Solidity devs, need your help confirming something: 

Let’s say I have 100 ERC721 tokens that have a custom uint8 state, and I want to update that state by -1 for all tokens at once. Would you:

A. Loop over in the contract with high gas estimation 

B. Loop on the client sending lots of smaller transactions

Transaction has a 21k gas overhead so doing it in the contract would be cheaper since you just pay the 21k gas overhead once

Looping in the contract would be cheaper, though be aware of the block gas limit, if your gas used exceeds that, it won't get included in a block regardless of priority fees except the block gas limit is increased in the future

Interesting, what about scaling? Like if I wanted to keep minting NFTs and eventually get to something crazy like 10k? Not saying that’s the plan but trying to think ahead
