a real-world problem.
•Participants must stick to the provided ideas. If they want to build their own idea, they should get approval for this from Forward via Encode beforehand
Project Ideas:
•Event Ticketing: dApp to control the issuing and verification of event tickets.
•Crowdfunding: dApp allowing investments for entrepreneurs.
•NFT or Token Airdrops: dApp controlling airdrops for NFTs and Tokens.
•Dead Man's Switch: dApp requiring timely interaction to prevent a specific action.
•P2P Carpooling: dApp to facilitate vehicle sharing.
•Unique Fun Game: Open for suggestions.
•Real-World Assets Tokenization: dApp related to RWA or DeFi of RWA.
•NFT or Token Marketplace: dApp to facilitate the sale of NFTs or Tokens.

Bounty: $1,700 and $24,000 in grants within Liteflow’s startup program.
3 Winners: $1,000, $500, and $200. Additionally, all winners can receive a grant:
6 months free usage of Liteflow.
1 hour of advisory call per month.
Access to NFTVerse.
Description: This challenge demonstrates the ease of deploying a marketplace on LightLink as well as creating NFTs. Liteflow will focus primarily on the most innovative business models, ensuring winners can integrate into our startup program post-hackathon.
Challenge requirements:
•Utilize Liteflow products, tools, and templates for easy deployment.
•Define and implement an innovative business model for the marketplace: go beyond percentage-based model (be creative, create custom plugin, use webhook/service, etc.)
•Projects that push the customization of the platform or integrate with other challenges/projects will receive extra attention.
•[Optional] Customize the marketplace's look, feel, layout, flow, and experience.
•[Optional] Integrate with other hackathon projects for added benefits.

Bounty: $1,000.
1 Winner: $1,000.
Description: Develop an AI-powered app or tool, such as a trading bot, block explorer, or intent solver, using Moon Wallet & Moon AI on LightLink.
Challenge Requirements: Use Moon Wallet & Moon AI on LightLink.

Bounty: $1,000.
Additional Requirement: The game should be a valuable addition to the Yesports product suite, including the NFT No Loss Lottery.
Ideas:
A poker dApp utilizing QRNG to establish a virtual deck of cards, ensuring random and unaltered order throughout the game. Post-game, players can verify the deck's randomness. The dApp should also incorporate Enterprise Mode for transaction-free gameplay.

Bounty: $1,000.
Description: Create a game similar to "Cards Against Humanity," where Pyth’s Entropy (RNG) selects a question card, and Entropy also deals cards to players. The twist is that players can mint NFTs of their amusing card combinations onto their digital wallets to share on social media, with friends, etc. The game is primarily text-based, making it a relatively simple task.
Challenge requirements:
•Use Liteflow for minting card combinations.
•Implement Pyth’s Entropy (RNG) for card selection and dealing.
•Optionally, incorporate features such as adding new cards through community voting, spectating games, and donating to the most entertaining players.
Abstract reference: Cards Against Humanity

Deployment pool prize sponsored by LightLink and Blockscout: $5,000 for deployment on Testnet and completing a task from Blockscout.
Blockscout provides a comprehensive, easy-to-use interface for users to view, confirm, inspect and interact on EVM (Ethereum Virtual Machine) blockchains. Blockscout currently supports a wide range of projects and chains. While there are several explores available to blockchain projects, most are closed systems (ie Etherscan, Etherchain) which are not independently verifiable. Blockscout provides a much needed open-source alternative. As the multi-chain paradigm continues to take hold in both private and public settings, transparent tools are needed to analyze and validate transactions.
Requirements:
- Deploy a project on LightLink Testnet aligned with the hackathon and challenge requirements.
- Blockscout MyAccount Interaction: Set up 'MyAccount' on the Phoenix Blockscout instance and perform one or several actions within MyAccount. These can include adding an item to a watchlist, adding private tags, possibly verifying ownership of a smart contract address, or submitting public tags.

Bounty: $5,000
5 winners: $1,000 each
Description: Hackers are to build a simple season rewards functionality which enables gamers to complete quests to earn XP tokens, level up based on XP earned (there should be multiple levels).
Challenge Requirements:
•Include XP token
•Quests
•Multiple levels
•Token burn mechanism
•Entertaining ways to gain XP token
•Gamification
Bonus points:
