Opensea MetaTransactions

Hello my friends. I'm making my very first ERC-721 project and I'd love to mint it in polygon, so I can use gas-less transactions in opensea.

I have very basic html and js knowledge, but I managed to create a smart contract using remix.

I just saw the workshop "Gasless MetaTransactions with OpenZeppelin Defender" and I'm not sure if I'll be able to implement it.

Is it possible to implement the meta transactions only using remix?

Thank you so much!

Hi @Aleix_Iglesias1! I think it's possible, but I wouldn't advice it. Remix is designed as an occasional playground, so any work that you mean for the long term is better suited for more stable development environment: a local IDE (Visual Studio Code, Sublime, IntelliJ, etc), an Ethereum dev env (Hardhat, Truffle), versioning (git).

I recommend following our learning guides from scratch:

Hope this helps!
