Install and use plug-in wallet 1. Open the app store of the Google browser and search for Bystore

two。 Then click add to Chrome to add to our:

3. Use the google plug-in wallet

If you are using a test network, you can go to the test network faucet to get BTM. Test net faucet: http://test.blockmeta.com/faucet.php

Set up Dapp demo

Dapp demo is a savings contract based on Biyuan, which allows you to lock up your assets and return them at maturity with a certain amount of interest. The suitable scenario for this dapp is the dividend dividend, which is automatically locked through the intelligent contract, and the maturing assets are automatically unlocked. So personally, I am very optimistic about this dapp application scenario.

Project source address: https://github.com/Bytom/Bytom-Dapp-Demo

Build the dapp according to the readme.md file in the source code, and then we can see the dapp application when we open http://127.0.0.1:8080 locally. Then we click on our account as shown below:

Click saving, and what we see is the savings assets interface, where users can set the amount of assets and save assets.

The following figure is our earnings page, we can see the income of our savings, if it is due, we can propose our own income.

Transfer transaction interface

The following figure shows the API API for sending transactions. For more information on the API, please see https://github.com/Bytom/Bystore/wiki/API-reference. There are other API interfaces in this document. Listen to the event interface bytom.request (eventName, options).

Back-end server interface

Because of the UTXO model adopted by the original chain, the model has no state. However, in the process of developing dapp, you need to associate the user's address. Therefore, the back-end server mainly encapsulates a layer of similar account model to facilitate dapp to interact with the chain. Developers who develop dapp can build a modified project as a server to interact with the chain, and build their own readme for the reference project.

Combing the Dapp development process

Through the above series of steps, we have a general idea of the process of developing dapp based on the original chain. The process summary is as follows:

Step1: download and install the Chrome plug-in wallet if you don't need to skip this step on your dapp. Step2: if you need to build your own BlockCenter backend server, refer to the project instructions to install it. If you don't want to build it, just use the official service and call it remotely. Step3: develop smart contracts and compile. Then configure the compiled contract parameters in the dapp configuration file, as shown in the following figure: (the full red part is the test net contract configuration parameters)

Step4: call the Chrome plug-in wallet. Thank you for reading, the above is the content of "how to call Bytom Chrome plug-in wallet to develop Dapp".
