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.
Three ways nectarengine simplifies sidechain development.
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.
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.
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.
Requires Python >= 3.10.
