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.

Overview
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.
Receiving DEX gas price notification from wallet
- 1.DEX
- 2.Wallet app
- 3.User
- 4.Sending.Network protocol
- 1.The DEX has integrated the Sending.Network protocol.
- 2.The wallet app has integrated the Sending.Network protocol.
- 1.The use case begins when a user authenticates in the DEX.
- 2.The user sets a target gas price as a notification condition.
- 3.When the gas price is met, DEX calls Sending.Network service message interface to send out a notification message to the user's wallet address.
- 4.The wallet receives the DEX message.
- 5.The wallet displays the message.
- 6.The use case ends successfully.

Flow Chart
The user successfully receives the DEX gas price notification and the message has been saved in the wallet app.
