The below examples are implemented as integration tests:
- Generate a random address
- Validating address
- Generate an address from a SHA256 hash
- Import an address via WIF
- Generate a Testnet address
- Generate a Litecoin address
- Generate a Segwit address
- Generate a Segwit Testnet address
- Generate a Segwit address (via P2SH)
- Create a 1-to-1 Transaction
- Create a 2-to-2 Transaction
- Create a Transaction with a SegWit P2SH(P2WPKH) input
- Create a Transaction with a SegWit P2WPKH input
- Import a BIP32 testnet xpriv and export to WIF
- Export a BIP32 xpriv, then import it
- Export a BIP32 xpub
- Create a BIP32, bitcoin, account 0, external address
- Create a BIP44, bitcoin, account 0, external address
- Use BIP39 to generate BIP32 addresses
TODO #
- Generate a SegWit multisig address
