# Security Tiers & Deployment Models

> Flexible security configurations for different integration requirements

## Overview

Yield.xyz offers a flexible, tiered security model designed to meet the needs of different partners — from hosted widget integrations to regulated institutional environments.

Each tier combines **Shield**, **HyperNative**, and optional hardware-secure deployments to balance ease of integration, transaction safety, and compliance assurance.
