This is a collection of smart-contracts that help you to launch your own 10k-avatar collection like CryptoPunks, Bored Ape Yacht Club or Pudgy Penguins.

Made by https://buildship.xyz. If you can't code, use our simple web-app to deploy!

USE AT YOUR OWN RISK. Most of the features are in production already, however this doesn't guarantee any security. Unreleased and speculative code is located in contracts/experiments directory.

Features include:

ERC721CommunityImplementation.sol

• Manually start/stop sale
• Reserve X tokens for team or community
• Deployed by Factory using Clones
• Supports NFTExtension to upgrade mint and tokenURI functions

ERC721CommunityBase.sol

• Same features as ERC721CommunityImplementation
• Import and inherit in your own projects

contract MyPFPNFT is ERC721CommunityBase {

    constructor() ERC721CommunityBase(
        0.1 ether, // public mint price, you can change later
        10000, // total supply
        100, // reserved
        20, // max mint per transaction
        0, // royalty fee
        "ipfs://Qm/", // baseURI
        "Bored Ape Yacht Club", 
        "BAYC",
        false // should start at 1 or at 0?
    ) {}

}

Init

npm i
touch .mnemonic
node scripts/generate_mnemonic.mjs
vim .mnemonic # input generated mnemonic

cp .env.example .env
vim .env # input your keys

Development

When you change something, run:

npx hardhat compile

Then, to test your code:

npx hardhat test

Checking different versions of ERC721CommunityImplementation:

colordiff contracts/ERC721CommunityBase.sol contracts/ERC721CommunityImplementation.sol --context=1
colordiff contracts/ERC721CommunityBase_ERC1155.sol contracts/ERC721CommunityBase.sol --context=1

Deploy to production

You can deploy using Hardhat. Refer to Hardhat scripts and console guides for deployment. https://hardhat.org/guides/deploying.html

However, we also support deploying with your Metamask:

Upload to IPFS for Frontend Deploy

Instead of deploying from your local machine, you can compile and send it for deployment from the Buildship web app.

hh upload contracts/Greeter.sol --args '"hello","bar"'

It needs network selection to run, but it doesn't matter which you use. You can run with development network.

In the end, you get IPFS hash to the uploaded bytecode. Use in on https://gate-rinkeby.buildship.xyz/deploy/bafkreid4l4ru7sngq6fcvpizljo7hpm6dmcwjory4kcrbpbkde2xih75au?args=[]
