Welcome to Mast Bond

Mast Bond turns one USDG deposit into a diversified onchain portfolio. You choose the risk mix, receive vault shares, and keep a clear view of what you own.

The first release brings stock indexes, short-term US government bonds, silver, and USDG together on Robinhood Chain. Each portfolio uses the same assets in a different mix.

Choose your portfolio

Defensive places more weight on government bonds and USDG. Balanced spreads risk across the full basket. Growth gives stock indexes a larger role. Adaptive can adjust its target mix using market rules, with an AI check that can only make the allocation more defensive.

You can also create a custom portfolio. Set the SPY, QQQ, SGOV, and SLV weights yourself; any amount left over stays in USDG.

What your vault shares mean

When you invest USDG, the vault mints portfolio shares to your wallet. Those shares represent your proportional claim on the vault. Their value follows the basket after fees and market movement.

A withdrawal burns your portfolio shares. The vault returns USDG when enough settlement liquidity is available, with an in-kind path for the underlying assets when needed. Values can rise or fall.

How Portfolio Boost works

Stake mDEF, mBAL, mGRO, mADP, or eligible custom-vault shares in the matching Boost pool. When a pool receives fee-funded rewards, it pays them as additional shares in that same portfolio.

Locking MAST beside your portfolio is optional. It can raise your reward weight up to 2×, which increases your share of a funded reward period. MAST does not change the value or market performance of the shares you already hold.

The introductory fee rebate

For the first few weeks after Boost rewards open, Mast Bond plans to rebate the 0.35% annual management fee accrued on eligible portfolio shares while they remain staked. The rebate will be funded and distributed in the corresponding portfolio shares.

We will publish the campaign start and end dates, eligible pools, and funding transactions before distributions begin. Until then, the rebate is an announced launch programme, not an active or guaranteed reward.

Start with USDG

Connect a wallet on Robinhood Chain, choose a portfolio, enter the USDG amount, and review the transaction in your wallet. The interface shows your share balance, current value, and fee-adjusted return after the position is confirmed.

Read the risk before you invest

Mast Bond is an early, unaudited protocol. Portfolio assets, tokenized instruments, oracles, smart contracts, and market liquidity all carry risk. Historical illustrations are not forecasts, rewards depend on actual pool funding, and no APY is promised.
