Regional availability

New transactions are not available in the United States or to U.S. persons. No identity documents are requested.

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

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.
