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 });

const params = {
    contractId: 'YOUR_CONTRACT_ID',     // Specify the contract ID
    chainId: 'YOUR_CHAIN_ID',           // Specify the chain ID (Network identifier)
    blockId: 'YOUR_BLOCK_ID',           // Optional: Specify the block ID if needed
    normalizeTypes: false               // Optional: Set to true if you want to normalize types

// Retrieve the list of entrypoints of the Tezos smart contract
const entrypoints = await tatum.rpc.getContractEntrypoints(params);

// Log the list of entrypoints
console.log(`Entry Points of Contract ${params.contractId}:`, entrypoints);

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


The getContractEntrypoints method is used to return the list of entrypoints available in a specific Tezos smart contract. Entrypoints represent the callable functions or methods that can be invoked on the contract.

Example Use Cases:

  1. Contract Interaction: Developers and users can use this method to discover the available entrypoints of a smart contract. This information is essential for interacting with and invoking specific contract functions.

  2. Contract Analysis: Analysts and auditors may use this method to examine the contract's exposed functions and ensure that they align with the intended functionality.

Request Parameters

The getContractEntrypoints method requires the following parameters:

  • contract_id (string, required): A contract identifier encoded in b58check, representing the Tezos smart contract for which you want to retrieve the list of entrypoints.

  • chainId (string, required): The ID of the chain where the block is located.

  • blockId (string, required): The unique identifier (hash) of the block.

  • normalize_types (boolean, optional): Indicates whether types should be normalized. If set to true, types will be normalized (annotations removed, combs flattened); if set to false, types will be kept as they appeared in the original script.

Return Object

The method returns an object containing the following properties:

  • unreachable (array of objects): An array of unreachable entrypoints. Each object in the array contains a path property, which is an array of Michelson primitives.

  • entrypoints (object): An object containing the available entrypoints of the contract. Each entrypoint is represented as a property, and its value is a Micheline expression describing the entrypoint's type.

Users can use this information to understand the contract's callable functions and types.

Please note that the normalize_types parameter can affect the structure of the returned entrypoints based on whether types are normalized or kept as they appeared in the original script.

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