Dapp Notifications

Sending.Network (SDN) provides a universal inbox to receive messages from dapps and wallets. This way, users can receive time-sensitive dapp messages, like an NFT floor price drop or an imminent liquidation in a lending protocol position. There would be tremendous user scenarios for such communication. A decentralized exchange can notify users when the desired gas price is reached, or an NFT marketplace sends out heads-up notifications of NFT auctions, saving users’ effort from regularly checking.
Below we provide a specific use case describing how the user can receive a decentralized exchange (DEX) notification inside the wallet app when the desired gas price is reached.
