Allowance, approval and permit hooks

[smakosh]

Hi everyone, this is my first discussion on this repository, really grateful for what you've built here!

As I was working on implementing allowance, approvals and permits, I found myself re-using lots of useRead/WriteContract hooks and I've been thinking why not provide hooks to make this much easier?

Example:

Happy to work on this and raise a PR if this seems interesting to the community.

@smakosh do you have an implementation for this you can share ?

[smakosh]

It is on Diagonal demo, should be open sourced soon. Will have something ready before that.

[sarinniural]

@smakosh ok I will be waiting 😅

[nfts2me]

@smakosh I am also interested in these hooks!

First preview of a working useAllowance hook

[Markkos89]

looking forward to this!

[smakosh]

Initial PR that adds useAllowance here: #1136

More hooks to be followed.

[smakosh]

thinking of having these hooks in a fork of wagmi over at: https://github.com/smakosh/wagmi-hooks, as there's no intent to have these hooks in wagmi but to provide the functionality through a CLI gen.

Sounds great. You are welcome to add those to awesome-wagmi!

ERC20Permit (eip2612) is a great way to avoid the Approve + Transfer pattern which requires too much gas so having something to trigger the signature + call the contract transfer function would be great !

It might make sense to also integrate permit2 if not already

[DeveloperTheExplorer]

YES! After moving to Wagmi on Viem (instead of ethers) now it seems that there is no way to use the UniSwap Permit2 SDK...

Made a small library for handling permits with wagmi and viem here: https://github.com/vacekj/wagmi-permit/

Thanks! I was looking for something exactly like this :)

Hey is this still a thing? Looks amazing.

You can use the Wagmi CLI to generate hooks/actions like this.

You can use the Wagmi CLI to generate hooks/actions like this.

I just installed the CLI and tried to run the example, but I get this error:

npx wagmi generate

✔ Validating plugins
⠧ Resolving contracts
Invalid response
- Invalid literal value, expected "OK" at 'message'

any ideas?

[tmm]

Hard to tell without seeing your Wagmi CLI config file. Are you using the Etherscan plugin? Have you added the apiKey property?

what is the state of this...?
