Explore Base, a new Layer 2 blockchain built to enhance scalability and security. Discover its potential for dApps, DeFi, and more.
The Base RPC documentation offers developers a comprehensive guide to interact with the Base Layer 2 network, built on the Optimism stack. Through its detailed API endpoints, developers can query blockchain data, manage accounts, submit transactions, and interact with Ethereum-compatible smart contracts. Base is designed to enhance Ethereum’s scalability by providing faster transaction times and lower fees, while still maintaining security. This documentation supports developers in building and migrating dApps, with examples and best practices for seamless integration.
