Because of our protocol’s design, we cannot compute TVL by reading objects directly, it must be derived from event emissions. This PR follows the same approach as Haedal vaults by fetching vault metadata from API and helper to aggregate balances. Please understand this is the only feasible way to calculate TVL on our protocol, and future changes can simply adjust the packageId or API endpoint without modifying on-chain logic. Thank you for understanding🙏
