Push is the communication protocol of web3. Push protocol enables cross-chain notifications and messaging for dapps, wallets, and services tied to wallet addresses in an open, gasless, and platform-agnostic fashion. The open communication layer allows any crypto wallet / frontend to tap into the network and get the communication across.
Push is live on Ethereum mainnet, Goerli testnet, Polygon mainnet, and Polygon Mumbai testnet.
