## What is Plasma?
Plasma is an EVM-compatible Layer-1 purpose-built for stablecoins, using PlasmaBFT (Fast HotStuff) and a native Bitcoin bridge to enable near-instant, zero-fee USD₮ transfers and confidential payments.

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

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

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

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

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

## What is a Plasma API key?
When accessing the Plasma 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 you [sign up for a free API key](https://dashboard.alchemy.com/signup).

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