Each project must use Chainlink in some form to make a state change on a blockchain, otherwise it will not be eligible for the Chainlink core prizes. This means that a front end simply reading from Chainlink data feeds doesn't count. Using one of Chainlink Data Feeds, Chainlink Data Streams, Chainlink VRF, Chainlink Proof of Reserves, Chainlink Automation, Chainlink Functions or Chainlink CCIP inside your smart contracts is required.

For sponsor prizes, you do not have to use Chainlink - but to make your project as best as it can be using the materials here, it is recommended you do!

Note that past onchain hackathon projects will not be accepted as valid submissions. The only exception to this rule is if you and your team have built an existing project without any onchain components. These can be added upon and submitted in a valid manner.

While all project submissions are evaluated holistically, there will be bonus points given for multiple Chainlink services used in a meaningful way within a project. For example, two additional points are awarded for using two services, while three additional points are awarded for using three different services—and so on.

Financial Services Track

Expand the world of onchain finance by building the next DeFi primitive, an application that connects DeFi with TradFi, or a solution that makes existing financial services more accessible. Chainlink Data Streams, Data Feeds, Functions, and CCIP can help you level up the tokenized asset economy. Use cases include:

• Fractionalize tokenized assets and make high-value ticket items easily accessible across the DeFi landscape.
• Develop a system that enables banks and asset managers to easily tokenize any asset and make it available on any blockchain.
• Synchronize offchain ledgers of record and onchain contracts to create a unified Golde Record for banks, protocols, and end users.

Cross-Chain Solutions Track

Take your DeFi, Gaming or AI dApp and enhance its potential user base and liquidity by making it a CCIP enabled cross-chain application.

Use cases:

• Cross-chain DeFi app with liquidity across multiple chains
• Cross-Chain game where players on chain A can play players on chain B
• Cross chain liquid staking protocol

Artificial Intelligence Track

Build a dApp that showcases how you can combine the superpowers of AI and blockchain. Chainlink Functions is your gateway to connecting a smart contract to AI LLMs and services via API calls.

Use cases include:

• Enhancing smart contracts by leveraging AI to run computation, statistical analysis, heuristics, pattern matching, or other forms of offchain computation, then returning the result back onchain to the smart contract.
• Using blockchains and smart contracts to provide guardrails for offchain AI systems.
• Use offchain AI as part of a Web3 game to act as a non-player character.

Gaming and Consumer Apps Track

Create the next generation of Web3 games or blockchain-powered consumer applications—from social to B2B, the opportunities are endless.

Use Cases:

• Use VRF to build the next big Web3 game.
• Use Functions to connect to offchain systems and services as part of a consumer app (e.g., send an email or SMS with Twilio.)
• Build a SocialFi application using Functions to connect to offchain systems or Web2 social data.
• Use Functions to build a new Lens Open Action or Farcaster frame.

MOONBEAM

Create a Gasless Experience with Moonbeam's Call Permit Precompile

Using Moonbeam’s Call Permit Precompile is an easy way to enable gasless transactions for users of your dApp. By utilizing the call permit precompile, you can have users sign a message to authorize any EVM Call. With Moonbeam’s Call Permit precompile, the end user signs an EIP-712 type message, and importantly, the signed message can be used to dispatch any arbitrary EVM call (it’s not limited to token approvals). Then, anyone can submit the signed message to the Call Permit Precompile on behalf of the user (presumably, you, as the dApp developer would submit the transaction and cover the corresponding gas costs).

The scope of this bounty is to use Moonbeam’s Call Permit precompile to improve the end user experience in your dApp. There are numerous use cases that are particularly well-suited for gasless transactions, such as games, bridges, cross-chain swaps, and much more. You are free to incorporate this bounty challenge into a new dApp you’re building for the hackathon, your own existing dApp, or you may fork any existing open-source dApp and enhance with the Call Permit Precompile. If you are forking an existing open-source dApp and enhancing it with gasless transactions via the Call Permit precompile, you will be judged only on the improvements that you made (e.g. you will not be judged on the existing UI of the dApp that you forked).

Submissions will be judged principally on the following four categories:

Technical Excellence - High scoring submissions may demonstrate impressive technical skill and quality of implementation. Teams tackling challenging problems, even if the resulting solution is not fully baked will rank higher.

User Experience and Design - Can you abstract away complex cross-chain concepts into a simple and intuitive experience for the end user? High scoring projects will be thoughtfully designed to provide an enjoyable experience for Web3 beginners and veterans alike.

Value Proposition - Are you making something users want? The highest scoring submissions will have the potential for significant market adoption due to their clear value proposition.

Creativity - Unique projects or new and creative approaches to existing ones will be among the highest scoring submissions. (Copy / paste deployments from other chains will rank lower in this category).

Requirements: The submission should include a deployment of smart contract code to Moonbase Alpha or Moonbeam and should use the call permit precompile.

Batch Transactions with Moonbeam

Use Moonbeam’s Batch.sol to batch transactions together. Moonbeam’s Batch.sol Precompile allows you to easily batch together multiple transactions into a single call. The Batch Precompile is a solidity interface that can intelligently batch transactions together based on your use-case. You can choose from the following different methods of the Batch Precompile:

BatchAll - requires all of the subcalls to succeed, otherwise the batched transaction fails.

BatchSomeUntilFailure - keep trying to execute subcalls until one fails, then stop. Any subcalls before the failure remain successful and are not reverted.

BatchSome - try to execute every single subcall regardless of failures. If a subcall fails, it will continue on to execute the next one.

As you can see, you can cleverly tailor the batch precompile to your specific use-case. As an example, if you want to combine both the approval and swap transactions for a DEX, it would make the most sense to use Batch All, because the transactions are dependent upon each other. The swap transaction should only be attempted if the approval is successful, and the approval should only be granted if we know that the swap is going to be successful. If either is going to fail, then the entire batch transaction should fail as well.

You can use the Batch precompile in any manner that you see fit. Ideal submissions will use the Batch precompile to enhance the end user experience of their dApp. Submissions can optionally specify in the ReadMe the method(s) of the Batch Precompile they use and why the method(s) was chosen in particular. You are free to incorporate this bounty challenge into a new dApp you’re building for the hackathon, your own existing dApp, or you may fork any existing open-source dApp and enhance with the Batch Precompile. If you are forking an existing open-source dApp and enhancing it with the Batch Precompile, you will be judged only on the improvements that you made (e.g. you will not be judged on the existing UI of the dApp that you forked).

Submissions will be judged principally on the following four categories:

Technical Excellence - High scoring submissions may demonstrate impressive technical skill and quality of implementation. Teams tackling challenging problems, even if the resulting solution is not fully baked will rank higher.

User Experience and Design - Can you abstract away complex cross-chain concepts into a simple and intuitive experience for the end user? High scoring projects will be thoughtfully designed to provide an enjoyable experience for Web3 beginners and veterans alike.

Value Proposition - Are you making something users want? The highest scoring submissions will have the potential for significant market adoption due to their clear value proposition.

Creativity - Unique projects or new and creative approaches to existing ones will be among the highest scoring submissions. (Copy / paste deployments from other chains will rank lower in this category).

The submission should include a deployment of smart contract code to Moonbase Alpha or Moonbeam and should use the batch precompile.
