# Resource Optimization

> Reducing fees and budget consumption.

Soroban has strict resource limits. Optimizing your contract ensures it remains cheap and reliable.

## Finding Hotspots

Use `prism profile <hash>` to identify the most expensive host functions in your transaction.

### Common Hotspots

* **Storage Reads**: Frequent `get_ledger_entry` calls can quickly consume the budget.
* **Deep Invocations**: Cross-contract calls add stack depth and context overhead.
* **WASM Size**: Large contract binaries increase the CPU cost of the initial load.

## Verification

After optimizing, use `prism whatif` to re-simulate the transaction with your new contract version to verify the budget reduction before redeploying.
