Ethereum Push Notification Service

epns.io

Push (previously EPNS) is a decentralized and blockchain-agnostic communication protocol for the entire Web3 world that aims to provide users with notifications for on-chain or off-chain activity. Push allows Web3 actors (users, dapps, service providers) to create notifications that can be based on any off-chain or on-chain logic that can be triggered via smart contract, backend, or dApps. These come from an open communication network (push nodes) and are tied to wallet addresses, allowing any crypto wallet, frontend, or infra service to display it to Web3 users.
