What is Base?

Base is a Layer 2 scaling solution for Ethereum built by Coinbase using the OP Stack, the same technology powering Optimism. Base uses optimistic rollup technology to process transactions off-chain while posting compressed data to Ethereum mainnet for security.

Base implements EVM equivalence at the bytecode level through the Optimism Virtual Machine. The network uses sequencers to order transactions and achieve fast block times. Base inherits Ethereum's security through a fraud proof window during which invalid state transitions can be challenged. The network uses ETH for gas fees and supports all Ethereum transaction types including EIP-1559.

Interacting with Base

Base nodes expose a JSON-RPC interface that provides full compatibility with Ethereum's API while adding L2-specific functionality. The Base JSON-RPC API enables seamless migration of Ethereum applications.

With this API, you can:

Execute all standard Ethereum JSON-RPC methods (eth_call, eth_sendTransaction, eth_getBalance)
Access L2-specific methods for gas estimation and rollup operations
Access Flashblocks API
Subscribe to real-time events via WebSocket connections

You can access the API by:

Using a hosted provider such as a QuickNode Base endpoint, which delivers low-latency global access, archive data, and enhanced reliability out of the box
