# Collateral Supply Limits

As ETH will be the first non-USDC collateral supported for this feature, we are taking a measured approach with conservative user and global supply limits, which can be found within this section. As the product matures over time with deeper spot liquidity and growing USDC supply, we plan to expand supported assets and introduce additional features.

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