In the scripts section, we could also implement a command to verify the deployed contracts, wdyt?

That would be a good addition yes, but I think it is out of scope for this tutorial.
We would need the APIs for ShimmerEVM and BNBTestnet blockexplorers, and add some extra config to hardhat.config.js.
What would be more suitable is adding this part later on, WDYT?

@salaheldinsoliman , are there any blockers on this? It'd be nice to publish the last part of the series :)
