[BUG]: `stablepay-sdk` README documents an unrelated thirdweb app instead of the actual SDK API

[sach2004]

Bug Description

The stablepay-sdk/README.md file currently starts as StablePay SDK documentation, but the actual body documents a completely different thirdweb + Supabase application rather than the widget SDK that exists in this repository.

This creates a real integration problem for contributors and consumers because the published package docs do not explain the actual SDK API, configuration shape, widget usage, or supported flows.

Why this is a problem:

• package consumers get incorrect setup instructions
• the README does not document Config, NetworkSelector, Widget, or transaction callbacks
• the docs point users toward unrelated technologies and architecture

Steps to Reproduce

1. Open stablepay-sdk/README.md
2. Read the title and opening lines, which suggest this is SDK documentation
3. Continue reading the body
4. Observe that the content documents a separate thirdweb/Supabase app, including unrelated stack details, APIs, authentication flow, and app architecture

Logs and Screenshots

No runtime logs apply.

The issue is a documentation mismatch in source control:

• the README file under stablepay-sdk/ does not match the code and package API in stablepay-sdk/src/

Environment Details

• Area: stablepay-sdk
• File: stablepay-sdk/README.md
• Reproducible from current source checkout on March 27, 2026
• Affects contributors and integrators reading package documentation
