Question 1

What is an RPC endpoint for Cronos?

Accepted Answer

An RPC (Remote Procedure Call) endpoint is a URL that allows your application to communicate with the Cronos blockchain. Through RPC endpoints, you can read blockchain data, submit transactions, query account balances, and interact with smart contracts without running your own Cronos node.

Question 2

What are the best free Cronos RPC endpoints?

Accepted Answer

RPC Directory lists multiple free public Cronos endpoints you can use for development and low-traffic applications. Public endpoints are rate-limited and may experience downtime during high traffic. For production applications, consider using a paid RPC provider for better reliability and higher rate limits.

Question 3

How do I get free Cronos testnet tokens?

Accepted Answer

You can get free Cronos Testnet testnet tokens from the official faucet. Visit the faucet link in the Resources section above. Testnet tokens have no real value and are only for testing and development purposes.

Question 4

What's the difference between Cronos mainnet and testnet?

Accepted Answer

Cronos mainnet is the production network where real transactions with actual value occur. Testnets like Testnet are testing environments with tokens that have no real value. Always test your applications on testnet before deploying to mainnet to avoid costly mistakes.

Question 5

What's the difference between free and paid Cronos RPC providers?

Accepted Answer

Free public endpoints have rate limits (typically 10-100 requests/second), may experience downtime during high traffic, and offer limited features. Paid providers offer higher rate limits (1000+ RPS), better reliability with SLAs, additional features like archive data access, WebSocket connections, and dedicated support. Use the pricing calculator above to compare costs.

Question 6

How is Cronos RPC different from other blockchains?

Accepted Answer

Cronos is built on the Cosmos SDK, using Tendermint consensus. It has two types of endpoints: Tendermint RPC for consensus-level queries and LCD (Light Client Daemon) REST API for application queries. Both are listed on this page. Cosmos chains can also communicate with other Cosmos chains via IBC (Inter-Blockchain Communication).

Question 7

Does Cronos support WebSocket connections?

Accepted Answer

Many Cronos RPC providers offer WebSocket (WSS) endpoints for real-time subscriptions to new blocks, pending transactions, and contract events. WebSocket connections are ideal for applications that need instant updates without polling. Check the endpoints list above for available WSS URLs.
