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.
Check out our Bob API Quickstart guide to get started building on Bob.
The Bob API lets you interface with the Bob mainnet. With this API, you can execute transactions, query onchain data, and interact with the Bob network using the JSON-RPC standard.
Yes, Bob is EVM compatible.
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.
BOB supports standard Ethereum JSON-RPC methods. Some chain-specific methods may vary. Please check the BOB API Endpoints for a complete list.
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.
Common Ethereum libraries like ethers.js should be compatible with Bob, given its EVM nature.
