NanoJs is a simple, modern and secure library for nanocurrency.

Features

• Secure by default. No sharing of private_key, all the blocks are created and signed locally. then get published to node.
• Get account information, balance, pending blocks, etc.
• Send, and Receive nano.
• Create wallet, account (with and without seed).
• Work Generate, block info, publish block to node, etc.
• xno to raw and vice-versa.
