Pre-flight checklist

• I have read the Contributing Guidelines on pull requests.
• Commit messages follow the conventional commits spec
• If this is a code change: I have written unit tests.
• If this changes code in a published package: I have run pnpm changeset to create a changeset JSON document appropriate for this change.
• If this is a new API or substantial change: the PR has an accompanying issue (closes #0000) and the maintainers have approved on my working plan.

Motivation

Fixes the issue reported by the community of interface misalignment

Type 'JsonRpcProvider' is not assignable to type 'Provider'.
  The types returned by 'callFunction(...)' are incompatible between these types.
    Type 'Promise<T | undefined>' is not assignable to type 'Promise<T>'.
      Type 'T | undefined' is not assignable to type 'T'.
        'T' could be instantiated with an arbitrary type which could be unrelated to 'T | undefined'.
