NBitcoin Skill

NBitcoin provides HD wallet operations in Sorcha through the Sorcha.Wallet.Core project. The codebase wraps NBitcoin types in domain value objects (Mnemonic, DerivationPath) and uses them exclusively for BIP32/39/44 key derivation—NOT for transaction building. Actual signing uses Sorcha.Cryptography (ED25519, P-256, RSA-4096).

Quick Start

Generate a Mnemonic

// src/Common/Sorcha.Wallet.Core/Domain/ValueObjects/Mnemonic.cs
var mnemonic = Mnemonic.Generate(12);  // or 24 for higher security
// NEVER log mnemonic.Phrase - use mnemonic.ToString() which returns "Mnemonic(12 words)"
