Initial configuration verifier implementation #322

I think you can bring the RateLimit checks down by quite a lot:
-
Solana uses u64 to store this value so this check will never trigger even if capacity is at its maximum value
-
I think it's safe to say that both of these cases would count as "disabled". If the rate limit is set to be the maximum possible integer value, there is no rate limit
-
I wonder if we would add another check that's in the range of 2^32 or even smaller? To me that would still be very high for e.g. a 24h period

Yeah! Good ideas. I'm unsure if the rateLimit has values that are trimmed or not. I'll confirm this.
The 'delay' check is good! I'll add that in.

I think this should read 'greater than or equal to' given that we're using 86400 which is exactly 24 hours.

So if .locking is undefined this should be equal to 1? Is this used more like a boolean/enum for the mode of a contract or does this represent a count similar to your burn and lock variables below?
I think the comment here could be amended to mention what the 'later use' is

| managerData['threshold'] = managerConfig['threshold'].valueOf() // The 'threshold' value | ||

It would be helpful to add a note here that this is the "wormhole chain ID" for Solana.

So consistencyLevel: 1 means finalized?

Any chance you could log something here? Having a silent try-catch might hide some important errors

Could you add a note here as to why the 'chain specific code' below is being skipped in this case?

IMO this is a nice check, especially since you flag it as a warning rather than an error.

Isn't it possible to do only a mint-and-burn model without a locking chain? I thought this was part of the architecture at least at a certain point of the design discussions.
It might be good to add a check for this. If you don't want to complicate this PR then maybe we could add it as an Issue

I think it's worth a comment here that the 0x prefix is being added for convenience to allow comparing Solana/Eth with the same functions.
It looks a little strange to see Solana addresses with a 0x in front since these aren't used in the ecosystem (and in fact program addresses are not hex-encoded but use base58).
The goal with this code is to find bugs in deployed NTT tokens. Right now, it has the following capabilities:
Going forward, I want to make this more portable within a Docker container.
