Thirdweb changing return type of wagmi useAccount hook

When implementing Thirdweb into my Next.js app, I had noticed unusual type errors. They were about type string not being assignable to type Address (0x${string}).
I checked the type of the address I was getting from wagmi's useAccount hook and it was returning string | uindefined which was not the case before.

After removing the <ThirdwebProvider> from my app it was back to returning the correct types.

I have not used thirdweb before, however, I am positive that this is not the intended behaviour, since the address should maintain the type set by wagmi & viem to maintain type safety. Many web3 libraries do support the Address type therefore I am unable to implement thirdweb into my application, and converting every instance of useAccount instance that returns the address top the Address type is not desired.

Package versions

Wagmi version: 2.14.16
viem cersion: 2.27.3
@thirdweb-dev/wagmi-adapter version: 0.2.58
thirdweb version: 5.95.2

TOOL-4226 Thirdweb changing return type of wagmi useAccount hook

@encryptedDegen

hi @encryptedDegen - thirdweb does use the option to override the internal types of AbiType

declare module "abitype" {
  export interface Register {
    AddressType: string;
  }
}

You can learn about that configuration here: https://abitype.dev/config

In the short term you should be able to add a similar declaration into your own app to do the opposite:

declare module "abitype" {
  export interface Register {
    AddressType: `0x${string}`;
  }
}

In the longer term we may re-visit this, but it would likely have to come with a major version bump to thirdweb.

-- Edit

Not closing this issue because it is useful to track the need / requirements for more/less strict types.
