## Abstract

An simple extension to ERC-20 fungible tokens that provides a standard method to expose metadata through the addition of an `uri()` function.

## Motivation

ERC-20 tokens are the most popular interface for digital assets. They typically are exchanged under branded icon images or other information that users might otherwise associate with "non-fungible" or NFT assets. This standard proposes a simple extension to be adopted by otherwise ERC-20-compliant tokens to expose this additional metadata onchain.

## Specification

One new function is defined by the ERC-7683 token metadata interface:

```solidity=
function uri(uint256) external view returns (string memory);
```
