## What is MegaETH?
MegaETH is a high-performance Ethereum Layer 2 blockchain designed to achieve real-time transaction processing with sub-millisecond latency and extremely high throughput.

## How do I get started with MegaETH?
Check out our [MegaETH API Quickstart guide](/docs/reference/megaeth-api-quickstart) to get started building on MegaETH.

## What is the MegaETH API?
The MegaETH API lets you interface with the MegaETH mainnet. You can execute transactions, query onchain data, and interact with the MegaETH network using the JSON-RPC standard.

## Is MegaETH EVM compatible?
Yes, MegaETH is EVM compatible.

## What API does MegaETH use?
MegaETH uses the JSON-RPC API standard. This API handles all blockchain interaction on the MegaETH network, letting you read block/transaction data, query chain information, execute smart contracts, and store data onchain.

## What methods are supported on MegaETH?
MegaETH supports standard Ethereum JSON-RPC methods. Some chain-specific methods may vary. Please check the [MegaETH API Endpoints](/docs/chains#megaeth-apis) for a complete list.

## What is a MegaETH API key?
When you access the MegaETH network via a node provider like Alchemy, you use an API key to send transactions and retrieve data from the network. For the best development experience, we recommend that you [sign up for a free API key](https://dashboard.alchemy.com/signup)!

## Which libraries support MegaETH?
Common Ethereum libraries like [ethers.js](https://docs.ethers.org/v5/) should be compatible with MegaETH, given its EVM nature.
