## What is Gensyn?
Gensyn Chain is an EVM-compatible custom Ethereum rollup purpose-built for machine learning -- coordinating jobs, verifying training, and paying compute providers onchain.

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

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

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

## What API does Gensyn use?
Gensyn uses the JSON-RPC API standard. This API is essential for any blockchain interaction on the Gensyn network, allowing you to read block/transaction data, query chain information, execute smart contracts, and store data onchain.

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

## What is a Gensyn API key?
When accessing the Gensyn 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 Gensyn?
Common Ethereum libraries like [ethers.js](https://docs.ethers.org/v5/) should be compatible with Gensyn, given its EVM nature.
