# 7.2 Contract Engine

At the heart of Nucleus AI is a set of modular **smart contract templates** designed for fast generation, customization, and secure deployment.

These templates cover:

* ERC-20 / BEP-20 token contracts
* Staking and yield farming logic
* DAO voting and governance modules
* NFT minting and batch airdrop contracts
* Vesting, locking, and liquidity tools

**Automation Logic** ensures that parameters selected via UI are accurately injected into contract blueprints. All generated contracts go through AI auditing before deployment, and they are optimized for gas efficiency and compatibility with major explorers and DEXs.

Contracts are also **upgradable**, allowing future extensions through proxy patterns and standard migration flows.
