Alchemy's Chain APIs are our implementation of the standard JSON-RPC interface (as defined by Ethereum) and compatible equivalents for non-EVM chains (e.g., Solana, Bitcoin). They provide direct, low-level access to blockchain data and functionality across all supported networks: read blockchain state, submit transactions, and build powerful decentralized applications.
Looking for higher-level building blocks? For indexed, enriched queries use the Data APIs. For account-abstraction and smart-wallet flows use the Wallet APIs.
Use these alongside the standard JSON-RPC methods for streaming, performance, and deeper inspection. Chain coverage varies: check each page for supported networks.
Subscribe to pending transactions, log events, new blocks, and more.
Get insights into transaction processing and onchain activity.
Non-standard RPC methods for inspecting and debugging transactions.
High-performance real-time Solana data streaming interface.
- Read Operations: Query account balances, smart contract state, transaction history, block data, and more
- Write Operations: Submit transactions to the network and track their status
- Event Monitoring: Subscribe to real-time blockchain events via WebSockets
- Gas Management: Estimate transaction costs and optimize gas usage
- Network Information: Access chain-specific data like network version, block numbers, and protocol details
Most chains use the same EVM JSON-RPC methods (e.g., eth_call, eth_getLogs, eth_sendRawTransaction); non-EVM chains provide compatible JSON-RPC or equivalent endpoints, plus chain-specific methods where the protocol differs. Each chain's section in the sidebar covers its full method list, endpoint URLs, and chain-specific behavior and limits.
