Deploy a Smart Contract on Your Subnet EVM Using Remix and Metamask
This tutorial assumes that:
- An Subnet and EVM blockchain has been created
- Your Node is currently validating your target Subnet
- Your wallet has a balance of the Subnet Native Token(Specified under alloc in your Genesis File).
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
You should see a balance of your Subnet's Native Token in Metamask.
Step 2: Connect MetaMask and Deploy a Smart Contract
Open Remix -> Select Solidity.
Create the smart contracts that we want to compile and deploy using Remix file explorer
In Remix Home Click the GitHub button.
Paste the link to the Smart Contract into the popup and Click import.
For this example, we will deploy an ERC721 contract from the Avalanche Smart Contract Quickstart Repo.
Navigate to Deploy Tab -> Open the "ENVIRONMENT" drop-down and select Injected Web3 (make sure MetaMask is loaded).
Once we injected the web3-> Go back to the compiler, and compile the selected contract -> Navigate to Deploy Tab.
Now, the smart contract is compiled, MetaMask is injected, and we are ready to deploy our ERC721. Click "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.

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
chainId in the
