Question 1

What is an RPC endpoint for Sei?

Accepted Answer

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

Question 2

What are the best free Sei RPC endpoints?

Accepted Answer

RPC Directory lists multiple free public Sei 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 Sei testnet tokens?

Accepted Answer

Sei Testnet testnet tokens can typically be obtained from community faucets or by requesting them in the official Discord/Telegram channels. Testnet tokens have no real value and are only for testing purposes.

Question 4

What's the difference between Sei mainnet and testnet?

Accepted Answer

Sei 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 Sei 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

Does Sei support WebSocket connections?

Accepted Answer

Many Sei 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.
