# QNEKT [Qnekt](https://github.com/earlgreytech/metamask-extension) is a fork of Metamask * Since Qtum is a fork of Bitcoin and uses UTXOs, transaction signing is completely different from Ethereum. * Because of that, it is not possible to just add [Janus](https://docs.qtum.site/en/part3/part3/part3/part3/part3/part3/part2/janus.md) as a remote endpoint in Metamask and have everything just work. * For a more technical understanding, see [Why the need to fork Metama](https://docs.qtum.site/en/part3/part3/part3/part3/part3/part3/part3/why-qnekt.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
