# Deploying Contracts

Deploying a Neo N3 smart contract requires two artifacts produced by `neo-solc`:

- `<contract>.nef` -- the NeoVM bytecode
- `<contract>.manifest.json` -- the ABI, permissions, and metadata

This page covers the Neo N3 deployment model, local deployment with Neo-Express, constructor arguments, contract upgrades, and production deployment considerations.
