library1.1.0pypypi✓ verified 80d ago

A reference implementation of the SLIP-0010 specification that generalizes BIP-0032 hierarchical deterministic wallet derivation for curves secp256k1, NIST P-256, ed25519, and curve25519. Current version 1.1.0, stable maintenance.

Derive a hierarchical deterministic node from a seed.

from slip10 import derive_node from slip10 import BIP32Curve # BIP-32 test vector for secp256k1 seed = bytes.fromhex('000102030405060708090a0b0c0d0e0f') chain_code, private_key, public_key = derive_node( seed, path=[44 | 0x80000000, 0 | 0x80000000], curve=BIP32Curve.SECP256K1 ) print(private_key.hex()) print(public_key.hex())

Debug

Known issues

breakingIn version 1.0.0, the derive_node function did not accept the 'curve' parameter; it defaulted to secp256k1. In 1.1.0, the curve parameter is required if not using the default. Code without explicit curve may break if default changes.

fix

Always pass curve=BIP32Curve.SECP256K1 (or your desired curve) when calling derive_node.

affects: <1.0.0

gotchaThe return order from derive_node is (chain_code, private_key, public_key). Many users expect (private_key, chain_code, public_code) or similar.

fix

Unpack as: chain_code, private_key, public_key = derive_node(...).

affects: all

gotchaThe path argument uses hardened derivation with the '| 0x80000000' pattern (not apostrophe notation). Using integers without the OR may derive non-hardened keys unintentionally.

fix

Use path=[44 | 0x80000000, ...] for hardened derivation.

affects: all
