## What is Bob?
BOB (Build on Bitcoin) is a hybrid OP Stack Layer-2 that runs full-EVM apps while anchoring finality to Bitcoin and enabling trust-minimized BTC bridging for Bitcoin-native DeFi.

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

## What is the Bob API?

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

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

## What methods are supported on Bob?

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