Deposit a test xStock into the vault program. Get a share token that keeps the base value and a dividend token that collects every multiplier bump for 12 months.
When Backed applies a dividend on mainnet, the QQQx multiplier steps up. The vault program reads the test mint's multiplier onchain and releases the added units to dQQQx holders. The last real QQQx bump took the multiplier from 1.002725 to 1.003456.
