What is Xian? ​

Xian is a Python-first decentralized application platform for building programmable networks, simple but powerful smart contracts, and software-friendly integration layers around them.

It should be thought of as decentralized infrastructure that can be used like a tool: run an application-specific network, expose programmable shared state, and integrate it with normal backend systems without adopting a highly specialized contract stack.

Key Features ​

  • Python-friendly smart contracts -- a restricted, deterministic subset of Python that is easier to learn and audit than most contract-specific languages
  • Programmable decentralized networks -- compose networks and runtime policies around your application instead of treating the chain as a fixed black box
  • Software-friendly integration -- SDKs, indexed reads, monitoring, snapshots, and deployment tooling help Xian fit into real applications and operations workflows
  • Deterministic execution -- metered execution, stable context values, and restricted runtime rules keep contract behavior predictable across validators
  • Structured state and events -- persistent state, cross-contract calls, and event emission support real application backends, observers, and automation
