Creation costs a network fee. Then enter your USDG amount to buy the assets together.

Checking portfolio availability…

What do I own and how do I withdraw?

Your wallet owns a separate portfolio contract and receives mMIX shares. Withdraw into USDG or receive your proportion of each underlying token. Tokens provide exposure to stocks and ETFs; they do not give you direct ownership of the underlying securities.

Why are some assets unavailable?

Each enabled asset needs a published onchain price feed and a USDG pool that passed execution checks. Availability can change with prices, corporate actions and liquidity. The catalogue includes Robinhood Chain stock tokens, not every security in the Robinhood app.

Fees, prices and rebalancing

The annual portfolio fee is 0.35%, plus trading and network costs. The daily keeper only acts if you enable it; execution depends on prices, liquidity and its gas budget. Prices follow the stock token’s feed and may carry over market closures. Your investment can lose value.

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.
