Smart contracts & XVM

Smart contracts on XELIS run on XVM (XELIS Virtual Machine) and are written in Silex, a statically typed language documented on the official site.

Rollout status

Check Development status for tasks such as Smart Contract integration (listed as in progress as of March 2026). The FAQ answers high-level questions about XVM / smart contracts and links xelis-vm.

Some older paragraphs on the docs introduction or funding sections may still mention smart contracts as a future milestone; treat FAQ, development-status, and network-upgrades as the fresher signals for what is live on which network.

For educators

• Pin examples to a specific software release or commit when showing bytecode or RPC behavior.
• Prefer the Playground for syntax lessons before mainnet deployment discussions.
