**Kangaderoo** is a Netherlands-based open-source developer who contributes frontend tooling and example code to the [Radix](/ecosystem) community. His public [GitHub profile](https://github.com/kangaderoo) spans more than a decade of cryptocurrency development, from early mining utilities to recent work on [Scrypto](https://github.com/radixdlt/radixdlt-scrypto)-based Radix applications.

## RRC-404 frontend

Kangaderoo published the [frontend code for the RRC-404 project](https://github.com/kangaderoo/rrc-404), a Radix implementation of the ERC-404-style hybrid token standard built with Scrypto. [RRC-404](/developers/tools/rrc-404) lets a holder convert a token between fungible and non-fungible states, making otherwise-indivisible NFTs tradable as fractional, liquid assets.

## Open-source contributions

He maintains a fork of the [community-scrypto-examples](https://github.com/radixdlt/community-scrypto-examples) repository — a shared collection of reference Scrypto code — and is recognised on GitHub as an [Arctic Code Vault](https://archiveprogram.github.com/) contributor. His earlier repositories cover cryptocurrency mining tooling and pool software, reflecting a long background in blockchain infrastructure.
