Cookbook.dev

Cookbook.dev is an open-source smart contract registry where developers can find solidity primitives, libraries, and smart contracts for protocols. It provides an easy and fast way to develop smart contracts by integrating with a variety of blockchain-native developer tools.

Here, we'll walk through searching for a protocol on Cookbook and deploying it to Linea using Cookbook's no-code deploy and using Cookbook with Remix, Hardhat and Foundry.

Prerequisites

Before you begin, ensure you:

1. Set up your wallet
2. Fund your wallet with Linea ETH on either the testnet or mainnet

Search Cookbook's smart contract registry

Navigate to cookbook.dev/chains/Linea and explore Protocols on Linea, or search for specific smart contracts in the search bar.

To learn about a smart contract on Cookbook, select the protocol, and select Expand. This opens the code alongside ChefGPT, Cookbook's AI Solidity assistant.

Highlight selections of the code and press Analyze Snippet to get more information about the smart contract code you're looking at, or ask ChefGPT questions about Linea, solidity, or your smart contract.

Import smart contract code into Cookbook

Import verified smart contract code into Cookbook to fork, learn about, or build with by inputting any smart contract address that's verified on an EVM-based block explorer into the Cookbook.dev search bar.

Deploy a smart contract without coding

Choose No-Code Deploy on select (usually simpler) smart contracts on Cookbook.

1. Connect your MetaMask Wallet to Cookbook.dev.

2. Set your smart contract arguments in the Cookbook UI (if applicable).

3. Select Linea or tLinea (Linea Testnet) under Pick Chain.

4. Select Deploy and pay the network fee.

Manage your deployed smart contract under My Dashboard in Cookbook.

Deploy your smart contract using Remix

Method 1 - Use the Cookbook.dev website and open in Remix

On a smart contract or protocol page in Cookbook, select the Open in Remix option. Your smart contract will automatically be opened in a new Remix workspace.

Select Compile to compile your smart contract in Remix. Most contracts opened with Cookbook will automatically compile within Remix.

Refer to the Remix instructions for more information on how to compile and deploy smart contracts in the Remix IDE.

Method 2 - Use the Cookbook Remix plug-in within the Remix IDE

1. Go to Remix.Ethereum.org website.

2. Add the Cookbook Plugin to Remix by clicking the Cookbook Logo under Featured Plugins on the Remix Homepage.

   

   Alternatively, search Cookbook and select Activate in the Remix Plugin Manager.

   

3. Search for any protocol or smart contract and click the search result to import the smart contract code into Remix.

   Cookbook's AI solidity co-pilot, ChefGPT, is available within the Remix plugin to answer questions about Linea, Solidity, or the smart contract you're working with.

   

4. Compile and deploy the smart contract as described in the Remix instructions.

Deploy your smart contract with Hardhat

After finding the smart contract or protocol you want to work with in Cookbook, select the Download Source option and select Hardhat to download the contract boilerplate. For this example, we'll use Cookbook's Simple ERC-20 Token Smart Contract.

Compile the smart contract

In the project folder, install the required packages and dependencies:

npm install

Then, compile the smart contract:

npx hardhat compile

Add arguments to the constructorArgs array in the deploy.js file in the scripts folder and save. If you do not need any arguments, leave the array empty.

Deploy the smart contract

Linea Sepolia

1. In your .env file, add your Infura Linea API key and add your wallet private key.

   INFURA_API_KEY_LINEA_SEPOLIA = "<YOUR API KEY HERE>"
   WALLET_PRIVATE_KEY = "<YOUR PRIVATE KEY HERE>"

2. In the hardhat.config.js file, add the following lines:

   const INFURA_API_KEY_LINEA_SEPOLIA = process.env.INFURA_API_KEY_LINEA;

   lineaSepolia: {
   url: `https://linea-sepolia.io/v3/${INFURA_API_KEY_LINEA}`,
   accounts: [PRIVATE_KEY],
   },

3. In the hardhat.config.js file, uncomment the following line:

   const PRIVATE_KEY = process.env.PRIVATE_KEY;

4. Deploy the smart contract to the Linea Sepolia testnet

npx hardhat run --network (lineaSepolia) scripts/deploy.js

Hardhat will return the deployed smart contract address in your terminal. View and verify your smart contract on the Linea Sepolia block explorer.

Mainnet

1. In your .env file, add your Infura Linea API key and add your wallet private key.

   INFURA_API_KEY_LINEA = "<YOUR API KEY HERE>"
   WALLET_PRIVATE_KEY = "<YOUR PRIVATE KEY HERE>"

2. In the hardhat.config.js file, add the following lines:

   const INFURA_API_KEY_LINEA = process.env.INFURA_API_KEY_LINEA;

   linea: {
   url: `https://linea-mainnet.io/v3/${INFURA_API_KEY_LINEA}`,
   accounts: [PRIVATE_KEY],
   },

3. In the hardhat.config.js file, uncomment the following line:

   const PRIVATE_KEY = process.env.PRIVATE_KEY;

4. Deploy the smart contract to the Linea Mainnet:

npx hardhat run --network (linea) scripts/deploy.js

Hardhat will return the deployed smart contract address in your terminal. View and verify your smart contract on the Linea Mainnet block explorer.

Deploy your smart contract with Foundry

After finding the smart contract or protocol you want to work with in Cookbook, select the Download Source option and select Foundry to download the contract boilerplate. For this example, we'll use Cookbook's Simple ERC-20 Token Smart Contract.

Prerequisites:

• Install Rust.
• Install Foundry.

1. In the project directory, build the contracts:

   forge build

   If you encounter a "stack too deep" error, try running the following command instead

   forge build --via

2. In the scripts directory, uncomment all the code in the contract.s.sol file. Replace "ARG1", "ARG2", 2000 with your Token Name, Token Symbol and desired Token Quantity where you see the code below:

   FixedToken _contract = new FixedToken("ARG1", "ARG2", 2000);

3. Update the .env file with your Linea RPC URL, followed by your MetaMask wallet private key and your Etherscan API key token values.

   note

   The example uses Sepolia, but you can update it to use Mainnet instead.

4. Run the command to define your environment variables globally:

   source .env

5. Deploy your contracts:

   forge script script/contract.s.sol:ContractScript --rpc-url $SEPOLIA_RPC_URL --broadcast --verify -vvvv
   note

   If using Mainnet, then update the --rpc-url accordingly with the variable in the .env file.

Your contract will be verified on the Linea Sepolia explorer automatically upon deployment. You can manage and interact with your newly deployed smart contract in the Linea Sepolia block explorer.

note

The tests in the contract.t.sol file are only examples, please generate your own.
