Crate kobe_btc 

Bitcoin HD wallet derivation for Kobe.

Derives Bitcoin addresses from a kobe_primitives::Wallet seed following BIP-32/44/49/84/86. Supports P2PKH, P2SH-P2WPKH, P2WPKH, and P2TR across mainnet and testnet.

Architecture

• Key derivation: kobe_primitives::Wallet::derive_secp256k1 (shared pipeline).
• Address and WIF: implemented in this crate and pinned by KATs (BIP-44/49/84/86; BIP-49 testnet official vectors; bitcoinjs-lib where noted).
• The workspace prefers thin wrappers around mature libraries; kobe-btc intentionally drops the bitcoin crate dependency while keeping the same derived address strings and WIF encoding.

Taproot scope

Supported: single-key, key-path-only P2TR (BIP-86 style). Not supported: script trees, merkle roots, MuSig, signing, or spending. Internal keys use BIP-340 lift_x (even-y). The witness program is the x-coordinate of the tweaked output key Q; addresses match BIP-86 KATs.
