Ethereum: Can Gas Fees Be Paid from Another Account When Transferring Tokens Using Web3?
As the second-largest cryptocurrency by market capitalization, Ethereum has made significant progress in enabling smooth and efficient transactions. One of the key features that enables this flexibility is its use of Web3, the blockchain platform built on the Ethereum network. However, one common concern about Web3 transactions is whether gas fees can be paid from another account.
In this article, we’ll dive into the details of how gas fees work on the Ethereum network and whether paying them from an external account using Web3 is feasible.
Understanding Gas Fees
Gas fees are a key part of the Ethereum transaction process. They are used to pay for the computing power required by validators (also known as miners) to validate transactions on the network. The amount of gas paid depends on various factors such as:
Transaction complexity
Network congestion
Block size and difficulty
Web3: Blockchain Platform
To understand how Web3 transactions work, we need to briefly discuss their key features:
Interoperability: Web3 enables seamless interaction between different blockchain networks, including Ethereum.
Decentralized applications (dApps): Web3 facilitates the development of decentralized applications that can be built on different platforms and run on multiple networks.
Smart contracts: Web3 enables self-executing smart contracts 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 Ethereum consensus algorithm, validators (miners) must pay for their own gas consumption before they can validate a transaction.
However, this is where things get interesting. The Ethereum Virtual Machine (EVM) allows for the creation of reentrancy transactions, which allow smart contracts to be executed within an external account. This means that the external account can be used to pay gas fees without directly interacting with the validator’s wallet.
To achieve this, we need to use a technique called Web3 bridge
, also known as Inter-Chain Bridge (ICB)
or Cross-Chain Bridge. These bridges enable communication between different blockchains, enabling secure and efficient transactions across multiple chains.
Example Use Case: Using ICB
Here is an example of how you can use ICB to pay gas fees from an external account using Web3:
import { ethers } from 'ethers';
const web3 = new Web3(new Web3.providers.HttpProvider('
const icb = new ethers.providers.InternetChainBridge({
provider: icbProvider,
networkId: web3.eth.netID, // e.g. 'bsc',
});
// Define transaction data (e.g. gas price, gas limit)
const transactionData = {
amount: web3.utils.toWei('1', 'ether'), // pay $1 in Ethereum
};
// Create a new transaction instance using Web3
const tx = icb.createTransaction({
from: account_1,
to: '0xXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
data: transactionData,
});
// Sign the transaction using your private key
tx.sign(private_key_1);
// Broadcast the transaction across multiple chains (optional)
icb.sendTransaction(tx);
In this example, we create a new ICB client instance and use it to send a transaction from an external account to another account on the Ethereum network.
