Create Smart Contract

There are multiple ways to create a smart contract via the Kriptonio platform.

Using the web interface

The simplest way to create a smart contract is to use our web interface.

Simply go to Smart Contract -> New Smart Contract and choose how you want to create your smart contract.

You can paste your Solidity source code, upload a file, or use one of our configurable smart contract templates.

After saving the smart contract, Kriptonio will automatically compile it, and prepare for you a web interface for deploying, interacting with, and monitoring your smart contract.

Using Hardhat / Truffle plugins

Using SDK

You can also use our SDK to create a smart contract. In order to do that, you will need to obtain and provide a Standard JSON Input object.

Here is an example of creating an empty smart contract using the SDK:

import { ChainId, KriptonioSdk } from '@kriptonio/sdk';
const sdk = new KriptonioSdk({
  accessToken: 'your-access-token',

const smartContract = await sdk.smartContract.createFromStandardJson({
  data: {
    title: 'Title of my smart contract',
    chainId: ChainId.Polygon,
    contractFile: 'Test.sol',
    contractName: 'Test',
    contractStandardJson: JSON.stringify({
      language: 'Solidity',
      sources: {
        'Test.sol': {
          content: 'pragma solidity ^0.8.0; contract Test { }',
      settings: {
        optimizer: {
          enabled: true,
          runs: 200,
        outputSelection: {
          '*': {
            '*': ['metadata', 'abi', 'evm.bytecode', 'evm.bytecode.sourceMap'],
