FAQs
What is JSON-RPC?
JSON-RPC is a lightweight remote procedure call protocol that uses JSON to encode messages. It's widely used in blockchain interactions for its simplicity and efficiency.
How do I subscribe to block updates?
Use eth_subscribe with "newHeads" as the subscription type to receive notifications about new blocks.
Can I send transactions without unlocking my account?
Yes, using eth_sendRawTransaction with a pre-signed transaction allows you to send transactions without account unlocking.
