Deploy a contract

Prerequisites​

  • A wallet with some testnet ETH on Horizen Testnet

Deploy a contract using Foundry​

Foundry is a Rust-based toolset for Ethereum development that helps developers manage dependencies, compile projects, run tests, deploy contracts, and interact with blockchains via the command line interface. Open a terminal and run the following commands to install Foundry:

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

Next we will create a project with Foundry. We will start with the basic Counter contract Foundry provides. Run the following command to create a Foundry project:

forge init hello_horizen && cd hello_horizen

After this we will compile our smart contracts using the following command:

forge build

Next we will deploy the counter contract located at src/Counter.sol using the forge create command. We would also need the RPC_URL and the PRIVATE_KEY of the funded wallet to deploy the contracts. Use the following command to deploy your contracts:

forge create src/Counter.sol:Counter \
--rpc-url https://horizen-rpc-testnet.appchain.base.org \
--private-key <YOUR_PRIVATE_KEY>
