scalecodec comes with requests as a dependency

[damascene]

bip_utils doesn't connect to network however scalecodec which is related to Palkdot is installing requests library. It's included in requirements.txt

Hopefully there would be a way to make scalecodec as an optional dependency. Seems like bip_utils comes with about 20 dependencies. Would you consider documenting which libraries is needed for which functionality.

thank you.

Hi, the list of dependencies is listed at the beginning of the readme with the related explanation:

• crcmod for CRC computation
• pycryptodome for cryptographic functions
• coincurve for secp256k1 curve
• ecdsa for nist256p1 and secp256k1 curves
• ed25519-blake2b for ed25519-blake2b curve
• pynacl for ed25519 curve
• py-sr25519-bindings for sr25519 curve
• scalecodec for SCALE encoding

I don't think there is anything useless. Beside scalecodec, it's all stuff needed for cryptography. I implemented most of the stuff by myself just to minimize the usage of external libraries (e.g. base58, bech32, ss58, all the mnemonic parts). Anyway, yes I could implement the SCALE encoding by myself as well, since I only need a small subset of it. I'll consider doing it.
