Ethereum: Someone please help me to solve Transaction Revert problem

Ethereum Transaction Restores the Problem and Solution

As a developer Ethereum, you will probably have to face a frustrating issue with the return of the transaction. In this article we examine the problem and offer a solution to solve it.

The transaction returns in ethereum

The transaction returns occur when a contract or intelligent contract does not fulfill its promise or returns the errors for various reasons. These returns can be costly for developers as they may need to refund users or king -expenses.

For your problem, the problem is related to the “Transferhelper :: Transfer from”, which is likely to cause restores. The reason for this is that transfer from function fails when trying to replace the tokens from a title that does not have enough ether balance in their wallets.

Code Analysis

HERE IS A DETAIL OF YOUR CODE:

`Javascript

Const config = need ('./ config');

// ...

Transfereh :: Transfer from: transfer from

console.log (Error);

The “error” object contains the reasons for reset, which is probably a string that indicates who the transaction failed. In this case he says:

`

1 Transferhelper :: Transfer From: Transfer From

`

This suggests that the “Transferfrom” function in the “Transferhelper” Class has encountered a problem and returned 1.

Solution

To solve the return problem, you need to insure that your wallet titles get enough ether balance. Here are some possible solutions:

1. Check Your Wallet Balance

Make sure all your wallet titles get enough ether balance before trying to replace the chips.

`Javascript

Const title = '0x ...'; // wallet address

Const ethalce = waiting for etherscanclient.Gethalance (title);

If (ethalce <1010 * 18) {// 10 Ether Minimal Success for Success

throw a new error (not sufficient ether balance: $ {title});

}

`

2. Increase Your Wallet Balance

If your wallet balance is not sufficient, you may need to temporarily increase the balance before trying to replace.

`Javascript

Const title = '0x ...'; // wallet address

Const ethalce = waiting for etherscanclient.Gethalance (title);

if (ethalance <1010 * 18) {

Const Newethance = waiting for ethers.wallet.createwithsigner (ether).

Waiting for ethers.wallet.at (title) .portrove (Transfertoken, Ethbalance + 10);

}

3. Use a large ether -balance wallet

If your wallet addresses show sufficient ether -balance but still with mistakes, consider using a wallet with a high ether balance.

`Javascript

Const title = '0x ...'; // wallet address

Const ethalce = waiting for etherscanclient.Gethalance (title);

if (ethalance <10010 * 18) {

Const Newethance = ethers.wallet.createwithsigner (ether) .Tattach ('0x ...'). Ethers.wallet.at (title) .portrove (Transfertoken, Ethbalance + 10);

}

4. Update Etherscan API

If the reasons are due to the difference between the ether balance and the “Transferhelper” Class, consider an update to the Etherscan API to provide more accurate information.

`Javascript

Const config = need ('./ config');

Const etherscanapi = new etherscancanclient.etherscanapi ('your_api_key');

// ...

Etherscanapi.Gethalance (Title)

.Then ((balance) => {{{{

if (ethbalance! == balance) {

throw a new error (not sufficient ether balance: $ {title});

}

})

.Catch ((Error) => {{{{{

Console.error (Error);

});

`

If you implement one or more of these solutions, you should be able to solve the transaction’s return problem and successfully replace the tokens.

Example use the case

Here is the updated version of the code that contains some error handling:

“ Javascript

Const config = need (‘./ config’);

// …

Transfereh :: Transfer from: transfer from

Try {

Looking forward to ethers.wallet.at (title).
