*A New Advanced Token Standard for Ethereum*

This standard defines a new way to interact with a Token Contract. This standard takes advantage of [ERC820](https://github.com/ethereum/EIPs/issues/820).

## Proposal

The official proposal can be found at: [eips.ethereum.org/EIPS/eip-777](https://eips.ethereum.org/EIPS/eip-777).

The original submission with discussion can be found at: [ethereum/eips/issues#777](https://github.com/ethereum/eips/issues/777) (initial pull request: [ethereum/eips/issues#907](https://github.com/ethereum/eips/issues/907)).

> You can suggest improvements to the **reference implementation** by submitting pull requests to this repository with modifications to [`eip-777.md`](eip-777.md).

>

> For suggestions related to the **standard**, please comment on the original submission at: [ethereum/eips/issues#777](https://github.com/ethereum/eips/issues/777)

## Specification

A copy of the specification can be found in this repository at [`eip-777.md`](eip-777.md).

## Reference Implementation

The reference implementation is available at: [contracts/examples/ReferenceToken.sol](contracts/examples/ReferenceToken.sol)

This repository including the specification and the reference implementation can be installed via `npm` with:

``` bash

npm install erc777

```

## Logo

> The logo MUST NOT be used to advertise, promote or associate in any way technology – such as tokens – which is not ERC777 compliant.

The official logo for the standard can be found in the official EIPs repository at: [/ethereum/EIPs/assets/eip-777/logo](https://github.com/ethereum/EIPs/tree/master/assets/eip-777/logo).  

Copies of the logo are provided here as well as a courtesy and can be found in the [logo](./logo) folder in [svg](logo/svg) and [png](logo/png) formats.
