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 MSFTx multiplier steps up. The vault program reads the test mint's multiplier onchain and releases the added units to dMSFTx holders. The last real MSFTx bump took the multiplier from 1.004582 to 1.005903.
