## Why do I get "transaction failed" error? 

If you are using Nami, it is very likely that you have not set a collateral amount; for more info, see [this article](https://docs.cardano.org/plutus/collateral-mechanism).

You can also follow these steps to fix the issue.

* Click on your wallet icon, then select "Collateral".
