OpinionSwap2,500 LINKBuild 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
- Each project must use Chainlink CCIP 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 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.

WeatherBetter$2,500Inspiration: Imagine the power of AA wallets with their smart contract execution functionalities. Now, pair that with Unlimit's capability to onramp into any cryptocurrency from any fiat currency or vice versa for offramps. An example could be a dapp where users utilize Unlimit's onramps to acquire a specific token, and upon receipt in their AA wallet, a predefined logic they created and manage initiates an NFT purchase. But that's just one example. The real magic lies in bridging the DeFi/Web3 Gaming/NFT world with the traditional banking/fiat realm through your innovative, “non-custodial dapp”. The possibilities are endless.
Develop an app that seamlessly integrates Unlimit’s on/off ramps with combinations of the following: -Account Abstraction Wallets (AA wallets) -Dapps from the DeFi/NFT/Gaming/Web3 ecosystem -Integration with web2 technologies to expand utility and accessibility

Zero-knowledge continues to dominate Ethereum narratives and Polygon is at the forefront of these efforts. In this bounty, we are inviting builders to incorporate ZK in their projects in new and innovative ways. We have two ZK tracks for your consideration.
An innovative project that uses zero-knowledge to preserve user privacy or extend the use of existing zero-knowledge applications in blockchain, such as the zkEVM. This is an open bounty where we are looking for exciting ZK builders who want to build on top of Polygon using any ZK DSL of their choice. Successful projects should look like a clear demonstrable use of zero-knowledge primitives. You have to write your own circuits and demonstrate an innovative use of an existing ZK primitive or build one of your own. If you’re building a privacy app, then we would like to see you incorporate a minimally invasive user experience. User experience lies at the heart of a successful ZK implementation, we are excited to see how you can build a delightful experience for your privacy apps or deliver a great performance improvement using ZK in a way that solves different problems. You can build a Privacy App with an interface or have no UI at all.
