How to use it

// Import required libraries and modules from Tatum SDK
import { TatumSDK, Tezos, Network } from '@tatumio/tatum';

// Initialize the Tatum SDK for Tezos
const tatum = await TatumSDK.init<Tezos>({ network: Network.TEZOS });

// Define the protocol information as an object
const protocolInfo = {
    expected_env_version: 'YOUR_ENV_VERSION',  // Replace with the expected environment version
    components: [
            name: 'COMPONENT_NAME',           // Replace with the component name
            interface: 'COMPONENT_INTERFACE', // Replace with the component interface
            implementation: 'COMPONENT_IMPL'  // Replace with the component implementation
    async: false  // Optional: Set to 'true' for asynchronous injection

// Inject a protocol into the node
const protocolId = await tatum.rpc.injectProtocol(protocolInfo);

// Log the protocol ID
console.log('Protocol ID:', protocolId);

// Always destroy the Tatum SDK instance when done to stop any background processes
await tatum.destroy();


The injectProtocol method allows you to inject a protocol into the Tezos node. It returns the ID of the injected protocol. By default, the RPC waits for the protocol to be validated before returning. However, setting async to 'true' makes the function return immediately.

Example Use Cases

  1. Protocol Upgrade: Developers can use this method to inject protocol upgrades and improvements into the Tezos network.

  2. Network Maintenance: Validators and administrators can inject protocol updates to perform network maintenance and ensure the stability and security of the blockchain.

Request Parameters

The injectProtocol method accepts the following parameter:

  • expected_env_version (string, required): The expected environment version of the protocol.

  • components (array of objects, required): An array of components that make up the protocol. Each component should include:

    • name (string): The name of the component.

    • interface (string): The interface of the component.

    • implementation (string): The implementation of the component.

  • async (boolean, optional): Set to 'true' to receive an asynchronous response. Default is 'false'.

Return Object

The injectProtocol method returns an object containing the ID of the injected protocol:

  • protocolId (string): A Tezos protocol ID in Base58Check-encoded format.

(Note: The exact fields in the return object might vary based on the Tezos blockchain's implementation and version.)
