Deploy contract with Remix

How to deploy a smart contract to ParaTon testnet, mainnet, or a local network using Remix.

Introduction to Remix

Remix is an online IDE that you can use to rapidly develop and deploy smart contracts. If you're new to smart contracts, it's a great tool that lets you jump right in without needing to configure a local editor or struggle through environment configuration issues before getting started.

To learn more about the features available to you as a smart contract developer with Remix, visit the Remix documentation.

Create a Smart Contract

• Create a new contract file named "Cat.sol".

• Next, we will use the NFT contract generated on the previous page and paste the code into "Cat.sol".

• Complete any changes to your smart contract and save the final version (Command/Ctrl + S).

After waiting for a few seconds, Remix will load the OpenZeppelin contracts.

Compile the Contract

• Choose the Solidity Compiler Icon on the left side menu.

• Check that your compiler version is within the versions specified in the pragma solidity statement.

• Select the Compile button to compile your smart contract.

• 

Deploy the Contract​

• Click the Deploy and Run Transactions Icon on the left side menu.

• Choose Injected Web3 as your environment.

• Connect MetaMask to ParaTon testnet and verify that the environment reads:

  • Custom (xxx) network for ParaTon testnet

  • Custom (xxx) network for ParaTon mainnet

• Click Deploy and select Confirm in the MetaMask notification window to pay for the transaction
