+# SOL / WSOL Operations
+
+[中文](README_CN.md)
+
+Demonstrates wrapping SOL, partially unwrapping WSOL through the SDK seed account, and closing the WSOL account to recover the remaining SOL.
+
+> All three steps submit real transactions. Set `PRIVATE_KEY` and RPC, use a test wallet first, and reduce amounts as appropriate.
+
+```bash
+cargo run --package wsol_wrapper
+```
+
+Closing WSOL unwraps the account's full remaining balance and removes the account. Do not run that step when another workflow expects the same WSOL account to remain available.
