Mode is an OP Stack Layer 2 designed for hyper-growth that directly rewards developers, users and protocols to grow Mode and Optimism Superchain ecosystem. Mode is EVM compatible, allowing you to easily port your existing Ethereum-based smart contracts without modifying the code.

In this tutorial, you will learn how to deploy a smart contract on Mode using the Remix IDE. You will also participate in their Galxe campaign and join their Testnet to get a potential airdrop.

Step 1: Claim Faucet Sepolia

Step 2: Add network in Metamask
Name : Mode Testnet
Chain ID : 919
Symbol : ETH
Block Explorer :

Step 3: Bridge Sepolia ETH to Mode Network:

To use your Sepolia ETH on Mode network, you need to bridge them using Enter the amount of Sepolia ETH you want to bridge and click “Transfer”. Confirm the transaction on MetaMask and wait for it to be processed.

Step 4: Claim Points on Galxe:

Step 5: Deploy Smart Contract on Remix

(1) Go to Remix IDE and open the ‘1_Storage.sol’ smart contract in the workspace.

(2) To compile your smart contract, go to the Solidity Compiler tab and select the contract you want to compile. Click on “Compile”, you can also enable “Auto Compile” for automatic compilation whenever you change the contract code.

(3) Once the smart contract is compiled successfully, switch to the “Deploy & Run Transactions” tab. In the “Environment” dropdown menu, select “Injected Provider — MetaMask”; this will connect your MetaMask to Remix and will allow you to make transactions from that connected wallet.

(4) Make sure to have Mode as your selected network in MetaMask before deploying. Select the compiled contract you want to deploy and click ‘Deploy.’ Now, MetaMask should pop up and ask you to confirm the transaction with super low fees.

Step 6: Interact with Smart Contract:

You will see your deployed smart contract below in the ‘Deploy & Run Transactions’ tab. Copy the contract address from Remix, go to Blockscout, and paste it into the search bar.

In this tutorial, you learned how to deploy a smart contract on Mode testnet network using Remix IDE. You also participated in their Galxe campaign and joined their Testnet to get a potential airdrop.
