Read from a smart contract with Othent

Read Contract with Othent

Othent is library facilitating the onboarding of users from web2 to web3 through account abstraction. The authentication protocol offers a number of "wallet-less" functions for the same. Users can connect and interact with applications using web2 technologies like email accounts with the help of Othent.

The readContractWOthent function enables interacting with a deployed contract based on the input parameters.

{% hint style="info" %} Ensure you have pop-ups enabled in your browser for the URL you'll be using this function in. {% endhint %}

Basic Syntax

The function is called as follows:

import { readContractWOthent } from 'arweavekit/contract'

const readResult = await readContractWOthent({params});

Input Parameters

The following params are available for this function and they must be passed in as an object:

  • apiId: string : Use of any Othent function requires an apiId which can be fetched from othent.io. Towards the bottom of the linked page, the Get your API ID button provides the same.
  • contractTxId: string : The contractTxId points to the contract that is requested to be read.
Example 
const readResult = await readContractWOthent({
  apiId: string,
  contractTxId: '2W9NoIJM1SuaFUaSOJsui_5lD_NvCHTjez5HKe2SjYU'
});

This reads the current state of the contract whose id is specified as input.

Returned Data

The function call returns the following data:

  • state: object : The state is the information/ data stored with a contract. The read call returns the latest version of the state for the specified contract as reflected on the network.
  • errors: object : The errors object consists of metadata for any errors that may have occurred returning the read result or previous unsuccessful interactions with the contract.
  • validity : object The validity is the validity of the returned state of a contract.
