✍️ Best Use of Chain Signatures: Cross-Chain Apps Without Bridges ⸺ $5,000

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.

Qualification Requirements

- 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!)
