Ethereum: Can gas fees be paid from another account when transferred by token using a web3?

As the second largest currency of market capitalization, Ethereum has achieved significant steps in enabling noises and effective transactions. One of the key features that enables such flexibility is the use of web3, blockchain platform built on top of the Ethereum network. However, one common concern about web3 transactions is whether gas fees can be paid from another account.

In this article, we will investigate details of how gas fees function on the Ethereum network and explore whether it is feasible to pay them from an external account using a web3.

Understanding gas fees

Gas fees are a critical component of the Ethereum transaction process. It is used to pay for a computer power required by validators (known as miners) to confirm the transactions on the network. The amount of gas paid depends on different factors, such as:

• The complexity of the transaction

• Network congestion

• The size and difficulty of the block

Web3: Blockchain platform

In order to understand how web3 transactions work, we must briefly touch on its key features:

* Interoperability: Web3 enables no merits between different blockchain networks, including Ethereum.

* Decentralized applications (DAPPS): Web3 makes it easier to develop decentralized applications, which can be built on different platforms and run on multiple networks.

* Smart Contracts: Web3 allows you to execute smart contracts that only execution that automate transactions without the need for intermediaries.

Paying gas fees from another account

Now, let’s consider whether it is possible to pay gas fees using an external account. According to the algorithm of the consensus of Ethereum, the validators (miners) must pay their own gas consumption before they can confirm the transaction.

However, things become interesting here. Ethereum Virtual Machine (EVM) allows you to create
Reentrancy transactions that allow you to execute smart contracts within an external account. This means that the external account can be used to pay gas fees without direct interaction with the wallet wallet.

To achieve this, we need to use a technique called
web3 bridge, also known as
Bridge of the Intermediate (ICB) or
Bridge of the cross chain

. These bridges allow communication between different blockchain networks, allowing safe and effective transactions into multiple chains.

Example uses the case: use ICB

Here’s an example of how you can use the ICB to pay gas fees from an external account using Web3:

`Javascript

Import {Ethers} from ‘Ether’;

Const Web3 = New Web3 (new web3provders.httpprovider (‘

Const Account_1 = ‘0xxxxxxxxxxxxxxxxxxxxxxxxxxx’;

Const Private_KEY_1 = ‘…’; // your private key

// Get an ICB service provider

Const iCbProvider = etherS.provider;

// Create a new instance of ICB client

Const ICB = New ETERS.PROVIDERSS.IINTERNTCHAINBRIDGE ({{{

Provider: ICBPROVIDER,

Networkid: Web3.esth.netid, // eg ‘BSC’,

});

// Define transaction data (eg gas price, gas limit)

Const transactional = {

amount: web

};

// Create a new instance of transaction using a web3

Const TX = ICB.Createransation ({{{

From: Account_1,

to: ‘0xxxxxxxxxxxxxxxxxxxxxxxxxxx’,

Data: Transactionate,

});

// Sign the transaction using a private key

tx.sign (private_key_1);

// broadcast a transaction in multiple chains (optional)

ICb.sendtransation (TX);

``

In this example, we create a new instance of ICB client and use it to send a transaction from an external account to another account online.
