Hackathon Victory Showcase

Grand Prize ($50,000)

The Future of France

The Grand Prize for Block Magic: A Chainlink Hackathon has been awarded to The Future of France, a Web3 learning game built by developer Donald Morton. This project aims to onboard the next generation of Web3 users, with a strong focus on learning key Web3 skills in a secure and engaging manner.

The game leverages a task-based scaffolding method of education, guiding players through seven training levels that cover essential tasks every Web3 user should master. Players start by connecting a wallet to a website at level 1 and advance to making a VRF request and minting an NFT by level 7. 

Chainlink services play a vital role in the development of this game:

  • Chainlink Automation is leveraged to trigger a withdraw function that sends ETH back to the in-game faucet monthly.
  • Chainlink Functions is leveraged to verify that players have completed graduation requirements before minting the graduation gift token and to convert collected tokens into ERC-20 tokens. 
  • Chainlink VRF is leveraged to mint randomized graduation gifts for players who reach level 7. 
  • Chainlink CCIP is leveraged to transfer tokens from Ethereum Sepolia to Arbitrum Sepolia.

Financial Services ($22,500)

First Place: BuckyFinance ($15,000)

Developed by Quang Nguyen, Duc Anh Le, Trần Anh Đức, and Tuan Hoang Le, BuckyFinance is an innovative cross-chain CDP protocol with an AI-powered in-credit system. The protocol utilizes Chainlink CCIP to transfer tokens across blockchains securely. In addition, Chainlink Data Feeds are utilized to obtain accurate and real-time price data, ensuring up-to-date information for collateral valuation. Finally, Chainlink Functions is leveraged to query and calculate credit scores based on AI-powered infrastructure, which tracks a variety of onchain activities and balances.

Second Place: Blockshield ($7,500)

Created by André Rodrigo Meira e Silva, Ramiro Gonzalez, Edson Cavalca Jr., Jether Rodrigues, Miro Leite, Blockshield empowers users to purchase insurance coverage against the risk of default for tokenized assets. To acquire an insured tokenized asset, users exchange the original token for an insured token issued by Blockshield. A transaction fee, paid by the user, is sent to the smart contract vault, which builds a fund to cover any defaults on the original tokenized assets. 

Blockshield leverages the Chainlink platform to ensure a seamless and secure user experience: Chainlink Functions to monitor the original tokenized assets, Chainlink Automation to trigger the smart contract for the insured token on the maturity date, Chainlink Price Feeds to provide accurate market data for the tokenized assets, and Chainlink CCIP to enable secure cross-chain token transfers.

Cross-Chain Solutions ($15,000)

First Place: Chronomancer ($10,000)

Created by Cactoid Cactus and Frost Corealis, Chronomancer is a contract endpoint and bot that provides fast transfers for any token powered by Chainlink CCIP. Leveraging the industry-standard Chainlink CCIP, Chronomancer ensures users can make highly efficient cross-chain transfers with level-5 defense-in-depth security. Chronomancer scans for outgoing CCIP messages on a source chain and provides instant token transfers on the destination chain using two components: a smart contract endpoint and an order-filling bot.

Chronomancer is particularly useful because it addresses the common challenges associated with cross-chain transfers such as speed and efficiency, while still utilizing the security and reliability of CCIP. Instead of a user sending tokens and data to a destination chain smart contract or EOA with CCIP, they are sent to the Chronomancer smart contract endpoint on that chain (once again using CCIP). Offchain bots scan the outgoing CCIP messages and can optimistically complete the transfer immediately on behalf of CCIP, well before the programmatic token transfer is finalized. When the CCIP token transfer comes through, the bot that already completed the transfer gets refunded and earns a small fee for completing the transfer early. In the event that no bots fill the transfer, it will reach the Chronomancer smart contract endpoint and the smart contract will forward it onto the original intended destination.

Second Place: Buckle ($5,000)

Bringhi Leone developed Buckle, a liquidity-based bridge. Buckle enables users to transfer tokens cross-chain with minimal fees and defense-in-depth security provided by Chainlink CCIP. 

The protocol consists of two smart contracts: CrossChainPool and PoolFactory. CrossChainPool pairs pools on different chains, allowing token transfers from chain A to chain B. When a user initiates a transfer, the pool on chain A sends a CCIP message to the pool on chain B, which releases the tokens to the user minus fees. PoolFactory deploys paired pools on different chains with a single transaction using a CCIP message, ensuring seamless integration and setup.

Artificial Intelligence ($15,000)

First Place: Zero Internet ($10,000)

Zero Internet, developed by Godson Ani and Blossom Ohaeri, enables users to interact with AI agents and blockchains offline. It features a data marketplace where users can publish or purchase datasets, which AI agents use to enhance their knowledge base. 

A smart contract securely manages metadata and keys for offchain data in a decentralized database, ensuring reliable data handling for AI applications. Zero Internet leverages Chainlink Functions and Chainlink Automation to monitor and manage offline sessions with AI agents, providing a seamless user experience.

Second Place: BlockTease ($5,000)

BlockTease is a Web3 creator platform that addresses issues in traditional Web2 systems. Created by Vibhav Sharma, Anish Tiwari, and Ketan Kudikyal, BlockTease leverages various Chainlink services to enhance its platform. 

Chainlink Automation powers the auto-renewal subscription features, while Chainlink Functions and Automation help the platform send timely notifications to users. Chainlink Price Feeds ensure accurate and reliable pricing, and Chainlink VRF enables fair and transparent monthly lucky subscriber draws. Additionally, the industry-standard Chainlink CCIP enables secure cross-chain subscriptions for creators, allowing users to subscribe to content across various blockchains.

Gaming & Consumer Apps ($15,000)

First Place: Fury Racing ($10,000)

Fury Racing is an onchain racing game leveraging battle-tested Chainlink services developed by David Phalaris, Pierre ESTRABAUD, Tunde Ogundele, and Jean-S. Lemay. In this car manager racing game, players don’t drive the cars themselves but optimize their attributes to achieve the best times against other players. The game utilizes Chainlink VRF to access cryptographically verified randomness, Chainlink Functions to query APIs directly from smart contracts, and Chainlink Automation to update in-game weather data.

Second Place: zkVampireSurvivors ($5,000)

Kevin Rum developed a time survival game with minimalist gameplay called zkVampireSurvivors. In the game, the customizable character is surrounded by monsters with no escape—the goal is to survive as long as possible. zkVampireSurvivors utilizes Chainlink CCIP to create a leaderboard that can display multichain data and Chainlink VRF to create an in-game lottery mechanism.
