Ethereum: Cannot find a value for the configuration variable ‘INFURA_API_KEY’
Ethereum Hardhat Project Configuration Issue With Infura Api Key
As you configure a new NPX Hardhat project, you meet an error wen try to import Envfile. This problem is relatively comomon and can be resoled by understanding how to correctly configure.
The error: HH1201 cannot any walue the configuration variable 'infura_api_key'
The HH1201 error indicates that the configuration variableinfura_api_keycannot in your code. This error generally occurs the code to the access to the environment variable, but it is not defined.
** How to sol the problem: Read your fire.
To solve that problem, you own is yours. Here are soohes to help you solve the Problem:
Step 1: Create a new file .
Create a new file named. Playing theroot of your project. This fire will all contain all your environmental variables.
`bash
touch.
'
Step 2: Add an infura key to.
Add the next line to ‘
`bash
Infura_api_key = youur_api_api_heere
'
Replac you_infura_api_key 'by your your API Infura real key.
For example, if you can a a private ky an environment variable for your infura API key, you candd itlika this like that:
bash
Infura_api_key = your_private_heere
'
Step 3: Update your Hardhat configuration
To use the Infura API in your Hardhat project, yu must update the configration variables. More specifical, you must define the variableinfura_api_key.
You can do by adding an infuraconfig.json file to the root of your project this following content:
`JSON
{
"key": "",
"secret": ""
}
'
If you are a private kae an environment variable for your infura API key, update theinfura_api_key
Step 4: Update your Hardhat project configuration

`Javascript
Export module = {
// ... Other configurations ...
Defaultconfig: {
// ... Other configurations ...
Infura: {
Key: process.env.fura_api_key,
Secret: Process.Ev.infura_secret
}
},
};
'
Step 5: Run yourour Hardhat project
Finally, run your Hardhat project use
bash
NPX Hardhat
'
The variableinfura_api_keys the correctly defined for your infura API ky.
Example of use cases
Here is an examplee to to to to drink this configration in a simple deployment of an intelligent contractor:
Javascript
Const Ethers = require ('eters');
// Hardhat configurations
Export module = {
// ... Other configurations ...
Defaultconfig: {
// ... Other configurations ...
Infura: {
Key: Process.enf.infura_api_key,
Secret: Process.Ev.infura_secret
}
},
};
// Deployment of smartcats
Const Deployer = New Ethers.Deployer ('0x …'); // replaced with your deployed contractres
hand asynchronous function () {
to try {
Constaddress = Await Depluyer.address ();
Console.log (contractdress);
} Catch (error) {
Console.error (error);
}
}
main();
`’
