Package Exports

erc-payable-token/test/introspection/SupportsInterface.behavior
erc-payable-token/test/token/ERC1363/ERC1363.behaviour

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (erc-payable-token) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

ERC-1363 Payable Token

This is an implementation of the ERC-1363 Payable Token that defines a Payable Token, a Token Receiver and a Token Spender.

The ERC-1363 is an ERC-20 compatible token that can make a callback on the receiver contract to notify token transfers or token approvals. It can be used to create a token payable crowdsale, selling services for tokens, paying invoices, making subscriptions, use them for a specific utility and many other purposes.

This proposal allows to implement an ERC-20 token that can be used for payments (like the payable keyword does for Ethereum).

Install

npm install erc-payable-token

Usage

pragma solidity ^0.5.5;

import "erc-payable-token/contracts/token/ERC1363/ERC1363.sol";
