Hdwallet

HDWallet is an open-source C#/.NET library for generating hierarchical deterministic cryptocurrency wallets and deriving account, deposit and change-wallet paths. It supports Secp256k1, Secp256r1 and Ed25519, and accepts mnemonics, extended private keys or private keys as inputs. A separate .NET Core or Docker-hosted API is described for address-generation requests.

Understand the project

Practical overview

When it fits

Use HDWallet when implementing wallet key derivation in a .NET application, particularly when one mnemonic must produce multiple wallet paths or networks. Choose the SDK for embedded derivation; consider the separate API when an application needs address-generation requests.

Who it is for

  • .NET developers embedding deterministic wallet derivation in crypto applications.
  • Teams building multi-network wallet components that need account and deposit/change derivation.
  • Developers extending wallet derivation to supported curve families with a specified purpose and coin type.

Documented uses

  • Create HD wallets from a mnemonic with or without a passphrase.
  • Derive subaccounts and external deposit or internal change wallets.
  • Recreate addresses deterministically from supplied wallet secrets instead of storing private keys for multiple addresses.
  • Create non-HD wallets from private keys.
  • Request address generation through the separately described API.
Before you choose

Requirements & limits

The public GitHub repository identifies the project as MIT-licensed open-source software.

  • The application must provide the mnemonic, seed or private key; the library does not store secrets or manage wallets.
  • Address creation depends on implementing an address generator for the relevant cryptocurrency.
  • Litecoin, Dash and Dogecoin are described as Bitcoin-like support in progress.
  • The sign server is marked work in progress in the README.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Derive a Bitcoin deposit wallet with the .NET SDK

Create the first external wallet under the first Bitcoin account from a mnemonic.

Before you start

  • .NET development environment
  • A mnemonic supplied by the application

Steps

  1. Create a Bitcoin HD wallet from the mnemonic.

  2. Select account 0 with GetAccount(0).

  3. Select external wallet 0 with GetExternalWallet(0).

  4. Read the wallet's Address property; address generation depends on an address generator for the cryptocurrency.

Expected outcome

A derived first external Bitcoin wallet and its address, when the relevant address generator is implemented.

Guide limitations

  • The library does not store secrets or manage the wallet.
  • The mnemonic example in the README is illustrative; use an appropriate secret for the application.
