BlackRock and Vanguard portfolio models, reflected onchain

BlackRock and Vanguard have built portfolio models for investors with different goals and levels of risk. Those models turn a broad market view into a practical allocation across equities, bonds and cash.

Mast Bond is preparing onchain portfolios that reflect these institutional allocation models. We plan to source model data through licensed third-party providers, map each allocation to assets available on Robinhood Chain and package the result into one transparent position.

From institutional model to Mast vault

A user will choose a model by objective and risk level, deposit USDG and receive vault shares representing the complete portfolio. Mast will handle the allocation inside the vault.

Each model page will identify the investment manager associated with the source allocation, the model date and the target weights. It will also show the assets used by Mast, any substitutions and the complete rebalance history.

What an onchain reflection means

A Mast Model will follow the risk structure and asset allocation of its source model. The onchain holdings may differ because Robinhood Chain supports a different investment universe.

A global balanced model might call for US equities, international equities, broad bonds and short-term reserves. Mast will use the closest supported exposure for each part of the allocation and disclose the difference before a user invests.

This approach gives users a recognisable portfolio framework while keeping the onchain implementation open for inspection.

Built for total return

Mast Models will give users exposure to the performance and income of the assets in each portfolio. The result will depend on market movement, portfolio income and vault fees.

Users will see their vault-share balance, current position value and historical performance. Portfolio values can rise or fall, and market-based models do not carry a promised APY.

Clear sourcing and attribution

Mast will obtain allocation and rebalance data through third-party model providers with the required rights. The provider supplies the licensed data. Mast Bond builds and operates the onchain vault.

References to BlackRock, Vanguard or another manager identify the model being reflected. They do not state that the manager sponsors, endorses or operates Mast Bond unless Mast publishes a separate agreement confirming that relationship.

The next Mast Models

The first lineup will focus on conservative, balanced and growth allocations. Mast will publish the source model, onchain mapping and risk information for each vault before deposits open.

The goal is straightforward: give Robinhood Chain users access to portfolio structures associated with the world's largest investment managers through one position they can inspect onchain.
