nanopy 28.0.1.post13

Python implementation of NANO currency related functions

nanopy

nanopy includes C extensions for work generation and signing, and therefore needs a compiler to install.

sudo apt install gcc python3-dev
pip install nanopy

When needed, use the environment variables CC, LDSHARED, CFLAGS, and LDFLAGS to tweak build options. See setuptools documentation for further info.

GPU support can be enabled with USE_OCL=1 and appropriate OpenCL dependencies.

sudo apt install gcc python3-dev ocl-icd-opencl-dev intel/mesa/nvidia/pocl/rocm-opencl-icd
USE_OCL=1 pip install nanopy

• Install mnemonic to generate mnemonic wallets.
• Install requests or websocket-client to use http or websocket RPC, respectively.

Usage

# create an account (defaults to NANO network) and set secret key
seed = "0000000...."
acc = npy.Account()
acc.sk = npy.deterministic_key(seed)

# if it is not a new account, set the current state of the account (frontier, raw bal, rep)
acc.state = ("1234....", 1200000000000000, npy.Account(addr="nano_repaddress..."))

# create a receive block and optionally, change rep along with it
_hash = "5678...."
raw_amt = acc.network.to_raw("10")
rep = npy.Account(addr="nano_newrepaddress...")
rb = acc.receive(_hash, raw_amt, rep)

# create a send block
to = npy.Account(addr="nano_sendaddress...")
raw_amt = acc.network.to_raw("1")
sb = acc.send(to, raw_amt)

# broadcast
rpc.process(rb.json)
rpc.process(sb.json)

Wallet

A cli wallet is included with the library

• Configuration is in ~/.config/nanopy.ini

[nano]
nano_1111111111111111111111111111111111111111111111111111hifc8npp
nano_16aj46aj46aj46aj46aj46aj46aj46aj46aj46aj46aj46aj46ajbtsyew7c
rpc = http://localhost:7076

• -n, --network. Choose the network to interact with - nano, banano, or beta. The default network is nano.
• Checks state of accounts in ~/.config/nanopy.ini by default.
• Open a wallet, nanopy-wallet open FILE KEY. KEY is a seed in a KDBX FILE. See nanopy-wallet open -h for options.
