## PR-Codex overview
This PR focuses on enhancing the `thirdweb` SDK by gracefully handling cases where a wallet does not provide a chain ID during connection, ensuring better compatibility with certain wallets.

### Detailed summary
- Updated the logic in `fromEip1193Provider` to check for `undefined` chain IDs.
- Added a test to verify connection handling when no chain ID is provided.
