SproutFi is building family-owned portfolios for tokenized stocks on Robinhood Chain.

A parent creates a dedicated on-chain vault for a child, selects from the supported asset mix, and funds it directly. Family members can contribute through gift links, while parents can create milestone rewards for things like chores, birthdays, or small achievements. The goal is to give small contributions a place to stay, rather than letting them disappear after the moment has passed.

The technical side is built around ownership and limits. Each Sprout is created through a contract factory with a beneficiary, approved assets, defined permissions, and an immutable graduation timestamp. Parents can guide the vault before graduation, but they cannot simply withdraw the portfolio back to themselves. Gifts add funds without giving the sender control. When the graduation date arrives, parent permissions end and the beneficiary becomes the only party with withdrawal rights.

Balances, permissions, milestones, gifts, and graduation rules live on-chain. The dashboard is there to make the portfolio easier to follow, while the vault remains the source of truth. SproutFi also uses configured asset and venue admission, wallet-signed transactions, price and quote checks, and safeguards for small balances so family contributions can work at any size.
