Building a cross-chain product? Meet Chain Signatures: the latest programmable MPC technology that enables cross-chain protocols to support every chain (even non-smart contract chains), eliminate the risk of bridging, and unify user experience. Demonstrate a creative use case of the Chain Signatures API, such as account aggregation: a single NEAR account that can sign transactions on any EVM network, and even Bitcoin. Get creative and explore the beginnings of chain abstraction, where users don’t have to think about which chain they are on! *Your deployment should be on the NEAR testnet and may incorporate any ECDSA-based blockchain of your choice. Claim your testnet account and tokens at the NEAR booth.

Qualifications

- Your submission must be deployed on the NEAR testnet. - Your submission may incorporate any ECDSA-based blockchain(s) of your choice. - Your submission must NOT be a simple fork of an existing example with minimal changes. - Your submission should include a basic readme file explaining the scope of the project - Your submission should demonstrate a creative chain signatures API use case. For example: 1) Account aggregation: aggregate accounts and transactions across several chains while only signing with NEAR. 2) Pay in $NEAR, validate price by oracle in a NEAR contract, and have this contract MPC sign and transfer an asset, fungible or non-fungible, on another chain. 3) Protect accounts on other chains with a NEAR smart contract that can only call an MPC to sign when certain conditions are met. You will be judged by: - Creativity and originality of the idea. - Quality and completeness of the product. - BONUS: Feedback on the chain signatures technology and developer experience to help improve it before mainnet launch (we will read every word!)

Build your project that expands and benefits the Avail ecosystem, or uses Avail DA in a meaningful manner.

Qualifications

Project Ideas for hackers include: 1. Use Madara/Rollkit/RISC Zero/SP1 to build a custom application-specific rollup (e.g. an order-book exchange rollup) -> Must use Avail DA as the data availability layer. 2. Build a Liquid Staking Protocol for Avail - either directly on the node, a substrate pallet, or on Ethereum powered by a bridge, or via any other means. 3. Add p2p feature to Avail's web LC, that allows it to be connected to the light client p2p network. 4. Build a JS wrapper/JS-equivalent, Bridge API (currently implemented in Rust). 5. P2P Address Book: Create a webapp which uses the Avail LC in crawl mode to log addresses and timestamps of peers as they join a network. - **Bonus points**: The p2p network could use websocket to establish connections with other LCs without needing a public multiaddress 6. IoT WebApp: Build an IoT web app of your choice on Raspberry Pi/BeagleBone/any suitable RTOS device using the Avail Light Client connected to a public Avail network like Goldberg. These are ideas to help you give an idea of what to build with Avail in this hackathon. We're open to seeing other innovative ideas from you.

With the Dencun upgrade on Ethereum, data submission (blobs) costs by L2s to Ethereum Mainnet are expected to reduce compared to calldata. Build a visualizer or calculator to compare and estimate the cost reduction between calldata (pre-EIP4844) vs blob (post-EIP4844) submissions. Teams must estimate and visualize the cost change for major L2s (Optimism, Arbitrum, Polygon zkEVM, Starknet, zkSync, etc.)

Qualifications

Criteria for evaluation will be based on: - Number of L2s whose cost is being visualized - Intuitive design and presentation of the visualizer. - Use of live data would be given extra points over static data. - BONUS: Simulation of congestion and the comparison of congestion handling and costs of calldata vs blobs in that scenario would also get extra points.

This bounty is reserved for the most creative implementation utilizing the OApp standard. We're looking for applications that not only demonstrate technical proficiency but also push the boundaries of what's possible in omnichain development.

Qualifications

To be eligible for the Best OApp Implementation ($2,500 USD) at ETHGlobal London, participants must meet the following specific criteria: Inheritance of OApp.sol Contract: The core requirement is that the developer's application must inherit the OApp.sol (or alternatively the OAppSender or OAppReceiver) contract standard. This standard is crucial for enabling the desired level of interoperability and message passing between blockchains. Extension of the OApp.sol Contract: Merely inheriting the OApp.sol contract is not enough. The application must extend its functionality. This means that developers should build upon the basic framework provided by the OApp.sol contract to introduce new features, optimizations, or use-cases for omnichain interoperability.

This bounty is awarded for the most outstanding implementation of the Omnichain Fungible Token (OFT) standard. We seek applications that showcase exceptional use of LayerZero's Omnichain ERC20 token standard to create cross-chain solutions.

Qualifications

To qualify for the Best OFT Implementation bounty, participants must adhere to the following specific criteria: Inherit the OFT.sol or OFTAdapter.sol Contract Standard: The primary requirement is for the developer's application to inherit either the OFT.sol or OFTAdapter.sol contract standard. This inheritance is crucial as it forms the foundation upon which the developer will build their application. Extend the Inherited Contract: It's not sufficient to simply inherit the OFT.sol or OFTAdapter.sol contract; the developer must also extend it. This means adding new functionalities, features, or optimizations to the base contract. The extension should demonstrate innovation and an advanced understanding of the OFT standard. Implementation of Cross-Chain Functionality: Given that OFT is focused on omnichain token solutions, the application should effectively implement cross-chain functionality. This means that it should enable the seamless movement and interaction of tokens across different blockchain networks.
