I’m new to smart contract development and was wondering what parts of OpenZeppelin are free to use. I’m currently going through the upgradeable smart contract tutorial with Hardhat and was wondering if this is free in production or just the testnet. What other aspects are paid/free?
I think current productions have:
OpenZeppelin/openzeppelin-contracts which is a library for secure smart contract development.
OpenZeppelin/openzeppelin-contracts-upgradeable which is upgradeable variant of OpenZeppelin Contracts, meant for use in upgradeable contracts.
OpenZeppelin | Defender which is a platform to automate Ethereum operations and deliver high-quality products faster.
OpenZeppelin | OpenZeppelin Contracts Wizard which is an interface to interactively build a contract out of components from OpenZeppelin Contracts
OpenZeppelin | Ethernaut Which is a Web3/Solidity based wargame played in Ethereum where each level is a smart contract that needs to be hacked.
And almost all are free. I only know asking OpenZeppelin to audit contracts needs to pay.
Great, thanks a lot!
Defender is free for individuals.
