I’m under no circumstances a Javascript professional (or a JS Ninja/Expert)!

The code is not production-ready! (only for learning purposes)

In this guide, I’m going to show you how to read a smart contract function on MATRIX AI NETWORK.

This is also a continuation of the last guide:

and the one in which we deploy the contract

I will use the following solidity smart contract for this example:

We will make use of the following packages : ‘aiman’, ‘matrixjs-tx’, ‘bignumber.js’, ‘bs58’, ‘fs’.

You can install them by using :

npm install aiman fs

and declare them:

Now I will initialize ‘aiman’ with a provider, read the contract ABI and put it in a variable, also declare the smart contract address:

In the next function I will initialize a contract instance with the ABI, make it use the contract address and call the “get” method of the smart contract:

Then solve the promise:

The program will output the value contained within the “result” variable of the smart contract (the function got called with 152,58 as input parameters last time).
