Integration

This guide focuses on the code to integrate the entry point gas estimations package.

Installation

First, install the required packages for initializing the gas estimator client

npm

npm i entry-point-gas-estimations

yarn

yarn add entry-point-gas-estimations

Integration

import { createGasEstimator } from "entry-point-gas-estimations";

// Creating a general gas estimator client
const gasEstimator = createGasEstimator({
  rpcUrl,
});

// L2s have a different way of calculating the preVerificationGas
// which requires creating network-specific gas estimator clients

// Optimism Stack Networks
const optimismGasEstimator = createOptimismGasEstimator({
  rpcUrl,
});

// Arbitrum Networks
const arbitrumGasEstimator = createArbitrumGasEstimator({
  rpcUrl,
});

// Mantle Networks
const mantleGasEstimator = createMantleGasEstimator({
  rpcUrl,
});

// Scroll Networks
const scrollGasEstimator = createScrollGasEstimator({
  rpcUrl,
});

Parameters

• rpcUrl(string, required): RPC Url of the network
• entryPointAddress(string): optional entry point if it is different than 0x5FF137D4b0FDCD49DcA30c7CF57E578a026d2789

returns

• gasEstimator(Promise<GasEstimator>): gas estimator instance
