# Cross-chain Deployments ### What are Cross Chain Deployments? Cross-chain deployments allow one Aera vault to access assets on other chains by leveraging other Aera vaults on those chains. Cross-chain deployments mean that each chain has an independent Aera vault with its own guardians and assets. However, the vaults on chains other than the parent vault are just `BaseVault` contracts since they don't need to collect fees separately or even support withdrawals/deposits. ### Why They Matter Cross-chain access is crucial for incorporating unique assets, finding liquidity for long-tail assets and tapping into the best yields. ### How to do a Cross Chain Deployment Cross-chain deployments should be planned carefully taking into account the behavior of assets on every chain involved but here is a list of concerns to think about: * Which chains will be used and whether to use `BaseVault` or another type of vault on those chains? * Is there a risk of assets becoming irretrievable? * What address will be the vault owner and guardian on non-parent chains? * How will the account take into account the value on other chains and value that is moving across the bridge? ### Caveats Cross-chain deployments can be very risky depending on the specific bridge used. Cross-chain deployments to non-EVM chains are not currently supported. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
