The RPC protocol

The Tezos RPC (Remote Procedure Call) protocol is a specification for a REST API that clients use to interact with Tezos nodes and nodes use to communicate with each other. Tezos nodes act as servers and accept HTTP requests from clients and other nodes via this protocol.

  • Clients use it to submit transactions and get information about the state of the blockchain, such as account balances and contract storage
  • Nodes use it to bake blocks and communicate with other nodes

Tezos RPC uses JSON to send and receive data, but it does not adhere to the JSON-RPC specification.

RPC nodes​

Not all Tezos nodes run RPC servers, and not all RPC servers accept requests from any client. When you work with a Tezos client, such as the Octez command-line client or the Taquito SDK, you select a public RPC node to send transactions to, or you can use a private RPC node that you have access to.

If you're using a testnet, you can get a list of public RPC nodes for that network at https://teztnets.xyz.
