# Security Your silver, gold and platinum will be stored in formally recognised bullion storage facilities, managed by specialist vault operators who are leading providers of precious metal vault services and secure transportation around the world. Professional market vault operators produce what is called a Bar List. It's a bit like a bank statement, listing the account holder's stock of bars, and showing both the silver, fine gold, platinum or palladium content of each bar and the total amount of bullion held. We publish the bar lists produced by the vault operators for BullionVault users' bullion. Sparklo will maintain the ownership records of all that bullion. Each day we will publish online our daily register of owners, although we hide your identity by listing your holding against your alias. We also publish the total, and naturally the total matches the total on the bar list. --- # 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.
