Deploy a Crowd Funding Smart Contract to Goerli TestNet with Foundry 🚀

Prerequisites

Before you begin, ensure you have the following:

Rust installed
Foundry installed
Solidity contract (e.g., CrowdFunding.sol)

Useful Commands

Here are some useful commands to help you through the process:

Build the Contract

forge build

Test the Contract

forge test

View Detailed Test Logs and Tracebacks

forge test -vvvv

Generate Gas Report

forge test --gas-report

Deploying to Anvil

To deploy the contract to Anvil using your private key:

forge create src/CrowdFunding.sol:CrowdFunding --private-key=<private-key-from-anvil>

Deploying to Anvil using Deployment Script

Ensure you have an .env file with the PRIVATE_KEY of any Anvil account. Then:

cp .env.example .env
forge script script/CrowdFunding.s.sol --fork-url http://localhost:8545 --broadcast

Interacting with the Deployed Contract on Anvil

After deploying the contract, retrieve the contract address from the output:

export CONTRACT_ADR=<contract-address>

Set variables for ease of use:

export CAMPAIGN_OWNER_PRIV_KEY=<private-key-of-first-account-in-anvil>
export CAMPAIGN_OWNER_ADDRESS=<address-of-first-account-in-anvil>
export CAMPAIGN_DONOR_PRIV_KEY=<private-key-of-first-account-in-anvil>

Creating a Campaign

cast send $CONTRACT_ADR "createCampaign(address,string,string,uint256,uint256,string)" $CAMPAIGN_OWNER_ADDRESS "Campaign 1" "Campaign 1 Description" 10ether <current-epoch-time + 300> "https://i.kym-cdn.com/photos/images/newsfeed/002/205/307/1f7.jpg" --private-key=$CAMPAIGN_OWNER_PRIV_KEY

Note: To set the deadline, add the current Unix epoch time to the command and add 300 seconds to it.

Get Campaign Details

cast call $CONTRACT_ADR "getCampaign(uint256)(address,string,string,uint256,uint256,uint256,string)" 0

Contribute to a Campaign

cast send $CONTRACT_ADR "donateToCampaign(uint256)" 0 --value 10ether --private-key=$CAMPAIGN_DONOR_PRIV_KEY

Withdraw Funds

cast send $CONTRACT_ADR "withdraw(uint256)" 0 --private-key=$CAMPAIGN_OWNER_PRIV_KEY

Check Campaign Owner Balance

cast balance $CAMPAIGN_OWNER_ADDRESS

Deploying to Goerli TestNet

Set the following variables:

export GOERLI_URL=<goerli-url-from-infura-or-alchemy>
export PRIVATE_KEY=<private-key-from-metamask>
export ETHERSCAN_KEY=<etherscan-api-key>

Deploy the contract to Goerli along with verification:

forge create --rpc-url $GOERLI_URL --private-key $PRIVATE_KEY src/CrowdFunding.sol:CrowdFunding --etherscan-api-key $ETHERSCAN_KEY --verify

Interacting with the Contract on Goerli

You can use similar commands as above, replacing the contract address and adding --rpc-url $GOERLI_URL to the commands.

That's it! You're now equipped to deploy and interact with your Solidity contract on the Goerli TestNet using Foundry. Have fun experimenting and building on the blockchain!
