Contract deployment

The Wischain Sepolia Testnet enables developers to deploy smart contracts seamlessly. This tutorial will guide you through the process of deploying a contract on Wischain Sepolia using popular Ethereum development tools. We’ll demonstrate contract deployment with both Hardhat and Foundry.

Getting Testnet ETH

Before you begin deploying your contract, you’ll need to acquire test tokens. This can be done by requesting test ETH from a Sepolia faucet and utilizing the bridge to transfer the test ETH from Sepolia to Wischain Sepolia. Alternatively, you can obtain Wischain Sepolia ETH directly. For detailed instructions, refer to our Faucet and Bridge guides.

Deploying Contracts with Hardhat

1. Install Node.js and Yarn: Ensure you have Node.js and Yarn installed on your machine.

2. Clone the Repository and Install Dependencies:

   git clone https://github.com/wischain-tech/wischain-guides.git
   cd wischain-guides/contract-deploy-demo
   yarn install

3. Configure Environment Variables: Create a .env file in the root directory, using .env.example as a template. Update the PRIVATE_KEY variable with your own account's private key.

4. Compile the Contract: Execute the following command to compile your smart contract:

   yarn compile

5. Deploy the Contract: Deploy your contract to the Wischain Sepolia Testnet using:

   yarn deploy:wischainTestnet

6. Run Hardhat Tests: To run tests for your contract, use:

   yarn test

Deploying Contracts with Foundry

1. Clone the Repository:

   git clone https://github.com/wischain-tech/wischain-guides.git
   cd wischain-guides/contract-deploy-demo

2. Install Foundry:

   curl -L https://foundry.paradigm.xyz | bash
   foundryup

3. Build the Project: Use the following command to compile your project:

   forge build

4. Deploy Your Contract with Foundry: Use the following command to create and deploy your contract:

   forge create --rpc-url https://sepolia-rpc.wischain.io/ \
     --value <lock_amount> \
     --constructor-args <unlock_time> \
     --private-key <your_private_key> \
     contracts/Lock.sol:Lock

   • Replace <lock_amount> with the amount of test ETH to be locked in the contract (e.g., set a small amount like 0.00000001ether).

   • Replace <unlock_time> with a future Unix timestamp after which the funds will be available for withdrawal (e.g., 1696118400, corresponding to October 1, 2023).

   Example:

   forge create --rpc-url https://sepolia-rpc.wischain.io/ \
     --value 0.00000000002ether \
     --constructor-args 1696118400 \
     --private-key 0x...... \
     contracts/Lock.sol:Lock

By following these steps, you will successfully deploy a smart contract on the Wischain Sepolia Testnet, utilizing either Hardhat or Foundry as your development environment.
