Problem Statement
N-hub is a multi-chain attestation dApp with notification capabilities. Here is a video explanation: https://youtu.be/QQJOwe92xkUWe aim to simplify and standardize the issuance and verification of attestations across different blockchains, eliminating the need to transfer funds between networks. Our solution offers unprecedented interoperability, enhancing accessibility and efficiency in the blockchain ecosystem.
Solution
This dApp enables @EthereumAttestationService schema and attestations issuance on multi-chains thanks to @Chainlink Cross-Chain Interoperability Protocol (CCIP).A (targeted) user receives @PushProtocol notifications on @Metamask Push Snap, which is triggered every time an attestation is issued, by @EAS Schema Resolver thus eliminating the need for a backend to receive notifications via hooks and not by listening to on-chain events.We also used @WalletConnect Modal SDK to manage the identity and connect users to the dApp.
