Remote Procedure Call (RPC) nodes are an entry point for applications interacting with a blockchain network. They allow software programs to read blockchain data and broadcast new transactions to the network.

In the blockchain ecosystem, there are several companies and services that provide RPC node access across multiple chains, often called multichain RPC node providers. Some major ones include:

Infura (Ethereum, IPFS, and over 10+ EVM chains)
Alchemy (Ethereum, Polygon, Arbitrum, Optimism, and more)
QuickNode (Over 15+ chains including Ethereum, Polygon, BNB Chain, Avalanche)
Moralis (Ethereum, BSC, Polygon, Avalanche, and more)
Ankr (Bitcoin, Ethereum, Polygon, Avalanche, and 15+ other chains)

These providers offer reliable RPC node infrastructure, often with load balancing, high uptime, and easy integration via APIs or SDKs. Developers can use these services to build and run decentralized applications (dApps) that need to interact with multiple blockchain networks.

When choosing an RPC Node Provider for Multichain, consider factors like:

Cost: Some providers offer free tiers, while others have paid plans with more features.
Reliability: Look for a provider with a good uptime record and secure infrastructure.
Speed: Transaction speed can be important, especially for real-time applications.
Ease of use: Consider how easy it is to set up and use the provider's tools.
