Is there a maximum array size in Solidity?

Question

And if so, what is it?

Also, would it differ by dynamic and static arrays?

My initial guess is that:

a statically-declared array has a maximum number of slots equal to the largest uint, as in array[max_uint256].
a dynamically-declared array has no "practical" limit to its size (but perhaps a huge theoretical one: see link at bottom)

There are no limits in specification, so arrays may grow up to 2^256-1 elements.

It’s worth noting that even if such a large array could exist, traversing it would fail due to was constraints. – pabloruiz55 Dec 12 '17 at 1:13

@pabloruiz55, as in due to gas constraints ? – Andy B. Jul 16 '18 at 17:44

Yes, I meant GAS constraints – pabloruiz55 Jul 17 '18 at 1:38
