@Keyrxng
I am writing test cases to claim gift cards, but I encountered a roadblock. This script (vitest/web3.ts) contains the creation of an Anvil child process, generating demo permits, and transferring tokens to the gift card treasury address. When I try to call permitTransferFrom to transfer the tokens, I get an InvalidSigner error.
Shouldn't I be able to claim the tokens with Anvil account [0]?

@EresDev would know better for this particular task, but yeah I assume so looking at the script but various other factors might have changed so I'm unsure personally.

When I try to call permitTransferFrom to transfer the tokens, I get an InvalidSigner error.

Maybe because this is missing networkId in permit parameters?

const tx = await permit2Contract.permitTransferFrom(

Plus, I also think it needs token approval and a few other steps. Something similar to what happens in yarn test:fund command.

Is it worth having all this anvil setup in backend unit tests? It is already present in e2e tests. Did you consider just mocking the blockchain? I think it is worth considering mocking the blockchain. In fact, we don't even change the state of blockchian in the backend, and it can make things much simpler.
