Web3.js version 2: Airdrop wants work to confirm, but the balance remains zero
As web3.js version 2 continues to gain popularity among developers, it has introduced several new features that aim to improve the consumer experience. In some cases, however, these updates can lead to unexpected behavior when it comes to Airdropops.
In this article, we will look at the question of Airdrop’s request with a confirmation completed using the Web3.js version 2 and check that the balance after the transaction remains zero.
The problem: Confirmation is complete but zero balance
When you ask for Airdrop on Web3.js version 2, it essentially launches an intelligent contract that will distribute tokens to users. To initiate this process, you must send a message Request Enarp 'with the required parameters. In our example, we will use the "Completed" confirmation option.
Here is some sample code ofweb3.js:
Javascript
CONST Web3 = Requirement ('Web3');
CONST W3 = New Web3 (new web3.providers.httpprovider ('
// Create a web3 copy
CONST Web3 = New Web3 (W3);
// Define AirDrop parameters
Permanent parami = {
From: '0x1234567890ABCDEF', // Sender address
A: '0x9876543210FEDCBA', // Directorate of Discussion
Quantity: 1000, // number of tokens to distribute
Deadline: 90000, // Performance time for seconds
Nance: 1, // Number of original transactions
};
// Create a new account (not necessary for this example)
Const myacount = web3.eth.acount [0];
// Make an Airdrop app with confirmation
Web3.Requeaseirdrop (Params)
.ON ('Confirmation', function (confnum) {
Console.log (Confirmation $ {confnum} of $ {params.amount});
})
.ON ('error', function (error) {
Console.error ('Error:', error.message);
})
.Then (function (result) {
// Check that the transaction is completed
If (score.Status === 0 && results
Console.log ('Airdrop confirmed!');
} others {
Console.log ("Error: transaction is not completed.");
}
})
.ON ('balance of', function (recybalance) {
Console.log (balance: $ {recipalance});
});
In this code we create a new account and make the messageRequestDropwith the necessary parameters. We also register the transaction confirmation number.
The interesting part comes when we check the balance after the transaction is done:
Javascript
// Check that the balance is not zero
web3.eth.getbalance (myacount) .Then (function (balance) {
Console.log (initial balance: $ {balance});
web3.eth.getbalance (myaccount) .Then (function (received from time) {
// Check that the resulting balance is different from the original balance
If (recipalance! == Balance) {
Console.log ('' initial and balance obtained are not the same! ');
}
});
});
In this example, we useweb3.eth.getbalanceto check the current balance of our account. We then compare it to the initial balance obtained from the messagerequest Aardrop.
Sentence: Balance remains zero
Unfortunately, in our exemplary code, the balance after the transaction remains zero. This is not a mistake in itself, but rather the result of how web3.js version 2 processes complete confirmations.
In order to achieve the desired result, when the balance after execution of the message "Requires is not zero, you must change its code to include additional logic for calculating and updating the balance. This may include the use ofweb3.eth.getbalance` several times or to implement a personalized calculation function.
I hope this article has provided valuable information about Web3.
