⚙️ nectarengine

The modern Python library for Hive Engine tokens. Built for production. Made to last.

nectarengine is the high-performance companion to Nectar, specifically designed for interacting with the Hive Engine sidechain. While Nectar handles the core blockchain layer, nectarengine provides an opinionated, resilient, and simplified interface for token operations, market trading, and NFT management.

If you are building on Hive Engine, nectarengine is the tool you need.

Why nectarengine?

Three ways nectarengine simplifies sidechain development.

⚡ Built on Nectar

nectarengine is built on top of Nectar, inheriting its modern cryptography, connection pooling, and resilient transport layers. It replaces legacy sidechain tools with a clean, typed API.

🐳 Container-Native & Serverless Ready

Inheriting Nectar's philosophy, nectarengine is designed to run anywhere. It handles environment-specific challenges—like read-only filesystems in Docker or Kubernetes—by defaulting to in-memory fallbacks when local storage is unavailable.

🪙 Unified Sidechain Interface

Forget complex JSON-RPC calls. nectarengine provides dedicated objects for:

• Tokens: Easy balance checks, transfers, and metadata lookups.
• Market: Seamless buy/sell orders and order book management.
• NFTs: Comprehensive support for minting, transferring, and querying digital assets.

🚀 Quick Start

Requires Python >= 3.10.

pip install nectarengine

Get sidechain status

from nectarengine.api import Api

api = Api()
print(f"Latest Block: {api.get_latest_block_info()['blockNumber']}")

Send Tokens

from nectar import Hive
from nectarengine.wallet import Wallet

# Initialize Hive with your active key
hive = Hive(keys=["your-active-private-key"])

# Create a wallet for the account
wallet = Wallet("youraccount", blockchain_instance=hive)

# Transfer 1.0 BEE to a recipient
wallet.transfer("recipient", 1.0, "BEE", memo="Sent with nectarengine")

Trade on the Market

from nectar import Hive
from nectarengine.market import Market

hive = Hive(keys=["your-active-private-key"])
market = Market(blockchain_instance=hive)

# Buy 100 SWAP.HIVE with BEE at a price of 0.5
market.buy("youraccount", 100, "SWAP.HIVE", 0.5)

🛠️ System Prerequisites

On platforms where binary wheels for coincurve and cryptography are not precompiled, build tools are required to compile the C extensions.

Debian / Ubuntu

sudo apt-get install build-essential libssl-dev python3-dev python3-pip libffi-dev libtool autoconf automake pkg-config

Fedora / RHEL

sudo dnf install gcc openssl-devel python3-devel libffi-devel libtool autoconf automake pkgconfig
