# Collateral Supply Limits

We are taking a measured approach to non-USDC collateral, starting with conservative user and global supply limits outlined in this section. As the product matures, spot liquidity deepens, and USDC supply grows, we plan to support additional collateral assets and introduce new features.

Important note: users can choose *how much* of their available collateral to allocate as margin on a per-asset basis.

#### Global Supply Limit Caps
