NEAR Use Case

These contents have been prepared using online resources. Patika.dev’s own contents are currently under preparation.

Guest Book is a smart contract build on top of NEAR Protocol. It is a simple smart contract that allows you to add a message and donation (optional). It is built by using AssemblyScript on the contract side, and React on the frontend.

Let’s take a look at this smart contract and see how it is very similar compared to any other application that is built on Web 2.0.

• Click this link to go to the dApp near-examples.github.io/guest-book/

• Here you need to login with your wallet to be able to use this dApp

• Click next to continue

• Click Connect to continue

• After you logged in, you will see your account ID.
• It means you successfully logged in to the dApp!
• Now, try to type your first message that will be stored in the blockchain.
• Click the button “Sign”

• You will see your message appear at the bottom of the list with many other messages from different accounts.
• Congrats! You have just interacted with the blockchain!
• OPTIONAL: If you are wondering about the “Donation” part, don’t be shy and try to attach some amount of NEAR and see what happens with your next message.
