Method and sources

Calendar-year total returns used in the illustration:

Asset20212022202320242025
SPY5 proxy+28.3%-18.4%+25.9%+24.7%+17.6%
QQQ+27.2%-32.5%+54.8%+25.6%+20.8%
SGOV+0.0%+1.6%+5.1%+5.3%+4.2%
SLV-13.3%+3.2%-1.1%+20.9%+147.9%

Important: SPY uses State Street’s SPY5 share class as a proxy. SLV’s +147.9% result in 2025 is an exceptional outlier. Robinhood Stock Tokens are debt securities and may not track these ETFs exactly.

How this portfolio works
Rebalancing—
Contract0x9e0c…fe67 · Chain 4663

Deposits swap USDG into the full basket. Normal withdrawals sell your share back to USDG. The direct asset withdrawal remains available if swaps or price feeds stop. Stock Tokens are tokenised debt securities, not direct ownership of the underlying shares. Initial-release contracts audited by CTA; value can fall.

Mast Bond

A portfolio, not another yield vault.

Mast Bond converts one USDG deposit into a portfolio of stock indexes, government bonds, silver, and cash. The goal is long-term total return, not a fixed or promised APY.

Pick your mix

Choose Defensive, Balanced, Growth, Adaptive, or set every percentage yourself.

Invest once

The vault automatically buys the mix and sends portfolio shares to your wallet.

Track one position

See its current USDG value and verified return. Withdraw to USDG or receive the underlying assets.

Portfolio returns appear in the vault NAV. In Portfolio Boost, users can stake vault shares and optionally add MAST for a larger portion of fee-funded share rewards. Your position shows verified cost basis and current return when the shares were acquired through Mast Bond. Historical illustrations are not forecasts. The annual vault fee is 0.35%. Stock Tokens are tokenised debt securities, and value can fall.
