How many (or up to how many) characters does a Ethereum address have?
I have been looking online for an answer but it seemed harder to find than I expected.
I am working on storing a list of Ethereum addresses with
web3.js in a MySQL database, and need to know the limit of characters I should put for the VARCHAR. I could ofcourse put a very high value like 100 and be safe from not having enough space, however that would cost some speed.
