Challenge

When a PE fund winds down, the manager (GP) can move a still-valuable company into a new continuation fund. Investors either cash out or roll over, and a secondary buyer brings fresh capital. But the GP sits on both sides of the deal, and today the checks on that conflict live in emails, PDFs and a data room the GP controls.

Scope

• Product concept and deal flow for six independent parties
• Role-based web app: GP, buyers, exiting and rolling investors, LPAC, independent valuer
• Ledger inspector and live transaction feed as proof of what happened
• 14-slide pitch deck
• Brand: logo and visual language

Process

• Built for the Encode Club “Build on Canton” hackathon by a team of two: I led product and design, Kirill led engineering.
• Everything was made with AI — no hand-drawn mockups and no hand-written code.
• On Canton: Daml smart contracts model the whole deal lifecycle — independent valuation, sealed-bid auction, LPAC consent and private LP elections.
• Canton’s per-party privacy means buyers and investors see only their own slice: bids stay sealed, elections stay private, the LPAC gets a scoped fairness view.
• The close is a single atomic Canton transaction: cash out, new fund units in, rolled units and burned old interests — every leg settles, or none does.
• Each party signs with its own key through a separate custodian; the browser never holds key material.

Outcomes

• Working demo on Canton devnet
• One-transaction close with on-ledger proof for auditors
