hi guys, how does a token erc20 works? I mean, each token is smart contract with the standard (interface) for ERC20?

so supposing we have an erc20 token called ZZZ, 1 ZZZ is represented as a smart contract on the ethereum chain where the owner of the contract is my address?

the owner of every token recorded in erc20-smart contract

not just you

I dont get It sorry

The erc20 has the owner function as well

erc20 is a contract that have records which address have amount token. for first first only deployer address will have amount as much as total supply

btw for standart erc20 token there is no one own the contract

Ok so basically when i deploy the contract ad erc20 i own the whole max supply as balance. If i pass 10 token to another address It Will have a 10 coins in its balance Right? So basically the whole deployed sc erc20 is the only One Who is deployed and keeps tracks of all' the transactions and balances?

👍

And i can query It asking the balances of everyone?

So the owner of the contract (erc20) is the First deployer?

q1: yes q2: its depend, you may save deployer address as variable named "owner" in erc20, not a standard in erc20. you may use the address for something unique, ex: send some token to "owner" address when there is transaction - of course it is not standard

Ok, but for being an erc20 the code must ne standard or i can change It with further features

its up to you, if your community accept that feature, why not. btw source code must be opened so other can see there is no malicious code

to be accepted on exchange the token must have minimal erc20 interface, you may add some function/feature without change/remove erc20 function

Ok

And what about erc721?

cryptokitties

Yes i knoe

But i mean they are non fungible

So the interface is different? They do not Need the max supply ?

they are different. erc721 not erc20+some features

why they are different?

erc20 => money erc721 => things

in erc721 there is again just a single SC? it shoudl change since objects/things can change among owners

yes, erc721 just a single sc. its record uniqueid paired to address, not like erc20 thats record amount paired to address

and the uniqueid is the single object/thing related t that address?

yes

what a time to be alive !! hahaha

thanks man
