# RPC Nodes

> Moralis Nodes give you reliable, low-latency access to blockchain networks for reading data and submitting transactions - ideal for powering wallets, dapps, indexers, bots, and custom infrastructure at scale.

## Overview

**Moralis RPC Nodes** provide reliable, low-latency access to blockchain networks for reading on-chain data and submitting transactions.

Instead of running your own nodes, Moralis handles the infrastructure so you can focus on building your application.

***

## What Are RPC Nodes?

RPC (Remote Procedure Call) nodes are your gateway to blockchain networks. They allow you to:

* **Read Data** - Query blockchain state, balances, and transactions
* **Submit Transactions** - Send signed transactions to the network
* **Subscribe to Events** - Listen for new blocks and contract events
* **Access Archives** - Query historical blockchain state

***

## Key Features

* **High Availability** - 99.9% uptime SLA
* **Low Latency** - Optimized for fast response times
* **Multi-Chain** - Support for 20+ blockchain networks
* **Archive Access** - Full historical data on supported chains
* **WebSocket Support** - Real-time subscriptions and event streaming
* **Rate Limits** - Generous limits with burst capacity
* **Global Distribution** - Edge nodes for reduced latency

***

## Supported Networks

Moralis RPC Nodes support major blockchain networks:

* **Ethereum** - Mainnet and testnets
* **Polygon** - PoS and zkEVM
* **BNB Chain** - BSC and opBNB
* **Arbitrum** - One and Nova
* **Optimism** - Mainnet
* **Base** - Mainnet
* **Avalanche** - C-Chain
* **And more** - Linea, zkSync, Blast, Mantle, and others

***

## Common Use Cases

* **Wallets**\
  (query balances and submit transactions)
* **dApps**\
  (interact with smart contracts)
* **Indexers**\
  (fetch and process blockchain data)
* **Trading Bots**\
  (monitor mempool and execute trades)
* **Analytics**\
  (query historical blockchain state)
* **Backend Services**\
  (reliable blockchain connectivity)
