ERC-1175 : Wallets and Shops standard for safe pay

[Nitro888]

All Tokens go to heaven

Simple Summary

Make wallets and shops created from certified contracts make erc20 tokens easy to use for commerce.

Abstract

The mutual trust between the wallet and the shop created by the authenticated contract allows you to pay for and purchase items at a simple process.

Motivation

New standards with improvements have been released, but the majority of tokens currently being developed are erc20 tokens. So I felt I needed a proposal to use old tokens in commerce.
To use various erc20 tokens for trading, you need a custom contract. However, a single wallet with a variety of tokens, and a mutually trusted store, can make transactions that are simple and efficient. The erc20 token is traded through two calls, approve (address _spender, uint256 _value) and transferFrom (address _from, address _to, uint256 _value), but when using the wallet contract, paySafe (address _shop, uint256 _item)will be traded only in one call.
And if you only reuse the store interface, you can also trade using payUnsafe (address _shop, uint256 _item).
