What does "failed to execute the unsigned transaction" error mean?

This error occurs due to a limitation in zkEVM, a technology used in blockchain networks. The issue arises when there are too many operations or zk resources within zkEVM. In particular, when the number of actions, known as multicalls, goes beyond 195, it can use up all the available zk resources, leading to transaction failures.

To address this error, it's important to optimize the number of multicalls and reduce how often they are used. By doing this, you can prevent excessive resource consumption, avoid encountering this limitation, and ensure that your transactions run smoothly.
