Read full descriptionHide full description
TBA Vault Watcher is a read-only iOS app for monitoring Bitcoin vaults. The app lets users import a wallet configuration file containing only public information (such as extended public keys and descriptors) to view balances and transaction history. TBA Vault Watcher cannot access private keys, cannot sign transactions, cannot move or transmit funds, and includes no cryptocurrency exchange, trading, or custody features of any kind. It provides no financial services. All data is stored locally on the device. No accounts are required, and no data is collected or transmitted to any server. This app gives users independent, secure visibility into their Bitcoin vaults without adding any security risk.
