eth_gasPrice code examples

const { Web3 } = require("web3");

const NODE_URL = "CHAINSTACK_NODE_URL";

const web3 = new Web3(NODE_URL);



async function getGasPrice() {

    const baseFee = await web3.eth.getGasPrice();

    const feeInGwei = web3.utils.fromWei(baseFee, "gwei")

    console.log(`The base gas fee is: ${baseFee} Wei`);

    console.log(`The base gas fee is: ${feeInGwei} Gwei`);

  }

Use case

You can use eth_gasPrice to calculate the total gas value to send with a transaction based on the base and priority fee system. Ethereum’s London hard fork implemented This concept with EIP-1559.

EIP-1559 aimed to solve the problem of network congestion by implementing a dynamic fee market mechanism, which adjusts the fee required to process a transaction based on network demand. With the current system, the total gas price comprises a base fee determined by the network’s load and a priority fee added by the user.

Note

The eth_gasPrice method returns the base fee.
