Find below some transaction reviews and how you can improve them for your users. ## Risky approval of your funds This transaction review means that some of the assets that are approved are not spent in the same transaction. On Starknet, [multiple calls can be bundled in a single transaction](https://docs.argent.xyz/aa-use-cases/multicalls) which means that open approvals are often avoidable. Make sure to spend 100% of the approved amounts in the same transaction. If you have a specific use case that requires open approvals, please reach-out to us so we can figure out how handle the warning.
