Understanding the Metamask and Web3 Ecosystem
As a decentralized application developer (DAPP), you are probably familiar with the concept of blockchain and smart contracts. However, your DAPP’s positioning on a new platform can be a scary task, especially when it comes to interacting with browser extensions and other web -based features.
In this article, we will delve into two specific scenarios: DAPP deploying on a local machine (using window.ehteum) and we will implement the same DAPP in the AWS cloud (which is not directly available in the cloud window). We will also study what is happening behind the scenes when we interact with browser extensions.
Local implementation on windows using window.ehtereum
When you unfold your DAPP locally, the goal is to create an independent environment that can work without external dependencies. However, there is not much documentation at the moment on how to use window.ehtereum and it seems not directly accessible outside the local machine.
The code fragment you provided:
`JavaScript
// metamask: in a cloud window.EhteumundeFined, in a local window.
`
It seems to show a problem with compatibility. When you start your DAPP locally, the window object contains no property or method ‘ehthereum’, suggesting that there may be some asynchronous loading mechanism.
Possible explanation: asynchronous loading
When you have your DAPP, the Ethereum Blockchain and Ethers.js library (used by metamask) is not yet fully compatible with each other. This can lead to a situation where the object window.ehtereum object, but its methods or properties do not work as expected.
Alternatively, your local configuration may not have access to the same network and IP addresses that when you are implementing AWS Cloud, which can cause problems with compatibility with browser extension.
Implementation at AWS Cloud
When you deploy your DAPP at AWS Cloud, you can use Ethers.js, a popular library for interaction with Ethereum Blockchain. To release your DAPP at AWS Cloud, follow these steps:
- Set the Ethereum portfolio (eg metamask) and create a new project.
- Install the
euteres.jslibrary and import -a to your application code using:
`JavaScript
Import {Euters} by “euters”;
`
- Initialize Euteres.js with information about the Ethereum Machine Network:
`JavaScript
CONST PROVIDER = new euters.providers.jsonrpcprovider (‘
`
- Implant your DAPP using a tool like Truffle or Hardhat that will deal with the implementation process and create a new blockchain account.
After entering AWS Cloud, you can connect your navigator extension without problems:
`JavaScript
// metamask: in a cloud window.EhteumundeFined, in a local window.
`
Conclusion
In conclusion, the implementation of your DAPP at AWS Cloud and the interaction with browser extensions requires careful consideration of compatibility problems between different platforms. Understanding what is happening behind the scenes and eliminates possible problems, you can ensure that your application works smoothly and effectively.
If you are developing DAPP for a new platform, it is essential to explore the specific requirements and limitations of each environment to avoid common traps and ensure a perfect user experience.
