• I checked there isn't already an issue for the bug I encountered.

Viem Version

2.21.45

Current Behavior

Currently the TypedDataDomain looks like this:

export type TypedDataDomain = {
  chainId?: number | undefined
  name?: string | undefined
  salt?: ResolvedRegister['bytesType']['outputs'] | undefined
  verifyingContract?: Address | undefined
  version?: string | undefined
}

Sometimes the chainId might be larger than a number, so I was wondering whether it would be possible to also support string and bigint (or maybe just string) for that field.

I have seen in another "famous library" (:p) that the type for chainId is number | bigint | string | null.

Thanks in advance.

Expected Behavior

I can pass a string as chainId. Specifically, I would like to be able to pass these values:
