Pyslopes - The AVA Platform Python Library

Overview

Pyslopes is a Python Library for interfacing with the AVA Platform. The Pyslopes library allows one to issue commands to the AVA node APIs.

The APIs currently supported by default are:

• The AVA Virtual Machine (AVM) API
• The Keystore API
• The Admin API
• The Platform API

Getting Started

We built Pyslopes with ease of use in mind. With this library, any Python developer is able to interact with a node on the AVA Platform who has enabled their API endpoints for the developer's consumption. We keep the library up-to-date with the latest changes in the AVA Platform Specification.

Using Pyslopes, developers are able to:

• Locally manage private keys
• Retrieve balances on addresses
• Get UTXOs for addresses
• Build and sign transactions
• Issue signed transactions to the AVM
• Create a subnetwork
• Administer a local node
• Retrieve AVA network information from a node

Requirements

Pyslopes requires Python3.

Installation

Just import Pyslopes files

import sys
LIB_PATH = "/PATH/TO/PYSLOPES/pyslopes/src/apis"
sys.path.insert(1, LIB_PATH)
import admin, avm, keystore, platform_pchain
from admin import api as admin
from avm import api as avm
from keystore import api as keystore
from platform_pchain import api as platform

Example — Sending An Asset

This example sends an asset in the AVM to a single recipient.

Create users & keys

make users and keys to send & receive asset

API_NODE_IP = "http://127.0.0.1:9650"
usernames = list(["user1", "user2"])
passwords = list(["POWERFUL_PASSWORD1", "POWERFUL_PASSWORD2"])
addresses = list()
for i in range(len(usernames)):
  keystore.createUser(API_NODE_IP, usernames[i], password[i])
  addresses.append(avm.createAddress(API_NODE_IP, usernames[i], passwords[i]))

Get balances

check the balance of addresses

for i in range(len(usernames)):
  print(usernames[i], addresses[i], "balance:", avm.getAllBalances(API_NODE_IP, addresses[i]))

Send AVA

send AVA asset from user1 to user2

avm.send(API_NODE_IP, 50000, "AVA", addresses[1], usernames[0], passwords[0], [addresses[0]])
