A high-powered wallet for holding and trading a range of crypto assets, Function(X) is an ERC-20 token that also powers a separate blockchain. Being native to different chains gives FX broad functionalities. The ERC-20 token and the native FX token are completely interchangeable and, since FX maintains a lively developer base, they are working on integrating the BTC chain and others into a single, decentralized wallet. They offer a range of DeFi utilities and frequently add new trading mechanisms for holders. In order to vote on what function Function X should add to the wallet next, you need to hold the token. Since each newadded function adds risk of code errors, FX pushes improvements slowly but steadily.
