The decision of whether to deposit 100% ETH or 100% WSTETH into the WSTETH Eth Vault is ultimately up to you, as it depends on your individual risk tolerance and financial goals. The Vaultcard provides an overview of the security score of the Vault, which can help you decide whether it is the right option for you. It is also important to note that the Vault will automatically maintain an approximate 50/50 balance of both tokens, so you should consider how this balance aligns with your financial goals when making your decision. Ultimately, it is important to make an informed decision that is tailored to your individual needs and risk tolerance.
