Deploy a Smart Contract on Your Subnet-EVM Using Remix and MetaMask


This tutorial assumes that:

Step 1: Setting up MetaMask

EVM Subnet Settings: (EVM MetaMask Tutorial)

  • Network Name: Custom Subnet-EVM
  • New RPC URL: http://NodeIPAddress:9650/ext/bc/BlockchainID/rpc (Note: the port number should match your local setting which can be different from 9650.)
  • ChainID: Subnet-EVM ChainID
  • Symbol: Subnet-EVM Token Symbol
  • Explorer: N/A

You should see a balance of your Subnet's Native Token in MetaMask.

Step 2: Connect MetaMask and Deploy a Smart Contract

Using Remix

Open Remix -> Select Solidity.

remix Subnet evm sc home

Create the smart contracts that we want to compile and deploy using Remix file explorer

Using GitHub

In Remix Home Click the GitHub button.

remix Subnet evm sc load panel

Paste the link to the Smart Contract into the popup and Click import.

remix Subnet evm sc import

For this example, we will deploy an ERC721 contract from the Avalanche Smart Contract Quickstart Repository.

remix Subnet evm sc file explorer

Navigate to Deploy Tab -> Open the "ENVIRONMENT" drop-down and select Injected Web3 (make sure MetaMask is loaded).

remix Subnet evm sc web3

Once we injected the web3-> Go back to the compiler, and compile the selected contract -> Navigate to Deploy Tab.

remix Subnet evm sc compile

Now, the smart contract is compiled, MetaMask is injected, and we are ready to deploy our ERC721. Click "Deploy."

remix Subnet evm sc deploy

Confirm the transaction on the MetaMask pop up.

Our contract is successfully deployed!

Now, we can expand it by selecting it from the "Deployed Contracts" tab and test it out.

The contract ABI and Bytecode are available on the compiler tab.

Other Tools

You can use Subnet-EVM just like you use C-Chain and EVM tools. Only differences are chainID and RPC URL. For example you can deploy your contracts with hardhat quick start guide by changing url and chainId in the hardhat.config.ts.
