Simple Counter Contract

A simple smart contract built with Foundry for learning and testing purposes.

Features

• Basic counter functionality with increment and set operations
• Deployed using Foundry scripts

Prerequisites

• Foundry installed

Setup

1. Clone and navigate to the project:

cd simple-contract-test

2. Install dependencies:

forge install

3. Create environment file:

cp .env.example .env

4. Edit .env file and add your private key:

PRIVATE_KEY=your_private_key_here

Deployment

Quick Deploy

./deploy.sh monad_testnet

Manual Deploy

# Dry run (simulation)
forge script script/Counter.s.sol --rpc-url monad_testnet

# Deploy to Monad Testnet (verification done separately with Sourcify)
forge script script/Counter.s.sol \
    --rpc-url monad_testnet \
    --private-key $PRIVATE_KEY \
    --broadcast

# Deploy to other networks with auto-verification
forge script script/Counter.s.sol \
    --rpc-url sepolia \
    --private-key $PRIVATE_KEY \
    --broadcast \
    --verify

Verification

Sourcify Verification (for Monad Testnet)

For Monad Testnet, use Sourcify for contract verification:

./verify-sourcify.sh [contract_address] monad_testnet

Example:

./verify-sourcify.sh 0x123...abc monad_testnet

Traditional Block Explorer Verification

For other networks with automatic verification:

./verify.sh [contract_address] [network]

Example:

./verify.sh 0x123...abc sepolia

Testing

Run the test suite:

forge test

Run tests with gas reporting:

forge test --gas-report

Supported Networks

• Monad Testnet (Chain ID: 10143) - Primary testnet

Faucets

Get test tokens from these faucets:

• Monad Testnet: Visit Monad Discord for faucet access

Verification Services

• Sourcify: https://sourcify-api-monad.blockvision.org (for Monad Testnet)
