Error in Metamask Integration: “Web3” word mismatch

As a Web3 developer, you are not alone in dealing with problems with solving the “Web3” word mismatch. This error usually occurs using Metamask browser extension to connect your Ethereum purse into web applications.

Error message “could not find the word” Web3 “” or “Did you mean” Web3 “?” It suggests that Metamk is unable to determine whether to use “Web3or" Web3 "as a Web3, a popular JavaScript library service provider used to interact with Ethereum Blockchain.

Causes of question

There are several reasons why this could happen:

1
The URL Misclosure of the Service Provider

: Make sure you have properly secured the service provider URL in your Metamk extension settings.

  • Infurl is not set as a default service provider

    : If you use the Infura Web3 API, make sure it is set as your default service provider by clicking on the "Settings" icon and selecting "Default Service Provider".

3
Infurl is not properly configured Web3.Js : Make sure the infura web3 API is properly configured to use the Web3.For.

Solution of the question

To resolve this issue, follow these steps:

  • Check your service provider URL : Check that you have provided the correct infurl in the Metamask extension settings.

  • Check the Default Service Provider Selection : Make sure the Infura Web3 API is selected as your default service provider by clicking on the "Settings" icon and selecting the "default service provider".

3
Update service provider configuration Web3.JS : If you are using infura, make sure the service provider URL is properly configured to use Web3.For. This can be done by updating the variable "Infurl" in its code:

JavaScript

Const Web3 = New Web3 (New Web3.Providers.httpprovider (‘

`

Replace your_project_id' with your actual infura project ID.

  • Try again : After making these changes, try connecting to the Ethereum network and check that as a service provider you are using web3:

`JavaScript

Console.log (Web3.eth.Net === ‘
