Viem

@jxom is it still not possible to read/write by passing functionSelector + args / calldata with viem or wagmi? functionName is not always known

I understand type safety would be lost, but I'd love to stop depending on ethers due to this

good to know! but does it also work if the abi doesn’t have the selector?

in my case I need to call a function with the same params, but with variable selector. would be great if I could preserve type safety, but I’m aware it’s an unusual scenario so would be happy with directly passing the calldata

Makes sense! Can take a look this weekend to widen the type.

You can workaround for now by doing:

const hash = client.readContract({
  address: '0x...',
  abi,
  functionName: '0xdeadbeef' as any
})

This should work as internally our ABI Function encoding/decoding utils accept selectors as names.
