A guided design and implementation of a HD wallet in Go with a convenient CLI for easy experimentation using Nushell (or any other shell). The wallet CLI exposes an easy to use and experiment CLI tools to generate BIP-39 mnemonics for a HD wallet, derive extended private and public keys for a BIP-32 HD wallet, encode and decode derived keys into different formats e.g. xprv, xpub. The wallet CLI also provides tools to generate secp256k1 key pairs, ESDSA sign transactions and verify signatures. The wallet CLI exposes tools to encode and decode data using the bsae58 and base58check encoding, as well as encode an Ethereum address using the ERC-55 address encoding.
