# DLT Token Standard (ERC-6960)

<mark style="color:purple;">**Enter ERC-6960.**</mark> A token standard designed by our team at Polytrade to represent Real-World Assets (RWAs) and support fractional ownership.

DLT Standard Implementation

The existing token standards lack the ability to support fractional ownership of both fungible and non-fungible tokens. While ERC-6150 is an extension of ERC-721 that standardizes an interface for the hierarchical representation of NFTs in a tree-like structure, its implementation is limited to NFTs only. This highlights the need for a more comprehensive standard that provides the same features as ERC-1155 but with added flexibility and support for hierarchical representation and fractional ownership.

If we take an invoice as an example, in a token-based economy, it can be tokenized and fractionalized for investors to own. By implementing the dual-layer token standard, a `mint` function assigns an owner to a fraction worth a certain amount by taking the following values:

* wallet address of buyer or investor&#x20;
* main Id of invoice&#x20;
* sub Id of the invoice fraction&#x20;
* amount of the invoice fraction&#x20;

**The standard can be implemented in many more cases and on many different kinds of real-world assets which reflects its flexibility and robust design.**
