# Overview

> Explore Base JSON-RPC methods

## Introduction

Base is an Ethereum Layer 2 (L2) network that offers high-speed, low-cost transactions with the security of Ethereum. It leverages the Optimism rollup technology to process transactions off-chain, reducing fees and improving throughput. Base is designed to bring the power of Ethereum to more developers and users, enabling a more scalable decentralized finance (DeFi) ecosystem, NFTs, and other dApps.

## Supported Networks

The Base RPC API is available for the following networks:

1. **Base Mainnet**
2. **Base Sepolia Testnet**

## Network Details

| **Network**      | **Chain ID**    | **Path Parameter** |
| :--------------- | :-------------- | :----------------- |
| **Base Mainnet** | 0x2105 (8453)   | `base`             |
| **Base Sepolia** | 0x14a34 (84532) | `base-sepolia`     |
