 ## Local Verification
-
+ 
 Run the focused contract test suite from the workspace root:
-
+ 
 ```sh
 cargo test -p predictify-hybrid
 ```
 
+### WASM Size Budget
+The compiled WASM size is monitored in CI to avoid excessive deployment fees. 
+The default budget is 96 KiB. You can override this by setting the `WASM_SIZE_BUDGET` environment variable (in bytes).
+To check the size locally:
+```sh
+bash scripts/check_wasm_size.sh
+```
+
 If you are auditing or upgrading dependencies, regenerate the lockfile and rerun the package tests after any workspace dependency change.
