+**Refactor createSessionKey function to remove contract parameter**
+
+- Remove `contract` input parameter from `createSessionKey` function in `thirdweb/wallets/in-app`
+- Function now recreates contract internally using `account.address` with auto-resolved ABI  
+- Updated function signature to take `client` and `chain` directly instead of extending `BaseTransactionOptions`
+- Updated related session key tests to match new function signature
+- Simplified implementation while maintaining all existing functionality
