The communication protocol of web3 is called the Push Protocol, formerly known as the Ethereum Push Notification Service or EPNS. Push protocol provides open, gasless, and platform independent cross-chain alerts and communications for wallets, decentralized applications (dapps), and services linked to wallet addresses. Any cryptocurrency wallet or frontend may connect to the network and communicate via the open communication layer. Push is now the default communication layer for web3 after powering over 17 million decentralized alerts to more than 60,000 members since its introduction in January 2022.
