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 native Segwit address
• Create a 1-to-1 Transaction
• Create a 2-to-2 Transaction
• 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

• Add asset creation, transactions

Running the test suite

pub run test

Complementing Libraries
