Chainlink CCIP Track
Total amount Prize:
$2,000
Best 2 projects using Chainlink CCIP - $1,000 each
Bounty Description
Build something awesome using Chainlink CCIP! The Chainlink Cross-Chain Interoperability Protocol (CCIP) provides a single simple interface through which dApps and web3 entrepreneurs can securely meet all their cross-chain needs, including token transfers and arbitrary messaging.
Possible use cases:
- Cross-chain DeFi app with liquidity across multiple chains
- Cross Chain DeFi yield aggregator
- Token bridge powered by CCIP
- Multihop CCIP Router. You want to send cross-chain message from blockchain A to blockchain B without worrying if the lane between them exists
Requirements:
- Each project must use Chainlink CCIP in some form to make a state change on a blockchain, otherwise it will not be eligible. This means that a front end simply reading from Chainlink Data Feeds doesn't count. Using Chainlink CCIP inside your smart contracts is required, though you are encouraged to utilize Chainlink Data Feeds, Chainlink Data Streams, Chainlink VRF, and Chainlink Proof of Reserve as well.
- While all project submissions are evaluated holistically, there will be bonus points given to projects that use Chainlink CCIP together with other Chainlink services in a meaningful way.
- Please let us know how you use Chainlink in the project description.
- It must be possible for the judges to find the Chainlink use in your code. Only the intention to use is not valid.

- Verifiable AI: Can use Functions to verify the output of an AI LLM, & get an attestation that the output is correct & what the LLM actually outputted
Requirements:
- Each project must use Chainlink in some form to make a state change on a blockchain, otherwise it will not be eligible. This means that a front end simply reading from Chainlink Data Feeds doesn't count. Using Chainlink inside your smart contracts is required.
- While all project submissions are evaluated holistically, there will be bonus points given to projects that use Chainlink services together in a meaningful way.
- Please let us know how you use Chainlink in the project description.
- It must be possible for the judges to find the Chainlink use in your code. Only the intention to use is not valid.
Judging criteria for all tracks:
- UI/UX/DX - How useful is your application? Is it visually appealing?
- Blockchain technology application - How valuable this project is for decentralization and adoption of Blockchain and Web3
- Wow Factor - Anything not covered above! This is if you blow us away in some other way.

About the workshop
Simeon Kotashki - Lead Integration Engineer of Neon EVM
Ethereum dApps Deployed & Run on Solana
This workshop will provide invaluable insights on how to integrate your EVM applications within the Solana network. After this workshop you will be able to read any data on Solana natively from your Solidity smart contracts deployed on NeonEVM.
Prizes
- 20 Ledger devices will be distributed among the top 4 teams.
Requirements (for a project to win, it should have at least one of three conditions):
- Best project implementing ledger hardware device integration.
- Best project implementing self-custody methods.
- Best project implementing clear signed transactions for users.
