How to get total supply of a token

[0x-j]

Asked by waynebruce on discord dev-discussion

does aptos have a generic way of fetching the total supply of tokens deployed on the network? akin to erc20.totalSupply() on evm? If so, is anyone able to point me to some documentation? From looking at the explorer, it seems that this isnt possible since more than one token can exist at one address

There are 2 ERC-20 like token standards on Aptos: Coin (old) and Fungible Asset.

Here's an example of getting coin total supply.

Here's an example of getting fungible asset total supply.
