The Wallet SDK lets an estate property show a Flashy Gold balance and take consent-gated actions without rebuilding custody. It talks to the Rails API and defers signing and consent to the wallet and flashyID, so your product never touches a key.
What you get
A balance component, a redeem/pay flow that drafts an action and hands it to the user for approval, and a grant flow for capped, delegated spend. The SDK renders the estate design system so it reads as one house.
