ERC721 NFT Token Tutorial with Truffle and OpenZeppelin (2021)

Aisthisi

In this video we are producing an NFT using the OpenZeppelin ERC721PresetMinterPauserAutoId

We setup truffle, we install the openzeppelin Smart Contracts and use ERC721PresetMinterPauserAutoId to generate our Token.

Then we override the tokens functionality with _beforeTokenTransfer and put in our own token locking mechanism.

Then we use the Truffle Developer console to test our tokens and mint, transfer and unlock Tokens manually.

After that we write Unit Tests for the Token Contract.
