Ethereum: InvalidResponseError: Returned error: unknown account
I can help you. Here is a step -by -Step guide and an article example:
Ethereum: InvalidresponseError: Returned Error: Unknown Account
Ethereum blockchain is a decentralized, public and safe platform for the construction platform for intellectual contracts and decentralized programs (DApps). You must have ethereum wallet and a valid private key to communicate with Ethereum network.
In this guide, we will use the Web3.JS Library to interact with Ethereum Blockchain. We will also use the solids compiler to assemble our code of intellectual contract into the ethereum byte code.
Example Code
Below is an example of how you can save your account private key in your local system and then Sign the Operation Using the Account:
`JavaScript
// Imports Required Libraries
Const Web3 = Require ('Web3');
Const SolidationCompiler = Require ('SOLC');
// Set the Web3 Copy along with Ethereum Provider (EG Infura, etc.)
Const providerrl = '
Const Web3 = New Web3 (New Web3.Providers.httprovider (Providence));
// compile solidis bytecode for your intellectual contract
SolidyCompiler.compile ('Road/To/Your/SmartContract.Sol', (ERR, BaityTecode) => {
If (ERR) {
Console.error (ERR);
to return;
}
// Get Ethereum Account Private Key from the Contract
Const Contractaddress = '0x ...'; // change the address of your intellectual contract
Constvkey = Web3.eth.GetTransactionrecypt (Contractaddress) .transaction.praVatekey;
// Sign Operation Using a Private Key
Const Signature = Web3.eth.SignTransaction ({{{{{{{{{{{{{{{{{{{{
From: 0x ..., // Change Your Ethereum Account Public Key
Date: Byte Code,
Gaslimit: 20000,
Nonce: 1,
Privatekey: Privatekey
}, (error, txhash) => {{{{{{
If (ERR) {
Console.error (ERR);
to return;
}
console.log (txhash); // this should print the Operation Bag
});
});
Error Explanation
“Invalidresponserror: Returned Error: Unknown Account” Error Usually occurs when trying to sign an operation using Ethereum Private key that does not match any known public key. This can happen if the private key is not correctly stored or if it is not used with a valid public key.
In your case, you mentioned to store the account private key in your local system and sign an operation with that key. However, you did not give an example of how to safely hold a private key. To correct this Error, Make Sure:
- Safely Protect the Private Key (EG Using Hardware Wallet or Safe Password).
- Check that the private key corresfonds to any known public key.
- Use the correct parameter from “from” to sign the operations.
If you still have problems, provide more information about your ethereum account and the intellectual contract code and I will do my best to help you continue.
Additional tips
- Always use a Secure Password or Hardware Wallet to Store Private Keys.
- Remember to check the web3.js documentation for any updates or changes in the Library Behavior.
- Use a reliable ethereum provider (such as infura) to make sure your account and contract addresses are accurate.
I hope this will help! If you have more questions or concerns, do not hesitate to ask.
