What does “U.S. person” mean?

For an individual, Regulation S generally looks at U.S. residence, not citizenship alone. It also covers certain entities, trusts, estates and accounts. Read the full definition before confirming if you are unsure.

Before a new transaction, sign the eligibility declaration in your wallet. This costs no gas and does not authorize a transfer. Confirmation lasts up to 24 hours; location is checked again before new transactions. Terms · Privacy

How does the pair stay balanced?

Your target split is set when you create the portfolio. Rebalancing can run when an asset drifts more than 2.5 percentage points from its target, at most once per day. It sells part of the overweight asset to buy the other.

A keeper or any caller can trigger the same contract rules. Execution requires current prices, available liquidity and network fees. Rebalancing is not guaranteed to run immediately. As owner, you can change the operator through your contract.

What do I own, and how do I withdraw?

Your wallet owns the portfolio and receives mPAIR shares. Each portfolio has its own contract, even though the share symbol is the same. Withdraw into USDG or receive both underlying tokens and any uninvested USDG.

The holdings are Robinhood Stock Tokens providing exposure to ETFs. They do not give you direct ownership of stocks, bonds or physical silver.

Fees and investment risks

The annual portfolio fee is 0.35%. Trading and network costs also apply. Both assets can lose value together. Rebalancing does not guarantee a profit or prevent losses.

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.
