# Vault Assets

Aera Vaults are developed to hold and rebalance two or more ERC20 assets. For v1, the two assets used are ETH (specifically WETH) and USDC. From our research, we have concluded that most crypto assets have strong inter-correlation and we feel that ETH and USDC capture two important components and can mimic the essential price behavior of a wider class of assets while showing more stability as a reserve asset.
