A blockchain RPC gateway lets applications communicate directly with blockchain nodes. It provides endpoints to read on-chain data, send transactions, and interact with smart contracts. ## How many blockchains are supported? Our multi-chain RPC platform supports more than 70 Layer 1 and Layer 2 networks — including Ethereum, BNB Chain, Polygon, Solana, Tron, TON, Bitcoin, Avalanche, Arbitrum, and many others. ## Do you support both HTTPS and WebSocket connections? Yes. HTTPS is used for standard RPC calls, while WebSocket endpoints enable real-time updates for event-driven apps. ## Can I start using the RPC Gateway for free? Yes — create an API key in seconds and start testing with our free tier before upgrading to higher limits as your project grows. ## How is reliability ensured across RPC nodes? The infrastructure uses automatic failover, health checks, and distributed load balancing to maintain consistent uptime and response times worldwide. ## How fast is the RPC Gateway? Our nodes are deployed in multiple regions to minimize latency. You get consistently low-delay responses across North America, Europe, and Asia. ## What protocols or chains can I connect to? All major EVM and non-EVM chains — Ethereum, Polygon, BNB Chain, Avalanche, Arbitrum, Solana, Tron, TON, Bitcoin, and more — via a single RPC platform. ## How do I authenticate RPC requests? Use your personal API key in the request header for secure and trackable access. Keys can be rotated or revoked any time. ## Is the RPC Gateway suitable for production apps? Yes. It’s designed for both testing and production use cases — supporting dApps, wallets, and enterprise solutions that require stable and scalable node access. ## How can I monitor usage and performance? You can view real-time metrics — request volume, latency, and error rates — through the dashboard or via the analytics API for custom monitoring. ## How can I use the RPC Gateway in my project? Just generate an API key, choose the network, and start making RPC calls via HTTPS or WebSocket — no extra configuration required. ## What protocols does the RPC Gateway support? Standard JSON-RPC and WebSocket protocols compatible with all major blockchain clients and developer tools. #### Create blockchain magic with less effort [Start Building](https://auth.crypto-chief.com/registration)
