I know people are trading tokens, putting them on exchanges to sell into either BTC, Ethereum or fiat. However, are there any examples of projects setting up online stores where these tokens can be directly spent on goods or services? It seems that using Metamask there ought to be a standard interface somewhere for these kinds of transactions.
Don't know why you do talk about metamask on this one yet we do know the functionality of it and since you do talk about merchants or projects that do have this kind of idea then I would say I didn't see much of those projects do succeed into this matter where having a store that do accepts erc20 tokens.I do rather believe that merchants do focuses out on Bitcoin itself since they do know its reputation when it comes to value than on erc20 which are most shitty tokens or doesn't have really use at all.
