Interface Pattern for Wallet

Motivation

current wallet use 0x1::coin::transfer to transfer tokens, but how about a token with custom transfer

maybe we need some interface like ERC20

account::module::balance_of(address)
account::module::transfer

[dulumao]

No interface, import module source

[babyface001]

@dulumao I mean for client side.

wallet app. token interface.

[babyface001]

@dulumao I want a coin with custom transfer, but I can not override 0x1::coin::transfer, and wallet only call 0x1::coin::transfer to transfer, so my coin not work.

interface just a convention that a module should has some functions.

[babyface001]

for example.

module Token::erc20 {
    public entry fun transfer(){
        // interface override.
        // your logic or just call 0x::coin::transfer
    }
}

[babyface001]

maybe move should have some primitive like trait

someone get in touch in upstream https://github.com/move-language/move/issues/449

[davidiw]

Yeah, this is a Move feature, not an Aptos, it'd be better to have that conversation upstream for now :).
