Right now Hedgehog is specific to the Ethereum account model (eg. POA network and others use this too), but there's no reason the approach couldn't be extended to work with other chains. Here's the key section of code that makes this Ethereum-specific: https://github.com/AudiusProject/hedgehog/blob/master/src/authentication.js#L28 https://github.com/AudiusProject/hedgehog/blob/master/src/au... You could replace the use of 'ethereumjs-wallet/hdkey' with any other chain wallet library if it is compatible with the BIP-39 style HDWallet structure. Bitcoin and many other blockchains have compatible libraries that could be substituted easily!
