# Getting Started with Pimlico

Welcome to Pimlico, the world's most advanced ERC-4337 account abstraction infrastructure platform. This guide will help you understand Pimlico's ecosystem and get you started with building applications using our tools and services.

## What is Pimlico?

Pimlico provides a suite of tools and services to help you build, deploy, and manage smart accounts on Ethereum and other EVM-compatible chains. Our infrastructure powers the next generation of web3 applications by making account abstraction accessible and easy to implement.

## Core Products

Pimlico offers several key products that work together to provide a complete account abstraction solution:

### permissionless.js

A TypeScript library built on viem for interacting with ERC-4337 bundlers, paymasters, and user operations. It provides:

* High-level smart account support for popular implementations (Safe, Kernel, Biconomy, TrustWallet, etc.)
* Bundler support for all ERC-4337 actions
* Gas sponsorship capabilities
* User Operation utility functions
* Modular and extensible architecture

### Bundler

Our Alto Bundler is a performant, type-safe ERC-4337 bundler written in TypeScript that powers smart accounts by relaying user operations for fast and reliable on-chain inclusion. Key features include:

* Full type safety
* Transaction inclusion reliability
* Fast transaction inclusion speed
* Support for 100+ EVM chains

### Paymasters

Pimlico offers two types of paymasters to abstract away gas fees for your users:

1. **Verifying Paymaster**: Sponsor on-chain gas fees for your users across 100+ chains, with no upfront funding: add a card and pay for usage at the end of each month, or pre-load a balance in the dashboard.

2. **ERC-20 Paymaster**: A permissionless on-chain smart contract that lets your users pay for their own gas fees using ERC-20 tokens.

## Quick Start

The fastest way to get started with Pimlico is to follow our step-by-step tutorials:

### Tutorial 1: Send Your First Gasless Transaction

In this tutorial, you'll learn how to:

* Set up the necessary permissionless.js clients
* Create a user operation
* Use Pimlico's verifying paymaster to sponsor gas fees
* Submit the operation on-chain with Pimlico's bundler

### Tutorial 2: Pay for Gas with ERC-20 Tokens

Learn how to use Pimlico's ERC-20 paymaster to allow users to pay for their transactions with tokens instead of ETH.
