RPC Nodes Overview
Welcome to the Moralis RPC Nodes documentation! This section will guide you through everything you need to know to effectively use Moralis RPC Nodes for accessing blockchain data across various supported networks. Our RPC nodes provide a powerful and reliable gateway for interacting with blockchain networks using standard JSON-RPC calls.
What Are RPC Nodes?​
RPC (Remote Procedure Call) nodes allow developers to interact with blockchain networks without the need to run their own full node. By sending JSON-RPC requests to Moralis RPC Nodes, you can:
- Query blockchain data (e.g., block and transaction information).
- Interact with smart contracts.
- Fetch NFT and token balances.
- Send transactions and monitor on-chain events.
Moralis simplifies this process by providing reliable, scalable access to RPC nodes across major blockchain networks.
