Use Foundry to Deploy Smart Contracts

Foundry is a fast, portable, and modular toolkit for EVM application development written in Rust. The two main components that you'll generally be using for smart contract development are:

• Forge: used to compile, test, and deploy contracts
• Cast: used to make RPC calls to interact with a network

Prerequisite

• Wallet with sufficient balance
• The right information on the network

Install Foundry

Foundryup is the Foundry toolchain installer. Open your terminal and run the following command:

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

For more installation instructions, check here.

Create a project

1. Create a new Foundry project and install the necessary dependencies.

   forge init hello_mantle

2. Please put your contract in the src folder. For this tutorial, we will use the existing example contract Counter.sol. Then use the following command to compile a smart contract.

   forge build

   Sample Outputs

   [⠒] Compiling...
   [⠒] Compiling 24 files with 0.8.15
   [⠢] Solc 0.8.15 finished in 2.52sCompiler run successful!
   [⠆] Solc 0.8.15 finished in 2.52s

Deploy your contract

Upon successful compilation, use the following command to deploy a smart contract (replace <your-private-key> on the command line with your wallet private key).

forge create --rpc-url <mantle_rpc_url> --private-key <your-private-key> src/Counter.sol:Counter --legacy
