We loose the actual error cause here. it is a deserialization error but the message is lost and potentially mapped to a wrong invalid type. The user of this does not know that you are going to do that and I could pass in invalid to be ConnectionError and now anyone debugging this would never know what kind of error this was

This will propagate a Casper APIError to the contract runtime. I did not write any of the code in detail.rs and it was used by Casper Labs in the cep standards.

It MIGHT be propagated to ApiError, but it does not have to - depending of what called will do with error. So far I am not worried about losing error details, but rather about this error not being used in the code at all - is arguments handling done properly?

What do you mean by "is argument handling done properly"?

Let's not add back x86_64-darwin.
aarch64-darwin is enough

Will be addressed in other PR as discussed.
Bincode was unnecessarily included with default features, so it included panic handlers from `std`. It is better to make contract a `no_std`, so it's smaller. For such case, panic handlers can be registered with `no-std-helpers` feature in `casper-contract`.
For now we can stick to unstable one, to avoid heavy CI/CD.
Final demo contract suggestions.

This deposit smart contract targets the release branch of the official casper node repository, e.g. casper-network/release-1.5.6.
Contract types were introduced to write a serialized Deposit to the contract's event storage.
