**kobe** is a minimal, `no_std`-compatible Rust library for HD wallet derivation across multiple blockchain networks. It provides a unified interface for BIP39 mnemonic management and chain-specific address generation.
## Features
- **Multi-chain support** — Bitcoin (P2PKH, P2SH, P2WPKH, P2TR), Ethereum, Solana
- **HD derivation** — BIP32, BIP39, BIP44, SLIP-10
- **Multiple derivation styles** — Standard, Ledger Live, Ledger Legacy, Trust Wallet
- **`no_std` compatible** — Suitable for embedded and WASM targets
- **Zeroizing** — Sensitive key material is zeroized on drop
## Security
This library has **not** been independently audited. Use at your own risk.
Key material handling:
- Private keys use `zeroize` for secure memory cleanup
- No key material is logged or persisted by the library
- Random generation uses OS-provided CSPRNG via `rand_core::OsRng`
